摘　　要：利用风成沙净化污染水试验,结果表明,在水力负荷为1.0m d、湿干周期比为12h∶12h或48h∶48h条件下,风成沙处理污染水系统对BOD5处理效果较好,出水ρ(BOD5)≤2mg L,优于《地表水环境质量标准(GHZB1-1999)》Ⅰ类标准。影响处理效果的因素主要有湿干周期比、水力负荷和接种驯化方式等。The experiment results shows, using anemoarenyte as filter media, on the condition that hydraulic loading rate was 1.0 m/d, and flooding-drying ratio was 12h∶12h or 48h∶48h, the anemoarenyte system can remove BOD5 efficiently. The concentration of BOD5 in the effluent is less than 2 mg/l, which is surpassed to the class I of environmental quality standard of BOD5in water (GHZB 1-1999). The performance of the process is affected by the ratio of humid-dry, hydraulic loading rate, filter depth and the method of microbes, etc.
