In this article, it designs an escape system for vehicles in water crashes. The structure mainly contains sensors, control organs and actuating mechanism for both doors and windows. Sensors judge whether the vehicle falls into water or is in the falling process. The actuating mechanism accepts the signal delivered by the control organs, then open the electronic central lock on doors and meanwhile lower the window. The water escape system is able to anticipate drowning situations for vehicles and controls both doors and windows in such an emergency. Under the premise of doors staying in an undamaged state, it is for sure that people in the vehicle can open the door while drowning in the water and safely escape.

R. China Shenzhen Long Cheng High-tech Environmental protections Co. Ltd. Shenzhen Guangdong 518063

Because of the large content of organic matter as well as nitrogen, the competition between phosphate accumulating organisms (PAOs) and glycogen accumulating organisms (GAOs) was serious in wastewater. This phenomenon led to biological phosphate removal in a SBBR with micro-bubble technology was not quite effective. Meanwhile, it can be concluded that the high dissolved oxygen (DO), ammonia nitrogen(NH4+), sludge solubilization affect the biological phosphate removal seriously. This paper was aimed to provide some information's to improve the phosphate removal in the next step.

A Demand Response Scheme for Wind Integrated Power system Based on Mechanism Design Theory

引用

IOP Conference Series: Materials Science and Engineering 2018年第1期366卷

作者： Xueliang Li Donglei Sun Yumin Zhang Xueshan Han Mingqiang Wang Si Yang Wenbo Li Xin Wei Economic & Technology Research Institute of State Grid Shandong Electric Power Company Jinan China Key Laboratory of Power System Intelligent Dispatch and Control of Ministry of Education Shandong University Jinan 250061 China State Grid Shandong Electric Power Research Institute Jinan China

The increasing integration of high penetration of wind power into power systems have created great challenges for stable operation of the power system. It is important to design a reasonable demand response scheme (DRS) to make decision the optimal load relief, specially, for the wind power suppliers (WPS) and their customers (WPSC). Therefore, this paper proposes a demand response scheme for wind integrated power system based on mechanism design theory. Firstly, we derive the outage cost function and incentive function modeled by the two variables: the customers' type parameter and the location value. Secondly, incorporate customers' type parameter and locational flexibility into the DRS, and based on game theory, a demand response scheme with incentive compatible constraint and participation constraint is designed to maximize the benefit both the wind power suppliers and their customers. The implication of demand response scheme is to design an incentive structure that encourages customers to sign up for the right scheme and reveal their true value of load reduction. Finally, the eight-bus system example can demonstrate the effectiveness of the proposed method.

Current Status and Future Perspective of Recycling Copper by Hydrometallurgy from Waste Printed Circuit Boards

引用

Procedia Environmental Sciences 2016年 31卷 162-170页

作者： Yan Xu Jinhui Li Lili Liu State Key Joint Laboratory ofEnvironment Simulation andPollution Control School of Environment Tsinghua University Beijing 100084 China

The current replacement of electronic products is speeding up, resulting in a growing number of e-waste. Electronic waste, especially waste print circuit boards contain large amounts of copper, which not only bring greater ecological threat, but also cause a serious waste of copper resources. Therefore, the study on clean, effective copper leaching technology has a very important practical significance to reduce environmental hazards of waste print circuit board and resources recycling. Hydrometallurgical is a better technology for recycling copper from waste print circuit boards. In this article, hydrometallurgical copper recovery system is divided into four categories: acid leaching, ammonia - ammonium leaching, chloride leaching, as well as other ways of leaching. The advantages and disadvantages of leaching of copper system are analyzed in the process of copper resource utilization. Studies abound on recycling copper from copper-containing waste with citric acid and other complexing agents as the leaching reagent, but studies on recycling copper from waste print circuit boards are rarely reported, which can be used for reference. The trends of the research are using environmentally friendly reagent as leaching agent, selecting the appropriate leaching solution at a certain temperature and pressure and optimizing the subsequent separation procedure. Recycling of waste gas and waste leachate generated in the hydrometallurgical processcan further reduce chemical costs and meet increasingly exacting environmental requirements.

