Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
There are two methods for determining the sensitivity of ozone generation: firstly, a model OBM mode based on observation is utilized, a large amount of observation data (VOC, NOx and meteorological data) are input for calculation, the data volume is large, and codes and models need to be mastered; and secondly, the modes such as NAQPMS, WRF-CMAQ and the like are utilized to simulate the generation response condition of the ozone concentration by changing the list to judge that the ozone generation is more easily controlled by the substance, and the method needs a high-resolution pollution source discharge list as the most basic input parameter, needs to consume a large amount of computing resources and time, and needs a model application technology.
Based on this, the embodiment of the invention provides a method and a device for judging ozone generation sensitivity based on observation data, so as to solve the technical problems of large amount of early observation data, high consumption of computer resources and high calculation difficulty in the prior art.
To facilitate understanding of the present embodiment, first, a detailed description will be made of a method for determining ozone generation sensitivity based on observed data disclosed in the embodiments of the present invention, referring to a schematic flow chart of a method for determining ozone generation sensitivity based on observed data shown in fig. 1, which can be executed by an electronic device and mainly includes the following steps S110 to S140:
s110: acquiring observation data of a plurality of continuous time periods, the observation data comprising: the concentration of VOCs and the concentration of NOx, and calculating the equivalent propylene concentration of VOCs in each time period based on the concentration of VOCs;
the observation data can come from current city monitoring point, and this city monitoring point can be used for realizing air quality or composition monitoring, and the observation data can include the concentration of VOCs and the concentration of NOx, and volatile organic compounds VOCs and nitrogen oxide NOx produce ozone after taking place the chemical reaction, are the main source of ozone. Therefore, the main influencing factors of the ozone generation can be judged firstly, and then the ozone pollution is reduced by controlling the main influencing factors in priority.
Volatile organic compounds VOCs generally include multiple species of VOCs, all of which may react to produce ozone, such as ethane, ethylene, benzene, and the like. The concentration data of the VOCs species can be obtained through the existing observation data, and the types and the number of the VOCs species collected by different monitoring sites are different.
The observation data is recorded in units of time periods, which are used to represent the time resolution, and may be one hour, ten minutes, one minute, or the like. Wherein, several continuous time periods constitute the observation period, for example, the observation period is one day, and the time period is one hour, then the observation data are the concentration of VOCs and NOx per hour in one day. The equivalent propylene concentration of VOCs is an index for indicating the atmospheric reactivity of VOCs, which refers to the ability of components in VOCs to participate in atmospheric chemical reactions and can be generally expressed by the equivalent propylene concentration, hydroxyl group (OH consumption rate), and ozone generation potential (OFP).
The observation data in this embodiment is based on VOCs, NOx and O of each city monitoring site3Concentration data in a certain time period does not need extra special observation, and does not need data support such as a high-resolution pollution source list and weather, so that the data acquisition is convenient, and the requirement on early-stage data is simplified.
S120: determining a first time period meeting a preset condition, and determining a first parameter based on the first time period;
wherein the first parameter is equal to a ratio of the equivalent propylene concentration to the NOx concentration over a first time period; the first time period is any one of a plurality of continuous time periods which meet a preset condition, for example, the observation period is 1-N time periods, the tth time period is the first time period which meets the preset condition, and the (T +1) th time period is the next time period adjacent to the first time period.
The preset conditions include: during the first time period and the next time period adjacent to the first time period, the increase in the equivalent propylene concentration is equal to the increase in the NOx concentration. As an example, the preset conditions include: during time T to (T +1), the increase in equivalent propylene concentration is equal to the increase in NOx concentration, and is formulated as:
At this time, T satisfying the condition is the first time period.
The increment of the equivalent propylene concentration indicates that the equivalent propylene concentration in the (T +1) th time period is higher than that in the T-th time period; the increase in the NOx concentration indicates that the concentration of NOx in the (T +1) th time period is greater than the concentration of NOx in the T-th time period.
As a specific example, if the first time period is determined as the tth time period, the calculation formula of the first parameter a is:
Wherein, eVOC(T)Indicating the concentration value of the equivalent propylene in the Tth time period; nox(T)Representing the concentration value of NOx during the T-th time period.
S130: calculating a second parameter, wherein the second parameter is as follows: an average of the sum of the ratios of equivalent propylene concentration to NOx concentration at each time period;
as a specific example, the calculation formula of the second parameter b is:
Wherein t is the time period, N is the number of time periods, eVOC(t)Indicating the concentration value of the equivalent propylene in the t-th time period; nox(t)Representing the concentration value of NOx during the t-th time period.
