Abstract
With the rapid development of village and town wastewater treatment at home,many wastewater treatment technologies have come into being.In this paper,an integrated wastewater device with ABR and secondary MBBR-fiber bundle membrane treatment technology has been innovated,which is mainly composed of ABR pool,secondary MBBR pool,vertical flow sedimentation tank and fiber vertical membrane pool.In the experiment,the effluent from a municipal wastewater treatment plant in Shanghai is simulated to simulate the effluent from a village.By studying the parameters of membrane acclimation,the treatment effect of the device is explored.The results show that the device has a certain impact load resistance to the fluctuation of influent quality,and through the adjustment of the indirect aeration process of MBBR tank.It can achieve a good effect of removing nitrogen and phosphorus.The removal rates of CODCr,ammonia nitrogen,TN,TP,SS and other indices of the equipment are stable at 86％,86％,46％,53％,above 85％.The effluent meets the class B standard of Shanghai municipal local standard Discharge Standard of Water Pollutants for Rural Sewage Treatment Facilities(DB 31/T 1163-2019),which has certain reference significance for the selection of rural waste water treatment technology at home.关键词
