In those years, the integrated water treatment equipment we missed~

With the development of my country’s economy and the advancement of urbanization, the shortage of water resources and the aggravation of water pollution are becoming more and more serious, and the requirements for sewage treatment and reuse are becoming more and more urgent. Due to the outstanding problems of traditional centralized sewage treatment, such as difficult sewage collection, high investment in pipeline network, large area and long construction period, the sewage treatment rate and COD emission reduction are seriously restricted. In this case, integrated wastewater treatment equipment It becomes a supplementary measure for centralized sewage treatment. So, compared with traditional wastewater stations, what are the advantages of integrated wastewater treatment equipment?

1. Save time, space and cost

The integrated wastewater treatment equipment can be installed in the ground. After the equipment is installed, it will be backfilled. The surface can be used as greening or square land, so the equipment does not occupy any surface area.

Compared with the traditional buried sewage pool, the integrated wastewater treatment equipment has reduced the complex procedures such as geological survey-support-waterproof curtain-digging the foundation pit-tying the steel bar-supporting the formwork-pouring the concrete-curing the concrete. The engineering cost is reduced, the construction time is saved, and the factory can be put into production as soon as possible.

2. There is no need for special care, and the equipment is highly reliable

The “integrated wastewater treatment equipment” is equipped with a fully automatic electrical control system and an equipment damage alarm system. The equipment has good reliability. Therefore, there is no need for special personnel to manage the daily operation, and it only needs to be maintained and maintained on a monthly or quarterly basis.

3. Can be used for emergency treatment of wastewater in sewage stations

When an emergency occurs in a sewage treatment station, it may take several months or longer for the sewage treatment station to be rectified and debugged. The wastewater generated by the factory cannot enter the sewage station for treatment, and the factory faces a huge risk of shutdown and production.

At this time, the integrated wastewater treatment equipment can play its emergency role and solve the urgent need for manufacturers. The integrated wastewater treatment equipment with fully automatic facilities can be directly hoisted to the site for installation and transferred to the original sewage tank inlet and outlet pipes. The integrated wastewater treatment equipment will take over the treatment of the original sewage tank. Solve the dilemma that the sewage treatment station cannot be operated, and the sewage cannot be treated in a short time.

Compared with traditional wastewater stations, integrated equipment has many advantages, but traditional integrated wastewater treatment equipment also has disadvantages.

Disadvantages: In the biological process adopted by the traditional integrated wastewater treatment equipment, the separation of activated sludge and water is completed by gravity in the secondary sedimentation tank, and the separation efficiency depends on the sedimentation performance of activated sludge. The better the sedimentation performance, The higher the mud-water separation efficiency. The sedimentation performance of the sludge depends on the operating conditions of the aeration tank, resulting in that the wastewater treatment efficiency cannot be guaranteed to be in a high-efficiency state.

In order to solve the drawback of traditional integrated wastewater treatment equipment, new MBR integrated wastewater treatment equipment has been widely used in wastewater treatment in recent years.

New integrated wastewater treatment equipment

The MBR integrated wastewater treatment equipment uses the membrane bioreactor (MBR) process, which is a new wastewater treatment technology that organically combines membrane separation technology and biotechnology.

It uses membrane separation equipment to retain the activated sludge and macromolecular organic substances in the biochemical reaction tank, saving the secondary sedimentation tank. Therefore, the concentration of activated sludge is greatly improved, and the hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, while the refractory substances are continuously reacted and degraded in the reactor. The membrane bioreactor (MBR) process greatly enhances the function of the bioreactor through membrane separation technology.

The MBR process organically combines the membrane separation technology in the separation project with the traditional wastewater biological treatment technology and uses the MBR tank to replace the secondary sedimentation tank, which greatly improves the solid-liquid separation efficiency, and increases the concentration of activated sludge in the aeration tank. The special bacteria (especially the dominant flora) in the mud increased, which improved the biochemical reaction rate.

Technical advantages:

The membrane reactor has a strong separation effect, and can effectively separate colloids, suspended solids, biological flora and other substances from sewage, replace processes such as precipitation and filtration, and improve water quality and stability.
The strong interception ability can limit the biological flora in the reaction tank, increase the sludge content and hydraulic retention time, make the reaction tank biochemical effect better and the system control more stable.
The equipment can effectively filter harmful microorganisms in sewage, such as viruses and bacteria, which not only saves the cost of sewage disinfection, but also facilitates the secondary reuse of sewage.
