Rapid socio-economic development and urbanization have resulted in serious deterioration in air-quality in many world cities, including Beijing, China. This preliminary study is the first attempt to examine the effectiveness of air pollution control regulations implemented in Beijing during 2013 - 2017 through a data-driven regulatory intervention analysis. Our proposed machine- learning model utilizes proxy data including Aerosol Optical Depth (AOD) and meteorology; it can explain 80% of the PM2.5 variability. Our preliminary results show that air pollution control regulatory measures introduced in China and Beijing have reduced PM2.5 pollution in Beijing by 23% on average.
This paper describes an all solid-state switched pulser for an air pollution control system. The proposed pulser can produce 20 kV, 500 A, 100 ns pulses at repetition rates up to 10 kHz, and it is composed of 30 series connections of power circuit card assemblies which contain paralleled MOSFETs, energy storage capacitors and pulse transformer. Higher pulse voltages and currents can easily be obtained by increasing the numbers of series and parallel connections of power circuit cards and MOSFETs, respectively. This paper places emphasis on the overvoltage and the overcurrent protections including short circuit conditions for reliable operation in real situations. Experimental results show that the proposed pulser is very efficient in air pollution control application and could be useful for other applications such as synthesis of nanosize powders and nonthermal food processing.
Indoor air pollution is causing increasing widespread attention in university now. The main source of indoor air pollutants in university was analyzed. Students' cognition of indoor air pollution and its health hazards were studied, in order to improve students' awareness of prevention and provide the basis for development of protective measures. Let 1498 students write self- administered questionnaire in university in Shenyang. The results show that: 92.5% of students know the indoor air pollution and understand the common indoor pollutants in a certain, but no sufficient attention to indoor air pollution. It is only 44.8% of the students who know must take steps to control indoor air pollution now. It is 68.2% of students who think of the best method to tackle indoor air pollution is ventilation. Finally, a few suggestions are proposed on prevention and control of indoor air pollution in university.
In this paper, we established a rating charge model of transfer tax (RCTT) to solve transboundary air pollution control problem of China. Firstly, by using the bi-level nonlinear programming model. In this model, the leader is China's central government and the followers consist of China's 31 provinces. The leader aims to decrease the nation's total pollutant control costs, whereas each province attempts to minimize its pollution control costs by balancing its own pollutant reduction cost with transfer tax to or from other provinces, in the context of a transfer tax rate set by the leader. Then, we used the SO2 reduction amount of Beijing, Tianjin and Hebei province from 2003 to 2009 as an example to fit the environmental damage cost of air pollutants. Finally, the optimal solution of RCTT model was compared with Provincial Territorial Management Model based on basic data. The results showed that RCTT model not only can make the total cost of pollution control in the whole region is the lowest but also promote cooperation of each administrative region to control the transboundary air pollution.
It is an important issue that city government must pay attention to the air pollution control. A basic assumption of the viewpoint is that city government can control the air pollution theoretically depend on the actualization of some market-oriented policies such as environmental taxes, tradable permits, finance allowance for reducing pollution, etc. However, those contentions are not always available in a city competition setting in china. With the dynamic game model between the pollution enterprise and the city government being built, and the presuppositions of 'possessing the core competencies' with 'the furious competition condition' being compared, the evolvement rule of firm's and city's profitability was discovered, and some policies were put forward for air pollution control in a city competition setting in china.
Aiming at enhanced particulate matter (PM) removal of electrostatic precipitators (ESPs) in coal-fired power plants, a pulse energization power supply that generates highvoltage pulses superimposed on a high-voltage dc was designed. The integrated theories of corona discharge, particle charging, and removal were presented, and the pulse energization strategy was studied through fractional particle removal simulation. The conclusion of simulation stated that pulse energization could significantly improve particle charge with a maximum enhancement at a particle diameter of 20 μm, while the fractional particle removal efficiency shows a different distribution that removal of particles less than 2.5 μm had the most significant enhancement. Based on the design and simulations, a full-scale comparative operation study testified the potential of dc + pulse energization to enhance particle removal with a limited power consumption increase. Pulse energization was applied to different industrial ESPs with various design and operation parameters and shown multicondition adaptability in PM removal enhancement, with the emission reduction ranging from 45.48% to 58.00% and outlet concentration from 8.60 to 47.48 mg/Nm3, proving it a convenient and economical method in the performance boost of industrial ESPs.
Although air pollution control technology was very mature, air pollution situation in China was still serious. Air pollution control technology was not a single problem but a complex economic problem. Air pollution control audit has become a major work of our government audit office. But audit practices in air pollution control projects still focus on the use of funds-based. Control effects of air pollution were difficult to evaluation comprehensively. In this paper, the spread diffusion form of pollution, the concentration distribution scope of pollution and air pollution diffusion were analyzed to build the source model, the ground model of the biggest pollution, pollution migration patterns and other air pollution control trajectory model. By comparing three models on the audit object, scope economic, efficiency, effectiveness, indicators, risk and audit opinions, pollution migration trajectory model was the most comprehensive, objective and accurate audit model. It offered certain reference on carrying out the regional air pollution control audit.

Successful introduction of pulsed corona for industrial purposes very much depends on the reliability of high-voltage and pulsed power technology and on the efficiency of energy transfer. In addition, it is of the utmost importance that adequate electromagnetic compatibility (EMC) is achieved between the high-voltage pulse source and the surrounding equipment. Pulsed corona is generated in a pilot unit that produces narrow 50 MW pulses at 1000 pps (net average corona power 1.5 kW). The pilot unit can run continuously for use in industrial applications such as cleaning of gases (100 m/sup 3//h) containing NO or volatile organic compounds (VOCs) or fluids (e.g., waste water). Simultaneous removal of NO and ethylene to obtain clean CO/sub 2/ from the exhaust of a combustion engine was tested at an industrial site. Various chemical processes, such as removal of toluene or styrene from an airflow are tested in the laboratory. We developed a model to analyze the conversion of these pollutants. To examine the discharges in the reactor we use current, voltage, and E-field sensors as well as a fast charge-coupled device (CCD) camera. Detailed energy input measurements are compared with CCD movies to investigate the efficiency of different streamer phases. EMC techniques incorporated in the pilot unit are based on the successful concept of constructing a low transfer impedance between common mode currents induced by pulsed power and differential mode voltages in signal lines and external main lines.
An atmospheric micro plasma is generated in micro gap electrodes with a dielectric barrier. Discharge voltage is only around 1 kV, although the electrode gap is less than 100 mum. Ozone is generated through the micro plasma electrode, which removes indoor air pollutants such as formaldehyde and nitric oxides. By making the micro gap between dielectric barrier electrodes smaller, a higher ozone concentration could be obtained.
