| 摘 要： | 猪场废水是一种高浓度有机废水,里面含有大量的有机物、氮、磷、悬浮物等污染物质,直接采用传统的工艺处理很难达到排放标准。本试验采用化学混凝/倒置A2/O工艺处理猪场废水,效果较好。通过比较,发现采用FeC l3为混凝剂1 400 mg/l时对废水的絮凝效果最好,而好氧区HRT为7 h回流比为200%时对有机物及氮的去除效果最好。

| Abstract: | Piggery wastewater, which has a large quantity of organic matter, nitrogen, phosphorus, suspended solids, is a kind of higher concentration wastewater. It is difficult to meet the discharge standard by disposal of traditional treatment process. This experimentation focus on the treatment of piggery wastewater through using chemical flocculation/inverted A2/O process. It has good flocculent effect with the dosage of FeC131 400 mg/l and has high removal rate of organic matter and nitrogen with sludge return ratio 200% and HRT 7 h. |
