Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0035] figure 1 A schematic diagram showing the structure of an anaerobic microporous aerated oxidation ditch reactor according to an embodiment of the present invention.

[0036] Such as figure 1As shown, the anaerobic microporous aerated oxidation ditch reactor in this implementation includes a plurality of treatment areas that are adjacent to each other and hydraulically connected to each other. The plurality of treatment zones include a hydrolysis zone 1 , an anaerobic zone 2 , an anoxic zone 3 , an aerobic zone 4 , a sedimentation zone 5 and a sludge storage tank 6 . The above multiple processing areas are rationally arranged to form a total area of ​​the reactor which is similar to a rectangle and surrounded by the outer walls W1-W4 of the reactor. In this embodiment, the outer wall W1 of the reactor near the anaerobic zone 2 and the anoxic zone 3 is ...

Abstract

The invention discloses an anaerobic microporous aerator oxidation ditch reactor and a sewage treatment method. The reactor comprises a plurality of treatment zones which are adjacent to and communicated with one another hydraulically, wherein the treatment zones comprise a hydrolysis zone, an anaerobic zone, an anoxic zone, an aerobic zone and a settling zone. Supernate return channels are formed between the settling zone and the hydrolysis zone for returning nitrate-containing supernate from the settling zone to the hydrolysis zone, and denitrification treatment is performed by using the action of denitrifying bacteria. The reactor integrates hydrolysis, anaerobic treatment, anoxic treatment, aerobic treatment and settling, thereby greatly saving floor area and reducing investment cost of infrastructure construction. The adopted internal and external return systems improve the utilization rate of the capacity of a pool, increase denitriding and dephosphorizing effects and reduce treatment cost.

Description

technical field [0001] The invention relates to a facility and method for treating urban domestic sewage, in particular to an anaerobic microporous aeration oxidation ditch reactor for meeting the requirements of deep denitrification and phosphorus removal and a method for sewage treatment using the reactor . Background technique [0002] In order to protect the water environment and reduce pollution, my country has increased the construction of urban sewage treatment plants in recent years. At present, the processes suitable for urban sewage treatment include mainstream technologies such as activated sludge process, SBR process and its variants, and oxidation ditch process. However, urban sewage treatment is also one of the industries with high energy consumption. High energy consumption leads to high operating costs of sewage treatment facilities, which is one of the important reasons for the failure of sewage treatment plants to operate normally. Therefore, the energy s...
