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.

• 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

• 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

• 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.

• 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)

• Laser cutting and shearing machine blanking ensure high dimensional accuracy, less burr, easier assembly and welding.
• In-house large bending machine for structural parts, assembly line production.
• Pipe processing by pipe bender and threading machine, reducing welding, lower failure rate and better appearance.
• Assembly line operation ensures short construction period and fast commissioning.
• High-standard accessories and first-line brand electrical and mechanical equipment ensure stable operation.
• Scientific water distribution design greatly improves tank utilization.
• 55–60° sludge hopper design, no sludge accumulation.
• Reasonable pipeline layout reduces head loss.
• 12 years of production experience plus professional structural design team ensure firm and reliable structure under all working conditions.
• Professional process engineers capable of independent design and optimization; we fully understand drawings and can integrate design concepts into production, giving the equipment “soul".
