Abstract

Less

In order to explore the water quality and pollution characteristics of the main water system in Chengde area, the monitoring data of 29 sections of Chengde surface water quality monitoring station from 2017 to 2020 were selected, and the water environment quality of the main water system in Chengde area was comprehensively evaluated by single factor evaluation, comprehensive pollution index and principal component analysis. The evaluation results show that generally speaking, the overall water quality of the main water system in Chengde is good from 2017 to 2020; From the perspective of time, the water quality of the main water system in Chengde in 2019 and 2020 was significantly improved compared with 2017 and 2018; From the perspective of space, the section pollution of Gonghou and Chenggang bridges is relatively serious. The water quality of the main water system in Chengde is mainly affected by the total phosphorus, COD and permanganate index.
