Experimental Study on Village Wastewater Based on ABR-MBBR Integrated Device
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.
