Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a reactor for sewage biological treatment which is convenient for adjusting temperature. Background Art

[0002] With the continuous development of cities in my country, various complexes, enterprise and institution canteens, school canteens, hotels, food cities and other places with large catering food courts have also increased. Kitchen wastewater contains food waste and slop, which contain a large amount of animal and vegetable oils. If food waste and slop are directly discharged into the sewer without treatment or illegally discharged, a large amount of oil will adhere to the pipe wall, causing problems such as reduced flow capacity and blockage in the sewer. Since kitchen wastewater contains a large amount of organic matter, in order to prevent sewage pollution and achieve harmless discharge of sewage, it is necessary to biologically treat the sewage to reduce the organic content in the sewage so that it meets the discharge standards. Biological treatment of sewage is the use of biological methods to treat sewage. It is one of the most widely used methods in modern sewage treatment and the main way to treat urban domestic sewage. The reactor is one of the main equipment for biological treatment of sewage. The sewage has microorganisms that react biologically in the reactor to reduce the organic content in the sewage.

[0003] However, some existing reactors for biological treatment of sewage do not have temperature regulating components. The temperature of the reactor needs to be adjusted by adding hot water or cold water into the reactor. The operation is cumbersome and inconvenient to use. Some reactors have temperature regulating components, and their heating or cooling components are arranged inside the reactor. The sewage reaction temperature is adjusted by directly heating or cooling the sewage. The above two methods will cause the temperature of a certain part of the sewage to rise or fall instantly when heating, and then gradually balance. In the process of instantaneous heating or cooling of the sewage, the microorganisms in the area will die due to high or low temperature, affecting the biological treatment of the sewage. In addition, heating or cooling by regional heating or cooling mapping will cause uneven changes in the sewage temperature, thereby causing an imbalance of the organisms in the reactor and affecting the sewage treatment effect. The practicality is poor. Utility Model Content

After the mixing is completed, the reaction temperature inside the box 1 is adjusted according to the temperature required for the biological treatment of the sewage. When the temperature is adjusted, the electric heating block 3 heats the temperature-controlled water in the temperature-controlled tank 2. As the temperature of the temperature-controlled water increases, the box 1 is gradually heated and heated, thereby increasing the reaction temperature of the box 1. When the temperature of the box 1 is too high and needs to be cooled, the water pump 8 pumps the temperature-controlled water in the temperature-controlled tank 2 into the cooling box 4 through the connecting pipe 5. The condensing agent in the cooling box 4 cools down the temperature-controlled water flowing in the threaded tube 7. The threaded tube 7 increases the residence time of the temperature-controlled water in the cooling box 4 and improves the cooling effect.

[0025] like Figure 3 As shown, a heat-insulating pad 11 is arranged on the outer wall of the box 1. The heat-insulating pad 11 is matched with the box 1. The thickness of the heat-insulating pad 11 is less than the thickness of the box 1. The heat-insulating pad 11 is made of heat-insulating silica gel. The heat-insulating pad 11 insulates the box 1 to prevent the temperature of the box 1 from being affected by the external environment.

[0026] like Figure 3As shown, a rotating shaft 12 is rotatably installed on the inner wall of the top of the box 1, and stirring rollers 13 are arranged on the outer wall of the rotating shaft 12 at equal distances. A cleaning block 14 is welded on the outer wall of the rotating shaft 12. The cleaning block 14 is arc-shaped and matched with the box 1. A cleaning pad 15 matched with it is arranged on the outer wall of the cleaning block 14. The rotating shaft 12 is matched with the temperature control tank 2. A servo motor 16 is installed on the outer wall of the top of the box 1 by bolts. The output shaft of the servo motor 16 is connected with the rotating shaft 12.

[0028] During operation, the sewage is injected into the box 1 through the feed pipe 17, and then the microorganisms required for biological treatment are poured into the box 1 through the filling port, and then the microorganisms are mixed with the sewage.

When the temperature is adjusted, the electric heating block 3 heats the temperature-controlled water in the temperature-controlled tank 2. As the temperature of the temperature-controlled water increases, the box 1 is gradually heated and heated, thereby increasing the reaction temperature of the box 1. When the temperature of the box 1 is too high and needs to be cooled, the water pump 8 pumps the temperature-controlled water in the temperature-controlled tank 2 into the cooling box 4 through the connecting pipe 5, and the cooling box The condensing agent in 4 cools the temperature-controlled water flowing in the threaded tube 7, and the threaded tube 7 increases the residence time of the temperature-controlled water in the cooling box 4, thereby improving the cooling effect.

The insulation pad 11 keeps the box 1 warm to prevent the temperature of the box 1 from being affected by the external environment;

[0030] After the microorganisms required for biological treatment of sewage are poured into the box 1, the servo motor 16 drives the rotating shaft 12 to rotate and drives the stirring roller 13 to stir the sewage, so that the microorganisms and sewage are mixed more evenly. As the rotating shaft 12 rotates, the cleaning block 14 rotates to wipe the inner wall of the box 1 to prevent impurities in the sewage from adhering to the inner wall of the box 1, thereby keeping the box 1 clean and facilitating cleaning of the box 1.
