Description
Technical field
The present invention relates to sewage treatment area, especially a kind of disk type multistage composite biological cleaning integrated technique, it enters one
Advanced nitrogen is walked, sewage Effluent criteria is improved to reach reuse requirement, while improving energy utilization rate, integrated technology unit is real
It is existing process intelligent, integrated.
Background technology
The regeneration of sewage is to increase income and decrease expenditure, mitigate water pollution, improve the ecological environment, solve the effective of urban water shortage
The potentiality of one of approach, wastewater treatment in China and reuse are huge, and exploitation Novel sewage regeneration technology has wide with method
Market prospects.
Add one kind that special disc is biomembrance process sewage disposal technology in traditional biological processing system, disc by
Mechanical rotation is alternately contacted with air, groove water, and the microbial film grown in disc surfaces creates aerobic, anoxia condition, repeatedly
Oxygen process in ground contact groove in dirty water and air is purified sewage.Also have using pneumatic disc, microbial metabolism institute
The dissolved oxygen needed is supplied by being located at the aeration tube on the downside of disc.Shearing stress is produced between film and card because of rotation, with film
Thickness increase and increase, to a certain extent, film comes off from card, is flowed away with water.Therefore set heavy as latter in the system
Shallow lake pond, outlet effect does not reach regeneration standard, and technique is scattered, takes up an area big.Traditional biological rotating disk has one to total nitrogen degradation
Fixed ability, but it is less efficient, and when dephosphorization requires high, it is difficult to meet.
To this bio-disc technique have similar structure filtering cloth filtering pool technique can as advanced treatment unit, mainly according to
Suspended impurity is retained by special filter-cloth filtering, it is adaptable to purifying again for Sewage Plant two-stage precipitation water outlet, have to influent quality index
It is required that, water inlet SS requirements are less than 30mg/L.Traditional filtering cloth filtering pool is main to remove in water removal SS as target.
The content of the invention
It is further advanced nitrogen, by force the present invention is more particularly directed to a kind of disk type multistage composite biological cleaning integrated technique
Phosphorus is eliminated, sewage Effluent criteria is improved to reach reuse requirement, while improving energy utilization rate, integrated technology unit realizes work
Skill is intelligent, integrated.
A kind of disk type multistage composite biological cleaning integrated technique involved in the present invention is made up of 3 modules：Step disk
Piece module（3 grades）, coarse filtration mud-water separation module, refined filtration phosphorous removal biochemical module.
Step disk module mainly rotates the biochemical treatment that the biomembrane to be formed realizes sewage using disc, is pollutant drop
The core cell of solution, traditional biological rotating disk drives disc rotation by solid shafting, and the present invention sets three-level gradually reducing pipeline to be used as disc
Supporter, current, which enter caliber after pipeline, to be reduced, and flow velocity increase during into I. one-level disc anoxic modules, is rotated in pipeline axle
In the case of, current are sprayed onto disc by the tapping hole designed on pipeline, increase contact effect.
It is divided into 3 grades according to disc and water contact portion ratio, rotating speed and current flow difference, respectively I. one-levels disc lacks
Oxygen module;II. two grades of disc anoxic modules;III. the aerobic module of three-level disc, wherein,

Nitrogen, phosphorus removal functional effect.Microorganism concn is high, and running efficiency of system is high, and the ability of anti-shock loading is strong.
In the process of running, the thickness of biomembrane is continuously increased, 1.5 ~ 5mm of biofilm thickness of disc surface growth, by
Shearing force can be produced in disc rotation, and due to the reduction of biomembrane aging adhesive force, biomembrane can be fallen off, and then new
Biomembrane starts growth again, and biomembrane constantly carries out succession of the old by the new while reduction organic matter.The biomembrane split away off can profit
Mud-water separation is carried out with coarse filtration mud-water separation module.
Coarse filtration mud-water separation module is on the basis of traditional filtering cloth filtering pool, to be improved, and selects special aperture filter cloth, micro-
5 ~ 20 μm of hole, carries out mud-water separation, sludge is discharged through sludge drainage system, after separation by the mud mixed liquid from biological disk module
Clear liquid is collected；The module sets dephosphorization agent dosing system, increases phosphorus removal functional, the clear liquid being collected and dephosphorization agent through two-stage gradually
After the mixing of contracting tube mixer, into refined filtration phosphorous removal biochemical module, further filtering improves effluent quality.
Refined filtration phosphorous removal biochemical module is that the interception capacity of filter cloth is improved on the basis of traditional filtering cloth filtering pool, is selected smaller
The filter cloth in aperture, general aperture can be with 0.5 ~ 10 μm, and the water after filter SS reductions after coarse filtration are not adding the condition of dephosphorization agent
Under, SS is less than 20mg/L, and water outlet SS is smaller than 5mg/L after refined filtration;If the last stage adds dephosphorization agent, refined filtration process is main
Coagulation flco is separated from water, fine dephosphorization is realized in precipitation discharge.

Also there is good clean-up effect, such as slaughtering wastewater, beer waste water.
2nd, disc classification is set, biofacies classification, increases bio-diversity, is conducive to microbial reproduction and organic matter to drop
Solution, while strengthening nitrification, phosphorus removal functional.
3rd, disc material light weight, corrosion-resistant, hard and be unlikely to deform, specific surface area is big, and microorganism concn is high, system operation
Efficiency high, the ability of anti-shock loading is strong.
4th, lness ratio of plant is low, and general assembly acc power is low；Simple and compact device, auxiliary device is few, the throwing of whole filtration system
Money is low and takes up an area small.
5th, coarse filtration and refined filtration two-stage series connection, effluent quality are improved, high treating effect.
6th, device can realize modularization, suitable for decentralized sewage disposal, can be needed and operating load according to building, appropriateness is adjusted
It is whole, flexible configuration；
7th, compartmentalization automatic control supervision is easily achieved, operation maintenance is simple and convenient.
