| 摘 要： | 采用生物快滤池对城市污水厂二级出水进行深度处理的试验表明,生物快滤池对进水水质变化有很大的适应性,除卫生学指标外,其它指标出水绝大部分时间可满足生活杂用水水质标准(CJ25.1-89)中的洗车标准。随着进水水质的不同,生物快滤池中生化反应类型也随之变化,相应地滤池出水pH值也有不同的变化规律。可以通过生物快滤池进出水pH值的变化情况来判断滤池内生化反应类型和COD或氨氮指标的去除效果。

| Abstract: | Rapid biological filter was used for advanced treatment of effluent from a secondary treatment wastewater plant.The results showed that rapid biological filter had high flexibility for the variation of secondary effluent quality.Except for hygienic index,the effluent of rapid biological filter can reach vehicles washing water standard in CJ25.1-89 at most time of our test.Corresponding to the change of influent quality,the type of biochemical reaction is changed in rapid biological filter,which could be reflected from the change of its effluent pH value.Thus,the effluent pH value can be an indicator for the type and the degree of biochemical reaction in rapid biological filter. |
