Abstract:

通过中试,研究一体式PAC-UF工艺取代传统砂滤池工艺的适用性和经济性,并将其与单独超滤和水厂砂滤池比较.结果表明,PAC-UF工艺平均出水浊度为(0.041±0.010)NTU,粒径>2μm的颗粒数平均为(13±8)/mL,可保证出水良好的生物安全性.在PAC投加20mg/L情况下,PAC-UF工艺对CODMn的去除率为(21.0±9.9)%,对不含亚硝酸盐部分CODMn的去除率为(33.7±11.1)%,对UV254的去除率为(51.0±10.7)%,PAC-UF工艺对浊度和有机物的去除效果明显优于传统砂滤.但PAC-UF工艺对NH4+-N去除效果不佳.在实验工况条件下,工艺能稳定运行,可以维持运行3个月左右化学清洗1次.PAC-UF工艺适用于高有机污染、低NH4+-N的原水水质,它可以有效地提高水厂出水的生物安全性和化学安全性.