Effect of gamma-ray irradiation at low doses on the performance of PES ultrafiltration membrane

引用

Radiation Physics and Chemistry 2016年 127卷 127-132页

作者： Zhang, Xue Niu, Lixia Li, Fuzhi Yu, Suping Zhao, Xuan Hu, Hongying Collaborative Innovation Center for Advanced Nuclear Energy Technology Institute of Nuclear and New Energy Technology Tsinghua University Beijing 100084 China State Environmental Protection Key Laboratory of Microorganism Application and Risk Control (MARC) Graduate School at Shenzhen Tsinghua University Shenzhen 518055 China Environmental Simulation and Pollution Control State Key Joint Laboratory School of Environment Tsinghua University Beijing 100084 China

The influence of gamma irradiation on the performance of polyether sulfone (PES) ultrafiltration (UF) membrane was investigated at low absorbed doses (0-75 kGy) using a cobalt source. The performance of the UF membranes was tested using low level radioactive wastewater (LLRW) containing three types of surfactants (anionic, cationic and nonionic surfactants). The physical and chemical properties of membrane surface were analyzed, and relationships between these properties and separation performance and fouling characteristics were determined. At 10-75 kGy irradiation, there were no significant changes observed in the membrane surface roughness or polymer functional groups, however the contact angle decreased sharply from 92° to ca. 70° at irradiation levels as low as 10 kGy. When membranes were exposed to the surfactant-containing LLRW, the flux decreased more sharply for higher dosed irradiated membranes, while flux in virgin membranes increased during the filtration processes. The study highlights that fouling properties of membrane may be changed due to the changes of surface hydrophilicity at low dose irradiation, while other surface properties and retentions remain stable. Therefore, a membrane fouling test with real or simulated wastewater is recommended to fully evaluate the membrane irradiation resistance. © 2016 Elsevier Ltd.

Waste Cathode Rays Tube: An Assessment of Global Demand for Processing

引用

Procedia Environmental Sciences 2016年 31卷 465-474页

作者： Narendra Singh Jiecong Wang Jinhui Li State Key Joint Laboratory of Environment Simulation and Pollution Control School of Environment Tsinghua University Beijing 100084 China

The management of used Cathode rays tube (CRT) devices is a major problem worldwide due to rapid uptake of the technology and early obsolescence of CRT devices, which is considered an environment hazard if disposed improperly. Previously, their production has grown in step with computer and television demand but later on with rapid technological change; TVs and computer screens has been replaced by new products such as Liquid Crystal Displays (LCDs) and Plasma Display Panel (PDPs). This change creates a large volume of waste stream of obsolete CRTs waste in developed countries and developing countries will become major CRTs waste producers in the forthcoming decades. This article provides a concise overview of world's current CRTs waste scenario, namely magnitude of the demand and processing, current disposal and recycling operations.

Procedia Environmental Sciences 2016年 31卷 867-872页

作者： Lingyu Sun Xianlai Zeng Jinhui Li State Key Joint Laboratory of Environment Simulation and Pollution Control School of Environment Tsinghua University Beijing 10084 China

With the rapid development of science and technology especially in the ICT industry all over the world, WEEE has been considered to be one of the most important waste streams during the last decade and will continue to be so in the future. WEEE contains valuable metals as well as potential environmental contaminants so recycling E-waste is an indirect way to reuse valuable resources. In case that it is simple to dismantle the machines and almost all the E-waste consists components like PCBs and CRTs, this paper puts emphasis on the processes of dismantling and recovering resources from PCBs and CRTs as an example for their widely usage. Universal recycling processes for PCBs and CRTs are introduced briefly and pollutants released during the processes are dust and waste water mainly. Measures are proposed to control the pollution, for instance, the shredder and grinders could be isolated during the physical process and it is suggested that personal protective devices such as masks are used to reduce the exposure level to heavy metals. Secondary pollution during the recycling process is inevitable, Thus cleaner technology is urgent to come into service. Although recycling may remove some contaminants, large amounts which are difficult to disposed ought to be concentrated in landfills.

In this paper, FeO-MnO/reduced graphene oxide (RGO) hybrid was synthesized through polyol process and impregnation method and used as heterogeneous Fenton-like catalyst for degradation of sulfamethazine (SMT) in aqueous solution. The hybrid catalyst had higher catalytic efficiency compared with FeO-MnO and MnO as catalyst for degradation of SMT The effects of pH value, HO concentration, catalyst dosage, initial SMT concentration and temperature on SMT degradation were investigated. The removal efficiency of SMT was about 98% at following optimal conditions: pH=3, T=35°C, FeO/MnO-RGO composites=0.5g/L, HO=6mM. The inhibitor experiments indicated that the main active species was hydroxyl radicals (·OH) on catalyst surface. At last, the possible catalytic mechanism was proposed.
