Abstract

The utility model provides a rainwater filtering system. The rainwater filtering system comprises a water-filtering blind drain (1) and a filter (2), wherein the water-filtering blind drain (1) is arranged below a vegetation shallow drain (3), an water outlet of the water-filtering blind drain (1) is communicated with a water inlet of the filter (2) through a drainage pipeline (4), and the upper portion of the filter (2) is provided with a water-overflow gap which is communicated with a water-overflow pipeline (5). Firstly, the vegetation shallow drain is used to carry out a first treatment on rainwater; and secondly, a filtering chamber is used to carry out a second treatment on the rainwater, therefore the rainwater filtering system is a combined method of a plant rainwater treatment way and a physics rainwater treatment way, and cost of rainwater treatment is reduced. Meanwhile, rainwater treatment effect is improved. The rainwater filtering system is an efficient landscape water body rainwater utilization system and has the advantages of being simple to operate and maintain and low in cost.

Description

The dmp filter system
Technical field
The utility model relates to water-treatment technology field, is specifically related to a kind of dmp filter system.
Background technology
In the prior art, the rainwater treatment process mainly comprises: the activated sludge process of second-stage treatment and the activated sludge process of tertiary treatment; Wherein, The activated sludge process of second-stage treatment becomes the main flow technology of municipal sewage treatment so that its technology is ripe, stable relatively, treatment effect is good; But the major defect that this kind treatment process exists is: initial cost is big, and working cost is high, and; It mainly can remove the carbon source pollutent, and almost can not remove nutritive substances such as nitrogen, phosphorus.Therefore, there is environmental problems such as " eutrophication " in the water after the processing.And for the activated sludge process of tertiary treatment, though can solve environmental problems such as " eutrophication ", still there are defectives such as cost height, working cost costliness in it, therefore, has limited the large-scale application of the activated sludge process of tertiary treatment.
The utility model content
To the defective that prior art exists, the utility model provides a kind of dmp filter system, can effectively carry out filtration treatment to rainwater, thus the water preferably of the water quality after obtaining handling; And, also have the low and low advantage of working cost of cost, especially suitable large-scale application.
The technical scheme that the utility model adopts is following:
The utility model provides a kind of dmp filter system, comprising: drainage french drain (1) and strainer (2); Said drainage french drain (1) is arranged on the below of vegetation shallow ridges (3); The water outlet of said drainage french drain (1) is communicated with the water-in of said strainer (2) through drainage pipeline (4); The top of said strainer (2) is provided with the spillway that is communicated with overflow pipe (5).
Preferably, in said strainer (2) is installed in also or in the darkroom.
Preferably, said strainer (2) comprising: filtration chamber (6) and reservoir chamber (7); Said filtration chamber (6) isolates through water tightness closure (8) with the lower space of said reservoir chamber (7); Said filtration chamber (6) isolates through vertical filter plate (9) with the upper space of said reservoir chamber (7); The water inlet of said filtration chamber (6) is communicated with the water-in of said strainer (2); Said spillway is installed in the top of said reservoir chamber (7).
Preferably, said vertical filter plate (9) is for being provided with the said vertical filter plate (9) of an above through hole.
Preferably, each said through hole evenly is provided with.
Preferably, the volume of said reservoir chamber (7) is 10L-300L.
Preferably, the volume of said reservoir chamber (7) is 100L.
The beneficial effect of the utility model is following:
The dmp filter system that the utility model provides at first carries out the first time through the vegetation shallow ridges to rainwater and handles, and through the filtration chamber rainwater is carried out the second time again then and handles; Be that a kind of plant treatment rainwater is handled the mode that rainwater combines with physical method; Promptly reduce the rainwater processing cost, simultaneously, improved the rainwater treatment effect again; Be a kind of high efficiency landscape water body rainwater utilization system, have running maintenance advantage simple and with low cost.
Description of drawings
The structural representation of the dmp filter system that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in Figure 1, the utility model embodiment provides a kind of dmp filter system, comprising: drainage french drain 1 and strainer 2; Drainage french drain 1 is arranged on the below of vegetation shallow ridges 3; The water outlet of drainage french drain 1 is communicated with the water-in of strainer 2 through drainage pipeline 4; The top of strainer 2 is provided with the spillway that is communicated with overflow pipe 5.Wherein, strainer 2 can be installed in the well or the darkroom in, strainer 2 comprises: filtration chamber 6 and reservoir chamber 7; Filtration chamber 6 isolates through water tightness closure 8 with the lower space of reservoir chamber 7; Filtration chamber 6 isolates through vertical filter plate 9 with the upper space of reservoir chamber 7; The water inlet of filtration chamber 6 is communicated with the water-in of strainer 2; Spillway is installed in the top of reservoir chamber 7.And vertical filter plate 9 can be for being provided with the vertical filter plate 9 of an above through hole, and through hole can evenly be provided with.The volume of reservoir chamber 7 is provided with according to actual needs, can be any volume between the 10L-300L, for example: 100L.
The working process of the dmp filter system that the utility model provides is:
When (1) untreated rainwater is flowed through the vegetation shallow ridges, the vegetation shallow ridges to rainwater at first precipitate, effect such as filtration, absorption and biological degradation, therefore, tentatively rainwater is handled, reached the purpose of pollutent in the first removal rainwater.
(2) rain penetration after the vegetation shallow ridges is handled is to the drainage french drain, again in drainage pipeline 4 inflow filters.
(3) flow into rainwater in the strainer, at first flow to filtration chamber 6, behind the 6 pairs of dmp filters in filtration chamber, enter into reservoir chamber 7, when reservoir chamber 7 median water level reach the height of spillway, discharge through spillway through vertical filter plate 9 with mobile mode upwards.
In sum; The dmp filter system that the utility model provides at first carries out the first time through the vegetation shallow ridges to rainwater and handles, and through the filtration chamber rainwater is carried out the second time again then and handles; Be that a kind of plant treatment rainwater is handled the mode that rainwater combines with physical method; Promptly reduce the rainwater processing cost, simultaneously, improved the rainwater treatment effect again; SS and organic pollutant in the rainwater can be reduced effectively, and part metals ion and oily substances such as Pb, Zn, Cu, Al can be effectively removed; And, can also remove part NH3-N and TP, SS also there is very high clearance.Again since in the urban runoff contamination indexs such as SS and COD, TP, TN have good dependency, when SS obtained higher clearance, other pollutents also can be removed accordingly.
Therefore, the dmp filter system that the utility model provides is an a kind of high efficiency landscape water body rainwater utilization system, has running maintenance advantage simple and with low cost.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be looked the protection domain of the utility model.
