💧 Underground Integrated Sewage Treatment Equipment
TheUnderground Integrated Sewage Treatment Equipment is a revolutionary wastewater treatment process that seamlessly combines high-efficiency membrane separation technology with the traditional activated sludge method. By utilizing high-performance microfiltration/ultrafiltration membrane modules, it completely replaces the secondary sedimentation tank and sand filtration units found in conventional processes. It achieves highly efficient solid-liquid separation by directly retaining activated sludge and macromolecular organic matter within the biochemical reaction tank.
Underground Integrated Sewage Treatment EquipmentCore Working Principle & Process:
After pretreatment, the sewage enters the biological reaction tank, where aerobic microorganisms degrade organic pollutants and perform nitrification and denitrification. Subsequently, under negative pressure suction, the mixed liquor permeates through the membrane modules. The resulting effluent is crystal clear and ready for direct reuse, while activated sludge, bacteria, viruses, and suspended solids are completely retained within the tank. This maintains an extremely high microbial concentration (MLSS can reach 8000-12000mg/L), significantly boosting the efficiency of the biochemical reaction.
Why Choose Our MBR System?
1、Superior Effluent Quality Meeting the Strictest Reuse Standards
Thanks to the physical sieving action of the membrane pores (0.01~0.4μm), the effluent turbidity is lower than 0.2 NTU, Suspended Solids (SS) are near zero, and the removal rate of bacteria and viruses exceeds 99.99%. The treated water consistently surpasses national Class A discharge standards and can even meet Surface Water Class IV standards. It can be directly reused for landscaping, flushing, or industrial cooling without requiring further deep filtration.
2、Minimal Footprint, Significantly Reducing Civil Engineering Costs
Because the biological reactor maintains a high concentration of activated sludge, its volumetric load is 2-4 times that of traditional processes, greatly shortening the Hydraulic Retention Time (HRT). Additionally, by eliminating the need for secondary sedimentation tanks and filtration workshops, the overall footprint is reduced by 40%-60%. This makes it perfect for new municipal plants in land-scarce urban areas or for upgrading existing facilities.
3、Highly Automated Operation with Strong Resistance to Shock Loads
The system utilizes intelligent PLC control, achieving a complete separation of Hydraulic Retention Time (HRT) and Sludge Retention Time (SRT), which allows for extremely flexible and stable operation management. Whether facing drastic fluctuations in influent quality and quantity or dealing with high-concentration organic wastewater, the MBR system demonstrates exceptional resilience, ensuring consistent effluent quality./
4、Low Excess Sludge Production for Hassle-Free Maintenance
Under conditions of high sludge age, microorganisms enter an endogenous respiration phase, resulting in extremely low excess sludge discharge (theoretically allowing for zero sludge discharge). This significantly reduces subsequent sludge treatment costs and environmental disposal pressures.
Mainstream Membrane Module Options & Applications:
We offer various forms of MBR membrane modules tailored to different water quality scenarios:
1、Hollow Fiber Membranes: Feature extremely high packing density and relatively low energy consumption, widely used in municipal sewage and large-scale park reclaimed water projects./
2、Flat Sheet Membranes: Possess exceptional anti-fouling properties and stable flux. They are easy to physically clean, making them particularly suitable for treating high-concentration organic wastewater (such as pharmaceutical, chemical, and landfill leachate).
3、Tubular Membranes: Designed specifically for extreme and harsh water qualities, they are resistant to high viscosity and high solid content, commonly used in the pretreatment of specialized industrial wastewater.
If you are looking for a highly efficient solution that not only ensures full environmental compliance but also achieves sustainable water resource recycling, our MBR Membrane Bioreactor will be your most valuable investment.
