Chemical enterprise wastewater chemical pollutant special factor list construction method and device

Abstract

The invention discloses a chemical enterprise wastewater chemical pollutant specific factor list construction method and device. The method comprises the steps of determining a reference variable of a wastewater pollutant yield balance basis; establishing a wastewater pollutant output balance model, wherein the balance model is associated with each discharge port; obtaining related information of each reference variable according to the balance model; calculating the total pollutant generation amount of each discharge port; obtaining enterprise pollutant reduction quantity; calculating the pollutant discharge amount of each discharge port according to the pollutant discharge amount = the sum of the total production amount - the reduction amount, and constructing a wastewater pollutant balance data list; and constructing a wastewater chemical pollutant characteristic factor list according to the wastewater pollutant balance data list. According to the invention, complex wastewater production and discharge conditions of enterprises are changed; according to the method, effective and clear-level balance calculation is carried out according to the output volume balance calculation process, so that a waste water pollutant balance calculation data list can be constructed, a clear waste water chemical pollutant characteristic factor list is constructed, calculation of pollutants at all levels in different scenes is realized, and identification of specific components of the pollutants and analysis of a pollution source can be obtained according to the output volume balance calculation process.

Description

technical field [0001] The invention relates to the field of information analysis, in particular to a method and device for constructing a list of special factors of chemical pollutants in chemical enterprise wastewater. Background technique [0002] Chemical industry is the pillar industry of the national economy, accounting for more than 10% of the industrial GDP of the national economy. Focusing on the Yangtze River Delta region, the chemical industry is one of the pillar industries in the Yangtze River Delta region. There are more than 60 chemical parks in the Yangtze River Basin, with about 2,100 production enterprises, and the chemical output accounts for 46% of the country. In addition, the chemical industry is also a pillar industry in Jiangsu Province. The output value of chemical industry accounts for about 13% of the total industrial output value of the province. There are 53 chemical industry parks above the provincial level. The organic wastewater discharged by...

Problems solved by technology

Most of these chemical pollutants have the characteristics of ecological and health hazards, and become potential sources of ecological and environmental risks.

At present, the terminal treatment strategy based on comprehensive pollutant indicators such as COD cannot effectively reflect the toxic characteristics of wastewater, and has been unable to fundamentally control environmental risks. It is urgent to establish a list of characteristic factors of wastewater pollutants in chemical park enterprises from the source.

[0004] However, the reality is that due to the large variety of wastewater discharged by enterprises, accounting is difficult, and there is very little analysis of the list of characteristic factors of chemical pollutants discharged by enterprises. Instead, comprehensive pollutant indicators such as COD or volatile phenols, anilines, A general category of pollutants such as nitrobenzene to characterize the category of wastewater pollutants, which cannot meet the requirements of refined environmental control
