南京市外秦淮河水质模拟及引调水效果
Water quality simulation and water diversion effect analysis of external Qinhuai River in Nanjing
摘要
Abstract
In order to study the influences of water diversion from the external Qinhuai River in Nanjing on the water quality of the Qinhuai River and to evaluate the effect of water diversion, a one-dimensional hydrodynamic and water quality river network model was developed. This model was used to simulate the water quality in the external Qinhuai River during different periods by different means of water diversion from multiple water sources, which include the Yangtze River and Shijiu Lake, and the variation of water quality using different brake control systems. The results show that, in different water diversion schemes, the water quality in the external Qinhuai River can be improved distinctly so long as enough water from the two water sources can be transferred into the external Qinhuai River, and the water quality in parts of the river can even be improved by one or two grades. During the dry season, the COD and NH3-N concentrations will meet grade IV and grade V standards, respectively, after 50 mVs of flow is pumped from the Yangtze River. During the flood season, the COD and NH3-N concentrations will meet grade III and grade V standards, respectively, after 60 mVs of flow is diverted from Shijiu Lake. These research results can provide references for integrated environmental regulation and operation of water diversion of the external Qinhuai River.关键词
