Burst water pollution event monitoring and pre-warning system

Abstract

The invention discloses a burst water pollution event monitoring and pre-warning system which comprises an automatic sampling system, a monitoring system, a data transmission system, an information management system and a water pollution forecasting model system, and is characterized in that the automatic sampling system is provided with a water sample three-grade desanding treatment device and adopts a section flowing and multi-point circulation sampling mode; the water pollution forecasting model system establishes a pollutant leakage simulation model and an eutrophication forecasting model; the information management system establishes a monitoring station and a control center station; the automatic sampling system, the monitoring system and the water pollution forecasting model system are respectively connected with a central control unit in the monitoring station of the information management system; and the automatic sampling system is connected with the monitoring system and the water pollution forecasting model system respectively. The burst water pollution event monitoring and pre-warning system breaks through the conventional key technology; a multi-item system comprising the automatic sampling system, the pollutant leakage simulation model, the eutrophication forecasting model and the like is researched and developed; and system integration is implemented.

Description

technical field [0001] The invention relates to the field of sudden water pollution incident processing, in particular to a monitoring and early warning system for sudden water pollution incidents. Background technique [0002] With the continuous development of social economy, the problem of environmental pollution is becoming more and more prominent, and sudden environmental pollution accidents are also increasing, such as the arsenic pollution incident caused by the wastewater discharge of Hunan Yueyang Chemical Plant in 2006, the Taihu Lake water pollution incident in 2007, and the Yancheng water pollution incident in 2009. The factory raw water was polluted by phenolic compounds, Fujian Zijin Mining toxic waste water leaked in 2010, etc. In addition, some sudden pollution accidents occurred abroad, such as the Gulf of Mexico oil spill, the Hungarian aluminum factory toxic waste water leak, etc. These pollution accidents Strong suddenness, rapid spread, large impact, and...

AI Technical Summary

Problems solved by technology

[0004] Sudden emergency monitoring has the following two characteristics: first, it is unpredictability, including the location, time, pollution factors, etc. of the accident, etc.; second, it is multidisciplinary. It also determines the multidisciplinary nature of monitoring work. Therefore, emergency monitoring is a serious and complicated task. The monitoring department can no longer solve various problems well by relying only on traditional manual inspection and methods. There is still a lack of research on general theories and methods for building regional water environment safety monitoring and early warning systems, and the existing early warning systems do not systematically reflect the profound relationship between water environment safety and regional social and economic development.
