The application of sewage mixer in the sewage treatment industry is mainly reflected in the following aspects:

First, application background and purpose

Sewage treatment is an important link in protecting water resources and improving ecological environment. As one of the key equipment in the sewage treatment system, the sewage mixer promotes the contact between the impurities in the sewage and the treatment agent or microorganisms through the stirring action, accelerates the biochemical reaction process, and improves the efficiency and quality of sewage treatment.

Second, application program overview

Equipment selection

According to the treatment scale, treatment process and water quality standards and other factors, choose the appropriate type and specification of sewage mixer. Common sewage mixers include submersible mixers, vertical mixers, side mixers and so on.

Considering the speed, power, flow field distribution and other characteristics of the mixer, it ensures that the equipment can meet the processing needs and achieve energy saving and consumption reduction.

Process design

The sewage mixer is integrated into the sewage treatment process, usually used in the primary treatment stage or in conjunction with other treatment units.

Reasonable stirring time and stirring intensity are designed to ensure that impurities in sewage can be fully mixed and reacted.

System integration and control

The sewage mixer is integrated with other equipment of the sewage treatment system (such as pumps, valves, pipes, etc.) to achieve automatic control and remote monitoring.

Equipped with necessary monitoring instruments and control systems, real-time monitoring of water quality changes and equipment operating status, to ensure stable operation of the system.

Third, specific application scheme

Hydraulic circulation

A submersible mixer is installed in the anaerobic pool, anoxic pool and oxidation ditch, and a continuous circulating water flow is formed through the stirring action to keep the mixed liquid in the pool in suspension state.

This design can not only effectively keep the mixture suspended, but also improve the diluting and equalizing capacity of the water flow in the pool and withstand the impact load.

Improve oxygen transfer efficiency

The aeration tank is designed as a continuous circulation flow tank by using a submersible mixer. The energy input through the agitator changes the bubble path, increases the "oxygen water depth", and improves the oxygen transfer efficiency.

This design can generally improve the oxygen transfer efficiency of the aeration system by about 15%, and reduce the energy consumption and operating costs of sewage treatment.

Promote biochemical reaction

In the biological treatment unit, the sewage mixer promotes the full contact between microorganisms and the substrate through the stirring action, and accelerates the biochemical reaction process.

It is suitable for reaction pool, mixing pool in physicochemical treatment process and selection pool and anaerobic pool in biological treatment system.

Improve water quality

A submersible mixer is set up in the polluted water body with large water depth and slow water flow or the deep treatment pond of sewage treatment for "artificial respiration" to re-oxygenate the deep water area.

This technology can improve the water quality of the whole water body, increase the dissolved oxygen content, and promote the ecological restoration of the water body.

Fourth, precautions and maintenance

When using the sewage mixer, the operating status and mixing effect of the equipment should be checked regularly to ensure the normal operation of the equipment.

Pay attention to the maintenance of the equipment, including cleaning equipment, replacing worn parts, filling lubricants, etc.

The water quality is monitored and analyzed regularly, and the operating parameters and process flow of the mixer are adjusted according to the water quality changes.

In summary, the application scheme of sewage mixer in the sewage treatment industry needs to comprehensively consider equipment selection, process design, system integration and control and other aspects. Through scientific and reasonable application scheme design and fine operation management, the role of sewage mixer can be fully brought into play, and the efficiency and quality of sewage treatment can be improved.
