Application of permanganate in the oxidation of micropollutants: a mini review

Xiaohong GUAN, Di HE, Jun MA, Guanghao CHEN

《环境科学与工程前沿（英文）》 2010年 第4卷 第4期   页码 405-413 doi: 10.1007/s11783-010-0252-8

摘要： As a green oxidant, permanganate has received considerable attention for the removal of micropollutants in drinking water treatment. To provide a better understanding of the oxidation of organic micropollutants with permanganate, the oxidation kinetics of 32 micropollutants were compiled. The pollutants include algal toxins, endocrine disrupting chemicals (EDCs), and pharmaceuticals. The oxidation kinetics of micropollutants by permanganate were found to be first order with respect to both contaminant and permanganate concentrations from which second-order rate constants ( ″) were obtained. Permanganate oxidized the heterocyclic aromatics with vinyl moiety (i.e., microcystins, carbamazepine, and dichlorvos) by the addition of double bonds. For the polycyclic aromatic hydrocarbons (PAHs) with alkyl groups, permanganate attacked the benzylic C-H through abstraction of hydrogen. The mechanism for the oxidation of phenolic EDCs by permanganate was a single electron transfer and aromatic ring cleavage. The presence of background matrices could enhance the oxidation of some phenolic EDCs by permanganate, including phenol, chlorinated phenols, bisphenol A, and trichlosan. The toxicity of dichlorvos solution increased after permanganate oxidation, and the estrogenic activity of bisphnol A/estrone increased significantly at the beginning of permanganate oxidation. Therefore, the toxicity of degradation products or intermediates should be determined in the permanganate oxidation processes to better evaluate the applicability of permanganate. The influence of background ions on the permanganate oxidation process is far from clear and should be elucidated in the future studies to better predict the performance of permanganate oxidation of micropollutants. Moreover, methods should be employed to catalyze the permanganate oxidation process to achieve better removal of micropollutants.

SPATIOTEMPORAL VARIATION OF WATER QUALITY AND ALGAL BIOMASS IN ERHAI LAKE AND ITS ENVIRONMENTAL MANAGEMENT

《农业科学与工程前沿（英文）》 2023年 第10卷 第4期   页码 566-578 doi: 10.15302/J-FASE-2023520

摘要：

Elucidating the spatiotemporal pattern of water quality and algal biomass is crucial for accurately tracing pollution sources and reducing the risk of algal blooms in lake systems. This study analyzed the spatiotemporal variability of water quality and algal biomass in Erhai Lake from 1994 to 2021 using water quality index (WQI), Mann-Kendall test and Sen’s slope combined methods. The potential causes of water quality deterioration and algal biomass dynamics were also elucidated. The results showed that the historical changes in the water environment of Erhai Lake mainly had three stages: satisfactory (1994‒2001), deteriorating (2002‒2010) and improving (2011‒2021). The changes in water quality and algal biomass were primarily affected by total nitrogen, total phosphorus and chemical oxygen demand in different stages. The water environment of Erhai Lake is currently improving significantly, starting in the southern area that is furthest from the sources of agricultural pollution, especially in summer and autumn. This is attributed to the implementation of control measures resulting in lower pollutant loads at particular times and places. Therefore, it is necessary to continue to promote standardized livestock farming, to strengthen rural wastewater collection and to investigate measures such as the interruption of the endogenous cycle.

WEI Qun, HU Zhiquan, LI Genbao, XIAO Bo, SUN Hao, TAO Meiping

《环境科学与工程前沿（英文）》 2008年 第2卷 第4期   页码 446-451 doi: 10.1007/s11783-008-0064-2

摘要： Algal biofilm technology is a new and advanced wastewater treatment method. Experimental study on removing nitrogen and phosphorus from simulated wastewater using algal biofilm under the continuous light of 3500 Lux in the batch and continuous systems was carried out in this paper to assess the performance of algal biofilm in removing nutrients. The results showed that the effect of removing nitrogen and phosphorus by algal biofilm was remarkable in the batch system. The removal efficiencies of total phosphorus (TP), total nitrogen (TN), ammonia-nitrogen (NH-N), and chemical oxygen demand (COD) reached 98.17%, 86.58%, 91.88%, and 97.11%, respectively. In the continuous system, hydraulic retention time (HRT) of 4 days was adopted; the effects of removing TP, TN, NH-N, and COD by algal biofilm were very stable. During a run of 24 days, the removal efficiencies of TP, TN, NH-N, and COD reached 95.38%, 83.93%, 82.38%, and 92.31%, respectively. This study demonstrates the feasibility of removing nitrogen and phosphorus from simulated wastewater using algal biofilm.

