污染物排放波动特征及对排污许可限值的影响
Fluctuation of Pollutant Discharge from the Enterprises and its Effects on the Discharge Permit Limits
摘要
Abstract
Pollutant discharge of the enterprises shows a distinct fluctuation due to the production cycle.It is very necessary to give different temporal discharge permit limits to improve the supervision of the polluters.On the basis of the online pollutant monitoring data of several enterprises in Tieling City,the effects of the industry characteristics and size of the enterprises on the fluctuation of different temporal pollutant discharge amount are studied by application of β value,the ratio of short-term to longterm discharge amount.The results show that β value is greatly affected by the industrial characteristics.With regard to the three industries of slaughter,coal mining and wastewater treatment plant (WWTP),the average βMDL,the ratio of daily to annual discharge amount,is 2.82,2.61 and 1.65 respectively for CODCr,and 2.9,3.49 and 2.59 for NH3-N,indicating that WWTP is more stable than the other two industries.It is also found that the β value shows greater fluctuation when the enterprise size is small,but gets more stable when it is over a certain size.Therefore,it is very important that the industry characteristics and size of the enterprises should be taken into consideration when different temporal discharge permit limits are formulated.关键词
