Relevant data statistics of the end of Nantou County's "108 Annual Nantou County Zhushuixi Upstream Coastal Washing and Cleaning Program" statistics were carried out from March 06, 108 to December 31, 108. A total of 60,370.8 kilometers of street washing were performed. 62,348.56 metric tons, total TSP reductions were 833.12 metric tons, and PM10 was 157.0 metric tons. The water consumption partly meets the requirements of the Environmental Protection Agency-Street Dust Cleaning Manual recommended water consumption (> 0.9 ton / km). In addition, drainage holes were cleaned up and soil weed removal was carried out. The total amount of waste soil removal was 38.84 tons. The purpose was to improve the water removal and water accumulation of street washing vehicles. In order to increase the effectiveness of street washing operations, a traffic monitoring management system is used to understand the driving dynamics of the street washing vehicles (such as the driving route, time, speed, and direction of the street washing vehicles), so that supervisors can effectively monitor the quality of the execution operations. In addition to the traffic monitoring and management, this plan also inspects street cleaning operations on the spot every month. The execution of the plan until December 31, 108 is "clean", indicating that the site operation is in good condition. During the planning period, 4 samples of TSP and street dust load tests are performed each season. The test results show that the TSP reduction rate after street washing is between 13.0 and 64.4%, and the TSP concentration before and after street washing is easily affected by the surrounding environment. There is a significant difference in the measured values; the total street dust load reduction rate of each test is between 60.7 and 66.8%, and the road pollution level can be improved to A level after street washing; street washing operations have a direct and immediate reduction in street dust load effect. Cooperate with the Environmental Protection Agency to promote road adoption, and through face-to-face communication with representatives of enterprises, increase the manufacturers' willingness to adopt. The target of adoption is river dredging project manufacturers. In addition to informing the implementation philosophy and requirements, they also establish their own independent commitment adoption mechanism. In terms of effectiveness evaluation, road inspections are performed monthly, and street washing routes and street washing frequencies are arranged according to the results of the inspection. Since the implementation of the plan, a total of 27 manufacturers have been engaged in the adoption operation. The focus of this work item is to use inspections to improve the effectiveness of cleaning and cleaning. In good condition. In addition, the plan uses source control to enhance the effectiveness of street washing and reduce street dust, and conduct pollution surveys and classifications for sections of the Taiwan 16 line and industrial transportation roads. The monthly survey results are submitted to the Environmental Protection Agency and related plans to improve street cleaning vehicle cleaning performance by joint control. If serious pollution is found during the investigation, the relevant authorities shall be notified immediately by telephone, and the manufacturer shall be requested to improve and reduce the pollution. The plan is to conduct regular visits to village heads along the Xiejie section to understand the needs of local residents. As of December 31, 108, the leaders of the interviewed villages had positive reactions and affirmations to the street washing operation of the project. The opinions of the relevant village chiefs, if not within the scope of the plan, will be reported to the relevant plan horizontally after the reorganization or transmitted to the responsible unit by post.
