Submerged membrane bioreactor is a new type of water treatment equipment that combines membrane technology and bioreactor.Its characteristics and advantages are as follows：

1. The submerged membrane bioreactor adopts membrane technology, which can effectively separate suspended solids, colloidal substances and microorganisms in the water, improve the efficiency of water treatment, and reduce the treatment time and energy consumption.

2. Space saving: Compared with traditional bioreactors, submerged membrane bioreactors are small in size and cover a small area. They are suitable for water treatment in a limited space, saving land resources.

3. Strong adaptability: Submerged membrane bioreactors are suitable for water treatment processes of different water quality and treatment scales. They can effectively remove organic matter, nitrogen, phosphorus and other pollutants from the water, and have good adaptability.

4. Easy to operate: The submerged membrane bioreactor has a simple structure and easy operation. It does not require excessive equipment and manpower maintenance, which reduces operating costs and management costs.

5. High effluent quality: The submerged membrane bioreactor adopts microporous membrane technology, which can effectively filter microorganisms and particulate matter in the water, ensuring the stability and safety of the effluent quality.

6. Strong pollution resistance: The submerged membrane bioreactor has a smooth surface, is not easy to be contaminated, has good anti-pollution properties, and extends the service life of the membrane.

7. Sustainable development: The submerged membrane bioreactor adopts biodegradable technology, which can effectively reduce the use of chemicals, is in line with the concept of sustainable development and is environmentally friendly.
