ZhongqiaoBox Integrated Sewage Treatment Equipment
ZhongqiaoBox integrated sewage treatment equipment is mainly applied in rural sewage, hospitals, small and medium-sized emergency sewage treatment plants, and other scenarios. It is a skid-mounted device composed of a box body, supporting electromechanical equipment, pipelines and accessories, and a control system.
The mainstream processes include AO and AO+MBR. According to different application scenarios, it can be classified into:

• Flat-plate type
• Container type
• Submersible type
• Decorative plate type

The main material is carbon steel; it can also be made of PP, stainless steel, FRP, and other special materials.
ZhongqiaoBox was originally designed for OEM production. It is a non-standard product with customizable process, material and appearance, featuring practicality, stability, economy and customer privacy.
ZhongqiaoBox aims to provide dual value to intermediaries/engineering contractors and end users. “ZhongqiaoBox” is only a temporary name; it may be replaced with the customer’s brand name upon delivery to create value.

ZhongqiaoBox integrated sewage treatment equipment covers a treatment capacity of 5–5,000 tons per day, and can be flexibly adapted to different scenarios through single unit, parallel connection of multiple units, or modular expansion.

1. Standard Treatment Capacity (Single Unit / Basic Module)

• Small scale (5–50 tons/day): Rural sewage, small hospitals, homestays, emergency sites
• Medium scale (50–500 tons/day): Residential quarters, towns, small and medium-sized factories, scenic spots
• Large scale (500–5,000 tons/day): Industrial parks, centralized treatment, large emergency projects

2. Expansion Capacity (Modular Combination)

• Adopts expandable container / skid mounted modules, with a single unit of 10–100 tons/day.
• Multiple units in parallel can achieve flexible expansion to 20–500 tons/day.
• Project examples:
  • Saudi Arabia project: 4 units in parallel = 1,200 tons/day
  • Tianjin / Xinjiang projects: up to 2,000 tons/day

3. Treatment Efficiency & Process

• Main processes: AO, AO+MBR, stably removing COD, ammonia nitrogen, total nitrogen, total phosphorus.
• Effluent standards: Level 1A / Level 1B, reclaimed water reuse, local discharge standards.
• Strong shock resistance: adapts to water quality fluctuations, low sludge yield, stable operation.

4. Selection by Scenario

• Rural areas / small hospitals: 5–50 tons/day
• Residential quarters / towns: 50–200 tons/day
• Industrial parks / large emergency: 500–2,000 tons/day
• Ultra-large scale: 2,000–5,000 tons/day (multi-module combination)
