Emerging contaminant control: From science to action

《环境科学与工程前沿（英文）》 2022年 第16卷 第6期 doi: 10.1007/s11783-022-1559-y

摘要： Since the concept of emerging contaminants (ECs) was first proposed in 2001, the global scientific research of ECs has developed rapidly. In the past decades, great progress has been achieved in the scientific research of ECs in China, including the establishment of EC analysis method system, the evaluation of the pollution status, pollution characteristics and environmental risk of ECs in typical regions of China, and establishment of EC control technology system. Continuous progress in scientific research of ECs promoted China’s action on EC control. It is planned that the environmental risk of ECs will be generally controlled by 2035 in China. Priority ECs should be screened for environmental management. Although great efforts have been made, the EC control in China still faces tremendous challenges. It is necessary to bridge the gap between scientific research and decision-making management. Based on the science and technology study, various measures such as engineering, policy management and public participation should be combinedly adopted for EC control.

Improved resilience measure for component recovery priority in power grids

《工程管理前沿（英文）》 2021年 第8卷 第4期   页码 545-556 doi: 10.1007/s42524-021-0161-5

摘要： Given the complexity of power grids, the failure of any component may cause large-scale economic losses. Consequently, the quick recovery of power grids after disasters has become a new research direction. Considering the severity of power grid disasters, an improved power grid resilience measure and its corresponding importance measures are proposed. The recovery priority of failed components after a disaster is determined according to the influence of the failed components on the power grid resilience. Finally, based on the data from the 2019 Power Yearbook of each city in Shandong Province, China, the power grid resilience after a disaster is analyzed for two situations, namely, partial components failure and failure of all components. Result shows that the recovery priorities of components with different importance measures vary. The resilience evaluations under different repair conditions prove the feasibility of the proposed method.

仲蒙蒙, 王铁龙, 赵文星, 黄俊, 王斌, Lee Blaney, 卜庆伟, 余刚

《工程（英文）》 2022年 第11卷 第4期   页码 111-125 doi: 10.1016/j.eng.2020.12.023

摘要：

近20 年来，新兴有机污染物（EOC）在水环境中的污染现状和潜在危害引起了人们的广泛关注。由于EOC的种类多、数量大，监测项目、治理措施和法律法规应重点关注对生态系统和人体健康产生重要影响的污染物。本文提出了一种基于危害指数和暴露指数的多标准筛选方法，用于对我国地表水检出的405 种未管控的新兴污染物进行优先筛选。对污染物的危害效应、暴露潜力、生态风险和人体健康风险进行定量分析和初步筛选。危害指数为污染物持久性、生物累积性、生态毒性和人体健康危害的综合效应。同样，暴露指数为检出浓度和检出频率的综合函数。根据危害指数和暴露指数标准化值的乘积，对通过初步筛选的123 种污染物进行优先指数排序。根据排序结果，11 种污染物被列为最高优先等级，36 种污染物被列为高优先等级。通过比较优先指数与暴露指数、危害指数、生态风险、人体健康风险的排序结果，发现优先指数可以有效地整合单个指标的排序结果。根据暴露数据和危害数据的可获得性，划分了4 种不确定类别，并针对4 种不确定类别提出不同的应对措施：①对不确定类别1 中的污染物进行常规监测，制定环境质量标准和管控策略；②对不确定类别2 中的污染物增加环境监测项目；③不对确定类别3 中的污染物增加危害评估；④对不确定类别4 中的污染物增加环境监测和危害评估。总体上，本文提出了我国地表水中应优先控制的19 种新兴污染物名录建议，该名录为我国地表水中EOC的监测、控制、评价和管理提供了必要的信息。

Optimization of multi-objective integrated process planning and scheduling problem using a priority based

Muhammad Farhan AUSAF,Liang GAO,Xinyu LI

《机械工程前沿（英文）》 2015年 第10卷 第4期   页码 392-404 doi: 10.1007/s11465-015-0353-y

摘要：

For increasing the overall performance of modern manufacturing systems, effective integration of process planning and scheduling functions has been an important area of consideration among researchers. Owing to the complexity of handling process planning and scheduling simultaneously, most of the research work has been limited to solving the integrated process planning and scheduling (IPPS) problem for a single objective function. As there are many conflicting objectives when dealing with process planning and scheduling, real world problems cannot be fully captured considering only a single objective for optimization. Therefore considering multi-objective IPPS (MOIPPS) problem is inevitable. Unfortunately, only a handful of research papers are available on solving MOIPPS problem. In this paper, an optimization algorithm for solving MOIPPS problem is presented. The proposed algorithm uses a set of dispatching rules coupled with priority assignment to optimize the IPPS problem for various objectives like makespan, total machine load, total tardiness, etc. A fixed sized external archive coupled with a crowding distance mechanism is used to store and maintain the non-dominated solutions. To compare the results with other algorithms, a C-matric based method has been used. Instances from four recent papers have been solved to demonstrate the effectiveness of the proposed algorithm. The experimental results show that the proposed method is an efficient approach for solving the MOIPPS problem.

Multiple Pollutants from Crop and Livestock Production in the Yangtze River: Status and Challenges NEWS & VIEWS

《农业科学与工程前沿（英文）》 2024年 第11卷 第1期   页码 134-139 doi: 10.15302/J-FASE-2023511

摘要：

The rapid increase in the proportion of cash crops and livestock production in the Yangtze River Basin has led to commensurate increases in fertilizer and pesticide inputs. Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten Agriculture Green Development (AGD). To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil-plant-water system. This paper considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and AGD. It presents prospective on theory, modeling and multi-pollutant control in the Yangtze River Basin for AGD that are of potential value for other developing regions.

