Product Details

The MBR sewage treatment device is mainly used for treating domestic sewage and industrial organic wastewater.
The integrated Membrane Bioreactor (MBR) sewage treatment plant is designed to treat domestic sewage to achieve the effluent quality of "Grade A+" treatment, making it suitable for reuse in "high-risk category" applications or discharge into sensitive environments.
MBR, also known as the Membrane Bioreactor, is a new type of water treatment technology that combines the activated sludge method with membrane separation technology. The standard treatment process includes influent screening, mixing in the equalization tank, anoxic and aerobic treatment, Ultrafiltration (UF) with an automatic chemical cleaning system, effluent sterilization through ultraviolet light and/or tank recirculation and residual hypochlorite dosing, as well as analyzers for online monitoring of the turbidity, free chlorine, and pH value of the treated effluent. Additional treatment steps for nutrient removal (TN and TP) and a sludge dewatering system can be added as required to meet the influent water quality and/or treated effluent water quality requirements.
The bioreactor is made of corrosion-resistant glass fiber reinforced plastic and is an independent modular system that can be easily deployed to remote areas.

Features

Compared with many traditional biological water treatment processes, the MBR mainly has the following characteristics:
(1) High and stable effluent water quality. Due to the efficient separation effect of the membrane, the separation effect is far better than that of traditional sedimentation tanks. The treated water is extremely clear, with suspended solids and turbidity close to zero, and a large number of bacteria and viruses are removed. The treated water quality is better than the quality standard for domestic miscellaneous water (CJ25.1-89) promulgated by the Ministry of Construction, and it can be directly reused as non-potable municipal miscellaneous water. At the same time, membrane separation also enables the complete retention of microorganisms in the bioreactor, maintaining a high concentration of microorganisms in the system. This not only improves the overall removal efficiency of the reaction device for pollutants but also ensures good effluent water quality. At the same time, the reactor has good adaptability to various changes in the influent load (water quality and quantity), can withstand shock loads, and can stably obtain high-quality effluent water.
(2) Less excess sludge production. This process can operate under high volume load and low sludge load, with less excess sludge production (theoretically, zero sludge discharge can be achieved), reducing the cost of sludge treatment.
(3) Small footprint and not limited by the installation location. The bioreactor can maintain a high concentration of microorganisms, with a high volume load of the treatment unit, which is economical in terms of land occupation. The process flow is simple and compact, with a small footprint, not limited by the location, and suitable for any occasion. It can be made into above-ground, semi-underground, or underground types.
(4) Can remove ammonia nitrogen and refractory organic compounds. Microorganisms are completely retained in the bioreactor, which is beneficial for the retention and growth of slow-growing microorganisms such as nitrifying bacteria, and can improve the nitrification efficiency of the system. At the same time, it can increase the hydraulic retention time of some refractory organic compounds in the system, which is beneficial for improving the degradation efficiency of refractory organic compounds.
(5) Convenient operation and management, and easy to achieve automatic control. This process realizes the complete separation of the hydraulic retention time (HRT) and the sludge retention time (SRT), and the operation control is more flexible and stable. It is a new technology that is easy to be integrated in sewage treatment, and it can achieve microcomputer automatic control, making the operation management more convenient.
(6) Easy to transform with traditional processes. This process can be used as a deep treatment unit of the traditional sewage treatment process, and has broad application prospects in the field of deep treatment of the effluent from secondary sewage treatment plants in cities and towns (thus realizing a large amount of reuse of urban sewage).
