A uniform water distribution port is arranged on the water distribution pipe.

The above-mentioned adsorptive fillers are mostly zeolite, ceramsite activated carbon, gravel, etc., and the filling thickness is 30-100cm.

The first-stage cylindrical casing and the third-stage cylindrical casing are uniformly arranged with holes near the bottom, and are wrapped with a filter mesh.

The cylindrical shells are all made of glass fiber reinforced plastics.

The sewage in the multi-stage ecological filter adopts the principle of U-shaped pipes and flows in a V-shape to increase the contact area and improve the treatment effect.

The utility model has the advantages of:

The device has the advantages of simple and compact structure, stable performance, no need for power, low energy consumption, easy installation and disassembly, short construction period, low cost, good treatment effect, etc., which can promote the control of domestic sewage. Utilization, effectively saving water resources, especially suitable for decentralized domestic sewage treatment.

detailed description

A multi-stage integrated domestic sewage treatment device includes a static anaerobic box 1 and a multi-stage ecological filter 2. The static anaerobic box 1 includes a water inlet pipe 3, a mud discharge pipe 8, an elastic three-dimensional packing 4, and a water outlet pipe 12. The multi-stage ecological filter 2 includes plants 5, water distribution pipes 6, absorbent fillers 9, drain pipes 11, overflow ports 7, first-stage cylindrical shells 13, second-stage cylindrical shells 14, and third-stage cylindrical shells 15 and the fourth-stage cylindrical shell 16.

The bottom side of the anaerobic box is connected to the water inlet pipe 3, and the lower end is connected to the mud discharge pipe 8. The upper end of the anaerobic box 6 is provided with a water outlet pipe 12, and the water outlet pipe 12 is connected to the water distribution pipe 6. The elastic three-dimensional packing 4 is uniformly distributed in the anaerobic box 1 .

The multi-stage ecological filter 2 is provided with a four-stage filter system sequentially from the inside to the outside. Adsorptive fillers 9 with different particle sizes from large to small are respectively placed, and water-resistant plants 5 are planted on the surface. The bottom of the first and third shells is provided with a uniform drainage hole 10, the top of the second shell is provided with an overflow port 7, and the fourth shell is connected to the drain pipe 11 near the top, and the water entering the ecological filter uses a U-shaped pipe The principle is to make the water flow in a V shape, increase the hydraulic retention time and contact area, and enhance the removal effect.

The casing of the anaerobic chamber 1 is respectively provided with a mud discharge pipe 8 and a water inlet pipe 3, and the water distribution pipe 6 connected to the outlet pipe 12 is provided with a uniform water distribution port. Adsorptive fillers 9 are gravel, ceramsite, zeolite and activated carbon, etc., which can be adjusted according to actual conditions, and the filling thickness is 30-100cm. The first and third stage shells are evenly arranged with drainage holes 10, and are wrapped with filter screens. The multi-level integrated domestic sewage treatment device is made of glass fiber reinforced plastic.

The multi-stage integrated domestic sewage treatment device has compact structure and stable performance, and can be widely used in domestic sewage treatment. During work, the sewage enters the anaerobic chamber 1 from the water inlet pipe 3, undergoes microbial degradation through the elastic three-dimensional packing 4, and stands still. The microorganisms attached to the elastic three-dimensional packing 4 will flocculate, flocculate, Interception, adsorption, and decomposition are carried out for microbial degradation, and the remaining sludge is discharged through the sludge discharge port 8, thereby completing the preliminary treatment of domestic sewage.

The domestic sewage that has completed the preliminary treatment enters the multi-stage ecological filter 2 through the outlet pipe 12 through the water distribution pipe 6, and is treated by the physical and chemical effects of the water-resistant plants 5 and the adsorbent filler 9, and is passed through the V-shaped flow between different treatment stages. Enhance the contact area and promote the occurrence of adsorption and degradation reactions. Through the adsorption of the first-stage plants 5 and the adsorptive filler 9, the water enters the second-stage osmotic system through the bottom drainage hole 10, and the water flows through the adsorbent filler, and is discharged to the third-stage filter system through the upper overflow port 7. Repeat the process of the first level to reach the fourth level, after being processed by the fourth level system, it is discharged from the drain pipe 11 at the top of the system, and the discharge reaches the standard. The multi-level integrated domestic sewage treatment device has the characteristics of easy installation and disassembly, short construction period, low cost and good treatment effect, so that domestic sewage can be used rationally and water pollution can be effectively controlled.
