Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a biological filter absorption treatment device. Background Art

[0002] By filling filter media of a specific particle size in the biofilter, a thick biofilm can be formed on the surface of the filter media. Through the biofilm on the surface of the filter media, the pollutants in the sewage are degraded by microorganisms to achieve the purpose of improving the sewage treatment effect. The biofilter continues to operate, and the suspended solids and particulate matter purified increase, resulting in the continuous increase in the thickness of the biofilm, which hinders the pores between the filter media. At the same time, the filter media will become compacted due to the adhesion of surface dirt and particles. Backwash water treatment is used to directly impact the bottom layer of filter media from below to perform collision treatment on the filter media. The filter media filled in the biofilter is kept in the filter as a whole, and it is impossible to perform active collision and covering surface flushing treatment on the filter media in different areas and layers in the biofilter, so that the compaction of the filter media in the biofilter cannot be dealt with in a timely and effective manner. At the same time, the supporting material is stored in the interval space between the filter material and the aeration structure. The filter material close to the supporting material is easily mixed with the supporting material due to the impact, thereby destroying the stratification state and balance of the filter material layer in the biological filter, thereby affecting the biological filter's absorption and treatment effect on sewage and affecting the normal use of the biological filter. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a biological filter absorption and treatment equipment, which effectively separates and stores filter materials and covers different areas in the tank body by setting six filter material fixed-point modules. The filter material fixed-point modules become open to connect multiple filter material fixed-point modules and filter materials in each area, so that the filter materials can effectively absorb and treat sewage. The staggered hollow outer frame, the hollow inner frame and the positioning net disk can make the filter material fixed-point modules change from an open state to a closed state, so that the filter materials in the filter material fixed-point modules are placed in a separated independent closed space for backwash water treatment operations. The corresponding diversion release modules cooperate with a plurality of first expansion tubes and second expansion tubes that are parallel and staggered to effectively perform regional separation treatment of the filter materials and expand and loosen the filter materials from different areas of the corresponding space to treat the surface compaction of the filter materials, so as to solve the problems raised in the above-mentioned background technology.

The two ends of the second expansion tube extend into the corresponding through hole respectively, so that the second expansion tube can smoothly guide the flushing water to enter and release the flushing water outward.

[0010] Furthermore, since the diversion release module is positioned outside the filter material fixed-point module, the guide box is fixedly connected to the outer wall of the hollow outer frame, and the outer wall of the guide box is fixedly connected to the inner wall of the cell body, the diversion release module is stably connected between the corresponding filter material fixed-point module and the cell body.
