Customization of MBR integrated sewage treatment equipment

Customization of MBR integrated sewage treatment equipmentWorking mechanism:

The working mechanism is based on the combination of biofilm reactors and membrane separation technology. It includes two parts: a bioreactor and a membrane separation unit.

1. Bioreactor: Wastewater first passes through a bioreactor, which contains activated sludge. In a bioreactor, organic matter in wastewater is degraded by microorganisms into inorganic matter, while microorganisms also grow and reproduce. This process is called biodegradation, which can effectively remove organic matter and nutrients such as nitrogen and phosphorus from wastewater.

2. Membrane separation unit: The wastewater treated by the bioreactor enters the membrane separation unit, which includes a microporous membrane. Micro porous membranes have smaller pore sizes and can effectively intercept suspended solids, bacteria, viruses, and other small particles in wastewater, while separating clear water to form effluent. This process is called membrane separation, which enables the recovery and reuse of high-quality water.

Customization of MBR integrated sewage treatment equipmentKey points for use

Operating standards:

Operators need to be proficient in the process principles of membrane bioreactors, familiar with designing parameters such as tank capacity, flow rate, and load.

Correctly operate the equipment in the MBR tank (such as underwater agitator, impeller, internal reflux pump, etc.), adjust the reflux ratio and dissolved oxygen range according to process requirements.

Water quality monitoring:

Regularly observe the biological phase of activated sludge, the transparency of the supernatant, the color of the sludge, and test indicators such as SV30, SVI, and mixed liquid filtration.

Reasonably adjust the operating parameters of the equipment based on the inlet water quality, pollutant concentration, and sludge concentration.

Environmental adaptation:

In low-temperature environments, it is advisable to extend aeration time, increase sludge concentration, or increase sludge age appropriately to ensure treatment effectiveness.

Timely clear the accumulated water or ice and snow in the pool walkway during rainy and snowy weather to ensure the safe operation of the equipment.

Maintenance skills

Daily inspection:

Check whether the surrounding environment of the equipment is clean, whether the inlet and outlet valves are normal, and whether the auxiliary equipment such as water pumps and fans are running well.

Regularly check whether the membrane components are intact, and replace them promptly if they are damaged.

Membrane module cleaning:

Physical cleaning: backwash once every three months to maintain the normal flux of membrane elements through online backwashing and aeration cleaning.

Chemical cleaning: Use sodium hypochlorite and citric acid for chemical cleaning every 3-6 months to effectively extend the service life of the membrane.

Sludge management:

Adjust the remaining sludge discharge based on the settling ratio, concentration, and nitrogen phosphorus treatment effect of the mixed liquid sludge to maintain stable sludge concentration in the membrane tank.

Regularly clean the impurities inside the filter to prevent blockage.

Equipment maintenance:

Fans and other equipment should have their oil replaced approximately every six months to extend their lifespan.

Regularly inspect the electrical control system to ensure proper operation of the equipment.
