循序间歇式活性污泥法处理造漆工业废水

A Study on the Treatment of Paint Wasterwater by a Sequencing Biological Batch Reactor.

循序间歇式废水生物处理工艺(SBR工艺)集进水、厌氧、好氧、沉淀于一池,改变其运行程序不仅可去除有机物,还能达到脱氮除磷效果。 试验结果表明,工艺的运行周期为22h(其中进水1h,进水和厌氧搅拌6h,好氧14h,沉淀及排水各2h),进水COD浓度在1000—4000mg/L时,COD去除率为84％以上,最高达96％。另外,水文还分析了有机物的去除特点。

In this paper, the research was made on the treatment of paint wastewater by a sequencing biological batch reactor. The experimental results demonstrate that the biological batch system can effectively remove organic matter. With the experimental time sequence (flow-in 1 h. ,anaerobic 6 h. ,aerobic 14h. ,setting 1 h. and flow-out 1 h. ) ,the removal rate of COD is 84%-96% (influent COD is 1000-4000 mg/L).
