摘要： 根据太湖流域(江苏省境内)不同类型污水中总氮、总磷的浓度和当前废水治理技术及接纳水体的环境质量和经济承受能力等方面的系统分析,确定了江苏省太湖流域三级保护区内各类排污单位总氮、总磷允许排放浓度,并分析了本标准与其他排放标准之间的关系。最后,对实施本标准后的太湖水质影响进行了估算研究。

Abstract: At first this paper analyses water qualities of Taihu Lake and its rivers coming in and going out, and makes some statistics about nitrogen and phosphorus sources at the upper reaches and long the shores of Taihu valley in Jiangsu Province. Secondly, it calculates maximum permitted loads for total nitrogen and total phosphorus by a lake model which has been tested to be effective. Thirdly, according to the concentrations of total nitrogen and total phosphorus in some wastewater, present techniques of wastewater treatment, protection target for Taihu water body and economic condition etc. it puts forward some main technical parameters for determining nitrogen and phosphorus emission standards for domestic wastewater which is a principal contributor to nutritional salts, and draws up the emission standards of total nitrogen and total phosphorus applied to different pollution sources, which are classified into three scales corresponding to three protection districts at Taihu valley in Jiangsu Province. Then it discusses the relationship between the standard and other emission standards. Finally, the effect on water quality from the standard enforcement is also estimated.
