Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a microbial additive device for microbial wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the removal of pollutants from water through physical, chemical, and biological methods to meet discharge or reuse standards. Microbial wastewater treatment is a method that utilizes the biodegradation of microorganisms to transform organic pollutants, nutrients, and other contaminants in wastewater into harmless substances. It is one of the most commonly used and effective technologies in wastewater treatment. Microorganisms have a strong degradation capacity and can effectively remove organic pollutants. The microbial treatment process is natural and sustainable, meets environmental protection requirements, and has lower energy consumption and long-term operation and maintenance costs compared to physical and chemical treatment methods. Through biodegradation, it reduces the generation of harmful substances.

[0003] When treating wastewater with microorganisms, conventional microbial dosing devices struggle to evenly distribute microorganisms within the wastewater tank. The microbial content varies significantly at different heights and locations, making it difficult to effectively purify water bodies with low microbial concentrations. This results in low wastewater treatment efficiency. Furthermore, some microbial raw materials require dilution before addition, which is difficult to achieve with conventional devices. Additionally, continuous microbial dosing is challenging, requiring significant time investment. To address these issues, a novel microbial dosing device for wastewater treatment is proposed.

This device solves the problems of current methods for treating wastewater with microorganisms, such as difficulty in uniformly adding microorganisms to the wastewater tank, significant differences in microbial content at different heights and locations, difficulty in effectively purifying water bodies with low microbial content, low wastewater treatment efficiency, the need for dilution of some microbial raw materials before addition, difficulty in fully mixing raw materials with conventional microbial additive devices, and the difficulty in continuously adding microorganisms, which can lead to time-consuming multiple additions.

The output end of the stirring motor passes through the rear side of the mixing tank and is fixedly connected to a rotating rod. The front end of the rotating rod is rotatably connected to the front side plate of the mixing tank. Several stirring rods are fixedly connected to the surface of the rotating rod.

[0006] Preferably, the nozzle is equipped with a control valve inside.

[0007] Preferably, a guide rod is fixedly connected inside the rear slide groove, and the sliding frame is slidably connected to the surface of the guide rod through a perforation.

A microbial additive 17 is fixedly installed inside the left side of the front slide groove 2. A rotating support 7 is provided. The left end of the drive threaded rod 6 passes through the right side of the sliding frame 3 and is rotatably connected to the inside of the rotating support 7. A mixing box 8 is fixedly connected at the upper center of the sliding frame 3. A stirring motor 801 is fixedly installed on the rear side of the mixing box 8. The output end of the stirring motor 801 passes through the rear side of the mixing box 8 and is fixedly connected to a rotating rod 802. The front end of the rotating rod 802 is rotatably connected to the front side plate of the mixing box 8. Several stirring rods 803 are fixedly connected to the surface of the rotating rod 802 to effectively dilute the microorganisms and make the distribution of microorganisms more uniform during continuous addition of microorganisms.

[0019] An air pump 9 is fixedly installed on the upper front end of the sliding frame 3. A pressurization pipe 10 is fixedly connected to the output end of the air pump 9. The end of the pressurization pipe 10 passes through the upper side of the mixing tank 8 and communicates with the interior of the mixing tank 8, ensuring that microorganisms can be evenly added to the sewage tank 1. A feed hopper 11 is fixedly connected to the upper center of the mixing tank 8. A first solenoid valve 12 is fixedly installed on the lower end of the surface of the feed hopper 11. A main infusion pipe 13 is fixedly connected to the front and rear sides of the interior of the sliding frame 3. A connecting pipe 14 is fixedly connected to the lower center of the sliding frame 3.

The air pump 9 delivers compressed gas to the mixing tank 8 to increase the pressure inside the mixing tank 8. The second solenoid valve 15 is opened. Microorganisms with a certain pressure and sufficient dilution enter each infusion branch pipe 16 through the infusion main pipe 13. After the pressure exceeds the threshold of the control valve inside the nozzle 17, the microorganisms will be released into the water body at different heights. At the same time, the drive motor 5 rotates to drive the threaded rod 6, the sliding frame 3 and each nozzle 17 to move in a uniform linear motion in the left and right directions, ensuring that the microorganisms are added to each position in the sewage tank 1, thereby improving the working efficiency of microbial sewage treatment.
