Tianjin is the hottest city to implement different

Introduction: the current pollutant emission concentration of the power plant is less than half of the specified emission standard, so the gain is not worth the loss. Therefore, you can enjoy a 40% discount when you pay the pollutant discharge fee

sulfur dioxide, nitrogen oxides, smoke and dust produced by industrial enterprises burning coal are important factors causing frequent smog in Beijing Tianjin Hebei region. In recent years, Tianjin has used economic leverage to significantly raise the collection standard of sewage charges and implement differentiated charges for enterprises' sewage discharge, so as to promote enterprises, especially large-scale coal-fired power plants, to control pollution and reduce emissions, which has achieved positive results

from July 2014, Tianjin began to implement a new sewage charge standard: the sewage charge standard for sulfur dioxide, nitrogen oxide, chemical oxygen demand, ammonia nitrogen and other four pollutants was increased from the original average of about 0.82 yuan per kilogram to 7.82 yuan, an increase of nearly 10 times

Chen Jishan, the environmental protection director of Dagang Power Plant, made a mistake by raising the pollution charge by such a large margin. He calculated an account. Referring to the total pollutant emissions of 1800 tons of sulfur dioxide and 9600 tons of nitrogen oxide from the four generating units of the power plant in 2013, if the new charging method is adopted, the enterprise will need to spend more than 20million yuan only to pay the sewage charge every year

however, this is not the case. Dagang Power Plant paid only 3.1 million yuan of sewage charges in 2015, about 17million yuan less than expected

the pollution discharge fee has increased nearly 10 times. Why does the pollution discharge fee paid by enterprises not increase, but also decrease? It turned out that this scheme of increasing the price of sewage charges in Tianjin has the nature of step pricing and rewarding diligence and punishing laziness: for those enterprises whose pollutant emission concentration is lower than the specified emission standard, they can enjoy a charge discount ranging from 40% to 10%; If the pollutant discharge concentration exceeds the specified discharge standard, the sewage charge shall be calculated and charged according to the charging standard plus one time

according to this regulation, the lower the percentage of pollutant emission concentration in the specified emission standard, the lower the cost paid by the enterprise. When it is lower than 50% of the specified standard, the enterprise can enjoy a 40% discount of the charging standard by setting a stepless experimental speed for the high-precision imported speed regulating motor

wenwurui, director of Tianjin Environmental Protection Bureau, said that in the past, many enterprises preferred to pay more pollution charges due to low pollution charges, which fell by 43.51% year-on-year; Excluding exchange losses, the net profit per ton is about 328 yuan (5.2% 2.53%), and it is also unwilling to invest in environmental protection facilities. Now this situation has changed. Many enterprises have adopted new technologies and equipment to reduce pollutant emissions

so for enterprises, what can we do to reduce the pollution discharge fee? A good way is to try to reduce pollutant emissions. Chen Jishan said that since 2013, Dagang Power Plant has invested 620million yuan in the operation of four generating units. In the process of operation, it also needs to start from the details to carry out environmental protection and energy-saving transformation of desulfurization, denitration and dust removal systems. Through the transformation, the emission concentrations of sulfur dioxide, nitrogen oxide and soot emitted by the unit have been reduced from the original 20, 350 and 15 mg/m3 to the current 15, 30 and 5 mg/m3 respectively

the current pollutant emission concentration of the power plant is less than half of the specified emission standard, so you can enjoy a 40% discount when paying the sewage charge. Compared with 2013, we can reduce sulfur dioxide emissions by 1500 tons, nitrogen oxides by nearly 9000 tons and soot by more than 800 tons every year. Chen Jishan said

the high standard and differentiated sewage charge standard not only brings economic benefits into play, but also produces environmental benefits gradually. According to the monitoring data of Tianjin Environmental Protection Bureau, in 2015, the number of days of air quality reaching the standard in Tianjin was 220, an increase of 45 days year-on-year, and the proportion of days reaching the standard exceeded 60%
