Assessment on the implementation of water pollutant discharge standard in Qingyi River Basin
The evaluation of pollutant discharge standards is an important link in the implementation cycle of the discharge standards,but the practical exploration of the evaluation of the implementation effect of basin water pollutant discharge standards in China is relatively lacking.Based on existed specifications and guidelines,the water pollutant discharge standard evaluation system was established for"Discharge standard of water pollutants in Qinghe River Basin"(DB 41/790-2013).The implementation of the standard was also evaluated in Qinghe River Basin.The results showed that the control of key pollutants in the standard was at a medium level,and there was a slight lack of fine control in the subregion.Benefited from the implementation of the standard,the emission mode of pollution sources had been optimized.The reduction of pollutant emissions and optimization of industrial structure and elimination of backward production capacity were also promoted by the implementation of the standard.The water environment of the basin had been greatly improved,but there were also problems such as lack of pertinence and restraint to the industrial pollution control.
