Asphalt VOCs optimal control pollutant screening method and application thereof

Abstract

The invention discloses an asphalt VOCs optimal control pollutant screening method and application thereof. The method comprises the steps of acquiring, detecting and analyzing an asphalt VOCs sample to obtain asphalt VOCs substance composition and content; selecting an asphalt VOCs environmental pollutant list according to the definition of VOCs and the environmental influence degree; according to corresponding chemical differences of different substances on ozone generation potentials, secondary aerosol generation potentials, health risk assessment and the like, quantifying asphalt VOCs environmental influence risk assessment; and performing priority ordering on the comprehensive influence effects of different substances in the asphalt VOCs by adopting an information entropy method to obtain priority control pollutant details of the asphalt VOCs. According to the method, the defects that a conventional pollutant screening method is high in subjectivity, not comprehensive in screening index and the like are overcome, the environmental influence degrees of different substances can be objectively and quantitatively evaluated by integrating multiple dimensions such as environment and human body harm, and the method is more suitable for pollutant screening research in the atmospheric environment.

Description

technical field [0001] The invention belongs to the technical field of VOCs optimal control pollutant screening, and in particular relates to a method for screening asphalt VOCs optimal control pollutants and an application thereof. Background technique [0002] Air pollution is a huge environmental problem faced in the process of rapid economic development and urbanization, which seriously endangers human health and the harmonious development of the ecological environment. VOCs, as important precursors for ozone and PM2.5 generation, have received more and more attention. [0003] Asphalt material is an important source of VOCs emissions, and its composition is very complex. Due to the late start of the prevention and control of VOCs in my country, there is no special detection and evaluation standard for asphalt VOCs. The prevention and control objects are not unified. It is more difficult. Restricted by existing technologies and testing methods, it is impossible to condu...

Problems solved by technology

However, relying on the expert scoring method, there are relatively large human factors, and at the same time, there is still a certain gap between the current research level of our country and the research level of foreign countries.

[0005] At the same time, at present, the research on priority pollutants in my country is mainly concentrated on the water body environment, and the related research on asphalt VOCs has not been reported.
