Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to biochemical equipment for treating wastewater from a power plant. Background Art

[0002] Thermal power plants rely on water as a medium for transferring energy and as a cooling medium for heat exchange during operation. Water plays an important role in thermal power plants. In the process of thermal power plants, water mainly has two circulation systems: one is the water vapor circulation system in the power equipment; the other is the cooling water circulation system. Therefore, power plants are not only large users of water and drainage, but also large polluters. Although the content of pollutants in the wastewater of thermal power plants is not large, due to the large amount of drainage, the total amount of pollutants discharged also increases accordingly, which will cause varying degrees of environmental pollution.

[0003] The authorization publication number "CN220034066U" records "a power plant sewage treatment device, including a first box body, a second box body is fixedly connected to the surface of the first box body, a through hole is opened on the surface of the second box body, a movable plate is arranged in the through hole, a filter box is fixedly connected to the surface of the movable plate, and a groove is opened on the inner wall of the through hole. By setting a first rotating shaft and a threaded column, when people need to move the filter box, they only need to rotate the turntable through external tools, so as to drive the first rotating shaft to rotate, and then drive the threaded column to rotate. Under the joint action of the threaded column and the threaded tube, the clamping rod can be driven to move, and then the clamping rod can be separated from the clamping groove, so as to move the movable plate, and then the filter box can be moved out of the second box body, and the dirt in the filter box can be cleaned, so that people can move the filter box more quickly."

[0004] The above patent can clean the dirt in the filter box, so that people can move the filter box more quickly. However, it cannot be fully treated during use. In order to reduce costs, reduce environmental pollution, optimize the wastewater treatment process and technology of power plants, realize wastewater resource utilization, and reuse wastewater until zero emission, explore new treatment models and improve social and economic benefits.

[0028] There are two groups of defoaming mechanisms, both of which are arranged in the biochemical reaction tank 1 to eliminate bubbles in the biochemical reaction tank 1. Each group of defoaming mechanisms includes a defoaming pipe 6 and a high-pressure gas pump 3. The high-pressure gas pump 3 is fixedly connected to one side of the inner wall of the biochemical reaction tank 1 near the top, and the defoaming pipe 6 is fixedly connected to the output end of the high-pressure gas pump 3.

[0029] In this embodiment: the filler 7 is a three-dimensional structure, with a large contact area with pollutants, good suspension, and the density of the filler 7 after immersion in water is close to the density of water, so it can be suspended in water. During aeration, it is completely mixed with water, and the environment for microbial growth is a three-phase gas, liquid, and solid. The filler 7 is an elastic material, which helps the aging sludge to fall off. The filler 7 has a high porosity and a large specific surface area, and microorganisms are easy to attach. The porosity is 99%, and the specific surface area is greater than 6000m 2 / m 3 The porous surface of the filler 7 is easy to adhere to tiny bubbles, which helps the bottom carrier and the upper carrier to circulate alternately. The microbial population on the filler 7 is larger than that of similar fillers 7, and the treatment efficiency is high. The water stays in the biochemical pool for a short time, only half of that of similar processes. Due to the short residence time, when treating the same amount of water, the structure is small and the floor space can be saved by half. The aeration system adopts a perforated aeration pipe system, which is not easy to be blocked. A stirring mechanism is provided inside, which is provided in the application of the prior art and will not be described in detail here. The defoaming pipe 6 and the high-pressure gas pump 3 eliminate internal bubbles to avoid excessive internal bubbles and ensure the use effect.

[0031] In this embodiment, the air inlet 4 and the connecting pipe 5 cooperate and are used as a whole to allow external air to enter the interior for treatment.

[0032] Specifically, a water inlet pipe 2 is installed on one side of the top of the biochemical reaction tank 1 , and a water outlet pipe 12 is connected to one side of the water outlet tank 11 .

[0033] In this embodiment: the water inlet pipe 2 cooperates with the water outlet pipe 12 to allow the water to be treated for use.

[0034] Specifically, a plurality of water outlet intercepting grids 9 are fixedly connected to one side of the inner wall of the biochemical reaction pool 1 . The plurality of water outlet intercepting grids 9 are evenly distributed, and the plurality of water outlet intercepting grids 9 are all connected to the water outlet pool 11 .

[0038] When in use, waste water is poured into the biochemical reaction tank 1 through the water inlet pipe 2, and is treated through the internal filler 7. At the same time, the air inlet 4 controls the external air to enter the connecting pipe 5, so that the aeration pipe 8 is aerated. After the treatment is completed, the water enters the water outlet pool 11 through the water outlet interception grid 9, and is separated by the partition plate 10. After completion, it is discharged through the water outlet pipe 12 to ensure use.
