Description
Technical field
The present invention relates to technical field of sewage, be specifically related to a kind of novel carriers biological rotating disk and process the side of sewage
Method.
Background technology
The critical period that China is in economic development and living standards of the people step up now, and along with urban human
Mouthful increase and the development of industrial and agricultural production, in social production, life process produced sewage the most increasing and also due to existing
Modern industrial and agricultural production quickly grows, and in sewage, various chemical elements and microorganism are consequently increased, existing biochemical treatment sewage
Though system can reach the water quality requirement of discharge water, but along with the raising of environmental requirement, still needs to add existing sewage disposal system
To improve, to further enhance its wastewater treatment efficiency, improve the standard of effluent quality, be badly in need of one the most now and can reduce dirt
Various microorganisms and the sewage disposal system using biochemical method of chemical element in water, thus reduce sewage to natural ring
The harm in border.
Biological rotating disk is the Sewage Biological Treatment equipment occurred in the sixties in last century, is that a kind of biomembrance process waste water processes
Technology, bio-disc can have stronger anti impulsion load ability with the longer microorganism of apposition growth generation cycle, process effect
The best.In terms of process operation and maintenance, biological rotating disk has without sludge reflux, does not has filamentary discharges phenomenon, and power disappears
Consume the advantages such as low, operating cost is low.But traditional biological rotating disk exists in sewage disposal process, and organic loading is low, sanitary condition
The problems such as difference, denitrification effect are bad.Biological rotating disk technique is the artificial-strengthening of sewage irrigation and land treatment systems, and this facture makes
Antibacterial and the microorganism of mushroom, microfauna growth reproduction on biological rotating disk filling carrier of protozoacide one class, form film
Shape biological sludge organism film.Sewage after sedimentation tank primary treatment with biofilm contact, microorganism panning on biomembrane is dirty
Organic pollution in water, as nutrition, makes sewage be purified.Dissolving in pneumatic biological rotating disk, needed for microbial metabolism
Oxygen supplies by being located at the aeration tube on the downside of biological rotating disk.Disc surfaces is covered with airhood, the compression discharged from aeration tube
Air drives airhood to make rotating disk rotate, and when rotating disk leaves sewage, disc surfaces forms the water layer of thin layer, and water layer is also
Dissolved oxygen is absorbed from air.
Summary of the invention
The technical problem to be solved in the present invention is to provide the novel carriers biological rotating disk that a kind of method is simple, efficiency is high and processes
The method of sewage.
For solving the problems referred to above, the technical solution used in the present invention is:
A kind of novel carriers biological rotating disk processes the method for sewage: sewage is passed into preliminary sedimentation tank by water inlet by (1),
Then add flocculant in the ratio of 1L sewage 30g flocculant, make in waste water under the sedimentation of most suspended substances and inorganic particulate matter
Come；(2) sewage processed is passed in nanometer aeration device at a temperature of 100～150 DEG C, sewage is carried out nanometer exposure
Gas disposal 24～36h, prevents free state microorganism from competing organic nutriment with microorganism on filler；(3) sewage is passed through biological turning
Dish integrated apparatus, rotating disk has the card of 50% to immerse in sewage, along with the rotation of rotating disk, the carrier microorganisms of load on rotating disk
With the Organic substance in sewage and inorganic matter as nutrition, self-reproduction and on rotating disk biofilm form biomembrane, to the dirt in sewage
Dye thing carries out absorbing and filtering process；(4) sewage after being processed by biological rotating disk integrated apparatus is flowed into containing turbo-two
In secondary sedimentation tank, being then passed through ozone under ultraviolet intense irradiation, under the effect of turbine, ozone is fully contacted with sewage, carries out
Discharge after sterilization treatment.
Further, described preliminary sedimentation tank is provided with mobilizable swash plate grid, between described adjacent two grids
Distance be 4mm, grid can extract to clear up the mud being difficult to landing of institute's appendix at any time.Grid is set and can promote the heavy of mud
Fall, reduces the sedimentation problem slowly caused due to current.
Further, described flocculant be styrene sulfonate, ligninsulfonate, acrylic acid, methacrylic acid mixed
Compound.Mixed proportion is volume ratio: 1:1:1:1.Flocculant hydrolysis rate is fast, and high adsorption capacity can settle rapidly in sewage
Float and particles of inorganic material.
Further, described carrier microorganisms has the polymerization of ammonifiers, Nitrosomas, Nitromonas, sulfur bacteria, polyP bacteria
Strain.Carrier microorganisms can utilize the nutrition that the Organic substance in sewage is bred as own growth, can be decomposed by pollutant simultaneously
It is oxidized to the material of safety non-pollution.
Further, the intensity of described ultraviolet is 200uW/cm, and the intake of ozone is 0.1～0.5ml/h.Ultraviolet
Line and ozone carry out sterilization treatment to sewage, prevent that content of microorganisms in sewage is too high causes biological pollution of water body.
Further, described biological rotating disk is to be run through by 100～150 sheet glass steel disk thread spindles, lies in one
On the groove face of the bar-shaped trough of individual section semicircular in shape, the dish footpath of disk is 3～3.5m, and the diameter of bar-shaped trough relatively disk diameter is slightly
Greatly, the rotating speed of rotating disk is 2～3r/min, and along with disk is around the rotation of thread spindle, fiberglass disk foremost is by thread spindle
On forward biological demoulding groove to, continue around thread spindle from the other end of thread spindle after biofilm detachment and rotate, move in circles.
Beneficial effects of the present invention is embodied in: the present invention utilizes a kind of method that novel carrier organism rotating disk processes sewage
Simple to operate, the efficiency removing pollutant is high, does not results in the pollution again of sewage simultaneously, and low cost, high financial profit.
