微絮凝与滤布滤池组合工艺在城市景观用水水质提升中的应用

Application of Micro Flocculation and Filter Cloth Filter Combination Process in Improving the Quality of Urban Landscape Water

为了提高城市景观用水水质,项目采用微絮凝与滤布滤池组合工艺对京杭运河水进行处理。运行结果表明,微絮凝与滤布滤池组合工艺能够显著降低水体浊度,提高水体透明度。在PAC投加量为6 mg/L时,原水SS从52 mg/L降至9 mg/L,去除率为82.7%;TP从0.32 mg/L降至0.16 mg/L,去除率为50%;浊度从49.2 NTU降至4.6 NTU,去除率为90.7%;水体透明度显著提高,水质感官品质改善明显。此外,该系统还具有工艺运行稳定、占地面积小、建设周期短、自动化程度高、运行费用低等特点,因而适宜于城市景观水体水质的提升需求。

In order to improve the quality of urban landscape water,the project adopts a combination process of micro flocculation and filter cloth filter to treat the Yunhe River in Beijing and Hangzhou.The operation results show that the combination process of micro flocculation and filter cloth filter can significantly reduce water turbidity and improve water transparency.When the PAC dosage is 6 mg/L,the SS in the raw water decreases from 52 mg/L to 9 mg/L,with a removal rate of 82.7%;TP decreased from 0.32 mg/L to 0.16 mg/L,with a removal rate of 50%;The turbidity decreased from 49.2 NTU to 4.6 NTU,with a removal rate of 90.7%;The transparency of water bodies has significantly improved,and the sensory quality of water quality has significantly improved.In addition,the system also has the characteristics of stable process operation,small footprint,short construction period,high automation level,and low operating costs,which is suitable for improving the water quality of urban landscape water bodies.
