摘要
试验表明 ,在水力负荷为 1 .0～ 1 .5m/d ,沙层湿干时间比为 1 2∶1 2 (h)条件下 ,风成沙污染水处理系统稳定后对化学需氧量 (CODCr)平均去除率约为 61 % ,CODCr<1 5mg/L ,优于《地表水环境质量标准 (GHZB1 -1 999)》规定的Ⅰ类标准。影响处理效果的因素主要有进水水质、沙层湿干时间比。
Pilot experiment of removing COD Cr in water in Guanting Reservoir by aeolian sand system was carried out. The result shows that, when the hydraulic loading rate is 1.0～1.5 m/d and flooding drying ratio is 12 hrs∶12 hrs, the average removal rate of COD Cr is 61%, and the COD Cr concentration becomes less than 15 mg/L which satisfies the quality standard GHZB1 1999 for surface drinking water. The effect of the treatment is affected by influent water quality, flooding drying ratio, hydraulic loading rate and filter depth etc.
