| 摘 要： | 为了解决由于高藻水源水引发的产水量下降、滤池反冲洗周期缩短、出水余铝超标、投药量大幅增加以及出水嗅味严重等问题,采用沉淀/高速气浮联用技术对水厂的平流沉淀池进行改造(不增加占地),并加设静态混合器,改善絮凝剂的混合效果.改造后的运行结果表明,出水水质完全满足国家饮用水卫生标准,高藻暴发期间投药量仅为改造前的1/3. |

| Abstract: | In order to solve the problems caused by the high algae-laden source water,such as reduced water production,shortened backwashing interval of filter,residual aluminum exceeding standard,increased chemicals dosage and bad odor of outflow,the sedimentation and high-rate air flotation combination technology was adopted to reconstruct the horizontal-flow sedimentation tank in the waterworks.A static mixer was extra installed to improve the mixing effect of flocculant.The operation results after the reconstructi... |
