Abstract

Abstract: Aiming at the demand of decentralized domestic sewage treatment in rural areas, Sequencing Batch Airlift Reactor (SBAR) for domestic sewage treatment was developed and applied for sewage disposal of an office building in shenjiadun village, Deqing, Zhejiang Province. The device doesn't need to set up sedimentation tank and sludge reflux system. It has a good precipitation effect and only occupies a small area. In the aspect of control, it adopts the self-researched embedded software system. And it integrates GPRS/GSM/SMS/CDMA/Internet communication technology and high-precision electrical parameter measurement technology. The actual operation results show that the device can ensure sufficient contact between sludge and waste water. It can effectively remove BOD5, CODCr, ammonia nitrogen and total nitrogen from domestic sewage. And it has the advantages of low investment, low energy consumption, high automation and simple operation. Therefore, this device has important popularization value in the field of distributed treatment of rural domestic sewage.
