Fenton耦合微电解-混凝-吸附工艺处理氧化塘浓缩染料废水
Disposal of lagoon concentrated dye wastewater by Fenton microelectrolysis-coagulation-adsorption technology
摘要
Abstract
The method of Fenton microelectrolysis- coagulation- activated carbon adsorption was used to treat lagoon concentrated wastewater of dye intermediates plant, and the best conditions were obtained. The results showed that: in Fenton- microelectrolysis process, the dosages of sponge iron, activated carbon, H2O2, FeSO4 were 150 g/L, 150 g/L, 200 mL/L, 40 g/L, respectively, the best reaction time was 4 h, the COD and chromaticity of effluent were 1360 mg/L and 512 times. In flocculation process, pH=8, PFS for coagulation was 100 mg/L, the COD and chromaticity of effluent were 972 mg/L and 32 times. In adsorption process, the dosage of activated carbon was 10 g/L, the effluent COD and chromaticity were 496 mg/L and 2 times. The dye wastewater treated by the method of Fenton microelectrolysis- coagulation- activated carbon adsorption was up to the standard of "Water quality standard for sewage discharged into the city" (CJ 343- 2010), the COD and chromaticity of effluent were 496 mg/L and 2 times, and the COD and chromaticity removal rate were 97.7%and 99.9%.关键词
