Abstract

The invention relates to a sewage treatment area for a vertical multistage AO ecological sewage treatment tank. The treatment area is composed of a sludge layer, an anaerobic layer, an anoxic layer and an aerobic layer which are successively superimposed from bottom to top. The inside of the treatment area is divided by crisscrossed separator plates into a plurality of septal areas. The tops of the separator plates are positioned at the junction of the aerobic layer and the anoxic layer. The top of each separator plate is covered with a ballast plate. Each ballast plate is provided with at least a through hole. The structure setting of the ballast plates provides a certain resistance for upflowing sewage. Thus, convection current of sewage is formed between the anaerobic layer and the anoxic layer, time for anaerobic degradation of sewage at the anaerobic layer and time for denitrification reaction of sewage at the anoxic layer are prolonged, and anaerobic degradation and denitrification of sewage are more complete. With the arrangement of the through holes in the ballast plates, sewage can be dispersed rapidly so as to raise aerobic degradation and nitration efficiency of an organic matter, reduce load of subsequent sewage treatment processes and enhance the overall sewage treatment efficiency and quality.

Description

For the sewage diposal area in vertical multistage AO ecological sewage treatment pond
Technical field
The present invention relates to a kind of Sewage water treatment zone for the treatment of tank, refer to a kind of sewage diposal area for vertical multistage AO ecological sewage treatment pond especially.
Background technology
The main body structures in vertical multistage AO ecological sewage treatment pond are the ponds that a depth of water is greater than 6 meters.Its main body is formed by stacking by sludge stabilization and storage area, anaerobic layer, layer of oxygen deficient, aerobic zone, plant growing district etc. vertical (from bottom to top).It is an artificial ecosystem be made up of biological (as: bacterium, algae, protozoon, metazoan, waterplant, high hydrocoles) and abiotic (illumination, wind, temperature, organism, pH value, dissolved oxygen, N and P nutritive element etc.) part.
The top of each septal area of the sewage diposal area in existing vertical multistage AO ecological sewage treatment pond is uncovered structure, the sewage upwards flowed by bottom directly can flow to aerobic zone by layer of oxygen deficient, the time that sewage stops in anaerobic layer and layer of oxygen deficient is relatively short, the anaerobic degradation of sewage in anaerobic layer and the anti-nitration reaction time at layer of oxygen deficient short, if wastewater influent flow is large, then easily react incomplete situation, and then affect the treatment effect of sewage.For this reason, the flooding velocity of the sewage diposal area in existing vertical multistage AO ecological sewage treatment pond needs the degree of depth being restricted or needing greatly to increase water-in, and the sewage treatment capacity for the treatment of tank is limited or laid down cost is higher.
Summary of the invention
The invention provides a kind of sewage diposal area for vertical multistage AO ecological sewage treatment pond, to overcome the problem that sewage treatment capacity is limited or laid down cost is higher of the treatment tank that existing sewage diposal area exists.
The present invention adopts following technical scheme:
For the sewage diposal area in vertical multistage AO ecological sewage treatment pond, treatment zone is made up of sludge blanket superimposed successively from bottom to top, anaerobic layer, layer of oxygen deficient and aerobic layer, form a plurality of septal area by crisscross baffle for separating in treatment zone, dividing plate top is positioned at the intersection of described aerobic layer and layer of oxygen deficient; Each septal area top cover is provided with ballast plate, and each ballast plate is equipped with at least one through hole.
Further:
Each above-mentioned through hole is up big and down small taper hole shape.Configuration thing on through hole following two kinds: one is preferably that each above-mentioned through hole has all set up a baffle, and this baffle is is integrally connected and composed by tip two cone-shaped bodys upward and down, and the lower cone wall of baffle is roughly the same with the gradient of through hole hole wall; Baffle can be hollow structure, and baffle mounted inside has aerobic filler and/or oxygen-starved filler, and baffle is also equipped with the aerated conduit for connecting steam line and forms aeration structure.Further, the lower cone wall of baffle and/or through hole hole wall are provided with spiral salient or spiral groove.Two are, are configured with the aerating apparatus of prior art routine above each above-mentioned through hole, and this aerating apparatus is assemblied in above-mentioned ballast plate.
Above-mentioned treatment zone is equipped with water inlet system, a plurality of subtubes that this water inlet system comprises main pipeline and is communicated with main pipeline, the end that this main pipeline is connected with this subtube is embedded in the below for the treatment of tank, and the top also extending to sludge blanket at the bottom for the treatment of tank pond is straight up run through in the upper end of subtube.
In addition, each septal area is all configured with at least one above-mentioned subtube.Further, each septal area is configured with an above-mentioned subtube respectively, and subtube is located at Chi Di center, septal area, and the water outlet of subtube is opened on the sidewall of subtube top, and such vibrational power flow is conducive to the even diffusion of sewage.In addition, each subtube is all configured with a motorized valve and a magnetic flow meter, to realize Automated condtrol wastewater influent amount.
From the above-mentioned description to structure of the present invention, compared to the prior art, tool of the present invention has the following advantages: the resistance that the vibrational power flow of ballast plate of the present invention gives the sewage manufacture of upwards flowing certain, sewage is made to form convection current between anaerobic layer and layer of oxygen deficient, thus extend the anaerobic degradation time of sewage in anaerobic layer and the anti-nitration reaction time at layer of oxygen deficient, make anerobic sowage degrade and denitrification more complete, the COD clearance of sewage improves 30 ~ 40%, and the clearance of total nitrogen improves 25 ~ 45%; And the through-hole structure on ballast plate is arranged, make sewage can rapid diffusion in aerobic layer, thus improve organism aerobic degradation, nitrated efficiency, and then effectively improve the wastewater treatment efficiency of single AAO process, reduce the load of follow-up sewage disposal operation, improve the efficiency of overall sewage disposal.
In addition, the pipeline major part of sewage diposal area of the present invention is embedded in underground, neither takies the space of sewage purification reaction; also the protection of pipeline is conducive to; make pipeline not subject to outside destroy, reduce pipeline and to be corroded rotten degree, thus effectively extend the work-ing life of pipeline.And the roughly constant temperature of underground makes sewage enter before in treatment tank pond can be adjusted, make it roughly the same with the water temperature in pond, be conducive to sewage to react efficiently in pond, also be conducive to keeping the constant of pool inner water temperature, and then the stable living environment of the ecosystem in guarantee pond, also ensure that the purification efficiency of sewage.
