摘要
在造纸废水系统的二级处理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5h、搅拌转速为150r/min时,废水脱色率大于99%,COD由进水时的138.42mg/L下降至33.28mg/L。
A small scale test on the intensive treatment of paper mill effluent with biological stuffing process is introduced, The function of white rot fungi and bacilli in the waste water treatment was analyzed. The effect of HRT and rotating speed on COD removal in the treatment process was discussed. The decolor ratio after the treatment was greater than 99% and COD conformed to the discharge standard,
