Specific implementation mode
The specific embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
In the utility model description, it is to be understood that the indicating positions such as term "upper", "lower" or position relationship are bases
Position relationship described in attached drawing is merely for convenience of description the utility model or simplifies description, rather than instruction must have
Specific orientation.Fig. 1 to Fig. 3 illustrates a kind of shallow-layer filter, including spherical cylinder shell 1, the spherical shape cylinder shell 1 it is upper
End be equipped with inlet 3, sewage draining exit 2 and upper hole 5, lower end be equipped with liquid outlet 10 and lower opening 11, middle part be equipped with mesoporous 8, upper hole 5, under
Hole 11, mesoporous 8 are the manholes for sealing waterproof, can be used to observation, maintenance and inspection and manual cleaning etc.；The spherical shape cylinder shell 1
The interior water distributor 1. 4 for being equipped with connection inlet 3,1. 4 lower sections are equipped with the first filter layer 6 to water distributor, and first filter layer 6 is hole
Gap filter layer, the concave-convex filter layer that specially several square pyramids join together, square frustum is interior to be equipped with filter hole 62, institute
It is aperture 61 that state filter hole 62, which be water inlet end, and water outlet is the filter hole 62 of macropore, can be specifically round table-like filter hole 62,
Or square pyramid bench-type；The lower section of first filtering layer 6 is equipped with the second filter layer 7, and second filter layer 7 is equipped with catchmenting
Device 1. 14 quartz sand filtration layer, quartz sand be diameter be 0.5-1.2mm particulate quartz sand, the water collector 1. 14 connection cloth
