Embodiment Construction

[0030] The technical solutions in the present invention are clearly and completely described below in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] Such as figure 1 As shown, a kind of construction and the judging method that the fugitive dust emission of stockpiling site exceeds the standard provided by the present invention comprises:

[0032] 1. Collect the particle concentration values ​​at the monitoring points of construction and stockpiling sites.

[0033] Due to the frequent traffic of vehicles at the entrance and exit of vehicles, the dust emission is more serious. Therefore, the monitoring point is set ...

Abstract

The invention discloses a method and a system for judging standard exceeding of flying dust emission of a construction and stacking site. According to the invention, any time period and any day are taken as a period; the average particulate matter concentration value in any time period and the daily average particulate matter concentration value in the current day are calculated; the correspondingjudgment basis is the particulate matter concentration value published by the official department in the any time period and the particulate matter concentration value of the day; and the judgment basis is changed in real time, and the judgment basis of real-time change is adopted to judge whether the flying dust exceeds the standard within any time period or not and judge whether the flying dustexceeds the standard within the current day, so that the judgment of the standard exceeding conditions of the flying dust is more reasonable and accurate.

Description

technical field [0001] The invention belongs to the technical field of dust pollution control in construction engineering, and in particular relates to a method and system for judging that the dust discharge in construction and stockpiling sites exceeds the standard. Background technique [0002] Flying dust is an open pollution source that enters the atmosphere due to the dust on the ground being driven by wind, man-made or other drives, and is an important part of the total suspended particulate matter in the ambient air. In order to control the emission of dust, some construction and stockpiling sites have installed particle sensors for dust monitoring. At present, there are two methods for judging that the emission of fugitive dust exceeds the standard: one is to refer to the concentration limits of the basic items of ambient air pollutants in the "GB3095-2012 Ambient Air Quality Standard" (see Table 1). When the particle sensor detects that the current particle concent...
