(1)Execution of street flushing
The total length of road washing operations in this project was 70,553.8 kilometers, and the midterm progress attainment rate was 100.8%. The total water consumption for street washing was 73,901.29 tons. The average monthly water consumption per unit length (km) was 1.04 metric tons. The average unit water consumption was also the same, which was greater than the contractual water consumption. Estimated according to the reduction factor of the Environmental Protection Agency, TSP can be reduced by 973.6 metric tons, PM10 183.4 metric tons, and PM2.5 42.8 metric tons.
(2)Water quality testing
The project planned a total of 20 qualified discharge water intake points. Water quality testing operations will be carried out in June 2023、 September 2023. and December 2023.The suspended solids (SS) concentration at the water intake points will be between <2.5 and 50.0 mg/L. The dissolved oxygen (DO) is between 2.9 and 8.4 mg/L, and the hydrogen ion concentration (pH) is between 6.9 and 8.8. Except for the dissolved oxygen (DO) of the Anping Water Resources Recycling Center, which does not meet the standards, it has been The samples were taken for re-inspection on July 11, 2023, and passed the test; the test results of other street washing water are in line with the water specifications of this plan.
(3)Road dirt survey
Carrying out road pollution survey operations. A total of 1,292 road surveys were completed, totaling 4,333.66 kilometers, of which a total of 1,176 A-level roads, totaling 3,841.66 kilometers (accounting for 88.6%); A total of 116 B-level roads, totaling 492 kilometers (accounting for 11.4%); and there was no C-level road. In addition, B-level roads had been horizontally notified to the district team, pigging department, and other units to be included in the cleaning range.
(4)Performance evaluation for the street flushing.
The evaluation of the effectiveness of street washing was carried out by the use of street dust detection and analysis. Completed two quarters of detection and analysis on June 6 and 7、September 12 and 13, 2023、December 5 and 6 ,2023 and March 5 and 6 ,2024, a total of 4 roads with 96 points. Before the street washing operation in the four seasons, the average street dust load was 0.7981 g/m2, and the soil load was 0.2322 g/m2. After the street washing operation, the average street dust load decreased to 0.3495 g/m2, and the soil load was 0.0869 g/m2. The reduction rates of street dust and soil from street washing operations were 56.2% and 62.6%, respectively.
(5)Collection of cleaning operations in this city
This plan regularly collected the implementation data of various cleaning operations in this city every month, with a total of 422,275.91 kilometers (include corporate adoptions 38,561.01 kilometers) in total length of the city’s cleaning operations. It was calculated according to the formula for reducing TSP, PM10, and PM2.5 through street cleaning operations stipulated by the Ministry of Environment. It was estimated that TSP could be reduced by 5,295.3 metric tons, PM10 by 997.7 metric tons, and PM2.5 by 232.9metric tons. (The reduction coefficient is estimated for mechanized cleaning operations, and since corporate adoptions mainly use manual labor, they are not included in the calculations.)
(6)Agricultural Pollution Bulletin
According to the resolution of the consultation meeting on the division of labor, 15 high-density farming areas (Houbi District, Liuying District, Xinying District, Xiaying District, Dongshan District, Baihe District, Yanshui District, Liujia District, Guantian District, Xinshi District, Jiali District, Madou District, Guiren District, Shanhua District, and Xigang District) a total of 45 agricultural demonstration road sections, and A total of 225 inspections were carried out during the implementation of the plan
(7)Active control measures
A. Emergency response measures against air quality deterioration
B. Assist the bureau to carry out various publicity operations
C. Analyze the changing trend of PM2.5 concentration by micro-sensor and traffic station.
D. Cooperate with the Ministry of Environment to notify the cleaning operation of the air pollutant emission control and reduction plan of fugitive pollution sources.
