芬顿+电氧化法处理沼液膜滤浓缩液的试验研究

Experimental research on the treatment of anaerobic biogas slurry membrane filtration concentrate by fenton oxidation+electro-oxidation method

采用芬顿+电氧化法处理沼液膜滤浓缩液,试验结果表明:在p H值为3、七水硫酸亚铁投加量为3.475 g/L、双氧水投加量为10 m L/L、电流为1.8 A的情况下,氧化1.5 h后沼液膜滤浓缩液可以达到《广东省污水综合排放标准》(DB 4426—2001)第二时段排放标准,水处理费用为44.46元/t。

Fenton+electric oxidation method was used to treat the methane membrane filtration concentrate.The test results show that the methane membrane filtration concentrate could reach the discharge standard of the second period of"Guangdong Province Comprehensive Sewage Discharge Standard"DB 4426—2001 after oxidation for 1.5 h at pH 3,ferrous sulfate heptahydrate dosage of 3.475 g/L,hydrogen peroxide dosage of 10 mL/L and current of 1.8 A.The cost of ton of water treatment is 44.46 Yuan/ton of water.
