河道型水库富营养化及水华调控方法和关键技术

Key technologies and methods for regulation and control of eutrophication and algal blooms in channel-type reservoirs

本文提出了河道型水库富营养化及水华调控的系统研究方法,重点探讨了水利水电工程影响下的河道型水库富营养化及水华监测、模拟及调控方法及关键技术,包括流域水环境监测评估与水华预警系列技术,大型水库多维、多场耦合富营养化模拟系统,以及改善河道型水库支流库湾水温层化进而抑制水华暴发的调控方法等,以期为抑制河道型水库支流库湾水华暴发、改善水库水质提供参考和依据。

A systematic study method for regulation and control of eutrophication and algal blooms in channel-type reservoirs is proposed herein,and then the methods of monitoring,simulating,regulating and controlling the eutrophication and the algal blooms in channel-type reservoirs under the impacts of water resources and hydropower projects as well as their key technologies are emphatically discussed,which include a series of technologies for water environment monitoring and algal blooms early warning,the simulating system of the multi-dimensional and multi-field coupling eutrophication in large reservoirs as well as the regulation and control method for improving the water temperature stratification at the cove of the branch reservoir of the channel-type reservoir and then restraining the algal blooms,so as to provide a reference and basis for restraining the algal blooms at the cove of the branch reservoir of the channel-type reservoir and improving the water quality of the reservoir concerned.
