摘　　要：为实现对水体污染源的准确识别,提出基于水质单因子指数的水体污染源识别方法。在确定研究对象后,根据水域的实际情况布设监测点位置。然后选定总氮、总磷、氨氮、高锰酸盐指数、重金属污染浓度以及细菌总数量6项指标用于反映水体的营养物质含量、有机污染程度和水体的氧化还原状态、酸碱度等。根据指标测定结果,利用因子分析方法精准识别水体污染源。然后,在已确定的水污染源附近,定期采集水样和检测指标,监测水质指标在不同阶段的变化情况,以期为水域污染治理提供支持。To achieve accurate identification of water pollution sources,a water pollution source identification method based on water quality single factor index is proposed.After determining the research object,it sets up monitoring points based on the actual situation of the water area.Then,six indicators,including total nitrogen,total phosphorus,ammonia nitrogen,permanganate index,heavy metal pollution concentration,and total bacterial count,are selected to reflect the nutrient content,organic pollution level,redox status,acidity,and alkalinity of the water body.Based on the measurement results of indicators,factor analysis method is used to accurately identify water pollution sources.Water samples and test indicators near the identified water pollution sources are collected to monitor the changes in water quality indicators at different stages,in order to provide support for water pollution control.
