摘要:
针对猪场沼液含氮磷高、可生化性差等特点，江西某养猪场采用两级A/O+絮凝沉淀组合工艺处理猪场沼液，处理规模为1 500 m3/d，工程总投资为1 200万元，运行费用为3.30 元/m3。运行结果表明，经过该组合工艺处理后，COD、NH3-N、PO3-4-P去除率分别为89.3%、99.1%、99.7%，出水各项指标稳定达到《污水综合排放标准》（GB 8978—1996）的一级排放标准。
Abstract:
In view of the characteristics of high nitrogen and phosphorus content, poor biodegradability of piggery bio-slurry, the combined process of two-stage A/O, flocculation and sedimentation has been adopted at a pig farm in Jiangxi Province. The treatment capacity is 1 500 m3/d, the total project investment is 12 million yuan and operation cost is 3.30 yuan/m3. The results showed that the removal rates of COD, NH3-N and PO3-4-P were 89.3%, 99.1%, 99.7%, respectively. The effluent indexes met the first-level discharge criteria of Integrated Wastewater Discharge Standard (GB 8978-1996).
