Based on the present situation of water resources' shortage in our country and the social requirement for sewage treatment, our company did a lot of researches about the sewage treatment and developed the MBR method which features advanced technology, easy installation and operation. The characteristics are as follows:
The membrane separation process of the advanced membrane bioreactor method takes the place of the traditional biological treatment, gravity settling process, thus, make the effect better, the effluent is more stable, can be reused directly.
Simple technological process. The membrane bio-react tank displaces the traditional contact oxidation tank, sedimentation tank, middle tank. The process is easy to control. The membrane bioreactor adopts the integrated design, it has a compact structure, small floor occupation and high automaticity.
Hardly need sludge discharge. Because the device can work with the sludge concentration above 10g/l, COD can be thoroughly biodegraded in the MBR tank which is with high sludge concentration. Therefore, there is little excess sludge.
The machine can realize automatic intermittent operation. The system pumps and valves can start and open as the designed procedure automatically. It is equipped with automatic level control, membrane pollution control and failure warning control for easy observation.
The device is suitable for residential district, multifunctional building, hotels, restaurants, apartment, bath center, etc, esp. The domestic sewage. The water being treated can be reused as flushing water, greening water, landscape water and undrinkable water.
The raw sewage enters into the septic tank and regulating tank. It is equipped with a grille in front of the regulating tank which is used to intercept the big particles and hair. Then sewage pumps into the reaction tank by the lifting pump, with the help of aeration, water circularly flows up and down in the reactor, which makes the membrane silk shake to reduce the membrane pollution and provide enough oxygen for the active sludge to remove the organic pollutants. By the effective function of membrane's separation and filtration, the device can effectively remove SS, particles and colibacillus. After disinfection, the water can be stored in the clean water tank to be reused as flushing water, greening water, etc.
1) Long lifetime
2) Totally enclosed operation
3) Suitable for treating infectious waste
4) Avoid secondary pollution
5) Simple operation
