摘要
本文采用高效絮凝模拟反应器进一步对实际生活污水进行连续运行处理试验,结果表明,直接絮凝沉淀处理后的出水浊度去除率和COD去除率分别达到93.4％和79.2％,可完全达到排放标准。絮凝处理后再经纤维过滤柱过滤处理,可控制出水浊度在1.0NTU以下,COD去除率增加5.0—7.0％.试验结果进一步验证了这种高效絮凝装置具有高效处理效能及实际工程应用推广价值。
The coagulation and flocculation test for municipal wastewater treatment was studied with the high-efficiency flocculation reactor. Results show that removal efficiency of turbidity and COD from municipal wastewater are 93- 4% and 79. 2%. If the treated water was filtrated further by the fiber filtrates, the turbidity removal can achieve to 1. 0 NTU and the removal efficiency of COD is increased to 84-86%. It can meet the discharge standard. The experimental results further show that the high-efficiency flocculation reactor has the high treatment effect for municipal wastewater and high value in engineering applications.
