Abstract
The utility model discloses an advanced sewage treatment system based on a deep micro-flocculation filtering technology. The system comprises a second sedimentation tank and is characterized in that the secondary sedimentation tank is connected with an efficient mixer through a pipeline; the efficient mixer is connected with a deep filter chamber through a pipeline; the deep filter chamber is connected with an ultraviolet disinfection tank through a pipeline; and a drainage hole is arranged at the output end of the ultraviolet disinfection tank, or the output end of the ultraviolet disinfection tank is connected with a reused water pipe. The direct micro-flocculation filtering technology omits the sedimentation process, completes the coagulation and filter processes synchronously in the filter chamber and is a novel contact flocculation filtering technology. Compared with the prior art, the flocculation tank and the sedimentation tank are reduced by the micro-flocculation filtering to save the disposable investment; and the removal rate is high, the outlet water quality is good, and the drug dosage is lower than that of the prior art.
Description
Technical field
The present invention relates to the advanced treatment of wastewater system, more particularly, relate to the improvement that treating pond etc. in the system is provided with link.
Background technology
According to the domestic Sewage Plant practical operating experiences of having built, secondary treatment yielding water can be stablized and reaches one-level B standard, stablize the one-level A standard that reaches, and must carry out three grades of advanced treatment.The major objective of advanced treatment is to remove SS, thereby further reduces the COD in the water outlet
Cr, BOD
5And TP, guarantee that stable water outlet is up to standard.
The treatment process of sewage work's advanced treatment prior art is: second pond water outlet → flocculation → precipitation → filtration → uv sterilisation pond → water outlet.The technical process of flocculation Depth Filtration is: second pond water outlet → Hi-mixer → Depth Filtration → uv sterilisation pond → water outlet.Problem is, because precipitation process need be set, has increased the investment of system, and the processing efficiency, the dosage that have reduced sewage simultaneously are also bigger.
Summary of the invention
The present invention handles the low-cloudy water matter of the second pond water outlet of sewage work, design is suitable for adopting little flocculation Depth Filtration technology of polymeric aluminum flocculating agent, advanced treatment is carried out in sewage work's second pond water outlet reach national sewage disposal one-level A standard, be and the Technology of practical.
In order to achieve the above object, the invention provides a kind of advanced treatment of wastewater system, comprise secondary sedimentation basins based on little flocculation Depth Filtration technology.Described secondary sedimentation basins is connected to Hi-mixer by pipeline, and described Hi-mixer is connected to the deep layer filter tank by pipeline, and described deep layer filter tank is connected to the uv sterilisation pond by pipeline, and the output terminal in described uv sterilisation pond is provided with discharge outlet or connects the reuse water pipe.
The little flocculation deep layer of the present invention direct filtration technology technology, actual is on the basis to coagulation, filteration mechanism and technological process further investigation thereof, is one with coagulation and filtration procedure organic integration, forms the new and high technology of current water treatment.Can be widely used in the upgrading and advanced treatment process process of urban wastewater treatment firm.The little flocculation direct filtration of the present invention technology is to save precipitation process and a kind of novel contact flocculation filtration process technology that coagulation and filtration procedure are finished in the filter tank inter-sync.Compare with the flocculation-precipitation-filter depth treatment process of prior art, micro flocculating filter has reduced flocculation basin and settling tank, has saved one-time investment; The micro flocculating filter advantage is that clearance height, effluent quality are good, dosage is lower than flocculation-precipitation-filtration process.
Under the optimal way, the optimum chemical of little flocculation direct filtration technology and hydraulic parameter are selected the filtrate of particle diameter 2～4mm for use; Filtering velocity can be brought up to 30m/h, and can reach 24h filtration cycle.The advanced performance of its technology is as follows:
1, flow process aspect, this technology has been saved flocculation tank and inclined-plate clarifying basin, has shortened technical process, can reduce investment outlay nearly 1/2;
2, yield aspects also improves 1～2 times filtration cycle, and producing water ratio improves 2～4 times at least;
3, medicament aspect, medication economizes.
4, effluent quality aspect, effluent quality is good, and effluent quality can be stablized the one-level A standard that reaches.
Description of drawings
Fig. 1 is the theory structure synoptic diagram that the present invention is based on the advanced treatment of wastewater system improvement section of little flocculation Depth Filtration technology.
Embodiment
Based on the advanced treatment of wastewater system of little flocculation Depth Filtration technology, comprise secondary sedimentation basins of the prior art as shown in Figure 1, and essential before this treating part.Improvement of the present invention is, described secondary sedimentation basins is connected to Hi-mixer by pipeline, described Hi-mixer is connected to the deep layer filter tank by pipeline, and described deep layer filter tank is connected to the uv sterilisation pond by pipeline, and the output terminal in described uv sterilisation pond is provided with discharge outlet or connects the reuse water pipe.
The present invention's Depth Filtration technology process flow process of flocculating is: second pond water outlet → Hi-mixer → Depth Filtration → uv sterilisation pond → water outlet.In the treating processes of Hi-mixer, add flocculation agent.
The little flocculation direct filtration of the present invention technology is to save precipitation process and a kind of novel contact flocculation filtration process technology that coagulation and filtration procedure are finished in the filter tank inter-sync.The second pond water outlet of municipal wastewater treatment plant through after the water pump lifting, with after flocculation agent mixes, enters the deep layer filter tank by Hi-mixer, from top to bottom by filtering layer, after the filter clear water from the outflow of bottom, filter tank, behind uv sterilisation, qualified discharge.
The above; only be the preferable embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
