Water Pollution Prevention and Control Grade Evaluation Based on Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation

Abstract

With the rapid development of economy, the continuous growth of industrial and agricultural production demand and the rapid growth of the world population, Water Pollution (referred to as WP for convenience) has become one of the most important and urgent environmental problems for mankind. However, WP has become increasingly serious in the process of development, such as changes in the natural environment and the operation of social systems. This would not only aggravate the contradiction between supply and demand, but also affect environmental protection and economic development. Therefore, it is urgent to explore ways to reduce regional WP and strengthen the control and protection of water resources. Therefore, by analyzing the basic requirements of WP prevention and control, this paper studied the control unit of prevention and control, and then analyzed the standards of WP prevention and control. Finally, the corresponding control strategies were proposed. By comparing the specific effects before and after WP control, it could be seen that the treatment effect after WP control was 10.9% higher than that before. The degree of subordination was 10.3% higher than that before control, and the environmental bearing capacity was 11.4% higher than that before control. In short, the prevention and control of WP was of great significance to the development of environment and economy.
