Abstract

This utility model relates to a kind of flower bed diafiltration clean device purified for roof rain water, and it is arranged on external wall side, oozes pipe including downpipe, flower bed pond and draining;Described downpipe is vertically arranged on external wall, and its bottom is positioned at above flower bed pond;Cobble or slag layer, fine sand layer, coarse sands layer, Artificial Soil or back fill course it is equipped with the most successively in described flower bed pond;Described draining is oozed pipe and is embedded in advance in cobble or slag layer, and extends outside flower bed pond;Plant on described Artificial Soil or back fill course and be implanted with plant.This utility model is at flower bed pond layer overlay Artificial Soil or back fill course, then at soil top planting plants, bottom arranges draining and oozes pipe, after Roof Runoff rainwater is by plant, edaphic absorption and filtering, Runoff is obviously improved, and the especially SS content in rainwater can significantly reduce, so can save the pre-control measure of early-stage rainwater, both beautified environment, and purified again rainwater, and rainwater resource is made full use of.

Description

A kind of flower bed diafiltration clean device purified for roof rain water
Technical field
This utility model relates to a kind of rainwater purification apparatus, is specifically related to a kind of flower bed diafiltration purified for roof rain water Purifier, belongs to water resource recycling device technical field.
Background technology
At present, country advocates sponge urban construction energetically, advances region entirety to administer, the rainwater pollution degree that roofing is collected Gently, can directly recycle, alleviate the load of urban flood control and drainage and processing system, promote urban ecological system function and subtract The generation of few Urban Flood Waterlogging.The most external pollution cutting device having some sizings, domestic actually used case is less.
Therefore, for solving above-mentioned technical problem, the flower bed purified for roof rain water of a kind of innovation of necessary offer Diafiltration clean device, to overcome described defect of the prior art.
Utility model content
For solving the problems referred to above, the purpose of this utility model is to provide one both to beautify environment, has purified again rainwater, And the flower bed diafiltration clean device purified for roof rain water that rainwater resource made full use of.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of flower bed purified for roof rain water Diafiltration clean device, it is arranged on external wall side, oozes pipe including downpipe, flower bed pond and draining;Wherein, described overboard Pipe is vertically arranged on external wall, and its bottom is positioned at above flower bed pond;Ovum it is equipped with the most successively in described flower bed pond Stone or slag layer, fine sand layer, coarse sands layer, Artificial Soil or back fill course;Described draining is oozed pipe and is embedded in advance in cobble or slag layer, and Extend outside flower bed pond;Plant on described Artificial Soil or back fill course and be implanted with plant.
The flower bed diafiltration clean device purified for roof rain water of the present utility model is further arranged to: described downpipe Being provided with and cut dirty filter screen, the aperture of this filter screen is 2mm to 10mm.
The flower bed diafiltration clean device purified for roof rain water of the present utility model is also configured to: described flower bed pond and building Build and between exterior wall, be filled with water tight packing.
Compared with prior art, this utility model has the advantages that of the present utility model clean for roof rain water The flower bed diafiltration clean device changed is at flower bed pond layer overlay Artificial Soil or back fill course, then at soil top planting plants, Bottom arranges draining and oozes pipe, and after Roof Runoff rainwater is by plant, edaphic absorption and filtering, Runoff is obviously improved, The especially SS content in rainwater can significantly reduce, and so can save the pre-control measure of early-stage rainwater, both beautify environment, Purify again rainwater, and rainwater resource has been made full use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of the flower bed diafiltration clean device purified for roof rain water of the present utility model.
Detailed description of the invention
Referring to shown in Figure of description 1, this utility model is a kind of flower bed diafiltration clean purified for roof rain water Device, it is arranged on external wall 10 side, downpipe 1, flower bed pond 2 and draining oozes several parts such as pipe 3 and form.
Wherein, described downpipe 1 is used for collecting rainwater, and it is vertically arranged on external wall 10, and its bottom is positioned at flower bed Above pond 2.Described downpipe 1 is provided with and cuts dirty filter screen 4, and the aperture of this filter screen 4 is 2mm to 10mm, can intercept leaves, birds droppings etc. Big pollutant, it makes of wire netting or plastic wire, can suitably reduce rainwater and impact flower bed soil.
It is filled with water tight packing 7, it is to avoid rainwater penetrates into external wall 10 between described flower bed pond 2 and external wall 10.Should Cobble or slag layer 21, fine sand layer 22, coarse sands layer 23, Artificial Soil or back fill course it is equipped with the most successively in flower bed pond 2 24.In in water, the suspended material such as granule, jelly is retained in fine sand layer 22, coarse sands layer 23, Artificial Soil or back fill course 24, water warp Cross cobble or slag layer 21 is flowed out by bottom.Plant on described Artificial Soil or back fill course 24 and be implanted with plant 5.
Described draining is oozed pipe 3 and is embedded in advance in cobble or slag layer 21, and extends outside flower bed pond 2, and it is by cobble or slag Water in layer 21 is discharged.
Can be organic to antibacterial, virus, macromole close to 100% by the clearance of float in the rainwater in flower bed pond 2 The impurity such as thing, colloid, ferrum have removal effect significantly;The rate of filtration is fast, generally 30-45m/h;Retaining power is big, generally 5-15kg/m;Comprehensive cost performance is high, in the case of same treatment amount, identical water index, only increases associated materials loading and combines Conjunction expense about 50%, sewage disposal index improves a grade.After filtering blowdown, effluent quality can reach: CODcr≤30mg/ L;SS≤5mg/L, be suitable for road water spill, Afforestation Landscape water body moisturizing etc..
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, all in this wound Any modification, equivalent substitution and improvement etc. done within the spirit made and principle, should be included in this creation protection domain it In.
