Application Scenarios
The ANJ-MBBR system is primarily designed for rural domestic wastewater treatment, low-temperature turbid water management, and black-odor water body remediation. It serves both new construction projects and equipment upgrades/standardization initiatives. Key applications include: wastewater treatment in villages, towns, residential complexes, office buildings, and commercial facilities; urban sewage systems; public infrastructure such as hospitals and schools; and industrial wastewater processing for small-to-medium enterprises like slaughterhouses, aquatic product processing plants, and food manufacturers.

Product Composition
The ANJ-MBBR system mainly adopts the A/A2O process, consisting of a pre-anoxic tank, anaerobic tank, anoxic tank, oxic tank, sedimentation tank, and equipment room. The oxic tank is equipped with MBBR (Multi-membrane Blanket Reactor) media, while the sedimentation tank utilizes inclined tube or vertical flow sedimentation tanks. The re-circulation system predominantly adopts an energy-efficient air-lift return mechanism. The equipment room integrates UV disinfection units and control systems alongside standard components like fans and pumps.

Process Principle

Process Flow
The typical process flow of ANJ-MBBR products is as follows: After intercepting large suspended solids and debris through a bar screen, wastewater enters the equalization tank for homogenization and volume adjustment. The water is then pumped to the pre-anoxic tank where it mixes with returned sludge. In this stage, nitrate and oxygen in the returned sludge are thoroughly removed, ensuring strict anaerobic conditions in the anaerobic tank. This significantly enhances the phosphorus release efficiency of phosphate accumulating bacteria within the anaerobic system.
The wastewater then enters the anaerobic tank, where phosphorus-reducing bacteria release phosphorus in a strictly anaerobic environment, preparing for subsequent aerobic phosphorus uptake. It subsequently flows into the anoxic tank, where mixed liquor recirculated from the secondary sedimentation tank contains nitrate-rich sewage. This stream can fully utilize the high-quality carbon source in the influent to achieve denitrification and nitrogen removal.
The effluent from the anoxic tank enters the MBBR aerobic tank. Under the application of high efficiency aeration and anti-filler accumulation technology, the sewage in the aerobic tank is fully contacted and mixed with the MBBR filler to effectively decompose organic matter; the phosphate accumulating bacteria absorb phosphorus in excess and realize the removal of total phosphorus through the discharge of surplus sludge.
Wastewater treated in the MBBR aerobic tank enters the secondary sedimentation tank to separate suspended sludge and impurities. The separated supernatant is channeled into the disinfection system, where harmful pathogens are eliminated before meeting discharge standards. A portion of the mixed liquor from the middle-lower section returns to the front end via recirculation, while the remaining liquid settles in the sludge hopper as excess sludge, which is then transferred to the sludge storage tank for regular external disposal.
Product Core Technology and Characteristics
Core Technical Advantages
Sludge Film Coupling Method
The core technology of ANJ-MBBR (Anaerobic Nitrification-Marine Biofilm Reactor) adopts a sludge film coupling method, where the reaction system simultaneously contains activated sludge and biofilm. This dual-process approach leverages their respective strengths while mitigating weaknesses, resulting in enhanced resistance to shock loads. Compared to traditional activated sludge process (ASP), MBBR demonstrates higher biomass production and more stable treatment performance, particularly showing greater robustness when handling water quality fluctuations.
Anti-filler Accumulation Technology
The ANJ-MBBR product utilizes proprietary anti-clogging technology (Patent: Utility Model Patent granted, an integrated sewage treatment system with anti-clogging design, ZL2022203233982). Through zoned aeration system deployment and suspended fabricated packing nets, the equipment prevents sludge accumulation. The intermittent agitation of sludge in dead zones eliminates buildup, thereby enhancing sludge loading capacity and improving wastewater treatment efficiency.
This technology not only reduces the number of failure points, but also reduces equipment investment and operation and maintenance energy consumption. By adopting the anti-fill accumulation technology, the mixing equipment inside the equipment is eliminated, which not only reduces the number of failure points, but also reduces equipment investment and operation and maintenance energy consumption.
Vortex Self-Stirring Technology
The ANJ-MBBR product achieves self-stirring of water flow within the tank through the installation of a vortex guide cylinder and hydrocyclone water distribution system (patented technology: authorized invention patent, a self-stirring wastewater treatment device and control method based on hydraulic vortex theory, ZL202311835457X). This significantly reduces energy consumption compared to traditional wastewater treatment processes while enhancing dissolved oxygen transfer efficiency and ensuring more stable treatment performance.
Compared with the traditional system that needs mechanical or gas stirring, the vortex self-stirring technology can realize the self-stirring of water flow in the tank, improve the dissolved oxygen mass transfer effect, and significantly lower the energy consumption than the traditional sewage treatment process, and the treatment effect is more stable.
Intelligent Control System
The ANJ-MBBR product, built on automated operation, utilizes big data analysis and control logic programming to activate energy-saving mode under low-load conditions (with proprietary intellectual property: Xinyu Technology's Intelligent Supervision System for Rural Wastewater Treatment, Version 1.0, 2022SR0349958). This system not only meets effluent discharge standards but also maximizes cost savings for equipment operation.
This intelligent control system can automatically adjust operation parameters according to water inflow load and water quality, optimize energy consumption, improve processing efficiency and reduce operation and maintenance costs.
Intelligent Operation And Maintenance Platform
The ANJ-MBBR product, integrated with our self-developed intelligent operation and maintenance platform (with proprietary intellectual property: Digital Intelligent Management Application Platform for Wastewater Treatment Plants V1.0, 2023SR1352648), enables true unmanned operation. This innovation addresses the persistent challenges in rural wastewater treatment facilities, including operational difficulties, high costs, frequent malfunctions, inadequate maintenance, and delayed repairs.
The Intelligent Operation And Maintenance Platform Has The Following Functions:
1) Monitor the operating status and water quality parameters in real time
2) Automatic warning and fault diagnosis
