In recent years, the process of urbanization has accelerated, causing water resource pollution and serious pollution in some factories and domestic water sources. The regulations for wastewater treatment and recycling are becoming increasingly urgent. In this situation, integrated wastewater treatment equipment has become a filling strategy for centralized wastewater treatment, as traditional centralized wastewater treatment faces prominent challenges such as difficulty in wastewater collection, high investment in pipeline network projects, large land occupation, and long construction time, which seriously constrain the wastewater treatment rate and COD energy-saving and emission reduction.

What are the advantages of integrated wastewater treatment equipment compared to traditional sewage stations?

1、 Time and effort saving, indoor space saving, and cost saving

The integrated wastewater treatment equipment can be installed underground, and after the installation is completed, backfill soil can be carried out to solve the problem. The ground can be used as a garden or public green space, so the equipment does not occupy an area.

Compared with traditional buried wastewater tanks, integrated wastewater treatment equipment reduces the complex process of geological exploration, anchor rod support, waterproof curtain, deep foundation pit excavation, building steel reinforcement, formwork support, concrete pouring, and concrete maintenance, significantly reducing engineering costs and saving construction time, ensuring that the factory can be built and put into operation as soon as possible.

2、 No need for dedicated personnel to take care of, the equipment has strong stability

The supporting facilities of the integrated wastewater treatment equipment include automatic electrical equipment, automatic control system, and equipment damage alarm equipment. The equipment has good stability, so there is no need for dedicated personnel to manage it in daily operation. Only monthly or quarterly maintenance and upkeep are required.

3、 Can be used for emergency sewage treatment in sewage stations

When a sewage treatment plant experiences an unexpected situation, it is likely that the plant will have to carry out rectification and regulation for many months or even longer, and the wastewater caused by the factory cannot be sent to the wastewater treatment plant for resolution, posing a great risk of shutdown and production.

At this point, the integrated wastewater treatment equipment can fully play its emergency role and provide urgent solutions for manufacturers. The integrated wastewater treatment equipment with automatic supporting facilities can be immediately lifted and transported to the site for installation, and connected to the original wastewater tank inlet and outlet water pipeline. The integrated wastewater treatment equipment will take over the work of solving the original wastewater pool. In the short term, the sewage treatment plant cannot operate and the wastewater cannot be solved.

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

Disadvantage: In the traditional integrated wastewater treatment equipment using microbial processing technology, the separation of activated sludge and water is achieved through the action effect in the secondary sedimentation tank. The high efficiency of separation depends on the foundation settlement characteristics of activated sludge. The better the foundation settlement characteristics, the higher the efficiency of sludge separation. The settlement characteristics of the sludge foundation depend on the operation of the hydrolysis and acidification tank, which results in the inability to ensure high efficiency in wastewater treatment.

In order to better address the shortcomings 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 utilizes membrane bioreactor (MBR) processing technology, which is a new type of wastewater treatment technology that combines membrane separation equipment with biotechnology.

It uses membrane separation technology equipment to intercept the activated sludge and biomolecular organic chemical substances in the biochemical reaction tank, eliminating the need for a secondary sedimentation tank. As a result, the concentration value of activated sludge is further increased, and the retention time (HRT) and sludge retention time (SRT) of hydroelectric power generation can be controlled separately, while difficult to dissolve chemicals continue to reflect and dissolve in the tubular reactor. The membrane bioreactor (MBR) processing technology greatly enhances the role of membrane bioreactors based on membrane separation equipment.

The MBR process combines the membrane separation equipment in the separated engineering project with the traditional sewage microbial solution technology, and replaces the secondary sedimentation tank with the MBR tank, further improving the efficiency of solid-liquid separation equipment, expanding the concentration of activated sludge in the hydrolysis acidification tank, and increasing the number of animated special effect bacteria (especially beneficial bacteria) in the sludge, thereby improving the biochemical reaction speed.
