杭州水产养殖污染的现状和对策
|
摘要
首先分析了养殖水体对环境的污染及危害,以及杭州水产养殖的污染现状,并对杭州市各地区污染物排放情况进行了系统的调查,最后探讨了相关的水产养殖污染防治对策。结果表明,杭州市各地区的水产养殖每年向水体排放氨氮11 720.18 kg,COD 561 163.95kg,铜209 791.61 g,锌614 253.78 g,总氮76 644.88 kg,总磷15 960.16 kg,水产养殖污染对河道水环境造成了直接的威胁。
The pollution and the harm of the water pollution to the environment,and the current situation of the pollution in Hangzhou were analyzed. Pollutant discharge of Hangzhou City were systematically investigated,and then countermeasures for the prevention and control of the pollution were discussed. The results showed that discharge of ammonia nitrogen was 11 720. 18 kg per year in aquaculture of Hangzhou City,and 561 163. 95 kg of COD emissions,copper emissions 209 791. 61 g,614 253. 78 g of zinc emissions,total nitrogen emissions 76 644. 88 kg,total phosphorus emissions 15 960. 16 kg. The pollution of aquaculture had caused a direct threat to the water environment.
