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.

采用PFS - PAM复合磁絮凝剂处理餐饮废水不仅能提高絮凝效果，还能大大缩短分离时间并减少污泥体积。

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.

本文还介绍了吸附点产生的原因以及其经时变化。
