A-B工艺处理以高浓度有机废水为主的城市污水

USING A-B PROCESS TO TREAT URBAN SEWAGE WITH HIGH CONCENTRATION ORGANIC WASTEWATER AS THE DOMINANT

A B工艺的进水主要以高浓度有机废水为主 ,溶解性的CODCr成分高且难以生物降解 ,高有机负荷和极端pH的冲击经常发生。根据进水水质的特点并结合A B工艺独特的优越性 ,合理地控制A段的运行参数 ,最大限度地挖掘A B工艺的潜力 ,保证A段的处理效果和出水的稳定性 ,为B段稳定运行创造好的条件。

The influent of A-B process is a sewage with high concentration organic wastewater as the dominant,whose dissolved COD Cr is very high and non-degradable.Therefore,high organic loading and impact of extreme pH occur frequently.The running parameters for section A are controlled rationally,and the potential of A-B process is exploited to its maximum according to the character of the influent and the superiority of A-B process,which can guarantee the treating effect and effluent stability of section A,thus creating good conditions for the stable running of section B.
