摘要
Abstract
The electrochemical in-situ synthesis method was used to prepare H2O2(E-H2O2)and make it couple with O3 to form the E-H2O2-O3 advanced oxidation technology.This core technology was used to perform advanced treatment on the biochemical effluent of printing and dyeing wastewater in a pilot plant under the conditions of the E-H2O2-O3 oxidation-biological activated carbon(BAC)filtration tank process.The optimal process parameters of the E-H2O2-O3 oxidation were 120 g/h of O3 flux,0.63 mmol/L of H2O2 concentration,and hydraulic retention time(HRT)of 2.0 h.The pilot plant was operated continuously for 31 d under the process conditions(BAC contact time of 40 min),and the average removal rate of COD,UV254,and chromaticity reached 56.4%,89.5%,and 89.3%.The operating cost was about 3.35 yuan/t(calculated as wastewater).When the COD in the influent was less than 90 mg/L,the COD in the effluentwas less than 40 mg/L,which met the class V discharge standard of surface water.The total fluorescence intensity of the oxidized effluent and BAC effluent decreased by 92.0%and 96.3%,respectively,compared with the influent after treatment by the E-H2O2-O3 oxidation-BAC filtration tank process.关键词
