Description
Technical field
The utility model relates to technical field of sewage, particularly relates to a kind of sewage filter device.
Background technology
Sewage water treatment method under prior art mainly contains following several:
1, dirty facility is blocked
In the former water of this engineering, solid impurity content is higher, for guaranteeing that the equipment such as lift pump normally work and ensure that subsequent disposal structures normally run, intends arranging at the leading portion of process main process blocking dirty facility.
2, carry out a biological disposal upon
Common sewage works generally adopts following several bioremediation.
A) biological contact oxidation process
Biological contact oxidation process belongs to biomembrance process, has the following advantages and feature:
1) in biological contact oxidation process biological tank, filler is set, because the specific surface area of filler is large, in pond, aerobic condition is good, and in biological contact oxidation pond, the biomass of unit volume is all higher than activated sludge process aeration tank and biological filter, and therefore biological contact oxidation pond has higher volumetric loading;
2) because quite a few microorganism set growth is at filling surface, biological contact oxidation process can not establish sludge recirculation system, also there is not sludge bulking problem, and operational management is convenient;
3) because biosolids amount in biological contact oxidation pond is many, current belong to complete mixed type, and therefore the cataclysm of biological contact oxidation pond to water quality and quantity has stronger adaptive faculty;
4) because biosolids amount in biological contact oxidation pond is many, when organism volumetric loading is higher, its F/M (F is organic radical quality, and M is microbial biomass) is than remaining on certain level, and therefore sludge yield can be equivalent to or lower than activated sludge process;
5) because loading filler, biological contact oxidation pond unit manufacturing cost is slightly high, is generally applicable to middle-size and small-size (Qd≤2500m3/d) sewage works.
B) conventional activated sludge method
Activated sludge process is a kind of most widely used waste water aerobic biologic treating technique in big-and-middle-sized sewage disposal.The primary condition that active sludge processing system effectively runs and feature are:
1) should have the easy degradation material of enough solubilities in waste water, as the nutrition that microbial physiology is movable required, general activated sludge process regularly must add nutritive substance according to a certain ratio, which increases working cost and management difficulty;
2) mixed solution must containing enough dissolved oxygens, and activated sludge tank is long aerobic protozoon, and the demand of oxygen is larger;
3) active sludge is suspended state pond planted agent, can fully contact with water and mix;
4) active sludge continuous backflow, gets rid of excess sludge in time, makes the activated sludge concentration that mixed solution keeps certain;
5) the Activated Sludge Growth cycle is long, poor to the cataclysm adaptive faculty of temperature, water quality and the water yield;
6) within should safe level being strict controlled in the virulent material of microorganism;
7) Wastewater Treated by Activated Sludge Process meets lower, and cause the volume of facility to increase, construction investment is corresponding increase also.
Just because of have above prerequisite and feature, so activated sludge process operational management is more professional.Activated sludge process easily produces sludge bulking in addition, and processing load is lower, wayward management, therefore use in recent years in middle-size and small-size sewage works is fewer and feweri.
C) SBR method
SBR method is a kind of comparatively advanced activated sludge method that developed recently gets up, and this treatment process integrates aeration tank, settling tank, continuum micromeehanics, intermittent aeration, settlement of sewage when stopping the supple of gas or steam, and skim supernatant liquor, becomes one-period, goes round and begins again.SBR method does not establish settling tank, and without sludge reflux equipment, but SBR method is gap operation, need establish multiple processing unit, and water inlet and aeration switch mutually, cause control comparatively complicated.In order to ensure weir loading, SBR method requires high to water decanter device fabrication, must keep on improving, otherwise very easily cause final outflow water water quality not up to standard during making.Domestic also do not have quality to strain wetting system preferably at present, import equipment buying trouble, and expensive, and maintenance cost is also high from now on simultaneously.In SBR method pond, sludge concentration is measured by concentration meter to control to discharge unnecessary sludge quantity, and current domestic concentration meter quality does not pass a test, and causes mud discharging to control more difficult.
SBR pond weir loading low (being generally no more than 40%), facility volume is comparatively large, causes construction investment higher.Owing to there are the technical matters that superelevation must be higher, activated sludge tank and SBR pond generally can only outdoor layouts, such local influence environment aesthetic feeling while arranging (buried construction investment will greatly increase).Contact oxidation technology each pond body can adopt buried setting, and equipment can arrange road or green belt, and general arrangement is elegant in appearance.Traditional biological contact oxidation process comprises grating tank, equalizing tank, biochemistry pool, settling tank, sterilization pool, sludge thickener, oxygen replenishing equipment and air-lift device.Wherein, grating tank is used for being separated the solid refuse in sewage.But under prior art, sewage is through grating tank, and solid refuse is easy to bring into transport unit inside, blocks transport unit, causes transport unit cisco unity malfunction.Meanwhile, also filtration efficiency can be affected.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of and filters the sewage filter device abundant, filtration efficiency is high.
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of sewage filter device, comprises grating tank, grid, transport unit, handgrip, seal strip and garbage cleaning device.Described grid is arranged in described grating tank, and the initiating terminal of described transport unit is arranged on the water outlet of described grating tank.The delivery direction that described handgrip is parallel to described transport unit is successively set on described transport unit.Gap between described transport unit and described grating tank is covered by described seal strip, and described garbage cleaning device is arranged on the end of described transport unit.
Preferably: described handgrip comprises connecting rod and drag head, described connecting rod is fixed on described transport unit, and described connecting rod and described drag head adopt and removably connect.
Preferably: described connecting rod offers groove, be provided with internal thread in described groove, the coupling end of described drag head is provided with the outside screw suitable with the internal thread in described groove.
