基于羟基催化氧化法处理紫胶生产废水工艺研究

Treatment of wastewater from LAC production by electro-catalytic oxidation process and microbial flocculation

以紫胶生产废水为研究对象,研究了羟基催化氧化法+微生物絮凝作为紫胶废水生化处理工艺前的预处理工艺的可行性和有效性。结果表明:羟基催化氧化法可有效降解紫胶废水中的污染物,并提高可生化性,B/C由0.23提高至0.51,同时降低氯离子浓度,经过40 min羟基催化氧化处理CODCr去除率达到46.7%,结合微生物絮凝处理CODCr去除率达到72%,同时降低氯离子浓度32%,为解决紫胶生产企业废水的达标排放提供了一种新途径。

The paper focuses on the treatment of wastewater from Lac production by electro - catalytic oxidation process combined with microbial flocculation. The results indicated that advanced oxidation process can effectively remove pollutants in wastewater from Lac production, increase biodegradability and reduce the chloride ion concentration in the meantime. After 40min electro -catalytic oxidation process, CODcr removal rate reached 46.7% ,CODcr removal rate combined with flocculation reached 72% while reducing the chloride concentration of 32%. The method can provide a new way for Lac production enter- prise to solve the discharge of wastewater.
