Occurrence and fate of antibiotics in advanced wastewater treatment facilities and receiving rivers in

Xinwei LI,Hanchang SHI,Kuixiao LI,Liang ZHANG,Yiping GAN

《环境科学与工程前沿（英文）》 2014年 第8卷 第6期   页码 888-894 doi: 10.1007/s11783-014-0735-0

摘要： The occurrence and removal of 13 antibiotics were investigated in five wastewater treatment plants (WWTPs) with advanced wastewater treatment processes in Beijing, China. Most of the target antibiotics were detected in the secondary and tertiary effluents, with the concentrations of 4.8–1106.0 and 0.3–505.0 ng·L . Fluoroquinolone antibiotics showed relatively high concentrations in all samples (782–1814 ng·L ). Different tertiary treatment processes showed discrepant antibiotics removal performances. Ozonation process was found more effective in removing target antibiotics compared to the coagulation-flocculation-sedimentation process and sand filtration process. Investigation of the target antibiotics in three typical urban rivers in Beijing was carried out to understand antibiotics occurrence in surface water environment. Eight antibiotics were detected in the studied rivers, with highest concentration of antibiotics in the river which was mainly replenished by reclaimed water. This study showed the necessity of employing more effective advanced treatment facilities to further reduce the discharge amount of antibiotics.

Increasing significance of advanced physical/chemical processes in the development and application ofsustainable wastewater treatment systems

RULKENS Wim

《环境科学与工程前沿（英文）》 2008年 第2卷 第4期   页码 385-396 doi: 10.1007/s11783-008-0073-1

摘要： The awareness of the problem of the scarcity of water of high quality has strongly changed the approach of wastewater treatment. Currently, there is an increasing need for the beneficial reuse of treated wastewater and to recover valuable products and energy from the wastewater. Because microbiological treatment methods are, only to a limited part, able to satisfy these needs, the role and significance of physical/chemical processes in wastewater treatment are gaining more and more interest. The specific future role and aim of the various physical/chemical treatment processes can be categorized in five groups: improvement of the performance of microbiological treatment processes, achievement of the high quality required for reuse of the effluent, recovery of valuable components and energy from the wastewater for beneficial reuse, desalination of brackish water and seawater, and treatment of concentrated liquid or solid waste residues produced in a wastewater treatment process. Development of more environmentally sustainable wastewater treatment chains in which physical/chemical processes play a crucial role, also requires application of process control and modeling strategies. This is briefly introduced by the elaboration of treatment scenarios for three specific wastewaters.

Combined process of biofiltration and ozone oxidation as an advanced treatment process for wastewater

Xinwei LI,Hanchang SHI,Kuixiao LI,Liang ZHANG

《环境科学与工程前沿（英文）》 2015年 第9卷 第6期   页码 1076-1083 doi: 10.1007/s11783-015-0770-5

摘要： The effluent of a wastewater treatment plant was treated in a pilot plant for reclaimed water production through the denitrification biofilter (DNBF) process, ozonation (O ), and biologic aerated filtration (BAF). The combined process demonstrated good removal performance of conventional pollutants, including concentrations of chemical oxygen demand (27.8 mg·L ) and total nitrogen (9.9 mg·L ) in the final effluent, which met the local discharge standards and water reuse purposes. Micropollutants (e.g., antibiotics and endocrine-disrupting chemicals) were also significantly removed during the proposed process. Ozonation exhibited high antibiotic removal efficiencies, especially for tetracycline (94%). However, micropollutant removal efficiency was negatively affected by the nitrite produced by DNBF. Acute toxicity variations of the combined process were estimated by utilizing luminescent bacteria. Inhibition rate increased from 9% to 15% during ozonation. Carbonyl compound concentrations (e.g., aldehydes and ketones) also increased by 58% as by-products, which consequently increased toxicity. However, toxicity eventually became as low as that of the influent because the by-products were effectively removed by BAF. The combined DNBF/O /BAF process is suitable for the advanced treatment of reclaimed water because it can thoroughly remove pollutants and toxicity.

