摘要
倒置A2/O悬浮填料生物膜处理工艺,能有效解决生物脱氮除磷工艺中的泥龄矛盾。其工艺简单、运行低耗、处理高效、抗冲击能力强的特点在宣汉采气作业区的生活污水处理工程中得以应用,适合油田作业区生活污水的处理。在来水波动较大时,出水也可达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准。
In Xuanhan gas field, the process of inverted A2/O & suspended carriers biofilm was used in a project with the characteristics of simple process, low energy consumption, high efficiency and strong impact resistance . It solved the sludge age problem in nitrogen and phosphorus removal. Even waste water quality ranges widely, the treated water can meet Category B ,Class 1 under the standard of 《Discharge standard of pollutants for municipal wastewater treatment plant》 (GB18918-2002).
