Analysis of Typical Cases of Comprehensive Sewage Treatment in Chemical Industry Park
There are many production enterprises and different products in chemical parks,especially in fine chemical parks.The quality of the wastewater received by the park sewage plant is complex and the organic matter is difficult to degrade.The effluent quality using A single biochemical treatment process cannot meet the A-level standard in the first-level standard of GB 18918-2002"Pollutant Discharge Standard for Urban Sewage Treatment Plants".Taking a chemical industry park in a city as an example,the incoming water quality is divided into three categories and collected according to the category and concentration of pollutants.The method of mass pretreatment is adopted,and the main treatment process is regulation + coagulation precipitation + ozone catalytic oxidation pretreatment + hydrolytic acidification +A2O+ secondary sedimentation tank + high efficiency sedimentation tank + ozone catalytic oxidation advanced treatment + activated carbon filtration.The typical cases of comprehensive wastewater treatment in chemical industry park are introduced,which can provide reference for the comprehensive wastewater treatment in similar chemical industry park,especially fine chemical industry park.
