Adopting combined PFS-PAM magnetic flocculant for treatment of restaurant wastewater can not only heighten the flocculation effect, but greatly shorten the separation time and decrease sludge volume.
At the same time, the chemical and physical methods of coagulation, flocculation, settlement and sand filtering process are also feasible to remover COD in SBR effluent.
同时，混凝、絮凝沉淀及砂滤法等化学、物理方法对于去除SBR出水中的COD也是可行的。

Thus, flocculation structure is crashed. The causes of adsorption point and its changes with time are also discussed.
