    Control Index for Water Regulation in Fish Breeding Season for Dongta Spawning Ground after Operation of Datengxia Gorge Water Conservancy Project by LIU Lishi, WANG Li, GE Xiaoxia, TAN Xichang

    Published 2022-01-01
    “…After the operation of the Datengxia Gorge water conservancy project,the change in the hydrological rhythm of the downstream river channel may have a certain impact on the function of the Dongta spawning ground about 10 km downstream.To maintain the normal function of the Dongta spawning ground,we should analyze the hydrological rhythm process required for fish spawning and use it as a control index to implement ecological regulation of reservoirs and thus restore the ecological environment of river channels.According to the observation data of early fish resources and hydrology over the past dozen years,the correlation between early fish resources and hydrological characteristic values in the Dongta spawning ground is analyzed by different statistical methods such as grey relational analysis and linear regression.In combination with the practical experience of ecological regulation in the Xijiang River Basin,the control index requirements for water regulation during the fish breeding period by the Datengxia Gorge water conservancy project are put forward.Specifically,by the regulation of the Datengxia Gorge water conservancy project from May to July every year,when the section flow rate of Dahuangjiangkou exceeds 3 500 m<sup>3</sup>/s,the water rise duration shall be no less than four days,with the daily rise rate in the water rise stage of more than 1 000 m<sup>3</sup>/s.The time for water to recede shall be no less than three days,and the flow rate in the water recession stage shall be above 3 500 m<sup>3</sup>/s.The regulation shall be performed at least once each year.The research results can provide a technical reference for maximizing the function of the Dongta spawning ground in the fish breeding period by the regulation of the Datengxia Gorge water conservancy project.…”

    Discussion on the Application of Water Environment Treatment and Three-water Separation Project in Shenzhen by TANG Yawen, CHEN Wangwang

    Published 2022-01-01
    “…To fulfill the overall requirement of long-term cleanliness and sustainable development of the water environment in Shenzhen,this paper investigates the Longgang River Basin Water Environment Management Project to propose a general three-water separation plan that integrates “closed sewage system,open rainwater system,and efficient interception system”.Tracing to the source and diversion of key outlets and sewage interception transformation are carried out to release the clean base flow,drive the sewage system to be relatively independent from the initial light rain system,and ultimately to slow down non-point source pollution,improve the quality and efficiency of the sewage treatment plant,and strengthen the operation and maintenance scheduling of the pipe network system.With the implementation of the three-water separation project,the influent biochemical oxygen demand (BOD) concentration of the sewage treatment plant in the Longgang River Basin is significantly lower than that in 2019 after the second half of 2020.Therefore,applying the three-water separation project to water environment treatment is essential for fulfilling the assessment requirements on water control and quality improvement in Shenzhen and accomplishing relevant construction tasks.…”
