Abstract
The utility model relates to an integrated denitrogenation and dephosphorization biological filter which belongs to the technical field of water treatment by taking the biological filter as a main body. A sewage treatment layer is composed of an anaerobic layer, a hypoxia layer and an aerobic layer, wherein the anaerobic layer is arranged on a supporting buffer layer; the hypoxia layer and the aerobic layer are orderly arranged on the anaerobic layer; baffles are arranged among the anaerobic layer, the hypoxia layer and the aerobic layer. A return pipe is arranged between the upper part of the aerobic layer and the lower part of the hypoxia layer; the lower part of the aerobic layer is provided with an aeration device which is connected with an aeration pump by an aeration pipe. The utility model changes the traditional structure provided with a single sewage treatment layer, combines the anaerobic layer, the hypoxia layer and the aerobic layer into the same reactor and integrates a nitration unit, a denitrification unit and a dephosphorization unit into the biological filter. The utility model has the advantages of high-efficiency denitrogenation and dephosphorization capability, shock and load resistance, stable running, few occupied land, low capital construction and running cost, simple and convenient management and operation, etc.
Description
(1) technical field
The utility model relates to a kind of integration denitrification and dephosphorization biological filter, belongs to the water treatment field technology based on the biological filter.
(2) background technology
Along with development of industry and agriculture, the dead front type waters eutrophication phenomenon that a large amount of high nitrogen and phosphorus content sewage emissions cause is on the rise.As traditional biological denitrification method, denitrification reaction generally need be through two bioprocesses: nitration reaction and denitrification process, the nitrification and denitrification reaction must independently be finished in the operating unit respectively.This technology relates to three lock out operation unit, two return-flow systems; For small scall scale city and industrial sewage, then too huge, complicated, floor space is big.At present some novel denitrification dephosphorization techniques are as appearance such as synchronous nitration and denitrifications, and these technology can be saved organic carbon source in a large number, save energy consumption, but that is that all right is ripe for these technology, applies also having difficulties.
The biological filter is a kind of traditional water treatment device, it is simple to have technology, floor space is little, the characteristics that capital construction and working cost are low, it is single anaerobic layer or single layer of oxygen deficient or single aerobic layer that but its sewage disposal layer is generally form, can not realize denitrogenation effectively, filling adsorption poor performance commonly used can't realize effective dephosphorization.
(3) summary of the invention
The integration denitrification and dephosphorization biological filter of advantages such as at the defective of prior art, the utility model provides a kind of high-efficient denitrification and dephosphorization ability that has, and anti-shock loading is stable, takes up an area of to lack, and capital construction and working cost are low, and bookkeeping is simple and convenient.
A kind of integration denitrification and dephosphorization biological filter, comprise water inlet pipe, rising pipe, support buffer layer and sewage disposal layer, the sewage disposal layer is made up of anaerobic layer, layer of oxygen deficient and aerobic layer, anaerobic layer is arranged on the support buffer layer, be layer of oxygen deficient and aerobic layer successively above the anaerobic layer, be respectively equipped with dividing plate between anaerobic layer, layer of oxygen deficient and the aerobic layer.
Aerobic layer top and and the layer of oxygen deficient bottom between be provided with return line.
The aerobic layer bottom is provided with an aerating apparatus, and this aerating apparatus is under the dividing plate between layer of oxygen deficient and the aerobic layer; This aerating apparatus is connected with aeration pump by aeration tube.
The utility model has changed traditional structure that single sewage disposal layer is set, melt anaerobic layer, layer of oxygen deficient and aerobic layer in same reactor, with nitrated unit, denitrification unit and dephosphorization unit are incorporated in the biological filter, the top of biological filter is aerobic layer, the middle part is a layer of oxygen deficient, and the bottom is an anaerobic layer.The filler of reactor is that shell or oyster shells etc. contain the cheap material that enriches calcium salt.Sewage is flowed into by the bottom, forms one section anaerobic layer; Water outlet is flowed out by top, is partly refluxed to the middle part, forms one section layer of oxygen deficient; The aerobic layer bottom is provided with aerating apparatus, the sewage anaerobic layer of flowing through successively, and layer of oxygen deficient and aerobic layer, filler and microorganism carry out double purified to sewage, finish to organism the removal of nitrogen and phosphorus.
The utlity model has the high-efficient denitrification and dephosphorization ability, anti-shock loading, stable, take up an area of few, advantage such as capital construction and working cost are low, and bookkeeping is simple and convenient.
