摘要 自2010年12月底,南泉水源厂预处理工艺投入运行以来,以南泉水源厂出厂水为原水的中桥水厂和雪浪水厂在大多数月份矾耗明显下降。其中,中桥水厂平均矾耗降低了19.3%,雪浪水厂降低了7.6%。经分析,对净水厂矾耗的影响因素可能是:①原水经预处理后,改善了净水厂进水水质,减少了污染物对混凝的干扰作用;②臭氧预处理工艺可破坏有机物的结构,从而破坏胶体表面的有机层,使胶体颗粒在混凝过程中更易凝聚而被去除;③净水厂臭氧—生物活性炭深度处理工艺也能去除部分有机物和氨氮,提高出水水质,理论上也可降低矾耗。矾耗的降低,不仅节约了制水成本,还提高了出厂水pH,对提高管网水质和确保管网安全运行起到了积极作用。
