Abstract

The invention discloses split aeration upflow sludge bed integrated sewage treatment equipment, which comprises an aeration tank, a biochemical reaction tank and a water collecting tank. Aeration in the aeration tank is power for sewage circulation of the equipment, and the aeration quantity determines the reflux quantity, the types of microorganisms in the biochemical reaction tank and the sewagetreatment effect. The biochemical reaction tank is a main place for microbial growth and pollutant treatment, sludge in the tank is layered by controlling the ascending flow rate and the dissolved oxygen in water, the lower layer is mainly aerobic granular sludge with good precipitation performance, and the upper layer is sludge with poor precipitation performance and attached with a large amountof denitrifying bacteria; nitrogen and organic matters are removed through aerobic microbial oxidation and anaerobic bacteria denitrification, and water flow is circulated for multiple times, so thatthe treatment effect of equipment is improved. Aerobic granular sludge culture and sewage treatment by utilizing aerobic granular sludge are realized by adopting a split aeration mode, and various types of sludge and reactions in a biochemical region coexist by controlling the aeration rate, so that efficient removal of pollutants is realized.

Description

technical field [0001] The present invention relates to a kind of sewage treatment equipment, more specifically, relates to a separate aeration upflow sludge bed integrated sewage treatment equipment. Background technique [0002] At present, the mainstream technology of sewage treatment is the traditional activated sludge method. This process realizes the removal of organic matter, nitrogen and phosphorus by using microbial nitrification and denitrification. With the development of the economy, the requirements for sewage treatment and the types of sewage continue to increase, and the shortcomings of traditional activated sludge, such as low impact load resistance and poor resistance to harmful substances, have begun to amplify. [0003] Aerobic granular sludge is a kind of activated sludge formed by self-coagulation of microorganisms under aerobic conditions. Compared with traditional activated sludge, it has higher microbial biomass, stronger activity, good settling perfo...
