NOVELTY - Constructing garden filter sewage processing device, is claimed, where the device comprises a pool body (1), a shallow water tank (2) and a deep water tank (3), the pool body is made of industrial composite material with underground concrete structure, half underground concrete structure or a hard water impermeable structure, the height of the pool body is 1.2-3 m, a breathing stake is formed with holes, and the pool body is set with 1-2.5 m of filling layer, 0.1-0.2 m of isolation layer (6), 0.1-0.3 m of pervious brick paving layer (7) and a wood layer.    USE - The garden filter sewage processing device is useful for dispersion standard treatment on domestic sewage from towns, housing estates, enterprises, public institutions and builds, and treating livestock and poultry farms wastewater.    ADVANTAGE - The method constructs the garden filter sewage processing device with good lasting effect. The device has less land consumption and less weather influence, does not produce secondary pollution, can be easily and economically maintained in a convenient manner, and reduces municipal sewage treatment pressure.    DETAILED DESCRIPTION - Constructing garden filter sewage processing device, is claimed, where the device comprises a pool body (1), a shallow water tank (2) and a deep water tank (3), the pool body is made of industrial composite material with underground concrete structure, half underground concrete structure or a hard water impermeable structure, the height of the pool body is 1.2-3 m, a breathing stake is formed with holes, the pool body is set with 1-2.5 m of filling layer, 0.1-0.2 m of isolation layer (6), 0.1-0.3 m of pervious brick paving layer (7) and a wood layer, two sides of the pool body is fixed with a sleeve pipe through a wall, a top part of the sleeve pipe is shorter than the filling layer and connected with a water outlet pipe, two processing devices and a water inlet pipe, and a garden filter preprocess the entering sewage to remove floating material and particulate matters.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a garden filter sewage processing device.    Pool body (1)    Shallow water tank (2)    Deep water tank (3)    Isolation layer (6)    Pervious brick paving layer.. (7)
