A thriving economy depends heavily on the support of related industries, such as manufacturing, services, and animal husbandry. However, the development of these industries inevitably generates numerous pollutants, such as wastewater and exhaust gases. Today, let's discuss integrated wastewater treatment equipment in wastewater treatment equipment.
Integrated wastewater treatment equipment uses membrane bioreactor technology, a new process combining biological treatment technology and membrane separation technology. It replaces the secondary sedimentation tank of traditional processes, effectively separating solids and liquids to produce directly usable, stable wastewater. It also maintains a high concentration of microorganisms in the bioreactor, resulting in less excess sludge. It highly effectively removes ammonia nitrogen, with effluent suspended solids and turbidity close to zero. Effluent bacteria and viruses are significantly reduced, energy consumption is low, and the footprint is small.
Wastewater Treatment Equipment
Integrated wastewater treatment equipment is suitable for residential areas, office buildings, shopping malls, hotels, restaurants, government agencies, schools, military facilities, factories, and other similar industrial organic wastewater, such as wastewater from the textile, beer, papermaking, leather, food, and chemical industries.
Integrated wastewater treatment equipment is buried underground, and its design considers maintenance requirements. All equipment is housed in several tanks made of A3 steel plates, connected by seamless steel pipes. Both the inside and outside of the equipment are coated with chlorosulfonated polyethylene anticorrosive coating, a product promoted by the Ministry of Chemical Industry. The anticorrosive lifespan generally reaches more than 10 years.
Advantages of Integrated Wastewater Treatment Equipment:
1. High efficiency, effectively separating liquids, suspended solids, colloids, and microorganisms. Treated water does not require further processing and can be discharged directly.
2. Maintains a high concentration of biomass in the biological treatment unit, significantly increasing the volumetric load. The effectiveness of membrane separation greatly shortens the hydraulic retention time of the treatment unit, reducing the footprint of the bioreactor.
3. Prevents the loss of various microbial colonies, benefiting the growth of slow-growing bacteria (nitrifying bacteria, etc.), allowing various metabolic processes in the system to proceed smoothly.
4. Increases the retention time of some large, difficult-to-degrade organic substances, facilitating their decomposition.
5. Like other filtration and separation technologies, membrane processing technology experiences membrane clogging over time as a filtration medium. The water permeability of the membrane gradually decreases over time. Effective backwashing and chemical cleaning can slow down the decline in membrane flux, maintaining the effective service life of the MBR system.
6. Wide range of applications, strong operability, and requires no manual supervision.
