摘要
对渭河宝鸡段各排污口的排放量及污染物进行分析,并用两种方法计算水环境容量及削减量,由此可以对污水的排放量进行控制.以便对下游的影响达到最小.最后对各监测断面在不同时期、不同流量下的CODMn和氨氮浓度进行了统计分析.得知随着时间的推移,它们的浓度呈下降趋势.
It is analysed that drainage quantity and pollutant of every drainage sewage hole of Weihe BaoJi segment. Calculated water environment capacity and abridged capacity using two method,We can control drainage quantity of wastewater according to it.So it is least that influence upon downriver.At last,CODMn and annonia nitrogen concentration of every monitor point are statistic analysis with differ period and differ runoff.We knowthat their concentrations get small with the time processing.
