摘　　要：在污水处理厂实验室,对沉砂池出口污水进行了曝气和机械两种方式的混合絮凝对比试验。研究结果表明,对于同一水质条件,在相同的投药量下,曝气混凝沉淀后的水质明显优于机械混凝沉淀后的水质,各项水质指标的去除率分别提高:BOD5 3％-5％,CODCr16％-17％,NH3-N 3％-7％,TP 12％-18％,SS 4％-16％。Both aerated coagulation and mechanical coagulation have been tested and compared in the lab of a sewage treatment company. It shows that the water quality after aerated coagulation and sedimentation exceeds the one with mechanical coagulation to a certain extent, relatively by 3-5 percent in BOD5, 16-17 percent in CODCr, 3-7 percent in NH3-N, 12-18 percent in TP and 4-16 percent in SS.
