摘要
在印染废水的出水中投加白腐真菌和芽孢杆菌,探讨了停留时间和转速对深度处理过程中COD去除效果的影响。生物填料法处理结果表明:在停留时间为5 h、搅拌转速为150 r/min时,废水脱色率大于99%,COD由进水时的157.68 mg/L下降至45.67 mg/L。
Adding white rot fungi and bacillus in printing and dyeing wastewater, discusses the retention time and the effect of rotation speed on the removal effect of COD. Through the Biological packing method,the results showed that： in the retention time for 5 h, stirring speed is 150 r/min, the decolorization rate is more than 99 %, at first,the COD is 157.68 mg/L,after the treatment, it dropped to 45.67 mg/L.
