[0002] The A2O process is a commonly used sewage treatment process for medium and small domestic sewage and rural domestic sewage treatment tanks. The aerobic section is mostly treated using the activated sludge method. The activated sludge method is to continuously mix and culture sewage and various microbial communities under artificial oxygenation conditions. After a certain period of time, sludge-like flocs are formed due to the reproduction of aerobic microorganisms, forming activated sludge. The biological coagulation, adsorption and oxidation of activated sludge are used to decompose and remove organic pollutants in sewage.

[0003] The following problems exist in the existing sewage treatment tanks using the activated sludge method: the activated sludge contains scattered microbial communities, which are easily affected by changes in water quality and quantity and the local climate environment, and may be reduced or even completely killed, resulting in poor sewage treatment stability and reduced effluent water quality. Utility Model Content

The upper side wall of the box body is provided with a sewage inlet, and the lower side wall of the box body is provided with a bacterial solution outlet. The sewage inlet and the bacterial solution outlet are equipped with solenoid valves. The top cover is installed with the opening at the top of the box body. The microbial generator and the nutrient solution delivery pipe are installed on the top cover and extend into the box body.

[0006] Furthermore, an electric heating device and a temperature sensor are installed in the box.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The present application is provided with a box and a microbial generator. The box can be placed independently and the conditions in the generator can be adjusted as needed. A large number of microorganisms are generated in the generator, which can quickly replenish the sewage treatment tank. The box can reduce the impact of water quality and water quantity fluctuations and environmental changes on the microorganisms in the box. The microbial generator can provide bacterial strains, which are cultured in the box and then released into the aerobic section for sewage treatment, maintaining the stability of microorganisms in the aerobic section, and solving the problem that the existing activated sludge is a scattered microbial population, which is easily affected by changes in water quality and water quantity and the local climate environment and may be reduced or even completely killed. The present application is provided with a nutrient solution delivery pipe, an electric heating device and a temperature sensor, which can control whether aerobic microorganisms or nitrifying bacteria are mainly produced by controlling the culture temperature, time and the ratio of the carbon source in the nutrient solution, so as to enhance the treatment of sewage under different conditions.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0018] The utility model discloses an enhanced microbial generation box, see Figure 1-4An enhanced microbial generation box includes a box body 1, a top cover 2, a microbial generator 3 and a nutrient solution delivery pipe 4. The upper part of the side wall of the box body 1 is provided with a sewage inlet 11, and the lower part of the side wall of the box body 1 is provided with a bacteria solution outlet 12. The sewage inlet 11 and the bacteria solution outlet 12 are equipped with solenoid valves. The top cover 2 is installed with the opening on the top of the box body 1, and the microbial generator 3 and the nutrient solution delivery pipe 4 are installed on the top cover 2 and extend into the box body 1.

[0019] The bacteria produced by the microbial generator 3 installed on the top cover 2 can be cultured in the box 1. The sewage inlet 11 can be introduced into the sewage of the aerobic section as a culture environment for the bacteria. The bacterial liquid outlet 12 can discharge the cultured bacterial liquid to replenish the aerobic section when the aerobic section needs to replenish microorganisms. The nutrient solution delivery pipe 4 can be used to add nutrient solution to cultivate the bacteria. By controlling the proportion of the carbon source added to the nutrient solution, it is controlled whether aerobic microorganisms or nitrifying bacteria are mainly produced.

[0020] See Figure 1-4 An electric heating device 5 and a temperature sensor 6 are installed in the box 1. The electric heating device 5 and the temperature sensor 6 can be connected to the controller of the sewage treatment tank to control the culture temperature of the bacteria in the box 1 to avoid the influence of low environmental temperature on the culture of bacteria.

[0021] See Figure 1-4 The microbial generator 3 is columnar, and generating holes 31 are evenly opened on the shell of the microbial generator 3. A bacterial strain fixing carrier 33 is installed inside the microbial generator 3. The microbial generator 3 is provided with an air inlet pipe 32 connected to the shell. The air inlet pipe 32 can be connected to the biological aeration device of the sewage treatment tank to diffuse the bacterial strain fixed on the bacterial strain fixing carrier 33 into the box 1 through the generating holes 31 through aeration.

[0022] See Figure 1-4 The top cover 2 is provided with a hanging ring 21 to facilitate the installation of the box body 1 in the sewage treatment tank.

[0023] Working process:

[0024] The box body 1 is installed in the aerobic section of the sewage treatment tank through the hanging ring 21, the nutrient solution delivery pipe 4 on the top cover 2 is connected to the outside of the sewage treatment tank, the air inlet pipe 32 is connected to the aeration device, and sewage is discharged through the sewage inlet 11 as a culture environment. The bacteria in the microbial generator 3 are diffused into the box body 1 by inflation through the air inlet pipe 32. The culture temperature, time and proportion of the carbon source in the nutrient solution are controlled. When the aerobic section needs to supplement the bacteria, the cultured bacteria solution is discharged into the aerobic tank through the bacteria solution outlet 12 to maintain the stability of the microorganisms.
