Product Features

Containerized Decentralized Sewage Treatment Equipment (AO+MBR Technology) 5

Rapid Deployment & Plug-and-Play

All components are pre-installed in standard containers, requiring only a solid foundation for placement. It can be put into operation immediately after connecting water and electricity, greatly shortening the construction cycle.

Compact Footprint

The integrated design saves 60% of the area compared with traditional sewage treatment plants, suitable for areas with limited space.

Intelligent Operation & Maintenance

Equipped with IoT monitoring module and intelligent control system, realizing automatic operation, remote monitoring, fault alarm, and diagnosis. It can achieve unattended operation, reducing labor costs.

Durable & Corrosion-Resistant

The container body adopts anti-corrosion materials, and core components (such as aeration discs, MBR modules) are from international well-known brands, ensuring stable operation in harsh environments (high temperature, humidity, etc.).

Modular Expansion

Multiple containers can be connected in parallel to meet the needs of different treatment scales (from 30m³/d to 1000m³/d), suitable for both small-scale villages and large-scale resorts.

Energy-Saving & Low Operating Cost

Adopts high-efficiency submersible blowers and energy-saving pumps, with low power consumption. The simple maintenance process further reduces the overall operating cost.

Core Technology: AO + MBR Integration

The synergy of AO process and MBR technology achieves efficient removal of pollutants while ensuring superior effluent quality, making it a leading solution in decentralized sewage treatment.

AO (Anaerobic-Oxic) Process

Anaerobic Stage

Anaerobic bacteria decompose macromolecular organic substances (such as proteins and polysaccharides) into small-molecule organics (organic acids, alcohols, etc.), reducing the load for subsequent treatment. Polyphosphate-accumulating organisms (PAOs) release phosphorus, laying the foundation for phosphorus removal.

Oxic Stage

Aerobic microorganisms oxidize and decompose organic substances into carbon dioxide and water. Nitrifying bacteria convert ammonia nitrogen (NH₃-N) into nitrates (NO₃⁻) through nitrification, while PAOs absorb phosphorus in excess, realizing effective nitrogen and phosphorus removal.

Technology Advantages

Superior Effluent Quality

The effluent is clear and transparent, meeting the first-class A standard of GB18918-2002 (Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants) or relevant international standards, and can be reused for irrigation, landscape, and other purposes.

High Pollutant Removal Rate

COD, BOD₅, SS, NH₃-N, TN, and TP removal rates reach over 90%, 95%, 99%, 90%, 85%, and 85% respectively.

Low Sludge Production

Operates under high volume load and low sludge load, significantly reducing residual sludge output and sludge disposal costs.

Note: The above parameters are based on conventional design using surface water as the raw water source. For special raw water (e.g., high fluoride, high arsenic, brackish water, etc.), additional processes (such as RO Reverse Osmosis, Ion Exchange, etc.) will be equipped. The finished water quality can meet the "Standards for Drinking Water Quality" (GB 5749-2022) or even higher standards.

MBR (Membrane Bio-Reactor) Technology

Containerized Decentralized Sewage Treatment Equipment (AO+MBR Technology) 18

High-Efficiency Solid-Liquid Separation

MBR membranes with pore sizes ranging from 0.01 to 0.4μm act as a precise "sieve", effectively retaining activated sludge, microorganisms, colloids, and suspended solids. Only water and small-molecule substances can pass through, ensuring effluent turbidity is close to zero.

Stable Effluent Quality

Compared with traditional sedimentation tanks, MBR technology achieves more reliable sludge-water separation, eliminating the risk of sludge bulking. The extended sludge retention time (SRT) facilitates the decomposition of refractory organics by slow-growing microorganisms, further improving treatment efficiency.