S140: the sensitivity of ozone generation is judged based on the first parameter and the second parameter.
Wherein when the first parameter is greater than the second parameter, then ozone generation is in the NOx control zone;
when the first parameter is smaller than the second parameter, the generation of ozone is in the VOCs control area;
when the first parameter equals the second parameter, then the ozone generation is in the transition or steady state region.
As an example, when the first parameter a > the second parameter b, the generation of ozone is in the NOx control region, indicating that the sensitivity of ozone generation in this region is primarily affected by the concentration of nitrogen oxides NOx in the atmosphere;
when the first parameter a < the second parameter b, the generation of ozone is in a VOCs control area, which indicates that the sensitivity of the generation of ozone in the area is mainly influenced by the concentration of VOCs in the atmosphere;
when the first parameter a = the second parameter b, the ozone generation is in the transition region or the steady-state region, indicating that the main influencing factor of the ozone generation sensitivity in this region is being converted from VOCs to NOx, or from NOx to VOCs, or the influence of VOCs and NOx on the ozone generation sensitivity is comparable.
The method for judging the ozone generation sensitivity based on the observation data can quickly judge the ozone generation sensitivity based on a small amount of existing observation data and simple calculation, can simplify the requirements on early-stage data, professional models, codes and the like, does not need model simulation, thereby reducing the consumption of hardware resources of computers and the like and improving the calculation efficiency.
In some embodiments, the step S110 includes the following steps shown in fig. 2:
s210: acquiring observation data of a plurality of continuous time periods, wherein the observation data comprises VOCs concentration and NOx concentration, and the VOCs comprises a plurality of VOCs species;
s220: calculating an equivalent propylene concentration for each species of VOCs for each time period based on the VOCs concentration;
as an example, the equivalent propylene concentration per species of VOCs per time period is calculated as:
Wherein the content of the first and second substances,
represents the equivalent propylene concentration of the VOCs species i,
denotes the concentration of VOCs species i, KiDenotes the reaction rate constant, K, of the reaction of the VOCs species i with the hydroxyl radical (OH)tDenotes the reaction rate constant of the reaction of propylene with hydroxyl radicals (OH), the constant KiAnd KtCan be obtained by reference to literature.
S230: and adding the equivalent propylene concentration of each VOCs species to obtain the equivalent propylene concentration of the VOCs.
As an example, the equivalent propylene concentration of VOCs
The calculation formula of (2) is as follows:
Wherein i represents a certain species i of VOCs; m represents the number of VOCs species participating in calculation, the M value can be different according to observation data acquired from city monitoring points in different regions, such as 57, 70 and 117, and the number of the species participating in calculation can be selected according to needs.
In some embodiments, the step S120 of determining a first time period satisfying a preset condition and the step of determining the first parameter based on the first time period includes:
step (A): determining a preset condition;
in some embodiments, the observation data further includes an ozone concentration, and the preset condition may include: in the first time period and the next time period adjacent to the first time period, the first ratio is equal to the second ratio;
the first ratio is the ratio of the increment of the ozone concentration to the increment of the equivalent propylene concentration; the second ratio is the ratio of the increase in ozone concentration to the increase in NOx concentration.
As an example, the preset condition is formulated as:
Wherein the content of the first and second substances,
the first ratio is a first ratio of the first ratio,
is a second ratio; t represents a single time period and (t +1) represents the next time period adjacent to the first time period. At this time, t satisfying the condition of equation (8) is the first time period.
The increment of the equivalent propylene concentration indicates that the equivalent propylene concentration in the (t +1) th time period is higher than that in the t-th time period; the increase in the NOx concentration indicates that the concentration of NOx in the (t +1) th time period is greater than the concentration of NOx in the t-th time period.
Step (B): determining a first time period meeting a preset condition;
step (C): determining a first parameter based on a first time period; wherein the first parameter is equal to a ratio of the equivalent propylene concentration to the NOx concentration over a first time period.
According to the method for judging ozone generation sensitivity based on the observation data, the concentrations of different VOCs species are converted into corresponding equivalent propylene concentrations, the VOCs concentrations are kept constant by using a unified index, and therefore urban ozone generation sensitivity can be judged more accurately; the sensitivity of ozone generation is judged based on a small amount of existing observation data and simple calculation, and the requirements on early-stage data, professional models, codes and the like can be simplified, so that the consumption of hardware resources such as computers is reduced, and the calculation efficiency is improved.
The embodiment of the invention also provides a device for judging ozone generation sensitivity based on observation data, which comprises the following structure shown in figure 3:
