Rapid determine method for pollution degree of organic polluted places

Abstract

A related rapid determine method for pollution degree of organic polluted places comprises the following steps: step 1, preliminarily determining whether a place have volatile organic pollutants; step 2, arranging a soil gas sampling hole in the place; step 3, acquiring a gas in the soil, and performing on-site detection; and step 4, determining the pollution evaluation index value PI of the polluted place, and dividing the soil pollution grade according to the value. The method realizes rapid determination on the organic polluted place under the conditions of different places and different temperatures, and is applicable to places polluted by volatile organics. The method solves the defect that a conventional method for determining pollution degree of a place is long in consumed time, provides an effective approach for rapidly determining whether the place is polluted by organics on site, and also semi-quantitatively instructs the organic pollution degree.

Description

technical field [0001] The invention relates to a method for quickly judging the pollution degree of an organic polluted site, which belongs to the technical field of environmental evaluation. Background technique [0002] With the rapid development of social economy, the problem of soil pollution by organic matter is becoming more and more serious. Organic pollutants in soil usually exist in the form of gas phase, liquid phase and adsorption phase. Due to the complex forms and migration modes of various organic pollutants in the soil, it is very difficult to qualitatively determine whether there is organic pollution in the soil and to determine the degree of pollution quantitatively. [0003] Usually, inspectors take out soil samples and send them to the laboratory for testing, which takes a long time and cannot make quick judgments during the construction process. Moreover, in the process of transporting and storing samples, there may be the possibility of volatile organ...

Problems solved by technology

[0003] Usually, the inspectors take out the soil samples and send them to the laboratory for testing, which takes a long time and cannot quickly judge the needs during the construction process.

Moreover, in the process of transporting and storing samples, there may be the possibility of volatile organic compounds escaping, resulting in the consequence that the measurement result is lower than the actual value.
