摘要
以改性硅藻土为混凝剂,对具有不同污染特征的苏州河各支流污染水体进行了化学强化一级处理试验研究。结果表明,硅藻土混凝剂的最佳投药量随原水水质的不同而不同;硅藻土对COD+(Cr)和P有较高的去除效率,而对NH_3-N的去除率不高;不同污染河水水质对硅藻土的混凝效果有比较显著的影响,表现为在混凝剂的最佳投药量条件下,COD_(Cr)去除量与原水COD_(Cr)之间存在着显著的线性关系。
An experimental study on CEPT (Chemically Enhanced Primary Treatment) technology applied to treatment of polluted river water with different polluting characteristics of subsidiary stream of Suzhou Creek has been conducted. In this study, diatomite was used as flocculation agent. The results showed that the optimum feeding concentration of diatomite was varied with water quality. The removal efficiency of CODCr and P was high and NH4-N was low. Under optimum feeding concentration, the removal amount of CODCr was significantly linear with the CODCr value of the river water.
