摘要
为了解决水产养殖尾水环境负效应大的问题,根据养殖尾水特征,设计了机械结合植物净化系统。结果表明,该净化系统能够有效改善水体严重富营养化,降低水体中悬浮物、生物需氧量、化学需氧量、亚硝酸盐氮等的含量,经处理净化后尾水可以实现循环利用,具有显著的生态环境效益。
In order to solve the problem of negative environmental effect, the purification system of machine and plants was designed according to the characteristics of culture waste water. The results showed that the new system could effectively improve the eutrophication of water system, reduce the contents of suspended substance, biological oxygen demand（ BOD）, chemical oxygen demand（COD） , nitrite nitrogen and so on in water system. And the waste water could be recycled after purification and it had significant ecological benefits.