Treatment of advanced non-small cell lung cancer with driver mutations: current applications and future

《医学前沿（英文）》 2023年 第17卷 第1期   页码 18-42 doi: 10.1007/s11684-022-0976-4

摘要： With the improved understanding of driver mutations in non-small cell lung cancer (NSCLC), expanding the targeted therapeutic options improved the survival and safety. However, responses to these agents are commonly temporary and incomplete. Moreover, even patients with the same oncogenic driver gene can respond diversely to the same agent. Furthermore, the therapeutic role of immune-checkpoint inhibitors (ICIs) in oncogene-driven NSCLC remains unclear. Therefore, this review aimed to classify the management of NSCLC with driver mutations based on the gene subtype, concomitant mutation, and dynamic alternation. Then, we provide an overview of the resistant mechanism of target therapy occurring in targeted alternations (“target-dependent resistance”) and in the parallel and downstream pathways (“target-independent resistance”). Thirdly, we discuss the effectiveness of ICIs for NSCLC with driver mutations and the combined therapeutic approaches that might reverse the immunosuppressive tumor immune microenvironment. Finally, we listed the emerging treatment strategies for the new oncogenic alternations, and proposed the perspective of NSCLC with driver mutations. This review will guide clinicians to design tailored treatments for NSCLC with driver mutations.

《环境科学与工程前沿（英文）》 2014年 第8卷 第2期   页码 188-194 doi: 10.1007/s11783-013-0544-x

摘要： The oxidation of aqueous monochlorobenzene (MCB) solutions using thermally- activated persulfate has been investigated. The influence of reaction temperature on the kinetics of MCB oxidation was examined, and the Arrenhius Equation rate constants at 20°C, 30°C, 40°C, 50°C, and 60°C for MCB oxidation performance were calculated as 0, 0.001, 0.002, 0.015, 0.057 min , which indicates that elevated temperature accelerated the rate. The most efficient molar ratio of persulfate/MCB for MCB oxidation was determined to be 200 to 1 and an increase in the rate constants suggests that the oxidation process proceeded more rapidly with increasing persulfate/MCB molar ratios. In addition, the reactivity of persulfate in contaminated water is partly influenced by the presence of background ions such as Cl , , , and . Importantly, a scavenging effect in rate constant was observed for both Cl and but not for other ions. The effective thermally activated persulfate oxidation of MCB in groundwater from a real contaminated site was achieved using both elevated reaction temperature and increased persulfate/MCB molar ratio.

《医学前沿（英文）》 2008年 第2卷 第2期   页码 134-138 doi: 10.1007/s11684-008-0025-y

摘要： The aim of this paper is to evaluate the efficacy of the surgical treatment for advanced hilar cholangiocarcinoma (CCA) in order to improve the resection rate and curative effect. A retrospective analysis was performed on the data of 24 patients who had undergone surgical treatment for advanced hilar CCA. According to the Bismuth classification, there were four cases of type IIIa, six cases of type IIIb, and 14 cases of type IV. Based on the treatment approaches, these patients were divided into three groups: $` Radical resection group: There were five cases (one type IIIa, three type IIIb, and one type IV). The tumor visible to the naked eyes was resected thoroughly and the cut margin was free of tumor by microscopic examination. Then, Roux-en-Y hepatico-jejunal anastomosis was performed to restore the bile flow. $a Palliative resection group: There were 11 cases. The bile flow was restored by Roux-en-Y hepatico-jejunal anastomosis directly in five cases (two type IIIa, three type IIIb) and by internal drainage through a hepatico-jejunal bridge in the other six cases (one type IIIa, five type IV). $b Simple internal biliary drainage group: There were eight cases of type IV, including three cases with the internal drainage through hepatico-jejunal bridge by laparotomy, three cases with endoscopic retrograde biliary drainage (ERBD), two cases with percutaneous transhepatic biliary drainage (PTBD). The rate of radical resection was 20.8% and the overall resection rate was 66.7%. All of the 24 patients were followed-up. The cumulative surviving rates were significantly different among these three groups (Log-rank = 17.56, = 0.0002). For advanced hilar CCA, the best choice of treatment is radical resection. If radical resection is impractical, palliative resection combined with partial hepatectomy can significantly prolong the survival time. Internal drainage through a hepatico-jejunal bridge can enhance the surgical resection rate and decrease the occurrence rate of postoperative biliary leakage.

《环境科学与工程前沿（英文）》 2014年 第8卷 第1期   页码 62-68 doi: 10.1007/s11783-013-0518-z

摘要： The application of appropriate advanced treatment process in the municipal wastewater treatment plants (WWTPs) has become an important issue considering the elimination of emerging contaminants, such as pharmaceutical and personal care products (PPCPs). In the present study, the removal of 13 PPCPs belonging to different therapeutic classes by the sequential ultraviolet (UV) and ozonation process in a full-scale WWTP in Beijing was investigated over the course of ten months. Most of the target PPCPs were effectively removed, and the median removal efficiencies of individual PPCPs, ranging from -13% to 89%, were dependent on their reaction rate constants with molecular ozone. Noticeable fluctuation in the removal efficiencies of the same PPCPs was observed in different sampling campaigns. Nevertheless, the sequential UV and ozonation process still made a significant contribution to the total elimination of most PPCPs in the full-scale WWTP, by compensating for the poor or fluctuant removal performance of PPCPs by biologic treatment process.

