With the great increase of the point positions and frequency of water quality monitoring, the traditional manual sampling monitoring analysis can not fully meet the requirements of current environmental management.
2. Continuous on-line monitoring of fixed stations
Since the data volume of manual monitoring is less, China gradually starts to establish surface water automatic monitoring stations on key monitoring sections of surface water from the nineties of the last century. The monitoring indexes of the relatively complete automatic online water quality monitoring station are five parameters (temperature, pH, turbidity, conductivity and DO) and technical indexes such as ammonia nitrogen, total phosphorus, total nitrogen, permanganate index and the like, and the automatic online water quality monitoring station is used for preventing and early warning the water quality of a key section and realizing normalized water quality monitoring, so that the on-line monitoring station realizes the aim of all-weather monitoring for 24 hours and relatively comprehensively understands the change condition of the water quality.