《工程管理前沿（英文）》 2015年 第2卷 第4期   页码 359-363 doi: 10.15302/J-FEM-2015057

摘要： The flue gas pollutants deep-removal technology (DRT) focusing on PM removal is the prime method of further reducing pollutants emission from coal-fired power plants. In view of the four key technological challenges in developing the DRT, studies were conducted on a series of purification technologies and the DRT was developed and successfully applied in 660 MW and 1000 MW coal-fired units. This paper analyzes the application results of the demonstration project, and proposes a roadmap for the follow-up researches and optimizations.

《环境科学与工程前沿（英文）》 2012年 第6卷 第5期   页码 649-657 doi: 10.1007/s11783-012-0426-7

摘要： A stormwater wetland treating non-point source pollution (NPS) from a 64 ha agricultural watershed was monitored over a period of five months. The results indicated that pH and dissolved oxygen (DO) were increased in the wetland due to the algal growth. The highest total suspended solids (TSS) concentration was observed in the aeration pond due to the resuspension of solids, decreased in the wetland. The respective decreases in total nitrogen (TN) and total kjeldahl nitrogen (TKN) were 15.9% and 28.7% on passing through the wetland. The nitrate and ammonia were increased by 45.4% and decreased by 79.9%, respectively. These variations provided strong evidence for the existence of nitrification. The total phosphorus (TP) and phosphate had respective reductions of 52.3% and 58.2% over the wetland. The total chemical oxygen demand (TCOD) and soluble chemical oxygen demand (SCOD) were also decreased. Generally, the TN, TP and phosphate removal efficiencies were positive. These positive removal efficiencies were mainly due to microbial activities, uptake by plants, and chemical precipitation at high pH. Negative removal efficiencies can be caused by continuous rainfall activities, with short antecedent dry days (ADDs) and unstable hydraulic conditions, some other biogeochemical transformations and algal growth also being important parameters.

《工程管理前沿（英文）》 2014年 第1卷 第4期   页码 336-340 doi: 10.15302/J-FEM-2014061

摘要： In recent years, frequent haze has made PM become a public hotspot. PM control has been added to the 2012 release “ambient air quality standard.” Currently flue gas pollutant control technology does not easily remove PM . Developing Flue Gas Pollutant Deep-removal Technology (DRT) for coal-fired power plants for deep-removing pollutants such as PM , SO , SO , and heavy metals, is an urgent problem. Based on the analysis of the necessity and existing problems of developing DRT suitable for China, this study focused on PM removal technology, low NO emission of ultra supercritical boiler under all load conditions, and the adaptability of SCR working temperature. Finally, the flue gas pollutant removal system at a 2×660MW supercritical power plant was introduced, and the roadmap for developing DRT for 1,000MW ultra supercritical units was analyzed.

Immobilization of laccase on organic–inorganic nanocomposites and its application in the removal of phenolic pollutants

《化学科学与工程前沿（英文）》 2023年 第17卷 第7期   页码 867-879 doi: 10.1007/s11705-022-2277-5

摘要： Polydopamine-functionalized nanosilica was synthesized using an inexpensive and easily obtainable raw material, mild reaction conditions, and simple operation. Subsequently, a flexible spacer arm was introduced by using dialdehyde starch as a cross-linking agent to bind with laccase. A high loading amount (77.8 mg∙g‒1) and activity retention (75.5%) could be achieved under the optimum immobilization conditions. Thermodynamic parameters showed that the immobilized laccase had a lower thermal deactivation rate constant and longer half-life. The enhancement of thermodynamic parameters indicated that the immobilized laccase had better thermal stability than free laccase. The residual activity of immobilized laccase remained at about 50.0% after 30 days, which was 4.0 times that of free laccase. Immobilized laccase demonstrated excellent removal of phenolic pollutants (2,4-dichlorophenol, bisphenol A, phenol, and 4-chlorophenol) and perfect reusability with 70% removal efficiency retention for 2,4-dichlorophenol after seven cycles. These results suggested that immobilized laccase possessed great reusability, improved thermal stability, and excellent storage stability. Organic–inorganic nanomaterials have a good application prospect for laccase immobilization, and the immobilized laccase of this work may provide a practical application for the removal of phenolic pollutants.

Beta-cyclodextrin adsorbents to remove water pollutants—a commentary

《化学科学与工程前沿（英文）》 2022年 第16卷 第9期   页码 1407-1423 doi: 10.1007/s11705-022-2146-2

摘要： Beta-cyclodextrin-based adsorbent is a promising adsorbent because it has unique characteristics and able to form host-guest complexes with various organic compounds. Adsorption using beta-cyclodextrin-based adsorbent has continuously improved by various preparation strategies and crosslinking agents. This commentary aims to highlight the preparation strategies, properties, and adsorption mechanisms of beta-cyclodextrin-based adsorbents. The adsorbents can be generally classified according to the preparation methods and display high adsorption capacity especially for dyes. Particularly, composite/nanocomposite beta-cyclodextrin-based adsorbents exhibit outstanding adsorption capacity even though the surface area is lower than that of porous and magnetic beta-cyclodextrin-based adsorbents. The beta-cyclodextrin/chitosan functionalized graphene oxide hydrogel with specific surface of 17.6 m2·g–1 yields an extraordinarily maximum adsorption capacity of 1499 mg·g–1 methylene blue, while beta-cyclodextrin/chitosan modified with iron(II, III) oxide nanoparticles displays a much greater maximum adsorption capacity at 2780 mg·g–1. The hydrophobic interaction, functional groups, hydrogen bonding, and electrostatic interaction govern the adsorption to a greater capacity. Although this commentary is not exhaustive, the preparation strategies and illustrated mechanisms provide useful insights into the adsorbent–adsorbate interactions, cost-effective analysis, challenges, and future directions of beta-cyclodextrin-based adsorbents in wastewater treatment.
