摘　　要：在污水处理厂实验室，对二沉池出口污水进行了曝气和机械2种方式的混合絮凝对比试验。研究结果表明，对于同一水质，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：BOD56％～9％，COD4％～6％，NH3-N6％～9％，TP15％～24％，SS8％～18％。Both aerated coagulation and mechanical coagulation were 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 6 - 9 percent in BODs, 4 - 6 percent in COD, 6 -9 percent in NH3-N, 15 -24 percent in TP and 8 - 18 percent in SS.
