摘要
城市滞留型河道水质多属于高浊度难降解的黑臭水体,通过实验室模拟混凝-双微滤组合工艺对水质净化试验,结果表明当PAC投加量为20mg/L时,其过滤通量较高并接近于原水,水质净化效果也明显强于直接过滤和絮凝-过滤.依据前期研究成果制造了采用曝气-混凝-双微滤组合工艺的一体化移动式净水设备,并对城市重污染河道进行中试试验,短时间内改善多项水质指标:DO由0.28 mg/L升至9 mg/L,透明度由35.3cm升至83.4cm,COD、TN、TP和浊度平均去除率分别为61.5%、52.5%、63.2%和81.8%,水体黑臭得到去除。该净化设备单位容积处理量达到180~220[m3/(d·m3)],水处理成本在1.37-2.78元/m3左右,符合低成本处理水要求;并且其机动性能强,应用前景广阔。
Detention Landscape Urban River was one kind of the typical recalcitrant with high turbidity wastewater,Through the laboratory simulation, the results showed that the technology of Coagulation-Double Microfiltration had very high filtration-flux when PAC was 20mg/L,and as compared to direct filtration and flocculation-filtration, the removal of water quality was much more better. Then the integrated movably equipment which used the technology of Aeration and Coagulation-Double Microfiltration was used to treat the seriously contaminated urban river, multi-index of water quality were controlled in short time: DO increased from 0.28mg/L to 9 mg/L, the transparency from 35.3cm to 83.4cm, the average removal rates of the turbidity、COD、TN and TP reached 81.8%、61.5%、52.5% and 63.2% respectively,black-odour had been also removed. The unit volume throughput had reached 180~220 [m3/(d·m3)], and the water treatment cost about 1.37~2.78 yuan/m3, it was conformed to require with water treatment in low cost and nice maneuverability, so it has a wide application in the future.