《环境科学与工程前沿（英文）》 2008年 第2卷 第4期   页码 421-438 doi: 10.1007/s11783-008-0070-4

摘要： Algal-bloom control is an important issue for water environment protection as it induces several negative impacts on the lives of aquatic organisms, aquaculture, landscaping, and human health. The development of an environment-friendly, cost-effective, and convenient alternative for controlling algal bloom has gained much concern. Using the allelopathy of aquatic macrophytes as a novel and safe method for algal-bloom control is a promising alternative. This paper reviews the development and potential application about allelopathy of aquatic plants on algae, including the allelopathic research history, the potential research problems, the research methodology, and the reported aquatic macrophytes and their inhibitory allelochemicals. Potential modes of inhibition action of allelochemicals on algae, possible ways for application, and future development directions of research on algal-bloom control by aquatic macrophytes were also presented.

Formation of disinfection byproducts from accumulated soluble products of oleaginous microalga after chlorination

Yu Liu, Qiao Zhang, Yu Hong

《环境科学与工程前沿（英文）》 2017年 第11卷 第6期 doi: 10.1007/s11783-017-0938-2

摘要： When microalgae are simultaneously applied for wastewater treatment and lipid production, soluble algal products (SAP) should be paid much attention, as they are important precursors for formation of disinfection byproducts (DBPs), which have potential risks for human health. sp. HQ is an oleaginous microalga that can generate SAP during growth, especially in the exponential phase. This study investigated the contribution of SAP from sp. HQ to DBP formation after chlorination. The predominant DBP precursors from SAP were identified with the 3D excitation-emission matrix fluorescence. After chlorination, a significant reduction was observed in the fluorescence intensity of five specific fluorescence regions, particularly aromatic proteins and soluble microbial by-product-like regions, accompanied with slight shifting of the peak. The produced DBPs were demonstrated to include trihalomethanes and haloacetic acids. As the algal cultivation time was extended in wastewater, the accumulated SAP strengthened the formation of DBPs. The trend for DBP formation was as follows: chloroform>dichloroacetic acid>trichloroacetic acid.

《农业科学与工程前沿（英文）》 2015年 第2卷 第3期   页码 266-275 doi: 10.15302/J-FASE-2015064

摘要： Algal blooms have become a worldwide environmental concern due to water eutrophication. Dianchi Lake in Yunnan Province, China is suffering from severe eutrophication and is listed in the Three Important Lakes Restoration Act of China. Hydrothermal liquefaction allows a promising and direct conversion of algal biomass into biocrude oil. In this study, algal samples were collected from Dianchi Lake after a separation procedure including dissolved air flotation with polyaluminum chloride and centrifugation during four months, April, June, August and October. The algal biochemical components varied over the period; lipids from 0.7% to 2.1% ash-free dry weight (afdw), protein from 20.9% to 33.4% afdw and ash from 36.6% to 45.2% dry weight. The algae in June had the highest lipid and protein concentrations, leading to a maximum biocrude oil yield of 24.3% afdw. Biodiversity analysis using pyrosequencing revealed different distributions of microbial communities, specifically in April (89.0%), June (63.7%) and August (84.0%), and in April (2.2%), June (12.0%) and August (1.0%). This study demonstrated remarkable temporal changes in the biochemical composition and biodiversity of algae harvested from Dianchi Lake and changes in biocrude oil production potential.

Interactions between nano-TiO

《化学科学与工程前沿（英文）》 2015年 第9卷 第2期   页码 242-257 doi: 10.1007/s11705-015-1513-7

摘要： Nano-sized titanium dioxide (nano-TiO ) has wide industrial applications and therefore considerable chances of exposure are created for human beings and ecosystems. To better understand the interactions between nano-TiO and aquatic organisms, we first studied TiO uptake by algae exemplified by were exposed to nano-TiO in a series of concentrations and at various pH. TiO uptake was quantified using a sedimentation curve analysis technique. After exposure of algae to TiO , the variation of zeta potential was measured and the morphology of algae-TiO aggregate was observed with scanning electron microscopy and the optical microscopy. The steady-state TiO uptake was found to be pH-dependent and the isotherms can be described well by Freundlich model. TiO deposited on algal surfaces causes the shift of pH of TiO -covered algae from that of algae toward that of TiO . The attraction between TiO -covered algal cells induces the agglomeration of algae and TiO and thus the formation of algae-TiO aggregates in the size of 12 to 50 μm. The 2-D fractal dimension of the aggregates is pH-dependent and ranges from 1.31 to 1.67. The theoretical analysis of the Gibbs energy of interaction indicates that both TiO uptake by algae and the formation of algae-TiO aggregate are influenced by the interaction between TiO particles.

