人工快速渗滤系统处理城镇生活污水

Constructed Rapid Infiltration System for Municipal Domestic Sewage Treatment

采用渗透性能良好的人工快速渗滤介质既有较高的水力负荷,又能满足出水的处理目标。系统采用干湿交替的运转方式,使污水在流经快渗池时既产生吸附、截留作用又产生化学和生物反应,污染物得以有效去除。人工快速渗滤系统在处理城镇生活污水有明显技术经济优势,具有建设和运行成本低、运行稳定、建设周期短、出水效果好的优点,是比较适合我国国情的污水处理工艺。

With good permeability of constructed rapid infiltration medium is not only a higher wastewater treating capabilities, but also to meet the water treatment goals. System using of alternating wet and dry in the functioning of the sewage infiltration enable adsorption, retention as well as chemical and biological reactions effected when the sewage flows across the rapid infiltration pond, therefore contaminants can be removed effectively. Constructed rap- id infiltration has the significant technical and economic advantages in dealing with mainly municipal domestic sew- age, Such as the low cost of construction and operation, stable operation, short construction periods, the water effects of a good advantage, so it is more suited to China＇s national conditions of the sewage treatment process.
