皮革废水处理中絮凝沉降工艺的改进探讨

Discussion on the improvement of flocculation and sedimentation process in leather wastewater treatment

皮革废水具有污染物含量高、排放量大的特点。因絮凝沉降工艺具有投资少、效率高的优良特征,皮革废水一级处理多采用絮凝沉降工艺。文章以皮革废水处理中絮凝沉降工艺为入手点,结合具体皮革废水处理工程,阐述了皮革废水处理中絮凝沉降工艺流程,探讨了皮革废水处理中絮凝沉降工艺运行问题,并对皮革废水处理中絮凝沉降工艺改进策略及效果进行了进一步分析。

leather wastewater has the characteristics of high pollutant content and large discharge.Due to the advantages of less investment and high efficiency,the first-class treatment of leather wastewater mostly adopts flocculation sedimentation process.Based on the process of flocculation and sedimentation in leather wastewater treatment,combined with the specific leather wastewater treatment project,this paper expounds the process of flocculation and sedimentation in leather wastewater treatment,discusses the operation of flocculation and sedimentation in leather wastewater treatment,and further analyzes the improvement strategy and effect of flocculation and sedimentation in leather wastewater treatment.
