摘要
采用序列间歇式活性污泥法(Sequencing Batch Reactor Activated Sludge Process,SBR)法和共代谢理论,利用白腐真菌对含有木质素的造纸废水进行处理试验研究.结果表明,同样的进水COD浓度,水力停留时间,共代谢作用下好氧处理的COD去除率远高于单纯好氧生物处理COD去除率,可提高30%左右.原水的投加有一个恰当的比例,在根据实际用水水质选定碳源后,在碳源和氮磷营养物质的共同作用下,共代谢降解过程能得到明显的促进,其处理效果高于碳源和氮磷营养物质单独存在条件下的处理效果.
With SBR method and co-metabolis,the technological of paper making waster treatment by lignin fungi degradation were studied. The results showed that the aerobic treatment with co-metabolism had a better removel ratio of COD concentration of water intlow than simply aerobic treatment did on the same condition of COD concentration of water inflow and hydraulic residence time.The ratio will be improed by 30 % aroud. The concentration of origin water had a best propotion,with the quality of real waste water which can improve the course of co-metabolism degradation obviously. The processing effect is better than that on the conditon of carbon resource and nitrogen-phosphor nutriment existed singly.
