摘要
对二氧化氯预氧化工艺替代预加氯系统处理低温、含异味和较高色度的黄河原水进行了综合研究。与预氯化、混凝沉淀系统相比,二氧化氯预氧化、混凝沉淀系统对藻类的去除率提高了30%-40%,使嗅和味的阈值降低了10～20,但CODmn和氨氮的去除率的变化不明显。由于进水色度变化较大,对色度的去除率变化也不明显。运行证明,该系统改造后对降低以微污染黄河水为水源的北方给水处理厂冬季运行过程中的出水嗅和味的阈值、增加藻类的去除率具有明显的效果,同时,运行费用也较低。
This work study on the treatment of Yellow River water with character of low temperature、high taste and odor、high ＊ by chloline dioxide. By the way of pre - oxidant , quite good removals of 30% - 40%, 10 - 20 are obtained for algae, the taste and odor. And the remorals of CODmn and NH3 - N is not extraordinary. All these shown that it is efficient to removal the algae,the taste and odor for the drinking water treaunent plant using Yellow River water in winter pre- oxidanttlng by chlorine dioxide.