Macrozoobenthic assemblages in relation to environments of the Yangtze-isolated lakes

Baozhu PAN, Haijun WANG, Hongzhu WANG, Zhaoyin WANG

《环境科学与工程前沿（英文）》 2012年 第6卷 第2期   页码 246-254 doi: 10.1007/s11783-011-0381-8

摘要： Eutrophication can shift lakes from a clear, macrophyte-dominated state to a turbid, algae-dominated state, and different habitat condition supports different fauna. Macrozoobenthos are good indicators of water environment, and studies on macrozoobenthic assemblage characteristics can help us to know which state a lake is in, thus provide the basis for its eutrophication control. In this study, a systematic investigation on macrozoobenthos was conducted in 17 Yangtze-isolated lakes to explore the macroecological laws of macrozoobenthic assemblages. Detrended correspondence analysis (DCA) revealed that variance of benthic assemblage structure occurred in two types of lakes. In macrophytic lakes, altogether 51?taxa of macrozoobenthos were identified. The average density and biomass of total macrozoobenthos were 2231?individuals·m and 1.69 g dry weight·m , respectively. Macrozoobenthic assemblage was characterized by dominance of scrapers (i.e. gastropods). In algal lakes, altogether 20 taxa of macrozoobenthos were identified. The average density and biomass of total macrozoobenthos were 2814 individuals·m and 1.38 g dry weight·m , respectively. Macrozoobenthic assemblage was characterized by dominance of collector-gatherers (i.e. oligochaetes). Wet biomass of submersed macrophytes ( ) and phytoplankton chlorophyll concentration ( ) were demonstrated as the key factor structuring macrozoobenthic assemblages in macrophytic and algal lakes, respectively.

Qiao ZHANG,Yu HONG

《环境科学与工程前沿（英文）》 2014年 第8卷 第5期   页码 703-709 doi: 10.1007/s11783-014-0649-x

摘要： This study compared the growth and lipid accumulation properties of two oleaginous microalgae, namely, sp. LX1 and sp. HQ, under different nutrient conditions. Both algal species obtained the highest biomass, lipid content and lipid yield under low-nutrient conditions (mBG11 medium). The biomass, lipid content and lipid yield of sp. LX1 were 0.42 g·L , 22.5% and 93.8 mg·L , respectively. These values were relatively higher than those of sp. HQ (0.30 g·L , 17.1% and 51.3 mg·L , respectively). These algae were then cultivated in an SE medium that contained more nutrients; as a result, the biomass and lipid yield of sp. LX1 reduced more significantly than those of sp. HQ. Opposite results were observed in lipid and triacylglycerols (TAGs) contents. The cell sizes of both algal species under low-nutrient conditions were larger than those under high-nutrient conditions. sp. HQ cells did not aggregate, but sp. LX1 cells flocculated easily, particularly under low-nutrient conditions. In summary, low-nutrient conditions favour the growth and lipid production of both algae, but sp. LX1 outperforms sp. HQ.

摘要：

金黄色葡萄球菌（S. aureus）是一种常见的人类病原体，它可以引发严重的侵袭性感染，如菌血症、败血症和心内膜炎，具有较高的发病率和死亡率。然而由于细菌的抗生素耐药性增强，如耐甲氧西林金黄色葡萄球菌（MRSA），加剧了此类细菌的发病率和死亡率。金黄色葡萄球菌的发病机制是由毒素的分泌推动的，如膜损伤孔α毒素，它有不同的细胞靶点，包括上皮细胞、内皮细胞、白细胞和血小板。本文采用人体血小板膜包覆纳米颗粒（PNP）作为一种仿生诱饵策略，来中和金黄色葡萄球菌的毒素，并维持宿主细胞的防御功能。血小板膜包覆纳米颗粒保护血小板免受由金黄色葡萄球菌毒素带来的损伤，维持血小板活化和杀菌活性。血小板膜包覆纳米颗粒也同样保护巨噬细胞免受由金黄色葡萄球菌毒素带来的损伤，支持巨噬细胞进行氧化迸发、产生一氧化氮和维持其杀菌活性，并减少耐甲氧西林金黄色葡萄球菌诱导的中性粒细胞胞外杀菌网络。在感染系统性耐甲氧西林金黄色葡萄球菌的小鼠模型中，血小板膜包覆纳米颗粒制剂减少了血液中的细菌数量并防止小鼠发生死亡。总之，目前的研究结果证明了血小板膜包覆纳米颗粒的治疗优点，如中和毒素、保护细胞和增加宿主对侵袭性金黄色葡萄球菌感染的抵抗力。
