MBR membrane bioreactor：
The active sludge and macromolecular organics were mainly used in the interception tank of the membrane separation equipment.
The concentration of activated sludge (MLSS) in membrane bioreactor can be increased to 8000 ~ 10,000 mg/L, or even higher.
Sludge age (SRT) can be extended to more than 30 days.
Interception of membrane bioreactor due to its effective role, may retain generation cycle longer microbes, which can realize on the depth of water purification, denitrifying bacteria in the system can fully reproduce at the same time, the nitrification effect is obvious, the depth of possible biological nutrient removal.
Process and Function introduction：
MBR is an efficient combination of membrane separation technology and biological treatment method. Its origin is to replace the two sinks in activated sludge method with membrane separation technology, and the solid liquid separation is carried out.
This process not only effectively achieves the purpose of the separation of mud and water, but also has the advantages of the three-stage treatment of the traditional process of sewage treatment.
1, efficiently for solid-liquid separation, the separation effect is far better to the traditional sedimentation tank, the water quality is good, the effluent suspended solids and turbidity was close to zero, can be directly reuse, realize the wastewater reuse.
2. The efficient interception of membrane allows the microorganism to be completely trapped in bioreactor, to realize the complete separation of the reactor hydrostatic time (HRT) and the sludge age (SRT), and the operation control is flexible and stable.
3. Since the MBR has integrated the aeration pool of traditional sewage treatment with the sink pool and replaced the whole process facilities of the tertiary treatment, it can significantly reduce the floor area and save the land investment.
4. For the retention and reproduction of nitrifying bacteria, the system nitrification efficiency is high.
The removal of ammonia and phosphorus removal can also be performed by means of operation.
5. Since the age of mud can be very long, it can greatly improve the degradation efficiency of refractory organics.
6. The reactor is operating under high volume load, low sludge load and long mud age, and the output of residual sludge is extremely low. Due to the infinite length of mud age, it can theoretically achieve zero sludge discharge.
7. PLC control system and convenient operation and management
The liquid mixture is separated by selective filtration by microfiltration membrane, and the separation, concentration and purification are achieved by intercepting liquid mixture under the operating pressure range.
At present, continuous ultrafiltration technology is widely concerned and used by the market and users, and is a mature technology.
The company's polypropylene fiber membrane components have rich experience in water purification, river water, deep well water and industrial process.
In the membrane system, the original water is on the outside of the membrane, and the inside of the membrane is purified, the reflux ratio is high, the water flow in the membrane tube is large, which is conducive to reducing the membrane fouling.
Mix air water backwashing process at the same time, through the air scrubbing the membrane surface, can effective protective membrane element, membrane cleaning effect is good, can effectively remove the impurities such as bacteria, microbes and suspended solids in the water, the water turbidity near zero...
As a pretreatment of RO and NF, the RO and NF waterlogged SDI are 2, greatly extending the service life of RO and NF membrane elements and ensuring the stable operation of the membrane system for a long time.
On-line cleaning, combined with the fine mechanical properties of membrane material, can adopt gas-water backwash technology and the wrong flow process, the area is small.
Traditional methods need complicated process to achieve RO, NF water requirements, CMF only step filter can get high quality water pretreatment, directly as water RO, NF, water production rate is above 95%.
Low cost of investment.
Reduce the cost of pre-processing equipment and agents.
Prolong the cleaning cycle of RO and NF.
The cleaning cycle of RO and NF has been extended from 1 to 3 months to more than half a year, and the life span is extended from 2 to 3 years to more than 5 years.
Automatic control and remote monitoring can be realized
