A2/O工艺法深化处理混合污水的试验研究

摘要

建立了A2/O工艺处理工业和生活的混合污水的工艺流程.试验结果表明,在系统稳定运行的情况下,可以初步达到对该混合污废水的去除,深化调节A2/O工艺中的C/N、C/P、缺氧好氧体积比等参数对污水中有机物的去除具有强化效果.尤其针对磷含量较高的污废水,通过控制C/P比在30左右能够达到高效除磷的效果.最终出水水质满足GB 18918-2002的一级B标准.%The A2/O process was used to treat the mixed wastewater of domestic sewage and industrial sewage.The result indicated that in the stable operating system,it could preliminarily remove the mixed waste water,and deepening the regulation of A2/O and C/N in C/P process,anoxic aerobic volume ratio on removal of organic matter in sewage has an strengthening effect.Especially for the high phosphorus content of wastewater,through the control of C/P ratio at about 30 to achieve the effect of efficient phosphorus removal,the effluent of the process could satisfactory go to grade B of national discharge standard of GB 18918-2002.
