聚合硫酸铁净化厌氧发酵废水的研究

Study on purification of anaerobic ferment wastewater in city life rubbish

通过对用液体聚合硫酸铁处理城市生活垃圾厌氧发酵废水的 ,结果表明 :最佳条件为聚铁投加量 4.7～ 5.3g/L、p H=5～ 9沉降时间 2 h左右 ,经处理后 COD去除率可达 92 .5%左右。

The purification of anaerobic ferment wastewater in city life rubbish is sludied. The rusult shows that the optimization of PFS is 4.7~5.3 g/l,pH=5~6, and the sedimentation time of 2 hour or so, the removal ratio of COD is about 92.5% after handling.
