摘 要：
通过对养殖池排出污水经过弧形筛前后几个重要水质指标(溶解氧、pH、盐度、氨氮、亚硝酸氮、硝酸氮、化学需氧量、生化需氧量、悬浮物)的变化,评价了弧形筛对废水中固体废物的净化作用。结果表明,弧形筛有效去除了废水中的固体颗粒,筛除率高达90%,起到了很好的阻截固体污染物的作用,同时增加了水体的含氧量,提高了pH值,降低了化学需氧量(COD),为后续的水处理减轻了负荷。

Arc screen Intensive aquaculture Water treatment system Purify
摘 要：
With the rapid development of aquaculture industry,the pattern of mariculture is transfering gradually from the traditional methods to the intensive farming culture in China.All of that,one of the key issues is water treatment.This paper illustrates that the solid wastes from the waste water can be effectively removed by the arc screen.The conclusion is drawn on the comparison of several key parameters of water before and after filtering through the arc screen.The results showed that the arc screen played an important role in the removal of the suspended substances at a removal rate of 90%.At the same time,the arc screen filtration process also increased pH and the concentration of the dissolved oxygen,and reduced the chemical oxygen demand,which would relieve the load of water treatment.
