摘　　要：研究了二氧化氯和过氧乙酸对啤酒废水污泥的无害化处理。结果表明，经二氧化氯处理2～3h后．污泥中细菌、放线菌、真菌菌落数目分别为6×10^4cfu／g、8．3×10^3cfu／g和900cfu／g，粪大肠杆菌和蛔虫卵被杀灭，有机质、总氮损耗分别为29．4％和21．9％；经过氧乙酸处理0．5～1h后，污泥中细菌、放线菌和真菌菌落数目分别为2．8×10^5cfu／g、2．8×10^3cfu／g和130cfu／g，粪大肠杆菌和蛔虫卵被杀灭，有机质损耗为3．2％，总氮损耗为18％。过氧乙酸的无害化处理优于二氧化氯。The harmless treatment of brewery wastewater sludge by peracetic acid and chlorine dioxide respectively was investigated. The results showed that, 2 ~ 3 h after chlorine dioxide treatment, the number of bacteria, actinomycetes and fungus in sludge were 6×10^4 cfu/g, 8.3 ×10^3 cfu/g and 900 cfu/g respectively, the fecal e.coli and ova of roundworm were sterilized, and the loss of organic substances and total nitrogen were 29.4 % and 21.9 %, respectively; 0.5-1 h after peracetic acid treatment, the number of bacteria, actinomycetes and fungus in sludge were 2.8×10^5 cfu/g,2.8×10^3 cfu/g and 130 cfu/g repectively, the fecal e.coli and ova of roundworm were sterilized, and the loss of organic substances and total nitrogen was 3.2 % and 18 %, respectively. As a conclusion, peracetic acid treatment was better than chlorine dioxide treatment.
