According to the sewage treatment system, degreasing and phosphating sewage is treated and is charged on a discharge standard; meanwhile, the sewage treatment system is convenient to operate and manage, stable in performance, reliable and long in service life.
Description
[technical field]
The utility model relates to the technical field of sewage disposal, particularly the technical field of defatting-bonderizing Sewage treatment systems.
[background technology]
Phosphoric acid salt is easy to by plant utilization, and is converted into protein by photosynthesis, so can not find the phosphorus of high density in natural representative water.
With regard to present circumstances, in water body, the phosphorus of high-content mainly causes because untreated phosphorus-containing wastewater is directly discharged into occurring in nature.A large amount of discharges of phosphorous municipal effluent and trade effluent; to environment; especially the phosphorus composition in waste water can accelerate algal grown in water; consume oxygen in water, cause water body oxygen enrichment, water-quality guideline worsens; in view of the harm of phosphorus; China classifies phosphorus as two classes as and pollutes and control discharges, therefore how effectively to remove phosphorus in waste water to decontamination protection of the environment, is of great significance.
Lipid material is the important component of organic contamination in waste water, containing lipid waste water complicated component, contain a large amount of lipid acid, glycerine, surfactant, greases etc. present good emulsifying and affinity, can cause on a small quantity the COD of water body, BOD raises rapidly, more aggravate intractability, enter simultaneously city sewage work containing the middle longer chain fatty acid in Phosphorus organic waste water, oily substance is wrapped in the outer mass transfer that hinders oxygen of filler, if the unprocessed rivers,lakes and seas water body that directly enters of this class material, to endanger water ecosystem, severe contamination surrounding environment.
But also there is no at present the special Sewage treatment systems for processing degreasing sewage and phosphorization sewage and mix.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of defatting-bonderizing Sewage treatment systems, can process the sewage that degreasing sewage and phosphorus sewage mix.
For achieving the above object, the utility model proposes a kind of defatting-bonderizing Sewage treatment systems, comprise comprehensive wastewater pond, one-level settling tank, second-level settling pond, biochemical reaction tank, second pond, sludge thickener and pressure filter, described comprehensive wastewater pond, one-level settling tank, second-level settling pond, biochemical reaction tank is connected from front to back successively with second pond, the sludge outlet of described one-level settling tank connects sludge thickener, the outlet of described sludge thickener connects pressure filter, the sludge outlet of described second pond connects biochemical reaction tank, the sludge outlet of described biochemical reaction tank connects sludge thickener.
As preferably, described pressure filter adopts Car formula automatic pressure filter.
As preferably, described sludge thickener adopts vertical-flow concentration basin.
The beneficial effects of the utility model: discharge after defatting-bonderizing sewage disposal is reached effluent standard by the utility model.Also there is convenient operation and management simultaneously, stable performance, reliable, the advantage that the life-span is long.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[brief description of the drawings]
Fig. 1 is a kind of structural representation of the utility model.
In figure: 1 comprehensive wastewater pond, 2 one-level settling tanks, 3 second-level settling ponds, 4 biochemical reaction tanks, 5 second ponds, 6 sludge thickeners, 7 pressure filter.
[embodiment]
Consult Fig. 1, the utility model comprises comprehensive wastewater pond 1, one-level settling tank 2, second-level settling pond 3, biochemical reaction tank 4, second pond 5, sludge thickener 6 and pressure filter 7, described comprehensive wastewater pond 1, one-level settling tank 2, second-level settling pond 3, biochemical reaction tank 4 is connected from front to back successively with second pond 5, the sludge outlet of described one-level settling tank 2 connects sludge thickener 6, the outlet of described sludge thickener 6 connects pressure filter 7, the sludge outlet of described second pond 5 connects biochemical reaction tank 4, the sludge outlet of described biochemical reaction tank 4 connects sludge thickener 6, described pressure filter 7 adopts Car formula automatic pressure filter, described sludge thickener 6 adopts vertical-flow concentration basin.
The utility model working process: a kind of defatting-bonderizing Sewage treatment systems of the utility model in the course of the work, collect first and regulate in comprehensive useless pond 1 after fine fack is removed large suspended substance by factory effluent, the middle waste water regulating is forced into one-level settling tank 2 through lift pump and arrives second-level settling pond 3, pass through chemicals treatment, remove the most of phosphorus in waste water, degrading organic pollutant, second-level settling pond 3 water outlets enter biochemical reaction tank 4 and remove the organism in waste water, carry out denitrification, carry out the removal of COD and nitrated, outputted aerobic water adds a small amount of flocculation agent to remove remaining suspended substance after second pond 5 mud-water separation, reach the emission standard of demand, in second pond 5, remain aerobic sludge and be back to biochemical reaction tank 4, excess sludge in biochemistry pool enters in sludge thickener 6 concentrated.Mud in sludge thickener 6, after concentrated, adopts chamber-type press filter 7 to dewater, and mud cake outward transport landfill is disposed.The utility model, reaches effluent standard by discharge after defatting-bonderizing sewage disposal.Also there is convenient operation and management simultaneously, stable performance, reliable, the advantage that the life-span is long.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
