Grey correlation analysis on factors affecting industrial water pollution in Jiangsu Province

摘要

Industry is the main industry of water pollution. we should reduce the total amount of industrial water pollution to enhance the overall quality of the environment. Taking Jiangsu as an example, this paper analyzes the factors that affect the industrial water pollution by using the grey correlation analysis method. The results show that, in accordance with the influence factors for industrial water pollution from big to small order, influence factors are as follows: Engineering and technical personnel number; industrial wastewater treatment investment; industrial energy consumption; industrial electricity consumption; gross value of industrial output. Therefore, to enhance the Jiangsu Province's industrial wastewater pollution control level, we need to focus on following aspects: increasing number of engineering and technical personnel; the increase in investment in industrial wastewater treatment.we also need to take effective measures to reduce industrial energy use and industrial use of electricity.
