Service areas along expressways Wastewater Treatment Equipment
Service Areas Along Expressways Wastewater Treatment Equipment, simply put, is a specialized, efficient, and self-contained sewage treatment system designed for service areas. It effectively treats domestic sewage, catering wastewater, and other effluents to ensure compliant discharge or reuse.
I. Equipment Composition and Process
Core Process: Typically employs a combined “pretreatment + biological treatment + disinfection” approach, such as “screening + septic tank + equalization tank + anoxic tank + aerobic tank + MBR membrane + disinfection.” This reliably removes pollutants like organic matter and ammonia nitrogen, achieving Class 1A discharge standards.
Technical Features: Modular equipment design with high shock load resistance, featuring automatic backwashing and energy-efficient aeration systems for smarter, more power-saving operation.
II. Application Scenarios and Advantages
Applicable Scenarios: Suitable not only for service areas but also for decentralized wastewater sources like toll stations and gas stations.
Core Advantages: Compact footprint, cost-effective investment, high treatment efficiency, and reusable treated water for applications like toilet flushing and landscaping, delivering both environmental benefits and water conservation.
III. Current Challenges and Trends
Primary Issues: Significant fluctuations in passenger volume complicate equipment selection, demanding rigorous operational management. Removing nitrogen, phosphorus, and heavy metals remains challenging.
Future Direction: Greater emphasis on energy conservation, intelligent management, and advancing reclaimed water reuse technologies to meet evolving environmental regulations.
