(7) Innovative practices - application of direct reading instruments for granular pollutants
In order to strengthen the pollution control of construction projects, local environmental protection bureaus in various counties and cities have introduced a number of innovative monitoring practices in recent years to monitor, stalk and control the construction projects of different types of projects and situational needs, including large-scale construction engineering real-time monitoring systems. The triggered monitoring mechanism assists in monitoring the site pollution and the time-lapse camera for continuous monitoring of short-term maneuvering construction activities to promote the efficiency of the inspection and control and to relieve the manpower control load. However, such tools are monitored for end-polluting behaviors and phenomena. Once an abnormality is discovered, the pollution has become a reality, although it helps to reduce the impact of pollution, but the damage to environmental quality has also formed. Therefore, from the perspective of early warning, if the data can be collected through continuous monitoring, the air quality at the location of the construction project can be mastered, which will help to immediately intervene in the adoption of contingency measures. Therefore, this year, we intend to use the direct-reading aerosol detector to monitor the PM2.5 concentration in small-scale areas during the inspection (inspection), and to enhance the active early warning capability under the existing air quality deterioration and response mechanism:
1. Mastering the construction of large-scale construction projects
The high-contamination stage of the project comes from the excavation and planing operations of dredging projects, construction and road engineering, etc., which are the largest sources of pollution emissions. In order to prevent air quality deterioration, large-scale construction projects such as dredging, construction and roads are required. Construction project, construction area of 5,000 square meters of dredging and road works) Real-time monitoring of PM10 and PM2.5 mass concentration. Currently, 10 large-scale projects are selected according to the Environmental Protection Department's A2010 construction project pollution control and charge management information system. Conduct this year's immediate quality concentration monitoring control targets.
2. Direct reading aerosol detector detection operation planning
For mass concentration analysis of PM10 and PM2.5, the detection range is 0.001 to 400 mg/m3, set the average concentration every 10 seconds, the detection time is 1 hour, and record the weather conditions of the wind anemometer on the upper and lower winds. Each time, different pollutants were tested at different times. After the test, the personnel performed the maximum, minimum and hourly average statistics for the monitoring results on the day.
3. Comparative analysis of the concentration value data of Hualien station
Before performing concentration monitoring on the same day, go to the Environmental Protection Department Hualien Monitoring Station for simultaneous monitoring and comparison to confirm the machine hour average concentration difference, and use the average difference value of the Hualien station and the detector synchronous detection data as the current day. Measure the concentration measurement value, verify the measured value in this way, and use it as the reference value of the accuracy and accuracy in the measurement process to reduce the occurrence of excessive comparison value. When the comparison value is within ±10%, the measurement value will be adopted. Data usage analysis, if it is exceeded, re-measure and calibrate to ensure that the measurement results will not exceed ±10%.
4. Concentration warning combined with aerial shooting to strengthen prevention and control
According to the monitoring results, grasp the situation of site pollution change, strengthen the prevention and control system in advance, coordinate the on-site strengthening of the traffic lanes, bare ground surface, etc., strengthen the watering, increase the frequency of entrance and exit cleaning, earthwork and materials to strengthen the net and other defense operations, and through the air Shooting methods, grasp the location and area where dust is easy to be raised, and strengthen the prevention of regional or road sections.
5. This year, 10 construction sites have been completed for monitoring: Zhang Yiyi's shop residence, office demolition project, 0206 earthquake disaster, old Far East department store demolition project, 106 Hualien River water system Hualien River and tributary Shoufeng River confluence near the river Dredging project, Zhou Hongtao illegal construction demolition project, new construction project of Hualien Xiang Er Wen Chuang Hotel, county 193 line 17k+300~19k+840 (Nanbin to Nanhai 4th Street section) section widening project (road widening and drainage project), Hualien County Youth Relief and Family Housing New Construction (Phase I) Turnkey Project (Construction Project), 106 Hualien River and Wanlixi Confluence Dredging and Separation of Earth and Stone Mining (Expenditure), Meilunshan Park and Mambo Park 0206 Earthquake Reconstruction project, 10 projects including Nanpu 8th Street, Renli 1st Street and 3rd Street Rainwater and Underwater Channel Project in Ji'an Township, Hualien County.
In order to understand the current sampling difference between the direct reading instrument and the Hualien station, the sample will be sent to the Hualien station for one hour average comparison before sampling. The simultaneous sampling results of the direct reading instrument hourly average PM10 and PM2.5 respectively It is 0.019 mg/m3 0.003 mg/m3, and the hourly average PM10 and PM2.5 of the Hualien station are 35 ug/m3 and 2 ug/m3. The sampling result of the direct reading instrument is converted into ug/m3, and the PM10 is 19ug/ M3 and PM2.5 is 3 ug/m3, and the difference between PM10 and PM2.5 is 46% and 50%, respectively. However, due to the problem of equipment scheduling, the number of samples in the Hualien station is not enough, and there is still a large amount in the sampling value. The error can only be used as a reference indicator for on-site pollution. The average number of differences between Hualien station and direct-reading instrument is calculated. The average value is used as the reference value for the reduction to understand the actual pollution discharge and controlled emissions of the site. The difference. After the completion of the above-mentioned 10 sites, the PM10 of the comparison before and after the control was 451 ug/m3, the reduction was 58 μg/m3, the reduction was 13%, the PM2.5 was 146 ug/m3, and the reduction was 21 μg/m3, which was reduced by 15%.
