Study on Water Quality in Suining Section of Qijiang River Based on Unmanned Surface Vehicle Technology
摘要
Abstract
In order to study the water environment quality in Suining section of Qijiang River,the navigation monitoring of the main stream and eight tributaries of the Qijiang River was carried out using the automatic cruise unmanned surface vehicle.Nemerow comprehensive index and section category ratio method was used to comprehensively analyze the water quality.At the same,a field investigation was conducted on the discharge outlet of the river,and some important discharge outlets were selected to carry out navigation monitoring and evaluate the impact on the water environment quality.The results showed that the navigation technology of unmanned surface vehicle has high precision and efficiency,can complete the water quality investigation.The water quality of Qijiang River is light pollution.The primary pollutant is chemical oxygen demand(CODCr).The water quality of the tributaries are poor,which have a direct impact on the water body of the main stream.The water flow of rainwater outlets is small,so they have low total pollutant emission,therefore they have little impact on water quality of Qijiang River.The primary pollutant of most discharge outlets is CODCr,which increases the organic load of water body.The research can provide theoretical basis for medium-and long-term water quality improvement decision support,and promote the continuous improvement of water quality in the basin.关键词
