Abstract: The treatment of acrylic plant biochemical pool wastewater by combined electrochemical oxidation and nano catalytic micro-electrolysis technology were studied.Using the national standard test methods to analyse four indicators which include COD,NH₃-N,pH and chromaticity.The results show that when the dosage of NaClat 0.3% and current was 9 A and the cycle time was 3.5h,the concentration of COD reduced to 46 mg/L from 227 mg/L,its removal rate reached 79.7%.The concentration of NH₃-N reduced to 9 mg/L from 117 mg/L,its removal rate reached 92.3%,chromaticity reduced to 4 times from 32 times,its removal rate reached 87.5%.Experiments show that the combined electrochemical oxidation and nano catalyticmicro-electrolysis technology in the field of organic wastewater treatment has broad application prospects.
