扬水曝气装置对李家河水库水质指标的影响

Influence of water pumping and aeration device on water quality indicators of Lijiahe Reservoir

本文对李家河水库引水塔处定点、定期采集和测试得到的影响水质的九个重要指标(即溶解氧、电导率、浊度、高锰酸钾指数、总有机碳含量、总氮、总磷、总铁和总锰等)进行分析研究,得到了扬水曝气装置开启前后水体水样在自然混合分层期、非汛期以及汛期各时间段各指标的实际变化规律,研究结论可为水库的正常运行和监管提供有益帮助。

In this paper,nine important indicators affecting water quality obtained from fixed-point and regular collection and testing at the diversion tower of Lijiahe Reservoir are analyzed and studied,which are dissolved oxygen,electrical conductivity,turbidity,potassium permanganate index,total organic carbon content,total nitrogen,total phosphorus,total iron and total manganese,etc.The actual change rules of the water body in the natural mixing stratification period,nonflood season and flood season before and after the opening of the water pumping and gas explosion device are obtained.These works provided help for the normal operation and supervision of reservoir production.
