- Abstract:
- The continuous development of social economy and city has created serious pollution to urban rivers, which seriously affects the resident’s living and the natural ecological environment. Water quality monitoring is a basic and necessary work in comprehensive management and treatment of urban rivers. The traditional monitoring method is manual sampling monitoring, which often has the disadvantages of low efficiency and heavy workload. Therefore, on-line monitoring and sampling of rivers in Zhangpu Town, Kunshan was carried out by an unmanned surface vehicle with water quality sensors of dissolved oxygen (DO), pH, conductivity, temperature, chemical oxygen demand (COD) and ammonia nitrogen (NH3-N). The water quality status and main pollution factors of urban rivers were analyzed by comprehensive water quality mark indices. The unmanned surface vehicle could automatically avoid obstacles, accurately locate monitoring samples and send back the real-time data according to the pre-planned navigation path under harsh environment, thus realize intelligent water quality monitoring. The monitoring data of COD and NH3-N probes carried by the unmanned surface vehicle were in good consistency with those obtained by laboratory analysis, indicating that the unmanned surface vehicle had a broad application prospect in urban river water quality monitoring.
