2) water inlet is assigned in ecological barrel by water distributor 3 and water distributor aperture 11 equably, under the acting in conjunction of inlet pipe 4, aeration tube 5 and aeration tube aperture 12, aeration is carried out in water inlet, dissolved oxygen content is controlled at 2-4mg/L, further removes solvability five-day BOD (BOD by the oxygenolysis of microorganism ₅).

3) fluidised form of sewage in ecological barrel is flow lifting type, upflow velocity is controlled at 5.0-5.5m/h, water is from bottom to top through aeration zone (clean-up stage supporting layer 8 is to the part between aeration tube 5), further enter clean-up stage (clean-up stage supporting layer 8 is to the part between overflow groove 9) after oxygenolysis, reduce by coarse sands layer 14 and fine sand layer 15 and water suspension, after enter turfy soil layer 16, this layer planted the denitrogenations such as Chinese celery, Scirpus tabernaemontani, fishscale bamboo, Canna generalis Bailey, dephosphorization ability by force and the ornamental plant of well developed root system, to reduce the indexs such as water outlet nitrogen, phosphorus.

4) filtration of process clean-up stage, water outlet enters overflow groove 9 and effluxes by rising pipe 6, water meter is used for recording the reuse water water yield, the ecological barrel effluent quality can satisfy " urban sewage reutilization water for scenic environment use " water quality standard, and namely the concentration of five-day BOD, suspended substance, total phosphorus (in P), total nitrogen and ammonia nitrogen (in N) is controlled at respectively in 10mg/L, 20mg/L, 1.0mg/L, 15mg/L and 5.0mg/L.

5) tapered bucket 10 is as the silt particle bucket, is used for collecting the suspended substance and the silt particle that are filtered out by ecological barrel clean-up stage coarse sands layer 14 and fine sand layer 15, gets rid of suspended substance and silt particles by shore pipe 7.

6) ventpipe 18 and ventpipe aperture 19 are used for increasing the gas permeability of soil and clean-up stage current percent of pass.

The above is only preferred embodiments of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
