摘　　要：通过烧杯试验，在不加助凝剂、不调整ｐ Ｈ 的条件下，研究了化学强化一级处理对低浓度生活污水的处理效果，确定了最佳投药量，探讨了絮凝剂对悬浮性 Ｃ Ｏ Ｄ（ Ｃ Ｏ Ｄｓ） 及溶解性 Ｃ Ｏ Ｄ（ Ｃ Ｏ Ｄｄ） 的去除关系。并通过药剂负荷概念的提出，比较了不同药剂的去除效果。最后，与 Ｃ Ｅ Ｐ Ｔ 处理普通生活污水效果进行了比较。he chemically enhanced primary treatment (CEPT) of low concentration domestic wastewater was researched by jar test without coagulation aid dosing and pH conditioning.The optimal coagulant dosage was determined and the effect of coagulant on the removal of both COD\-s (suspended) and COD\-d(dissolved) was discussed.Finally a concept of agent dosage load was proposed to compare the removal capacities of different chemicals.Also the results with CEPT to treat conventional and low concentration domestic wastewater were compared.
