Analysis of water quality and organism in Shaying water treatment plant

2 0 0 2年对沙营污水处理厂的水质与生物生长情况进行了分析 .出水质能达到城镇二级水处理厂的一级排放标准 ,但是塘中生物 ,如鱼、藕的生长情况并不是很好 .针对各塘中水质情况及生物生长对环境要求的不同 ,分析了影响塘中生长的原因 .并就藻类的控制 ,提出了减少滤食性鱼类的数量 ,种植耐酸碱变化的 ,温度适应范围宽的 。

Analyzed the water quality and the organismin Shaying water treatment plant in 2002.Though the effluent could meet the first class standard of second class watertreatment plant in the town,the organisms as fishes and lotus in the ponds did not grow well.According to the water quality in the ponds and the environment demands of the organisms,suggested to reduce the amount of the filter fishes and to plant the macrophyte which could grow well in the wide range of acid-alkali and temperature to control the amount of the algae in the effluent.
