水解酸化-A/O-化学混凝沉淀工艺处理活性染料印染废水的设计与运行

Hydrolysis Acidification-NO-the Chemical Process on Coagulating Sedimentation Design and Operation on Printing and Dyeing Wastewater of Reactive Dyes

水解酸化-A／O．化学混凝沉淀处理活性染料废水，即在传统的好氧池前设置缺氧池，使微生物在缺氧／好氧（A／O）状态下交替进行，有效去除了废水中的有机物，使处理后的出水达到污水综合的排放标准。即CODcr≤100mg／L，悬浮固体浓度（SS）达100～300mg／L色度≤50倍，PH=6～9。

The article briefly introduces design and operation process of Hydrolysis Acidification-A/O-the Chemical Process on Cogulating Sedimentation on the printing and Dyeing wastewater brought by reactive dyes.After this treatment, the quality of the water can meet the national stipulation about comprehensive discharge standard of sewage, i.e,,CODcr≤100mg/L,SS index for the concentration of suspended solids reaches 100-300mg/L,chromaticity≤50times,pH=6-9.
