Description

technical field [0001] The present application relates to the technical field of environmental monitoring, in particular to a water environment monitoring and management system. Background technique [0002] With the rapid development of sensors and communication technologies, the use of water quality sensors combined with Internet of Things technology to achieve real-time online monitoring of water quality has been widely used in the field of environmental monitoring in recent years. Existing water quality sensors are mostly used to monitor conventional indicators such as Chemical Oxygen Demand (COD), dissolved oxygen, and ammonia nitrogen in water bodies, but cannot detect trace pollutants such as heavy metals and persistent organic compounds in the water environment in real time. monitor. Therefore, the online monitoring system based only on water quality sensors cannot realize the comprehensive monitoring of water pollutants. [0003] Passive sampling technology can me...
