Water Quality Assessment And Environmental Water Requirements Research On Xiaoqing River In Jinan

As China's social and economic development, industrial effluent and domestic wastewater emissions gradually increased, socio-economic progress of mankind in searching for economic benefits at the same time also had a negative impact on the environment. On both sides of the rivers in city as a result of urban population, industrial development and other factors, the water environment is deteriorating and gradually become the bottleneck of urban development. Xiaoqing River originates in Jinan City Mu Zhuang, in history has a flood control, drainage, irrigation, shipping, landscape, such as multi-functional artificial canals, had the world of "a long long Xiaoqing River in Shandong is a good place,". Xiaoqing River is the only transport to achieve the Haihe River, on the economic and played an irreplaceable role for social development along the route. Since the last century since the 70s, as a result of river basin's rapid economic development, people do not know the protection of the environment in place, resulting in a serious encroachment river, water reduction, industrial wastewater and domestic sewage discharge volume has increased year by year so that the Xiaoqing River water pollution, ecological the environment is deteriorating, Xiaoqinghe become worthy of the name "Little Black River," has seriously affected areas of Jinan City and socio-economic development along the river with the capital cities and regional central cities did not match the status of and damage the image of the provincial capital of Jinan City and the "Springs" of good reputation. Since the beginning of the Jinan Municipal Government in 2004 to carry out comprehensive treatment Xiaoqinghe the feasibility study will be integrated Xiaoqinghe remediation work put on the agenda.In this paper, as the source of the Xiaoqing River water diversion up a sub-topic issue on the current state of the Xiaoqing River water quality in doing a comprehensive evaluation of the Xiaoqing River after the completion of environmental remediation of water from two aspects of the one-dimensional and two-dimensional analysis.It take into account of different water sources , both sides of the progress of Pollution control project works and the volume of water supply for the Jinan City. It will give a suitable reference sources for Xiaoqinghe comprehensive management to choose the water sources.This paper is divided into water quality assessment and water quality simulation two parts. The Water Quality Assessment based on consider the current models and selected projection pursuit - Genetic Algorithm comprehensive evaluation model, the genetic algorithm to find the best projection direction and projection pursuit to determine the water quality of their water-level indicators. Water quality evaluation results show that the source of...
