[0002] In the field of deodorization, the solution at the bottom of the biofilter tank is usually discharged directly when it falls to the bottom after spraying once, which wastes water resources, and some cultured biological strains will be discharged along with the solution, affecting the cultivation of biological strains, thereby affecting the odor treatment effect. Most of the bottom solutions are discharged by gravity. If the distance is far or there is a height difference, there will not be enough power to discharge to the designated location. If it is to be discharged to a designated location with a height difference, an additional water pump is required, which wastes resources and increases costs. When multiple sets of biofilters are used for deodorization at the same time, each set will be equipped with a corresponding number of circulating water tanks and circulating pipelines according to process requirements, which also increases costs invisibly.

[0003] Therefore, a sequencing batch humidification internal circulation biological deodorization system is needed to achieve the deodorization effect while saving energy and cost; through the internal circulation system, the biological bacteria carried away by the spray water can be circulated into the filler, which is conducive to the cultivation of biological bacteria and improves the treatment effect.

[0007] The biological filter tanks are provided with two left and right ones, and the structures are mutually symmetrical. The two biological filter tanks share a humidification system and a circulating water tank. The biological filter tanks have an air outlet on the top and an air inlet on the side.

[0008] A humidification system is arranged above the inside of the two biofilter tanks and between the tanks, a spray pipeline is installed above the inside of the biofilter tank, a nozzle is arranged on the spray pipeline, and the middle end of the two groups of spray pipelines is connected to the discharge pipe through an electric four-way valve;

[0009] The humidification system and the circulating water tank are connected through a pipeline. Filter plates are installed on both sides of the circulating water tank. A water supply pipe is arranged on the circulating water tank. An electric valve 2 is installed on the pipeline of the water supply pipe.

[0010] Furthermore, the biofilters are composed of horizontal box structures connected in parallel.

[0011] Furthermore, the electric four-way valve is connected to the discharge pipe upward, and the electric four-way valve is connected to the circulating water tank downward.

[0012] Furthermore, two parallel branches are arranged on the connecting pipeline between the electric four-way valve and the circulating water tank, and both branches are equipped with a circulating pump, a check valve, a flexible joint and a manual valve.

[0013] Furthermore, the circulating water tank is connected to the bottom of the biofilter tank via a pipeline, and an electric valve is installed on the pipeline.
