Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a mobile biological contact oxidation tank structure. Background Technology

[0002] Biological contact oxidation is a commonly used biological treatment process for wastewater. It utilizes biological packing materials and an aeration system to oxidize and decompose organic matter in wastewater into harmless substances. The biological packing material is a key component of this process, providing a good substrate for attachment and an ideal environment for the growth and reproduction of microorganisms. The aeration system is another important component of biological contact oxidation. It provides an ample oxygen supply by injecting oxygen into the wastewater, promoting the growth and metabolic activities of the microorganisms.

[0003] The prior art, CN112299662A, describes a micro-powered sewage treatment device. The prior art uses liquids of different heights in combination to achieve a flow effect. However, due to the obstruction of the packing material, the power of the underwater thruster in the prior art is often higher than that of the activated sludge method, resulting in increased power consumption. In addition, there is the possibility of the packing material getting entangled in the thruster, causing damage, and there is also the possibility of pipe blockage or uneven water output.

[0004] Therefore, it is necessary to design a mobile biological contact oxidation water tank structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mobile biological contact oxidation water tank structure to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A movable biological contact oxidation water tank structure includes a biological tank body, a packing support placed inside the biological tank body, and biological packing material uniformly filled on the packing support. An inlet pipe module is provided at the front end of the biological tank body. The structure is characterized by: several sets of positive and negative guide vanes that act as barriers are provided inside the biological tank body. The positive and negative guide vanes are alternately and uniformly distributed inside the biological tank body. A bottom flow channel is provided at the bottom of the positive guide vane, and a top flow channel is provided at the top of the negative guide vane. A sludge discharge pipe is provided at the bottom of the biological tank body and between the positive and negative guide vanes.

[0007] Preferably, guide vane lifting lugs are provided on both sides of the top of the positive guide vane and the negative guide vane.

[0008] Preferably, positive guide vanes are provided at both ends of the biochemical tank.

[0009] Preferably, the sludge discharge pipe is installed through the body of the biological treatment tank, and sludge discharge pipe connectors are installed at both ends of the sludge discharge pipe.

[0010] Preferably, the water inlet pipe module includes a water inlet interface located at the front end of the biochemical tank, a water inlet pipe connected to the water inlet interface, and a water distribution pipe located at the bottom of the biochemical tank and connected to the water inlet pipe.

[0011] Preferably, a biological treatment tank outlet weir is provided at the rear end of the biological treatment tank, and a biological treatment tank outlet is provided inside the biological treatment tank outlet weir.

[0012] The beneficial effects of this utility model are as follows: This technical solution sets up a guide plate with different water outlet channels and places the guide plate evenly in the biological treatment tank, dividing it into several groups of partitions to restrict the direction of water flow. Then, by setting up an inlet water distribution pipe, uniform water distribution is achieved, which serves as the driving force for water flow. Combined with the setting of the guide plate, the wastewater flows up and down in the biological treatment tank, allowing the packing material and wastewater in the anoxic tank to be fully mixed, reducing the installation and operation costs of the agitator. At the same time, a sludge discharge pipe is set at the bottom to prevent bottom sludge from accumulating at the bottom of the tank and affecting the treatment effect of the biological treatment tank. The through-hole sludge discharge pipe prevents pipe blockage or uneven water flow from causing incomplete sludge discharge. This utility model uses a guide plate flow transmission method, which reduces the initial purchase and subsequent operation costs compared to a submersible flow generator.

