混凝气浮及SBR法处理化学药剂废水的工程实践

Engineering Application of PEG Wastewater Treatment by Coagulation /DAF and SBR

采用混凝气浮+SBR生化法处理某化学药剂生产企业废水,工程应用实践表明,混凝加药和气浮处理可有效去除废水中的油和非溶解性COD,COD总去除率达到94.3%,出水达到企业排放要求。

Coagulation,flocculation and dissolved air floatation（ DAF） processes are used to pre- treat the oil and suspended solids in the influent wastewater. The pre- treated effluent is further treated to remove the organic pollutants by sequencing batch reactor（ SBR） method. Engineering application shows that the total COD removal rate can reach 94. 3% and the effluent can meet the discharge requirements.
