摘要

双氧水废水具有高CODcr、低B/C、可生化性差的特点,采用芬顿-MBBR组合工艺对其进行处理.试验结果表明:当H2O2投加量为4 mL/L,H2O2/Fe2+物质量的比为2时,芬顿-MBBR组合工艺对双氧水废水有良好的CODcr去除效果.芬顿预处理后,B/C由0.11提高到0.47,在连续进水条件下CODcr去除率为77.7％,生化单元出水CODcr质量浓度小于500 mg/L.

Abstract

Hydrogen peroxide wastewater has the characteristics of high CODcr,low B/C and poor biodegradability.The wastewater was treated by Fenton catalytic oxidation-MBBR combined process.The results showed that when H2O2 dosage was 4 mL/L and H2O2/Fe2+molar ratio was 2,the Fenton catalytic oxidation-MBBR combined process had a good COD removal effect on hydrogen peroxide wastewater.After the wastewater was pretreated by Fenton catalytic oxidation,the B/C ratio of the wastewater increased from 0.11 to 0.47.The CODcr removal rate reached 77.7％and the CODcr concentration out of biological treatment unit subjected to continuous feed was less than 500 mg/L.
