苏湾稳定塘生态处理工程的研究与设计

Study and Design on Stabilization Pond in Suwan

研究了采用生态技术治理双洎河污染的必要性与可行性 ,设计出一种适合在我国经济欠发达地区使用的生态处理工程 .实验表明 ,在停留 2 4h时 ,CODcr的去除率可达 5 8.8% ,超过 2 4h时 ,增加不明显 ;SS的去除率在停留 2 4h时可达 5 0 .7% ,而在 36h后增加不明显 .将水利工程和污水处理厂设计技术运用到稳定塘设计之中 ,使塘内水流状况得到有效改善 ,净化效率明显提高 .实际监测表明 ,生态处理工程不会对地下水造成影响 .该工程与原拟建的污水处理厂方案相比 ,不仅满足了目前COD的削减目标 ,而且投资小。

In this paper, the necessity and possibility of treating Shuangji River with ecological technology are discussed, and a sort of ecological water treatment project which is suitable for poor economic area is designed. The results of the experiments show that 58.8% of CODcr and 50.7% of SS decrease in 24 h. The water current in the pond is improved and the decontamination efficiency is increased greatly by applying the technologies of hydraulic projects and wastewater treatment plants to the design of stabilization pond. The project will not pollute the ground water nearby and can attain the goal of COD; The investment is very low and the construction period is also very short compared with the construction of waster water treatment plant.
