Utility model content
In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a kind of catch-basin biology mistakes Filter system is a kind of technique system for being filtered degradation to rain water pollutant based on the eco-filtration technology based on filtrate System, the system be based on filtrate, using " bottom in and top out " formula filtering technique remove rainwater in pollutant, complete to pollution level compared with Removal is filtered in the retention of the pollutant through washing away carrying in big initial rainwater and Storm Sewer Network.
The utility model design thus uses following scheme:
A kind of catch-basin biological filter system including catch-basin, is laid in the catch-basin along the cross section of catch-basin Biofiltration disk, one side of the biofiltration disk are the intake tunnel of only upper and lower opening, the intake tunnel and the rainwater borehole wall The water inlet pipe connection of upper connection;The middle part of the biofiltration disk is double-layer structure, and lower floor is biological filtering module, and upper strata is filter Aquaporin;The top of the biofiltration module is connected with drainage channel, and the lower section of biofiltration module is connected with catch-basin, institute It states in catch-basin and is equipped with grid in the lower section of biofiltration module;The another side of the biofiltration disk is exhalant canal, described Drainage channel is connected with exhalant canal, and the exhalant canal is connected with the outlet pipe connected on the rainwater borehole wall;The biofiltration Module, drainage channel and exhalant canal are enclosed construction in addition to the connectivity part.
Further, the biofiltration module includes several net cages and the filtrate being built in net cage, the filtrate Surface is attached with microorganism;The top and bottom of the net cage are permeable, and the peripheric surface of net cage is watertight housing.
Further, the filtrate is plastics or gravel.
Further, the grid is in bell shape, is connected below the top of grid and biofiltration module.
Further, the center of the biofiltration disk is equipped with the soil pick-up channel through biofiltration disk and grid.
The beneficial effects of the utility model are:
The utility model increases biofiltration dish structure in catch-basin, and the disk of biofiltration disk is separated into both sides Intake tunnel, exhalant canal, middle part are that biological filtering module and drainage channel, grid are located at the lower section of biofiltration module, are used In the larger floating material for screening out rainwater carrying in pipeline;The filter type of biofiltration module be " bottom in and top out " formula, for into One step filters the retention of rain water pollutant, and the microorganism by being attached to filter material surface carries out biodegradation, and drainage leads to Road is located above filtering module, for collecting the rainwater after modular filtration, and discharges catch-basin through outlet pipeline.
The utility model removes rain based on the eco-filtration technology based on filtrate using " bottom in and top out " formula filtering technique Pollutant in water completes the retention of the pollutant through washing away carrying in the initial rainwater larger to pollution level and Storm Sewer Network Filtering removal is urban rainwater collection and the disruptive technology of processing.
Description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, wherein:
Fig. 1 is the structure diagram of the utility model;
Fig. 2 is the structure diagram of biofiltration module;
Wherein:1- water inlet pipes;2- outlet pipes;3- grids;4- intake tunnels;5- exhalant canals;6- biofiltration modules; 61- filtrates;62- net cages;7- drainage channels;8- catch-basins;9- soil pick-up channels.
Specific embodiment
With reference to a kind of catch-basin biological filter system shown in FIG. 1, including catch-basin 8, along catch-basin in the catch-basin 8 8 cross section is laid with biofiltration disk.
The center of the biofiltration disk is soil pick-up channel 9, is four segments around central compartment.The segment on the left side The intake tunnel 4 of only upper and lower opening is formed, the intake tunnel 4 is connected with the water inlet pipe 1 connected on 8 wall of catch-basin(This implementation Intake tunnel 4 in example is right against the lower section of 1 nozzle of water inlet pipe, can also directly connect water inlet pipe 1 with intake tunnel 4.).
Two segments at the middle part of the biofiltration disk are double-layer structure, and lower floor is biological filtering module 6, and upper strata is Filter water channel 7;The top of the biofiltration module 6 is connected with filter water channel 7, lower section and the catch-basin 8 of biofiltration module 6 Connection, the catch-basin 8 is interior to be equipped with grid 3 in the lower section of biofiltration module 6;The grid 3 be in bell shape, for screen out into The larger floating material that rainwater carries in water pipe 1, the top of grid 3 connect with the lower section of biofiltration module 6, avoid untreated rain Water directly surmounts grid 3 and enters biofiltration module 6.
With reference to shown in Fig. 2, the biofiltration module 6 includes several net cages 62 and the filtrate being built in net cage 62 61, the filtrate 61 is plastics or gravel, and 61 surface of filtrate is attached with microorganism;The top and bottom of the net cage 62 are permeable, net cage 62 peripheric surface is watertight housing.
The segment on the right of the biofiltration disk forms exhalant canal 5, and the filter water channel 7 connects with exhalant canal 5 Logical, the exhalant canal 5 is connected with the outlet pipe 2 connected on 8 wall of catch-basin;Above-mentioned biofiltration module 6, filter water channel 7 with And water outlet logical 2 is enclosed construction in addition to the connectivity part, the whole filter type using " bottom in and top out ".
Soil pick-up channel 9 runs through biofiltration disk and grid 3, for the drift for intercepting 6 lower section of biofiltration module through grid 3 Discharge is sucked out in float.
The operation principle of the utility model is as follows:
Initial rainwater is by urban road surfaces after rain perforaled strainer imports Storm Sewer Network, and at 8 position of catch-basin, rainwater leads to It crosses water inlet pipe 1 to be flowed into catch-basin 8, the upper opening through intake tunnel 4 enters the lower section of catch-basin 8 first, with rainwater Continuous entrance, the water surface in catch-basin 8 is gradually increasing, and larger floating material is filtered through grid 3 and retained in rainwater, after enter Biofiltration module 6, flow from bottom to top, under the filtrate 61 and its microbial action in being built in net cage 62, in rainwater Pollutant is further filtered, and removal of degrading, and the rainwater after filtering enters filter water channel 7 from biological 6 top of filtering module, Outlet pipe 2 is entered by exhalant canal 5 afterwards, so as to discharge catch-basin 8.
After rainfall, then can be removed the well lid of catch-basin 8, and using suction-type sewer scavenger by soil pick-up channel 9 by biofiltration Discharge is sucked out in the floating material that 6 lower section of module is intercepted through grid 3.
The preferable specific embodiment of the above, only the utility model, but scope of protection of the utility model is not limited to In this, in the technical scope that any one skilled in the art discloses in the utility model, the change that can readily occur in Change or replace, should be covered within the scope of the utility model.Therefore scope of protection of the utility model is with claim Subject to the protection domain of book.
