摘 要: | 考察了硅藻土强化ALB工艺对重庆城镇生活污水的处理效果,并研究了硅藻土的最佳投加量。结果表明,硅藻土强化ALB工艺能较好地提高出水水质,COD、氨氮、总氮、总磷的去除效果均有不同程度的加强。各项水污染物质去除率随硅藻土投加量的增加,总体上呈先增加后减少的趋势,最适投加量为30 mg/L,出水中COD、氨氮、总氮均达到了排放一级A标准,总磷达到了排放一级B标准。硅藻土作为ALB工艺的混凝剂经济可行,效果良好。

Treatment of Domestic Sewage in Chongqing Areasby Diatomite-ALB Process |
| |
Abstract: | The effects of treatment of domestic sewage in Chongqing areas by diatomite-ALB process was investigate. The optimal dosage of diatomite in diatomite-ALB process was studied. The results showed that diatomite-ALB process could improve the effluent quality, and the removal rates of COD, NH4+-N, TN, TP had increased respectively. As the dosage of diatomite increased, the removal of water pollutants increased at first, and then decreased in generally. The optimal dosage of diatomite was 30mg/L. The effluent quality of COD, NH4+-N, TN met the first level A criteria and TP met the first level B criteria in the national wastewater discharge standard. Diatomite as coagulant for ALB process is economical, with a good effect. |
