Abstract

This study is a factory waste paper pulping wastewater of Shandong Zibo as treatment object, with ozone generator homemade ozone water, hydrogen peroxide, activated carbon, aluminum sulfate, polyacrylamide, manganese dioxide co-processing, combined with flocculation and sedimentation, adsorption, filtration, sewage after treatment fully meet the standard recycling. Experimental findings show that the ozone-water continuous separate treatment wastewater at temperature (20øC) and pH 6.91 for 70min, COD, BOD, TOC, SS, and chroma of wastewater is respectively from the original 2660mg/l, 1962mg/l, 1165mg/l, 707mg/l and 120 times reduced to 1308mg/l, 1108mg/l, 142mg/l, 80mg/l and 50 times. The ozone-water with ozone-catalytic oxidation - activated carbon - hydrogen peroxide- flocculants - filtration to co-treatment wastewater at temperature (20øC) and pH 6.65 condition for 70min, COD, BOD, TOC, SS and chroma of wastewater respectively from the original 2660mg/l, 1962mg/l, 1165mg/l, 707mg/l and 120 times reduced to 384mg/l, 401mg/l, 74mg/l, 39mg/l and 30 times by method of using hydrogen peroxide 60mmol/l, activated carbon 220mg/l, aluminum sulfate 25mg/l, PAM 15mg/l, manganese dioxide 10mg/l of wastewater
