MBR의 특징

시간 : 2020-04-15 조회수 : 50

Compared with traditional water treatment methods, MBR has the following obvious features:


1. MBR은 미생물을 하수에 효과적으로 포획 할 수 있으며 슬러지 나이와 유압 유지 시간의 분리를 실현합니다. 슬러지 나이의 크기를 조정함으로써 질화 박테리아 및 탈질 박테리아와 같은 긴 성장주기를 가진 미생물도 우세한 박테리아가 될 수 있으며, 어느 정도 반응기 전체의 질소 제거 효율을 향상시켜 작업을보다 유연하게 할 수 있습니다 그리고 안정적입니다.

 


2. MBR has high solid-liquid separation efficiency, good and stable effluent effect, and little effect on the quality of influent water. Due to the high-efficiency trapping effect of the membrane, larger particles, organic molecules and bacteria in the reactor are trapped on the water inlet side of the membrane. At the same time, there is no need to consider sludge expansion.

 

3. The sludge concentration is high and the remaining sludge output is small. MBR can be operated under the conditions of high volume load and low sludge load, and the remaining sludge output is low, which greatly reduces the subsequent treatment costs.

 

4. The MBR reactor has a compact structure and concentrated process equipment, so it occupies a small area, and it is easy to realize integrated automatic control and convenient operation and management.

 


Although MBR has the above characteristics, it also has disadvantages, such as serious membrane pollution, low oxygen utilization rate, high investment cost, high energy consumption for water treatment, and chemical cleaning waste liquid will cause secondary pollution. In practical applications, membrane fouling is the biggest limiting factor affecting the promotion of MBR.
