摘要: 以臭氧净化技术为主导，实施猪场粪污电动清扫、粪污固液压滤分离、石英砂罐过滤和臭氧净化处理等技术，实例探讨猪场粪污处理工艺的可行性。结果表明，电动粪污清扫车的干清粪工艺治理粪污的效率是水冲粪方式的8～15倍；粪污经过浓度为7.8 mgL的臭氧水作用10 min后，pH、SS、NH3-N、TP、COD、BOD及Cu、Zn处理效率分别为12.20%、97.54%、89.80%、94.74%、96.55%、91.73%、77.85%和91.28%；粪污中磺胺嘧啶、磺胺甲基异恶唑和磺胺吡啶等磺胺类抗生素降解效率分别为97.37%、96.23%和93.64%；粪污中细菌与肠菌群净化处理效率接近于100%。净化处理后的水质达到GBT 18596—2001《畜禽养殖业污染物排放标准》的排放要求。Abstract: Taking ozone purification technology as dominant，cleaning dry manure by electric cleaning machinery，solid-liquid separation by filter press，filtering by quartz sand，and ozone purification treatment technology were carried out in order to explore feasibility of treatment of piggery wastewater process.Results showed that working efficiency of cleaning dry manure by electric cleaning machinery was 5 to 15 times better than the way of water flush excrement.Treatment by ozonated water with the concentration of 7.8 mgL for 10 minutes caused the value of pH and the concentrations of SS，NH3-N，TP，COD，BOD，Cu and Zn in manure decrease by 12.20%，97.54%，89.80%，94.74%，96.55%，91.73%，77.85% and 91.28% respectively.Degradation efficiency of sulfadiazine，sulfamethoxazole，sulfapyridine were 97.37%，96.23% and 93.64% respectively.Treatment efficacy of total number of bacteria and intestinal flora was almost 100%.Treated water met the emissions requirements of GBT 18596—2001‘Livestock and Poultry Breeding Industry Pollutant Discharge Standards’.
