摘要
介绍了粉末活性炭及生物铁复合法在含氰废水处理中的应用情况，通过工业放大实验证明，复合法能大幅度提高污水ＣＯＤ、ＢＯＤ的去除率，并能有效地防止由于水力负荷和有机负荷造成的冲击，即使对ｐＨ、温度、毒物等造成的冲击，采用复合法后，系统的恢复时间也较纯活性污泥法缩短了７ｄ左右，经经济核算，认为含氰废水采用复合法处理是可行的。
In this paper, application of PAC and biological ferrous salt compound activated sludge process to the treatment of cyanic wastewater was introduced. It was proved by amplified industrial tests that the removal rate of COD and BOD could be greatly raised and the impact caused by hydraulic or organic loading could be effectively prevented after this compound process came into use on the treatment of cyanic wastewater. Even for the impact caused by PH, temperature or toxicants, the recovery cycle for this compound process was reduced by about seven days less than that of the pure activatfed sludge process. Economic accounting showed that this compound process is practicable for the treament of cyanic wastewater.
