Description

A kind of sewage disposal system with except grease function

Technical field

It is especially a kind of for handling the molten gas system of grease type pollution the utility model relates to a kind of sewage disposal system System.

Background technique

In water treatment field, the oil or lightweight suspension object in airfloat equipment separation water are generallyd use.Airfloat equipment work It is in advance under high pressure to dissolve in air in recirculation water as principle, forms oversaturated high-pressure air-water mixture, then by this air water Mixture is discharged into water by release decompression, generates a large amount of micro-bubbles, these micro-bubbles stick oil in water or Lightweight suspension object, is carried and is climbed up on top of the water, and dross is scraped airfloat equipment using Slag Scraping Device, thus by oil or lightweight suspension Object is separated off from sewage.

Sewage is generally directly directly entered dissolving, the mixing of water and gas by existing air dissolving system after high-pressure pump pressurizes Fluidised form is poor, it is difficult to guarantee that gas-liquid comes into full contact with, therefore the molten tolerance in dissolved air water is relatively low, air flotation effect is poor；In addition contain in sewage There is a large amount of lint shape grease and other impurity to enter aeration tube, be easy to cause the blocking of aeration tube tube body and dissolving, influences Molten makings amount, air flotation effect are poor.

Summary of the invention

The utility model provides a kind of air dissolving system with good processing grease type pollution.

It is a kind of to be divided into the sewage disposal system for removing grease function, including coarse filtration tank, the coarse filtration tank by partition Left lautertuns and right lautertuns are provided with the filtering dictyosome that may filter that large-scale dregs, the filtering dictyosome in the left lautertuns Lower end be equipped with grease filtrating dictyosome, filtering is grease separated space between dictyosome and grease filtrating dictyosome, the first separation pump one End is connect with grease separated space, and the other end is connect with fermentor, and right lautertuns is connect by the first outlet pipe with gas-floating chamber.

The partition lower end is equipped with agitating device, and holding vessel is equipped in the grease separated space, is set on the coarse filtration tank There is the second separation pump, one end of the second separation pump is connect with left lautertuns, and the other end is connect with right lautertuns, the right mistake Filter pocket is connect by the first outlet pipe with dissolving, and dissolving is connect by the second outlet pipe with gas-floating chamber, in the dissolving Equipped with dissolution gauze pad, the end of second outlet pipe is equipped with release, and the coarse filtration tank is installed on the ground by bracket, institute It states and is equipped with gate between the first outlet pipe and dissolving.

It is described in the utility model a kind of with the sewage disposal system for removing grease function, the beneficial effect is that:

(1) the lint shape grease and other impurity in sewage can be removed by being filtered for multiple times, keeps fluid unimpeded, mentions High sewage treating efficiency；

(2) it is provided with partition, is reduced as far as much as possible separating grease and sewage while oscillation；

(3) the dissolution gauze pad in dissolving is solid reticulate structure, and high-speed gas-liquid mixture carries out in dissolution gauze pad Multiple impact promotes gas-liquid sufficiently fused, provides molten tolerance, improve daf efficiency, has good removal grease effect；

(4) it is unimpeded to be able to maintain fluid for agitating device, improves molten gas efficiency and molten tolerance is high, and air flotation effect is good, has good Removal grease effect.
