本研究应用臭氧净化技术治理规模化猪场废水中环境污染因子的效率。采取猪场废水收集系统、粪污固液分离系统、废水过滤系统、臭氧净化系统及粪污无害化利用系统工艺,对猪场废水中残留抗生素和细菌等环境污染因子进行治理。结果表明:经过臭氧水浓度7.8mg·L~(-1)作用20~30min净化处理后,猪场废水中残留的抗生素磺胺-6-甲氧嘧啶、磺胺嘧啶、环丙沙星、诺氟沙星、强力霉素、土霉素的降解效率分别为97.37%、96.33%、97.52%、95.46%、94.57%、93.81%;经过臭氧水浓度7.8mg·L~(-1)作用10min净化处理后,对猪场废水中各种细菌的杀菌率近于100%。
In this study, ozone purification technology is applied to control the efficiency of environmental pollution factors in large-scale piggery wastewater. Take the piggery wastewater collection system, sewage solid-liquid separation system, waste water filtration system, ozone purification system and sewage harmless utilization system technology, the pig farm wastewater residual antibiotics and bacteria for environmental pollution control. The results showed that the residual antibiotics sulfonamido-6-methoxypyrimidine, sulfadiazine, ciprofloxacin, norfloxacin in the piggery wastewater after the ozone water concentration of 7.8 mg · L ~ (-1) The degradation efficiency of star, doxycycline and oxytetracycline was 97.37%, 96.33%, 97.52%, 95.46%, 94.57% and 93.81%, respectively. After the ozone water concentration of 7.8 mg · L -1 , The bactericidal rate of the various bacteria in the piggery wastewater is nearly 100%.
