Containerized integrated sewage treatment equipment is a modular, fully integrated system that packages pretreatment, biochemical reaction, advanced filtration/membrane separation, disinfection and other complete treatment units into standard shipping containers (20ft/40ft).

It is fully prefabricated in the factory. On-site installation only requires ground hardening, water and power connection for rapid commissioning, with no large-scale civil construction needed.

Main structure:

• Grille/regulation tank (pretreatment)
• Anoxic/aerobic tank (A²O/MBR biochemical stage)
• Membrane tank
• Disinfection system (UV/sodium hypochlorite)
• Sludge thickening/dewatering unit
• PLC control cabinet, blower and pump room

1. MBR Process (Preferred for Domestic Sewage)

   Pretreatment + A²O + MBR Membrane Bioreactor + UV disinfection.

   Stable effluent meets Grade I A standard or above, suitable for direct reuse.

   Ideal for villages, towns, scenic spots, hospitals.

2. A/O + Contact Oxidation

   Suitable for small-to-medium domestic sewage, moderate cost, easy operation.

3. DTRO/STRO (High-Difficulty Wastewater)

   For landfill leachate, high-salinity industrial wastewater.

   Achieves high recovery rate and compliant discharge via disc tube reverse osmosis.

4. Advanced Oxidation (UV/H₂O₂/Ozone)

   Treats refractory industrial wastewater (printing & dyeing),

   enhances COD and color removal.

• Small Footprint: Only 1/3–1/2 of traditional sewage plants, stackable.
• Short Construction Period: Factory prefabrication + on-site installation in 1–2 weeks, 70% faster than civil engineering projects.
• High Mobility: Hoistable and transportable, suitable for emergency projects (floods, temporary medical stations), movable after completion.
• Intelligent Operation: PLC automatic control + remote monitoring, supports unattended operation and reduces labor cost.
• Stable Effluent Quality: MBR effluent: SS<5mg/L, NH₃-N<1mg/L, meets Grade I A, Surface Water Class IV or reuse standards.
• Low Civil Cost: Above-ground installation, only concrete hardening required, no excavation or anti-seepage tank needed.

• Distributed domestic sewage: villages, towns, scenic areas, service areas, islands.
• Industrial wastewater: food processing, electronics,printing & dyeing.
• Emergency treatment: post-disaster temporary sewage treatment, municipal pipeline repair, temporary construction sites.
• Upgrading & retrofitting: existing sewage plants with MBR or advanced oxidation modules.

• Capacity: Single unit 50–1000 m³/d; multiple units in parallel up to 10,000 m³/d+.
• Material: Q235 carbon steel with anti-corrosion coating (service life 20–30 years), stainless steel (for highly corrosive wastewater).
• Operating Conditions: Temperature 5–40°C, pH 6–9.
• Selection Basis: Influent quality (COD, BOD, SS, NH₃-N, TP, salinity), flow fluctuation, effluent standard, site constraints, budget.

The containerized integrated equipment from Shandong Zhongqiao Qidi Environmental Protection Equipment Co., Ltd. adopts MBR + UV disinfection process. Shipped from the Weicheng production base in Weifang, it quickly serves village and industrial projects in North and East China.

Effluent stably meets Discharge Standard of Pollutants for Urban Sewage Treatment Plants (GB18918-2002) Grade I A.

Notes:

• Regular MBR membrane cleaning to prevent fouling.
• Winter insulation for northern regions (heating or insulation layer optional).
• Complete sludge disposal plan (authorized transportation or built-in dewatering machine).

• Price Range: For a 200 m³/d MBR container unit, generally several hundred thousand RMB, depending on material, membrane brand and configuration.
• Operation Cost: Power consumption (0.3–0.5 kWh/m³) + chemicals + membrane replacement (MBR membrane service life 3–5 years).
• Discharge Standard: Confirm local environmental protection requirements to avoid non-compliance due to improper process selection.
