Project Background
Customer Background Introduction:
Hunan Agricultural University is a teaching and research university that focuses on agriculture and promotes interdisciplinary development. It has multiple colleges including agriculture, horticulture, aquaculture, plant protection, environment and ecology. The campus has built a group of experimental buildings, with an expected daily production of 100 tons of laboratory wastewater. The laboratory wastewater of
presents the following characteristics and challenges:
1. Wastewater characteristics:
• Complex composition: containing acidic, alkaline, organic solvents (such as methanol, benzene derivatives), heavy metals (such as lead, chromium, cadmium, mercury), microbial cultures, etc. The water quality and quantity fluctuate greatly.
• Toxicity and hazard: Some wastewater is corrosive and toxic, and cannot be directly discharged into municipal pipelines.
• Strict emission standards: It is necessary to meet both the "Water Quality Standards for Sewage Discharged into Urban Sewers" (GB/T 31962) and the stricter emission limits set by local environmental protection departments.
2. Core challenge:
• Difficulty in classification and collection: Hundreds of laboratories generate a wide variety of types of wastewater, and source classification and collection management are huge challenges.
• Difficulty in integrating treatment technologies: There is no universal technology that can treat all pollutants, requiring an integrated and intelligent combination process.
• Safety and compliance risks: The system must be safe and reliable, prevent accidents such as leaks, poisoning, and explosions, and pass the "three simultaneous" environmental protection acceptance.
