Embodiment Construction

[0024] The sewage treatment device for efficient denitrification and dephosphorization provided by the present invention mainly includes:

[0025] The internal electrolytic anaerobic biological iron-carbon reaction pool 3 and the internal electrolytic anoxic biological iron-carbon reaction pool 4 form the internal electrolytic anaerobic-anoxic biological iron-carbon reaction pool. The pools are hung with Φ120 and L1200 combined elastic fillers, and the bottom of the pool is filled There are iron fillers and biochar fillers 7, wherein iron fillers are calculated at 30kg / kg COD, and biochar fillers are calculated at 40kg / kg COD. The internal electrolytic anoxic bio-iron-coke reaction pool 4 is connected to the bio-char retention pool 5, and the bio-char retention pool 5 is provided with a sludge pump 10 to pump the mud to the pump port so as to be sent into the interior electrolysis anaerobic bio-iron-coke reaction pool 3 and Recycling in the internal electrolysis anoxic bio-iro...

Abstract

The invention discloses a nitrogen and phosphorus removal sewage treatment device which mainly comprises a deodorization device, an internal electrolysis anaerobic-anoxic biological iron-carbon reaction tank, a flexible biological membrane contact oxidation filter tank, a sedimentation tank and an air blower room. The device disclosed by the invention can realize the functions of efficiently removing organisms, removing nitrogen and phosphorus and decomposing to remove animal and plant oils at the same time mainly according to the A<2> / O technology and by organically combining anaerobic, anoxic and aerobic three different environmental conditions and different types of microbial flora and by combining the advantages of iron-carbon filtration and biological iron process two wastewater treatment methods. The device disclosed by the invention can be widely applied to the treatment of various kinds of high-concentration organic sewage, and has the characteristics of simple technological flow, stable operation, high nitrogen and phosphorus removal rate, investment saving, low operation cost and the like.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage treatment device for high-efficiency denitrification and phosphorus removal, which is especially suitable for the treatment of high-concentration organic waste water. Background technique [0002] In the wastewater treatment process, the biological treatment method is considered to be the most economical and effective method, and is widely used in the treatment of industrial organic wastewater and urban domestic sewage. A 2 The / O treatment process is a typical representative of biological treatment. A 2 The / O treatment process is an organic combination of three different environmental conditions: anaerobic, anoxic, and aerobic, and different types of microbial flora. It can simultaneously remove organic matter, nitrogen and phosphorus, and has high pollutant removal efficiency. It is stable and has the advantages of good impact load resistance. However, ...
