摘  要:
研究混凝沉降对织物洗涤废水中阴离子表面活性剂和化学需氧量的去除效果。通过考察混凝剂的种类、用量、废水p H、混凝剂投加水力条件等方面,确定了最佳的混凝沉降条件。在最佳试验条件下通过混凝沉降处理可达到87.6%的LAS去除率,和72.7%的COD去除率。

摘  要:
Coagulation and sedimentation were used to remove the LAS and CODcr in textile washing wastewater.The best experimental conditions were screened by changing the kinds of coagulant, dosage, p H and hydraulic conditions. The results showed that under the optimum conditions, the removal rate of LAS and COD reached 87.6% and72.7% respectively.
