    Application of Load Duration Curve Method in Pollution Control in the Middle and Lower Reaches of Hanjiang River by ZHAO Chen, CHEN Yanfei, DONG Yuru, SUN Yongxi

    Published 2022-01-01
    “…The load duration curve method is used to study both water quality change and pollution load.This study aims to examine the effect of pollution control in the middle and lower reaches of the Hanjiang River and puts forward reasonable pollution control measures.For this purpose,the load duration curves of total phosphorus,COD<sub>Mn</sub>,and ammonia nitrogen are drawn according to the hydrological data and water quality data for 2006—2020,with water pollution prevention and control and the local water quality requirements as the design water quality objectives.The relationships among water flow,water quality,and pollution load are thereby established.The results show that under the corresponding specified surface water quality,the COD<sub>Mn</sub>,ammonia nitrogen,and total phosphorus indexes of the Huangzhuang section all meet the requirements,and the residual load is large,which means that no reduction measures are needed.Regarding the Xiantao section,reduction measures are also unnecessary for COD<sub>Mn</sub> and ammonia nitrogen,which,nevertheless,is not the case for the high and low flow areas of total phosphorus.The reduction amounts for the two areas are 6.05 t/d and 0.09 t/d,respectively.This study provides technical support for water quality compliance management under different hydrological conditions of the river.…”

    Water Environment Pollution and Its Countermeasuresin Hanjiang River Ecologic Economic Belt by ZHANG Zhongwang, CHEN Yao, XU Cungang

    Published 2020-01-01
    “…The results show that: (1) In general, the water quality of the mainstream of the Hanjiang River is good, but it develops in the wrong direction. (2) The water quality of tributary tends to be better, but the pollution in some tributaries is still serious. (3) The water quality of the main stream and tributary in the Danjiangkou reservoir area is stable, but the water pollution during the dry season is more serious. (4) The water blooms in the lower reaches of the Hanjiang River occurs more and more frequent. …”
