The Study On Control Management System For Railway Main Pollutant

At the present time, the pollution reduction has become an important mean to improve the environment quality and solve the regional environmental problems both at home and abroad. Total quantity control is a kind of macroeconomic regulation and control index, it is an indicator of pollutant emission, which turns regional environmental target into the total quantity index, and then assigned to each pollutant discharging units. At present, the total quantity control of our country is basically the target gross control, that means the allowable emission amount of pollutants under the management goal about provisions of the scope of pollution load reduction rate, hose total amount is based on the pollutant source emission and does not exceed management rules. In order to reach the environmental requirements and the Railway strive to achieve the goal of improving production without increasing pollution in the Twelfth Five Year Plan. In this paper, with the help of new thinking and facility, to predict the major pollutants emissions of the railway in2013-2015.At the same time, from the three levels of pollution source, Railway Bureau and Railway company to build management control system of main pollutants in the railway, and lay the foundation for future development of the total pollutant discharge control in railway industry. The main research content in this paper is about:1、Through the field investigation of railway transport enterprise, screening and identificating the main pollution sources and pollutants of railway industry. By organiz a pollution sources survey in railway stations and analysis the existing pollution sources treatment process, the treatment effect, the emission factors and emission rules in railway industry.2、Using SPSS analysis the concentration of pollutants emission in Beijing Railway Bureau and the Shanghai Railway Bureau in2010-2012.Th rough the frequency analysis method to determine the upper limit value of main pollutants emission in railway3、Combining with the requirement of Railway "Twelfth Five Year" development, comprehensively considering the factors of environment quality condition, pollution control, environmental capacity present situation, proposed to increase the industrial wastewater monitoring index of BOD5, LAS, cadmium, volatile phenol, Cr6+, chromium, lead, zinc, copper, mercury, chroma, turbidity, water temperature, dissolved oxygen, permanganate etc. Indicators for monitoring the sewage increase TP, LAS, chromaticity, turbidity, water temperature, dissolved oxygen, volatile phenol, BOD5, residual chlorine, total coliform and so; for the boiler waste gas monitor index increased Ringelmann blackness.4、Analysis major pollutants emissions in china railway industry in recent five years.By horizontal comparing the same annual data of each Railway Bureau and by longitudinal comparing the different annual data of one Railway Bureau.To determine the relationship between the total emissions of major pollutants of the railway and the total volume of conversion,Which to calculate the coefficient per unit conversion volume of major pollutants emission in the railway industry. Combine railroad development in" Twelfth Five Year Plan", and make prediction about railway emissions of major pollutants in this period.Analysis the difference between pollution prediction value and pollution planning value of each railway bureau in the period of "the Twelfth Five Year Plan".Thus can complete the environmental planning target of Railway in the "Twelfth Five Year"Emission coefficient of unit conversion turnover of each railway bureau reduce13%each year.
