摘　　要：随着农村生活水平的提高,饮用水安全受到威胁,适用于农村小型供水工程的生物慢滤技术可以有效去除微污染水体中的细菌等有害物质,但其维护成本较高。本文通过研究无纺布改良后的慢滤技术,降低了相关过滤过程的运行投入,并对污水处理效果进行了试验分析。结果表明,在滤池表面增加无纺布可以有效提高慢滤池中的滤料保护时长,同时对去污能力有一定提升,滤后水体满足饮用水卫生标准,具有广阔的应用前景,可为农村供水工程提供借鉴。With the improvement of living standards in rural areas,the safety of drinking water has become a concern.Biological slow filtration technology,which is suitable for small-scale rural water supply systems,can effectively remove harmful substances such as bacteria from micro-polluted water.However,its maintenance costs are relatively high.This paper investigates the slow filtration technology modified with non-woven fabric,which reduces the operational input of the filtration process and conducts experimental analysis on the wastewater treatment performance.The results show that adding non-woven fabric to the surface of the filter bed effectively increases the protection duration of the filter media in the slow filter,while also improving its decontamination ability.The treated water meets drinking water sanitation standards,demonstrating broad application prospects and providing valuable insights for rural water supply projects.