摘要：

2,4-二硝基茴香醚（DNAN）是用于替代2,4,6-三硝基甲苯（TNT）的钝感炸药的一种重要成分。为了研究初始pH和过氧化氢（H2O2）剂量对DNAN降解动力学和降解途径的影响，开展了DNAN的光催化H2O2氧化实验。结果显示，初始pH为4~7且H2O2剂量为1500~4500 ppm，使用UV/ H2O2处理浓度为250 ppm的DNAN溶液时，DNAN的降解服从零级反应动力学。但是，当H2O2剂量为750 ppm时，DNAN的降解服从类一级反应动力学。结果表明，DNAN易于被UV/H2O2氧化降解。当H2O2剂量为1500 ppm且初始pH为7时，3 h内DNAN浓度从250 ppm降到1 ppm以内；但3 h内总有机碳（TOC）和总碳（TC）浓度从100 ppm降到70 ppm以下，9 h后降到5 ppm以下，说明生成了其他有机化合物。这些中间产物氧化为CO2的速度慢于DNAN的氧化速度。UV/H2O2氧化过程中，生成的CO2释放到空气中，因为溶液pH迅速降低到3左右。9 h的UV/H2O2处理后，DNAN中的N绝大多数转化为硝态氮。研究表明，UV/H2O2氧化是处理DNAN废水的有效技术。

Transfer-Promoted Fe2+/Fe3+ Circulation Steered by 3D Flow-Through Co-Catalyst System Toward Sustainable Advanced

Weiyang Lv,Hao Li,Jinhui Wang,Lixin Wang,Zenglong Wu,Yuge Wang,Wenkai Song,Wenkai Cheng,Yuyuan Yao,

摘要： Realizing fast and continuous generation of reactive oxygen species (ROSs) via iron-based advanced oxidation processes (AOPs) is significant in the environmental and biological fields. However, current AOPs assisted by co-catalysts still suffer from the poor mass/electron transfer and non-durable promotion effect, giving rise to the sluggish Fe2+/Fe3+ cycle and low dynamic concentration of Fe2+ for ROS production. Herein, we present a three-dimensional (3D) macroscale co-catalyst functionalized with MoS2 to achieve ultra-efficient Fe2+ regeneration (equilibrium Fe2+ ratio of 82.4%) and remarkable stability (more than 20 cycles) via a circulating flow-through process. Unlike the conventional batch-type reactor, experiments and computational fluid dynamics simulations demonstrate that the optimal utilization of the 3D active area under the flow-through mode, initiated by the convection-enhanced mass/charge transfer for Fe2+ reduction and then strengthened by MoS2-induced flow rotation for sufficient reactant mixing, is crucial for oxidant activation and subsequent ROS generation. Strikingly, the flow-through co-catalytic system with superwetting capabilities can even tackle the intricate oily wastewater stabilized by different surfactants without the loss of pollutant degradation efficiency. Our findings highlight an innovative co-catalyst system design to expand the applicability of AOPs based technology, especially in large-scale complex wastewater treatment.

《环境科学与工程前沿（英文）》 2015年 第9卷 第3期   页码 429-435 doi: 10.1007/s11783-014-0677-6

摘要： In the present study, the decomposition rates of carbon tetrachloride (CCl ) and 2,4-dichlorophenol (2,4-DCP) in water by the ultraviolet (UV) light irradiation alone and H O /UV were experimentally investigated. The detailed experimental studies have been conducted for examining treatment capacities of the two different ultraviolet light sources (low and medium pressure Hg arc) in H O /UV processes. The low or medium UV lamp alone resulted in a 60%–90% decomposition of 2,4-DCP while a slight addition of H O resulted in a drastic enhancement of the 2,4-DCP decomposition rate. The decomposition rate of 2,4-DCP with the medium pressure UV lamp alone was about 3–6 times greater than the low pressure UV lamp alone. In the direct photolysis of aqueous CCl , the medium pressure UV lamp had advantage over the low pressure UV lamp because the molar extinction coefficient of CCl at shorter wavelength (210–220 nm) is about 20 to 50 times higher than that at 254 nm. However, adding H O to the medium pressure UV lamp system rendered a negative oxidation rate because H O acted as a UV absorber being competitive with CCl due to negligible reaction between CCl and OH radicals. The results from the present study indicated significant influence of the photochemical properties of the target contaminants on the photochemical treatment characteristics for designing cost-effective UV-based degradation of toxic contaminants.
