汕头市Technical Analysis on the Principle, Model Selection and Development Trend of Integrated Sewage Treatment Processor

Core working principle: The synergistic effect of physical interception (bar screens, grit chambers), biodegradation (A²/O, MBR, SBR and other processes), and advanced purification (coagulation sedimentation, disinfection) efficiently removes organic matter, pathogens, heavy metals and other pollutants in sewage, while achieving sludge reduction and water resource recovery.

Classification of mainstream processes: Biological treatment units are suitable for conventional sewage with a nitrogen removal efficiency above 85%; membrane-based treatment (MBR) provides high-precision filtration with a pore size of 0.03-0.4μm for superior effluent quality; ecological treatment (constructed wetlands) applies to low-concentration sewage with lower costs and eco-friendliness.

Innovation in structural materials: The main body adopts 316L stainless steel or FRP with strong acid and alkali resistance and a service life of more than 15 years. PVDF membrane components feature excellent oxidation resistance with a filament breakage rate below 0.01%. Paired with porous suspended fillers having a specific surface area ≥500m²/m³, they improve bacterial adhesion and purification efficiency.

Key technical features: Intelligent management and energy efficiency optimization

Intelligent monitoring and control: Online sensors for pH, DO, ammonia nitrogen and turbidity offer an accuracy of ±0.1% FS. The BP neural network algorithm predicts water quality, and fuzzy PID control cuts aeration energy consumption by 20%-30% with a dynamic response time within 5 minutes.

Energy efficiency optimization: Microporous aerators achieve an oxygen transfer efficiency ≥25% with an optimized air-water ratio of 4:1. The Anammox process reduces nitrogen removal energy consumption by 60%. Some projects integrate photovoltaic power to reach a self-power supply rate of 40%.

Operation cost control: The combined air-water backwashing and chemical cleaning solution delivers a membrane pollution recovery rate above 95%. Redundant configuration of key equipment and dual-circuit power supply ensure continuous operation with MTBF exceeding 100,000 hours.
