Research on aeration coagulation for secondary sedimentation tank effuent of municipal wastewater
城市污水处理厂二沉池出水曝气混合絮凝的研究

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.
