SBR—混凝沉淀处理织棉漂白废水研究

Study on Treatment Process of Fabric Blanching Wastewater Using SBR-Coagulation Subsiednee Method

研究了 SBR—混凝沉淀工艺对织棉漂白废水的处理效果 ,结果表明 :进水 CODcr为 10 6 0 mg/ L,经 SBR工艺处理 ,CODcr去除率达到 79%。以聚铁— PAM作后续处理 ,可进一步把 CODcr降到 10 0 mg/ L以下 ,并能有效去除色度 ,去除率达 94% ,出水达到排放标准。

The experiments o f treating fabric blanching wastewater have been finished using SBR-Coagulated Subsidence Method.By using SBR,the removal efficiency of CODcr can reach 79%.By using coagulated subsidence as successive treatment method,the CODcr can be reduced to less than 100mg/L and the color can be largely removed,the removal efficiency reached 94% The final effluent quality has met discharge standards.This method is less cost in running and more efficient.
