As an improvement, the aperture sizes of the first filter screen, the second filter screen and the third filter screen are sequentially reduced, and impurities in the sewage are filtered in a layering mode.

As an improvement, the adsorption layer is filled with activated carbon, so that particle impurities still existing after passing through the filter tank and flowing along with water flow are effectively adsorbed.

As an improvement, the aeration disc is provided with uniformly distributed aeration micropores, on one hand, the aeration is uniform, so that oxygen is fully dissolved in water, and on the other hand, the aeration micropores have higher air pressure and can push water flow to promote water circulation.

As an improvement, an aeration valve is arranged on the aeration pipe close to an air compressor, and the supplied aeration quantity can be adjusted according to the requirement.

As the improvement, first basic unit be the soil horizon, the second basic unit mix the layer by what zeolite, soil and cinder mixture constitute, the third basic unit be the gravel layer, the gravel layer guarantees the stability of basic unit as the bottom, the layer of mixing by zeolite, soil and cinder mixture is favorable to getting rid of aquatic phosphorus element, guarantees to plant the aquatic plant normal growth on top soil horizon.

As an improvement, the aquatic plant is one or a mixture of more of reed, water onion, canna indica and wild rice stem, and the aquatic plants such as reed, water onion, canna indica and wild rice stem have developed root systems, dense stems and leaves, strong pollution resistance and cold resistance, and can beautify the environment and create economic benefits while purifying water quality.
