Containerized MBR Membrane Type Sewage Treatment Equipment for Domestic Wastewater Treatment

   MBR compact sewage treatment equipment is a combined process that combines biological treatment with membrane separation. Hollow fiber membrane modules are placed in the integrated machine. The filtration hollow fiber membrane is an ultra-filtration membrane (UF) with a pore size range of 0.04 μm. Mainly used for the retention of suspensions and organics. Its characteristics can maintain a certain concentration of microorganisms in the biological reaction tank and purify the sewage.

1. Equipment overview

   Due to the existence of the MBR membrane, the solid-liquid separation capability of the system has been greatly improved, so that the effluent, water quality and volume load of the MBR sewage treatment integrated machine have been greatly improved. Standard), after disinfection, it finally forms high-quality reclaimed water with high water quality and biological safety, which can be directly used as a new water source. Due to the filtration effect of the membrane, the microorganisms are completely trapped in the MBR sewage treatment integrated machine, which realizes the complete separation of the hydraulic retention time and the activated sludge sludge age, and eliminates the sludge bulking problem in the traditional activated sludge method. The MBR sewage treatment integrated machine has high removal efficiency of pollutants, strong nitrification capacity, can simultaneously carry out nitrification, denitrification, good denitrification effect, stable effluent quality, low excess sludge output, compact equipment, and small footprint (only traditional 1/3-1/2) of the process, convenient incremental expansion, high degree of automation, and simple operation.

   MBR sewage treatment integrated treatment equipment has the advantages of compact structure, beautiful appearance, small footprint, low operating cost, stability and reliability, high degree of automation, and convenient maintenance and operation. The effluent quality of MBR sewage treatment is better than that of reclaimed water. It is the most advanced sewage treatment equipment in the world today. The series of membrane modules of the MBR sewage treatment integrated machine have formed a standardized series of products, each module is composed of several standard membranes, and can also be individually designed according to the needs of users to meet the needs of users.

2. Process flow

   The core of MBR integrated equipment treatment equipment is based on immersed high-strength hollow fiber membrane separation and biological reaction technology. Secondary settling tank and sand filter system. Its characteristics are that the water quality of the treated water is very good, the suspended solids, COD, NH3-N, BOD5 and turbidity are very low, and it can be directly reused as miscellaneous water, such as domestic miscellaneous water other than drinking water, landscaping, car washing, etc.; industrial water. , such as circulating cooling water or directly as reverse osmosis feed water, production boiler make-up water and ultra pure water for the electronics industry.

3. The advantages

1. High pollutant removal efficiency and good effluent quality;

2. The sludge concentration is high, the volume load of the device is large, and the floor area is small;

3. It is conducive to the retention of slow-proliferating or high-efficiency microorganisms, and improves the nitrification effect of the system and the processing capacity of refractory organic matter;

4. The amount of excess sludge produced is low;

5. Easy to realize automatic control, convenient operation and management;

6. The SS and turbidity of the water discharged after treatment are close to zero, which can be reused.
