Water quality information calculating device and water quality information calculating method

Abstract

The invention provides a water quality information calculating device and a water quality information calculating method, which are used for simulated calculation of the concentration of pollutants in water pollution accidents. The water quality information calculating device comprises an information input module, a calculating module and a display module, wherein the information input module is used for inputting information reflecting the concentration of pollutants on the cross section of an upstream river; the calculating module is used for calculating the concentration of pollutants polluting the water quality of the cross section of a downstream river by means of a two-dimensional water quality simulation system dynamics model according to the input information of the information input module; and the display module is used for displaying the information inputted by the information input module and calculated results outputted by the calculating module. The water quality information calculating device has the advantages that system dynamics is applied to dynamic simulation research on water quality variation of the water pollution accidents, the two-dimensional water quality simulation system dynamics model is established, dynamic analogue simulation is performed for concentration variation of the pollutants in the rivers caused by convection, diffusion, physical, chemical and biological processes such as attenuation and the like resulting from chemical reaction and biological absorption, and then the concentration of the pollutants on the downstream cross section can be predicated.

Description

technical field [0001] The invention relates to the technical field of water quality analysis, in particular to a water quality information calculation device and method. Background technique [0002] In recent years, major water pollution accidents have occurred frequently in my country, which have seriously affected the ecological environment, people's health and social security. For example, the Songhua River water pollution accident in November 2005 and the Guangdong Beijiang cadmium pollution accident in December 2005 are typical cases of major water pollution accidents. In the emergency process of water pollution accidents, it is urgent to grasp the temporal and spatial distribution of pollution zones and the concentration of pollutants, so as to formulate emergency response strategies quickly and effectively. In order to meet the requirements of rapid disposal of water pollution accidents, combined with the actual monitoring data at the accident site, the mathematica...
