A composite ecological filter tank with bidirectional and alternate water distribution

By using a composite ecological filter design with bidirectional alternating water distribution, solid-liquid separation and purification are achieved through components such as mesh cylinders, filter plates, and impellers. This solves the clogging problem caused by solid particles in sewage, ensuring the efficiency of sewage treatment and the stable operation of the ecological filter.

AI Technical Summary

Technical Problem

When treating wastewater, existing composite ecological filters are prone to clogging and damaging plant roots due to solid particles in the wastewater, thus affecting the filtration effect.

Method used

The composite ecological filter design adopts a two-way alternating water distribution system, including a separation tank, a clear water tank, a collection tank, and a composite tank. Solid-liquid separation and purification are achieved through components such as mesh cylinders, filter plates, pendulums, and impellers. Combined with aeration and phosphorus removal, the wastewater treatment effect is ensured.

Benefits of technology

It effectively avoids clogging, ensures the efficiency and effectiveness of sewage treatment, ensures uniform nutrient absorption by plants, and maintains the stable operation of the ecological filter.

Abstract

The application discloses a bidirectional alternating water distribution composite ecological filter tank, which comprises a separation tank, a clean water tank and a sewage treatment mechanism, the sewage treatment mechanism comprises a plurality of water collecting tanks and composite tanks which are alternately arranged between the separation tank and the clean water tank, the separation tank is used for solid-liquid separation of sewage, and the composite tank is used for purification treatment of the sewage; a mesh cylinder and a filter plate are arranged in the separation tank, the separation tank filters sewage through the mesh cylinder and the filter plate, a guide plate and a discharge plate are fixedly connected to the top end and one side of the mesh cylinder in the separation tank, the side close to the mesh cylinder of the guide plate and the discharge plate is tangent to the mesh cylinder, a plurality of pendulums are arranged below the filter plate in the separation tank, and the pendulums are used for knocking the filter plate. The plurality of water collecting tanks and the composite tanks are alternately arranged between the separation tank and the clean water tank, the separation tank can be used for solid-liquid separation of sewage, and solid particles and sundries in the sewage can not affect the effect and efficiency of subsequent sewage treatment.
