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

The entire system is prefabricated in the factory. On-site commissioning only requires ground hardening and connection of water and electricity, with no large-scale civil engineering work needed.

Main structure:

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

• MBR Process (Recommended for Domestic Sewage)

  Pretreatment + A²O + MBR Membrane Bioreactor + UV disinfection.

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

  Ideal for villages, towns, scenic areas, hospitals and similar sites.

• A/O + Contact Oxidation

  Suitable for small-to-medium domestic sewage. Cost-effective and easy to operate.

• DTRO/STRO (High-Difficulty Wastewater)

  Designed for landfill leachate and high-salinity industrial wastewater.

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

• Advanced Oxidation (UV/H₂O₂/Ozone)

  Treats refractory industrial wastewater (printing & dyeing, pharmaceuticals),

  significantly improving COD and color removal efficiency.

• Small Footprint: Only 1/3–1/2 the area of traditional sewage treatment plants; stackable.
• Short Construction Period: Factory prefabrication plus 1–2 weeks on-site installation, 70% faster than conventional civil engineering projects.
• High Mobility: Hoistable and transportable, ideal for emergency projects such as flood relief and temporary medical stations; reusable after project completion.
• Intelligent Operation: PLC automatic control with remote monitoring, enabling unattended operation and lower labor costs.
• Stable Effluent Quality: MBR effluent: SS<5mg/L, NH₃-N<1mg/L, meeting Grade I A, Surface Water Class IV or reuse standards.
• Low Civil Cost: Above-ground installation only requires concrete hardening, no excavation or anti-seepage tank construction.

• Distributed domestic sewage: villages, towns, scenic spots, service areas, islands.
• Industrial wastewater: food processing, electronics, pharmaceuticals, printing & dyeing.
• Emergency treatment: temporary post-disaster sewage treatment, municipal pipeline maintenance, temporary construction sites.
• Upgrading & retrofitting: upgrading 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 and above.
• Material: Q235 carbon steel with anti-corrosion coating (service life: 20–30 years); stainless steel available for highly corrosive wastewater.
• Operating Conditions: Temperature 5–40°C, pH 6–9.
• Selection Basis: Influent characteristics (COD, BOD, SS, NH₃-N, TP, salinity), flow fluctuation, required discharge standard, site conditions, budget.

Containerized integrated wastewater treatment equipment from Shandong Zhongqiao Qidi Environmental Protection Equipment Co., Ltd. adopts the MBR + UV disinfection process. Shipped from the Weicheng production base in Weifang, it provides fast and reliable service for rural and industrial wastewater projects across North and East China.

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