雨水处理不同工艺的比较

摘要

以雨水回用处理为研究对象,比较两种不同方式的微絮凝过滤处理,结果表明:由轻质滤料组成的双重滤料与传统砂滤相比水力负荷高,工作周期长;采用轻质滤料与颗粒活性炭联用直接过滤也可收到较好的处理效果,生物稳定性较好;轻质滤料+砂滤工艺单位产水量综合成本最低.%Based on water reuse treatment as the research object,two different ways of micro flocculation and filtration were compared.Results showed that double filter material composed of light filter material had higher hydraulic loading,long working period compared with traditional sand filter.Using lightweight filter and granular activated carbon conjunction with direct filtration could also receive better treatment effect and better biological stability.Besides,double filter material composed of light filter and sand filter had low comprehensive cost of unit water production.
