摘要
Abstract
Economical treatment of non-degradable industrial wastewater in industrial zones has been an urgent problem to be solved.The wastewater treatment plant(WWTP)of an industrial zone in Yichang City mainly accepts the refractory industrial wastewater after pretreatment from paper mills and food processing plants,which has been facing the problem of substandard effluent and high operation cost for a long time.In this study,the non-degradable organic pollutants in the current WWTP were taken as the research object,and the Fenton-like catalytic oxidation experiment was carried out.The results showed that when pH value was adjusted from 5.0 to 5.5,the overall removal rate of CODCr by Fenton-like advanced treatment process could reach more than 73%,the effluent quality could reach the first grade A discharge standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002)stably,and the additional pharmaceutical cost was 0.905 yuan/m3.Based on the test results,combined with the existing land and WWTP structures layout,the advanced treatment technology based on Fenton-like catalytic oxidation was proposed.It can provide reference for the upgrading of similar WWTPs with high proportion of industrial wastewater.关键词
