摘　要：采用蒸馏加絮凝法去除丁硫克百威生产废水中的COD、呋喃酚和硫化物。通过单因素实验考察了初始废水pH、絮凝反应pH、絮凝剂投加量等主要因素对废水中COD、呋喃酚和硫化物去除率的影响。结果表明，去除丁硫克百威生产废水中的COD、呋喃酚和硫化物的优化条件为：废水初始pH=13.0、絮凝反应pH=7.0、絮凝剂投加量为废水质量的0.5%，相应的COD、呋喃酚和硫化物的去除率分别为91.2%、93.3%和81.0%，BOD5／COD由最初的0.06上升至0.51，可生化性显著提高，且废水毒性大大降低。

Abstract：The treatment of carbosulfan wastewater by distillation and flocculation process was studied in this paper. The effects of initial wastewater pH, flocculation pH and flocculant dosage on the removal of COD, benzofuranol, and sulfide of carbosulfan wastewater were investigated by single factor tests. Results showed that the optimum reaction conditions were initial wastewater pH 13.0, flocculation pH 7.0 and flocculant dose at 0.5% of wastewater mass. And under these conditions, the COD, benzofuranol and sulfide removal rate were 91.2%, 93.3% and 81.0% respectively, and BOD5/COD increased from 0.06 to 0.51. Meanwhile, the biodegradability of carbosulfan wastewater was improved, and toxicity was decreased significantly.
