Water environment early warning index system in Tongzhou District

Abstract

Water environment early warning is an effective mean to predict and evaluate the impacts of droughts or water pollutions and provide a basis for decision-making to relieve the damage, which will be beneficial to social security and economic development. Taking Tongzhou District, Nantong City as the research area, this paper established a water environment early warning system based on Microsoft Visual Basic 6.0, the main functions of which include gradual changing and sudden water environment early warning modules. Then the paper simulated an industrial wastewater leakage accident in Tongzhou District and calculated the influence time, influence scale and warning level. The result demonstrates that this early warning system is practicable and can be applied to provide technical supports for relevant departments to take emergency measures.
