Summary description： Huairou District 2016 village level sewage treatment station upgrading project is mainly composed of pre-treatment structure regulating pool and core process ao-mbr integrated equipment. In order to solve the problems of energy consumption must be reduced to the minimum, the effluent quality is good, the operation effect is stable, the simplified management and the intensive equipment are needed for the decentralized sewage treatment. Based on the operation practice and theoretical innovation research for many years, Huayu brilliant further reduces the operation and maintenance cost and the higher discharge requirements of nitrogen and phosphorus The integrated equipment is suitable for 5-500 m3 / D decentralized sewage treatment. It has a series of advantages, such as good effluent effect, small floor area, basic consumption of excess activated sludge, long cleaning cycle of membrane on-line and off-line, simple operation and maintenance, and low operation cost. The effluent quality meets the comprehensive discharge standard of water pollutants (DB11 / 307-2013) of Beijing City, and reaches the village A-level emission standard. Therefore, the decentralized integrated wastewater treatment equipment has considerable advantages in terms of technology, economy, environmental benefits and convenience of follow-up government supervision.
