一、Product Introduction
Haipuou Environmental Protection’s prefabricated wastewater treatment plant is an innovative, modular, intelligent, and low-carbon system that disrupts traditional civil engineering-based construction methods. By abandoning on-site concrete pouring in favor of an industrialized approach—featuring factory prefabrication, on-site assembly, and intelligent O&M—it serves as a mainstream next-generation solution for new municipal wastewater plants, as well as for expansion, upgrading, and emergency treatment projects. The system integrates functional units such as screening pretreatment, biochemical treatment, sedimentation/purification, and sludge handling. These units are standardized via BIM 3D modeling and undergo precision prefabrication, anti-corrosion treatment, and watertightness testing in the factory; module dimensional tolerances are controlled within ±2mm, and a 72-hour full-load water test ensures consistent, controllable quality.
Constructed from high-quality 304/316L stainless steel, the system utilizes structures optimized through CFD fluid dynamics simulation. A corrugated turbulent flow design replaces traditional fixed tanks, significantly enhancing water-air-sludge mixing efficiency and delivering treatment capacity per unit volume that far exceeds traditional processes. Rapid on-site assembly is achieved through high-strength bolted connections and precision hoisting, eliminating the need for complex concrete pouring and curing; the total construction cycle is just 90–120 days, with the main installation for a 10,000-ton-per-day project completed in under 30 days—reducing the timeline by over 70% compared to traditional plants. The equipment supports disassembly, reconfiguration, capacity expansion, and relocation, with a module reuse rate of up to 90%, effectively resolving industry pain points such as rigid structures, difficult modifications, large footprints, construction-related disturbances, and high O&M costs.
The product features a digital twin smart water cloud platform integrating AI control and IoT-based remote O&M systems. It enables real-time monitoring of over 20 water quality and equipment parameters with rapid fault warning responses. Additionally, it incorporates green energy systems—including photovoltaics, wind power, waste heat recovery, and effluent power generation—to ensure intelligent, energy-efficient, and low-carbon operation. The effluent quality consistently meets the Class 1A standard of the *Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants* (GB18918-2002), aligning with national "Dual Carbon" environmental policies.
二、Product Advantages
1. Rapid Construction and Commissioning; Drastically Shortened Timelines
It breaks the mold of the lengthy 1–2 year construction periods typical of traditional wastewater plants. By employing a parallel workflow—where factory prefabrication occurs simultaneously with on-site foundation work—it eliminates the need for concrete curing times; on-site assembly requires only hoisting and joining, reducing the overall construction schedule by 60%–80%. Labor requirements are cut by over 50%, simplifying workforce management and enabling rapid responses to urgent needs such as emergency water remediation or urgent plant upgrades. Commissioning and operational results are achieved far faster than with traditional civil engineering methods.
2. Minimal Footprint; Significantly Enhanced Space Utilization
Leveraging a compact modular structure and design optimized via CFD (Computational Fluid Dynamics) simulation, the system utilizes corrugated turbulent flow structures to intensify mixing and reaction processes. This ensures effective treatment without the need to increase tank volume, boosting wastewater treatment efficiency per unit volume by 30%–50%. The equipment occupies only one-sixth to one-tenth of the footprint of a traditional civil-engineered plant, perfectly solving siting challenges in land-constrained areas like city centers and industrial parks, and making it suitable for projects with limited space.
3. Precision Engineering and Durability; Lower Total Lifecycle Costs
The main structure is fabricated from 304/316L stainless steel, offering superior resistance to corrosion, aging, and wastewater erosion; the equipment boasts a service life of over 30 years without requiring frequent anti-corrosion maintenance. Unlike traditional reinforced concrete structures—which are prone to leakage and damage and often require major overhauls after 10–15 years—this prefabricated modular design offers structural stability and excellent sealing. With minimal ongoing maintenance required, long-term costs associated with inspection, refurbishment, and retrofitting are fundamentally reduced.
4.Eco-friendly Construction:Zero Disturbance and Low Pollution
The process relies primarily on factory prefabrication supplemented by on-site assembly, avoiding the "wet work" typical of traditional civil construction. This significantly reduces noise, dust, and construction waste, minimizing disruption to local residents and the ecosystem. The low-carbon, green construction method is ideal for wastewater plant projects in environmentally sensitive areas, such as urban centers, residential neighborhoods, and scenic spots.
5. Intelligent, Precise O&M with Significant Energy and Resource Savings
Equipped with a digital twin-based smart management system, the facility enables real-time monitoring of over 200 equipment and water quality parameters with one-second dynamic response times. AI algorithms facilitate precise aeration and intelligent chemical dosing. Technologies such as DO (Dissolved Oxygen) fuzzy PID control and machine learning-based water quality prediction dynamically adjust operating parameters, resulting in a 10%–27% reduction in electricity consumption, a 7.5%–30% cut in chemical usage, a 30% reduction in sludge volume, and a 40%–62.5% saving in O&M labor—significantly lowering overall wastewater treatment operating costs.
6. Flexible Adaptability: Scalable, Relocatable, and Reusable
Utilizing standardized "Lego-style" modular interfaces combined with high-strength bolting and elastic sealing technology, the system supports non-destructive disassembly, reconfiguration, capacity expansion, and relocation, achieving a module reuse rate of 90%. Treatment capacity can be flexibly adjusted based on changes in wastewater volume and quality, accommodating phased construction and process upgrades. This effectively resolves the issues associated with traditional plants, such as rigid structures, difficult retrofitting, and high sunk costs.
7. Green Energy Integration: Supporting "Dual Carbon" Goals
The system can be flexibly equipped with on-site photovoltaic storage, small-scale wind power, zero-head effluent power generation, and waste heat recovery systems. These features enable energy self-sufficiency and convert thermal energy from the treatment process into heating energy, comprehensively reducing energy consumption and carbon emissions in alignment with national policies on pollution reduction, decarbonization, and green development.
