摘要
通过对调理后生化污泥含水率的测定试验,考察了生石灰、三氯化铁、粉煤灰和煤粉等4种调理剂对污水处理厂生化污泥脱水性能的影响。结果表明:生石灰和三氯化铁对污水的脱水效果较好,且最经济投加量分别为4、2g/100mL,在该条件下,相对于原污泥,抽滤后调理污泥含水率分别降低7.07%和15.22%。
Influences of four kinds of conditioner on biochemical sludge dewatering characteristics of sewage treatment plants were studied by moisture content determining experimentations of treated sludge, such as lime, iron trichloride, fly ash and coal powder. The results showed that the dewatering effect of lime and iron trichloride was better, and most economical dosages of lime and iron trichloride were 4 g/100 mL and 2 g/100 mL respectively. Under these conditions, the moisture content of the conditioned sludges were 7. 07% and 15. 22% lower than the original sludge.
