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.
