Description
Technical field
The utility model belongs to the sewage treatment equipment field, particularly relates to a kind of high concentration suspended matter wastewater filtering device of difficult precipitation difficult for biological degradation.
Background technology
China is the country of a serious water shortage.Although China's freshwater resources total amount is abundant, water resource is one of the poorest country in the whole world per capita.The expert estimates that the peak of Chinese lack of water will appear at the year two thousand thirty, enters the ranks of definite moderate lack of water country of related organization of the United Nations.Simultaneously, China's water pollution is serious, water effectively utilize degree lower.Municipal sewage and treatment rate of industrial effluents and degree of treatment are low at present, and the increase of quantity of wastewater effluent has caused that water body environment worsens and quite general body eutrophication phenomenon; In order to control pollution, effectively utilize precious water resource, the advanced treating of water and sewage reaches utilizes work very urgent again.
Processing for high suspended matter waste water mainly is divided into physico-chemical process and biochemical process two big classes usually.Biochemical process requires than higher waste water quality, the length consuming time of degrading, and a lot of discharged waste water is normally seasonal, often changes, and does not often reach the expection treatment effect because measure lags behind.Filtration is mainly used in the solid suspension of removing in the water, and in water technology, thereby filtration is to make water obtain the technical process of clarification with the impurity in the particulate filter layer trap water with hole.Existing sewage filter device complex structure, power consumption is high, is difficult for implementing, not easy-maintaining.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of circular terrace-type sedimentation and filtration sewage-treatment plant, utilizes gravity principle, realizes sedimentation and filtration integrated multistage sewage disposal, to solve energy consumption height in the prior art, complicated operation, the problem of inconvenient maintenance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of circular terrace-type sedimentation and filtration sewage-treatment plant is provided, include the mouth of a river, the bottom is del central circular sedimentation basin, the first micro-filtration cloth filter plate, the second micro-filtration cloth filter plate, the 3rd micro-filtration cloth filter plate, first decanting zone, second decanting zone, discharge outlet, mud mouth, described sedimentation basin, first decanting zone, second decanting zone is positioned on the concentric circles, sedimentation basin is higher than first decanting zone, second decanting zone, first decanting zone is higher than second decanting zone, the three is stairstepping and distributes, the described first micro-filtration cloth filter plate, the second micro-filtration cloth filter plate, the 3rd micro-filtration cloth filter plate is respectively along sedimentation basin, first decanting zone, the second decanting zone edge placement.
The described first micro-filtration cloth filter plate, the second micro-filtration cloth filter plate, the 3rd micro-filtration cloth filter plate are two-layer filter-plate structures, and filtration flux is 70L/m
2H, 30-40 μ m is selected in the flight micro-filtration cloth aperture of close sedimentation basin, and outermost layer micro-filtration cloth aperture is 2-20 μ m, between the first micro-filtration cloth filter plate and the second micro-filtration cloth filter plate, distance equates between the second micro-filtration cloth filter plate and the 3rd micro-filtration cloth filter plate.
The height of described sedimentation basin, first decanting zone, second decanting zone is from inside to outside than classifying 1: 1: 1 as.
Described first decanting zone, second decanting zone are circular.
Beneficial effect
The utility model has utilized the water body deadweight to be motive force, can save power source, cost is low, convenient operating maintenance, energy savings, cleaning is inverted inside and outside filter of the present utility model can be realized simultaneously, function can be recovered automatically when occurring stopping up, the only thick 2-3mm of filter cloth, and easy cleaning is clean, washing length is short, and effect is obvious.
The suspension separating effect is remarkable, effectively removes the particle that particle diameter is 0.1-10 μ m, and effluent quality is good, and solid suspension (SS) clearance is 100%, and the COD clearance can reach 10%-30%.Filter and sedimentation basin are built jointly, and floor space reduces greatly.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The utility model provides a kind of circular terrace-type sedimentation and filtration sewage-treatment plant, and this method is: referring to Fig. 1 and Fig. 2, it is by sedimentation basin 2; The first micro-filtration cloth filter plate 3, the second micro-filtration cloth filter plate 5, the 3rd micro-filtration cloth filter plate 7; Compositions such as first settling zone 4, second settling zone 6, sedimentation basin 2 is positioned at the highest center of water level, and the 3rd micro-filtration cloth filter plate and second decanting zone are set afterwards step by step, makes the concentration of suspension in the sewage be lower than 1mg/L; When stopping up appearred in micro-filtration cloth filter plate, the interior outside was inverted micro-filtration cloth filter plate is carried out backwash, and its filtering function is recovered.There is mud discharging mouth 9 the sedimentation basin bottom.
Its technical process is: as shown in Figure 1, waste water is from sewage inlet 1 CD pond 2, carrying out the I level through the first micro-filtration cloth filter plate 3 then filters, under the gravity effect, arrive first decanting zone 4 sedimentation once more through the water after the filtration of I level, water outlet after the secondary precipitation is carried out the II level through the second micro-filtration cloth filter plate 5 and is filtered, arrive second decanting zone 6 through the water after the filtration of II level and continue sedimentations, the water outlet after three sedimentations is carried out the filtration of III level through the 3rd micro-filtration cloth filter plate 7 after delivery port 8 outflows are used.Start standby micro-filtration cloth filter plate during backwash, can accomplish backwash after the outside is inverted in the micro-filtration cloth filter plate after the obstruction, the micro-filtration cloth filter plate after the backwash can be reused.
