摘要
为了解AMBBR一体化装置处理农村生活污水启动调试过程中脱氮除磷特性,以贵州兴仁周边农村生活污水为处理对象,采用接种闷曝法进行挂膜,研究该装置调试过程中水质变化。同时,将间歇曝气与连续曝气处理效果进行比较,分析设备运行过程中出现的问题并提出相应解决办法。由连续运行检测数据可知,农村生活污水经设备处理后COD、NH_(3)-N、TN和TP分别可以稳定到40、7、10、0.54 mg/L左右。连续曝气和间歇曝气对COD和TP的处理效率影响不大,但对于TN及NH_(3)-N有着显著影响,连续曝气的效果明显高于间歇曝气,闷曝培养后,TN和NH_(3)-N处理能力仅比连续曝气效果略低。
In order to understand the characteristics of nitrogen and phosphorus removal in the commissioning process of AMBBR integrated unit for rural domestic sewage treatment.The rural domestic sewage from Xingren,Guizhou province was taken as the treatment object,and the film was hung by inoculation and smothering aeration method.The water quality changes in the commissioning process of the unit were studied,and the effects of intermittent aeration and continuous aeration treatment were compared.The problems in the equipment operation are analyzed and the solutions are put forward.According to continuous operation detection data,with the average effluent concentration of COD,NH_(3)-N,TN and TP were 40,7,10 and 0.54 mg/L,respectively.Continuous aeration and intermittent aeration have little effect on the treatment efficiency of COD and TP,but have significant effect on TN and NH_(3)-N.The effect of continuous aeration is obviously higher than that of intermittent aeration.After the cultivation of stuffy aeration,the treatment capacity of TN and NH_(3)-N is only slightly lower than that of continuous aeration.
