Preliminary Study On Bitter Salty Water Resources Evaluation And Use Of Huanghua

HuangHua is one of acute water shortages areas in China. With the development of national economy and the rapid population growth, the demand for water is increasing, too. Because of special Hydrogeology conditions in HuangHua, shallow bitter salt water whose degree of mineralization and fluorine is on the high side, is widely distributed in the local. We cannot directly use this kind water in the industrial, agricultural production and daily life. Surface water resources can not meet the water consumption growth, and shallow water cannot directly use, so that a large number of deep groundwater are exploited. With the increasing of deep groundwater exploitation, the deep underground water level declined year by year, which lead wells depth grown and grown. The cost of drawing water is increasing day by day, which result in agricultural benefit down. At the same time, groundwater exploitation also causes a series of ecological environmental problems, for example, groundwater level descending lead to ground settlement and seawater intrusion. Some rural areas which are covered with bitter salt water, they have to drink the bitter salt water which do harm to people’s health. This phenomenon restricts the economic and social development and damages the ecological environment. In order to alleviate the local water resources crisis, make the local water resources sustainable utilization, and improve the local ecological environment, exploitation and utilization of non-traditional water resources is an effective measure. Exploitation of underground salt water is one of effective measures, because it can change to "waste" for the treasure, reduce harm, increase water resource and improve the environment. The reasonable evaluation of its resources is the premise of development and utilization of bitter salt water resources, on this basis to explore the way of bitter salt water.The main contents of this paper are as follows: (1) Divide different salinities bitter salt water, analysis the limit of using water salinity in the industrial, agricultural production and daily life. Define the standard of bitter salt water, analysis the characteristics of bitter salt water resources, put forward the concept of bitter salt water resources. (2) According to relationship between the groundwater recharge and discharge, study the groundwater system of bitter salt water resources in HuangHua. According to the study of underlying surfer distribution cal condition, divide and analyze the groundwater system; Analyze the cause of bitter salt water, storage conditions, and the distribution in horizontal and vertical direction; Analyze the relationship of bitter salt water resources groundwater system between input and output. Based on the above analysis, generalized the bitter salt water resources groundwater system.(3)The determion of hydro-geological parameters. According to bitter salt water resources ground water system in Huanghua, Analyze the effect of precipitation infiltration recharge coefficient, irrigation field infiltration coefficient, and diving evaporation coefficient on this system. Consult related materials and choose the suitable hydro-geological parameters. (4) The evaluation of bitter salt water resources. According to the certain hydrogeology parameters, Subentry calculate the supplying and egesting of different mineralization bitter salt water resources .Combined with the actual situation in the study area, select appropriate exploitation coefficient, Calculate the available different mineralization bitter salt water resources. (5) According to the available different mineralization bitter salt water resources and the distribution of different mineralization bitter salt water resources, gain the distribution rule of bitter salt water resources. (6) Bitter salty water resources utilization. Based on the use of bitter salt water resources in the industry, agriculture production and dairy life, analyze application of the different mineralization bitter salt water resources in agriculture, industry, lives, breeding industry, and the planting industry.