[0014] Reference Figures 1 to 7 A movable biological contact oxidation water tank structure includes a biological tank body 1, a packing support 5 placed in the biological tank body, and biological packing 7 uniformly filled on the packing support 5. The biochemical tank 1 can be a standard container tank or a customized steel tank, facilitating transportation by car and sea. Several sets of positive guide vanes 3 and negative guide vanes 4 are provided in the biochemical tank to act as a barrier. The positive guide vanes and the negative guide vanes are distributed alternately and evenly in the biochemical tank. The bottom of the positive guide vane is provided with a bottom water channel 31, and guide vane lifting lugs 12 are provided on both sides of the top of the positive guide vane. The top of the anti-flow guide plate is provided with a top water flow groove 41, and flow guide plate lifting lugs 12 are provided on both sides of the top of the anti-flow guide plate. To facilitate use with the inlet pipe module, the positive guide vane is positioned at the first position, and the reverse guide plate is positioned behind the positive guide vane. Another positive guide vane is then positioned behind the reverse guide plate, and so on, alternating until a positive guide vane is finally positioned near the outlet weir 9 of the biological treatment tank. Both the positive and reverse guide vanes are made of steel plates, PP plates, or other similar materials, allowing for insertion and removal within the biological treatment tank. The use of thin steel plates and PP plates reduces initial procurement and subsequent operating costs compared to submersible propellers. Furthermore, the uniform and easily portable structure of the positive and reverse guide vanes allows for placement as needed.

[0015] A sludge discharge pipe 6 is placed inside the biological treatment tank and between the forward and reverse flow plates. The sludge discharge pipe is located at the bottom of the biological treatment tank and runs through the tank. Sludge discharge pipe connectors 2 are installed at both ends of the sludge discharge pipe. The sludge discharge pipe is used to prevent bottom sludge from accumulating at the bottom of the tank and affecting the treatment effect of the biological treatment tank, and to prevent pipe blockage or uneven water discharge from causing incomplete sludge discharge. A water inlet pipe module is provided at the front end of the biochemical tank. The water inlet module includes a water inlet interface 10 located at the front end of the biochemical tank, a water inlet pipe 13 connected to the water inlet interface, and a water inlet distribution pipe 11 located at the bottom of the biochemical tank and connected to the water inlet pipe. The water inlet distribution pipe 11 has several evenly distributed water outlet holes. A biological tank outlet weir 9 is provided at the rear end of the biological tank body, and a biological tank outlet 8 is provided inside the biological tank outlet weir. The biological tank outlet weir can be a triangular weir, a rectangular weir, etc., to ensure uniform water discharge and prevent short-circuiting. refer to Figure 6 The inlet pipe module starts operating, initiating water intake and creating a flow that propels the water. Since the positive and negative guide plates are placed alternately, the water enters from the end of the biological tank and flows through the inlet interface 10, along the inlet pipe 13, into the inlet distribution pipe 11, and then out through the outlet of the inlet distribution pipe 11. Because the inlet distribution pipe 11 is located at the bottom of the tank, it needs to be used in conjunction with the positive guide plate. The water flows along the bottom groove of the positive guide plate and into the next compartment. The water flows upwards, then flows out from the top groove of the reverse guide plate into the next partition. The water flows downwards, flowing out from the bottom groove of the positive guide plate, circulating in sequence until it flows out from the bottom of the last positive guide plate. Then the water flows upwards and enters the biological treatment tank outlet weir 9 or biological treatment tank outlet 8, completing the circulation. The water is distributed evenly through pipes. A guide plate is set in the middle of the biological treatment tank to allow the wastewater to flow up and down in the biological treatment tank, so that the packing material and wastewater in the anoxic tank are fully mixed, reducing the installation and operation costs of the agitator.

[0016] The advantages of this utility model are as follows: This technical solution uses guide plates with different water outlet channels, which are evenly placed in the biological treatment tank and spaced in several groups to restrict the direction of water flow. A water distribution pipe is then installed to achieve uniform water distribution, providing the driving force for the water flow. Combined with the guide plates, this allows the wastewater to flow up and down in the biological treatment tank, ensuring thorough mixing of the packing material and wastewater in the anoxic tank, thus reducing the installation and operating costs of the agitator. Simultaneously, a sludge discharge pipe is installed at the bottom to prevent sludge accumulation at the bottom of the tank, which would affect the treatment effect of the biological treatment tank. The through-flow sludge discharge pipe also prevents pipe blockage or uneven water flow that could lead to incomplete sludge removal. Compared to submersible flow mixers, this utility model uses a guide plate-based flow transmission method, which reduces both initial procurement and subsequent operating costs.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
