摘要
针对丙环唑废水COD浓度高、成分复杂、难生物降解等特点,首先采用氯气氧化方法回收废水中的溴,再采用铁碳微电解法处理废水。经过预处理后,废水中溴素的回收率为96%,废水的COD去除率达到90.5%;处理后废水的BOD5/COD由0.11提高到0.36。经好氧生化处理后出水符合国家一级排放标准(GB8978–1996)。
Propiconazole waste water was characterized by high concentrations of COD, complex composition, and weak biodegradability. First of all, the chlorine oxidation method was used to recycling bromine from the waste water, and then iron carbon micro-electrolysis method was used to the treatment of waste water. After pre-treatment, the recovery rate of bromine was 96%, the COD removal rate reached 90.5%. Treated waste water improved BOD5/COD from 0.11 to 0.36. The water quality satisfied the National Primary Discharge Standard （GB 8978 - 1996）.
