MBRintegrationSewage treatment equipmentSeveral characteristics in the field of sewage treatment, compared with many traditional biological water treatment processes, have the following main features:

　　1High quality and stable effluent water quality

Due to the efficient separation effect of the membrane, the separation efficiency is much better than that of traditional sedimentation tanks. The treated effluent is extremely clear, with suspended solids and turbidity close to zero. Bacteria and viruses are greatly removed, and the effluent quality is better than that of constructionThe water quality standards for domestic miscellaneous water issued by the Ministry (CJ25.1-89) can be directly reused as non potable municipal miscellaneous water.

At the same time, membrane separation also completely intercepts microorganisms in the bioreactor, enabling the system to maintain a high concentration of microorganisms. This not only improves the overall removal efficiency of the reaction device for pollutants, but also ensuresIt has been proven that the effluent quality is good, and the reactor has good adaptability to various changes in the inlet load (water quality and quantity), is resistant to shock loads, and can stably obtain high-quality effluent quality.

2、 Low production of surplus sludge

This process can operate under high volume load and low sludge load, with low residual sludge production (theoretically achieving zero sludge discharge), reducing sludge treatment costs.

3、 Small footprint, not limited by the setting location

　　bioreactorIt can maintain a high concentration of microbial biomass, with a high volumetric load on the treatment device and a large footprint, resulting in significant cost savings; This process is simple, compact in structure, and occupies a small area, and is not limited by the location of installationSuitable for any occasion, it can be made into ground, semi underground, and underground types.

4、 Can remove ammonia nitrogen and difficult to degrade organic matter

Due to the complete interception of microorganisms in the bioreactor, it facilitates the retention and growth of slow proliferating microorganisms such as nitrifying bacteria, thereby improving the nitrification efficiency of the system. At the same time, it can increase some difficulty to reduceThe hydraulic retention time of organic matter in the system is beneficial for improving the degradation efficiency of recalcitrant organic matter.

5、 Convenient operation and management, easy to achieve automatic control

This process achieves complete separation of hydraulic retention time (HRT) and sludge retention time (SRT), with more flexible and stable operation control. It is a new technology that is easy to equip in sewage treatment and can achieve microAutomatic machine control makes operation and management more convenient.

6、 Easy to transform from traditional craftsmanship

This process can serve as a deep treatment unit for traditional sewage treatment processes, and has broad applications in areas such as deep treatment of effluent from urban secondary sewage treatment plants (thereby achieving large-scale reuse of urban sewage)Prospect.

　　membrane bioreactorThere are also some shortcomings. Mainly manifested in the following aspects:

1. The high cost of membranes results in higher infrastructure investment for membrane bioreactors compared to traditional wastewater treatment processes;

2. Membrane fouling is prone to occur, causing inconvenience to operation and management;

3. High energy consumption: Firstly, the MBR sludge water separation process must maintain a certain membrane driving pressure. Secondly, the MLSS concentration in the MBR tank is very high. To maintain sufficient oxygen transfer rate, it is necessary to increase aeration intensity. In order to increase membrane flux and reduce membrane fouling, it is necessary to increase flow rate and flush the membrane surface, resulting in higher energy consumption of MBR compared to traditional biological treatment processes.
