一体化生物处理反应器处理农村生活污水研究概况

Overview of Researches on Integrated Bio-treatment Reactors for Rural Domestic Wastewater Treatment

农村生活污水具有不同于城镇生活污水的特点,主要表现为排放点分散、有机物和氮磷含量高和水质水量波动大。一体化生物处理反应器处理农村生活污水的研究包括2个方面,即传统的单一工艺的一体化生物处理反应器,如SBR反应器、一体化OCO反应器、一体式膜生物反应器等;各种工艺组合的一体化生物处理反应器,包括活性污泥法与厌氧/缺氧工艺的结合、生物膜法与厌氧/缺氧工艺的结合。建议应结合农村地区的实际情况选择合适的一体化生物处理反应器。

The characteristics of rural domestic wastewater are different from those of municipal domestic sewage. They mainly include the decentralized discharge points, the high content of organic pollutants, nitrogen and phosphorus and the high fluctuation of water quality and quantity. There are two parts of researches on Integrated Bio-treatment Reactors { IBRs } for rural domestic wastewater treatment. The first part includes IBRs with the traditional single process, such as the SBR Reactor, the Integrated OCO Reactor, the Integrated Membrane Reactor and so on. The second part includes IBRs with combination process, sunch as the combination of activated sludge and A/A process, the combination of biofilm and A/A process. It was suggested that the proper IBRs should be selected according to the actual situation of rural area.
