摘要
依据生态经济学和循环经济学原理,将厌氧生物技术、接触氧化技术以及综合利用技术进行组合来治理养殖场污水。结合福州市闽侯荆溪福建省农科院种猪场污水治理工程实践,表明该技术可以解决禽畜养殖业的废水污染问题,处理后水质:CODCr为58 mg.L-1、BOD5为13.3 mg.L-1、SS为72 mg.L-1、NH3-N为34.9 mg.L-1,TP为7.2 mg.L-1,均符合国家《畜禽养殖业污染物排放标准》规定的要求,而且工程运行效果稳定,经济效益和生态效益显著。
According to the principle of circular economy and ecological economy, the technology of anaerobic and aerobic fermentation has been combined with a comprehensive utilization route to control sewage pollution in livestock and poultry farm. The practice of sewage treatment in intensive feeding farm in Jingxi Town of Minhou County of Fuzhou City, showed that the sewage pollution in animal husbandry industry could be solved by such a route. The treated sewage indexes for CODe,, BODs, SS, NH3-N, and TP reached 58 mg·L^-1 , 13.3 mg·L^-1 , 72 mg· L^-1 , 34. 9 mg · L^-1 , 7.2 mg·L^-1 , respectively, which reach the Intergratel Pollutant Discharge Standard according to “The drainage standard for sewage from livestock and poultry production”. The project was run steadily and a remarkable benefits in economy and ecology have been obtained.
