The contract is dated from May 1, 105 to April 30, 2006, and the implementation time is 365 days, as follows:
(A) the river easy to dust exposed to the sand and sand industry inspections
Completed from May to April Hualien Creek, Li fog Creek and Xiugu Luan Creek along the easy to produce dust exposed inspection work. Completion of 12 ladder adjacent to Hualien River 21, Li fog Creek 1 and show Gu Lansi 1 sand and gravel industry inspections.
(2) Maintenance and monitoring of river dust early warning system
At present, the monitoring station is 99% efficient for the new city station, 98.15% for Hualian River and 99.15% for Xiukuluan River. The current efficiency is above 90%.
(C) Analysis of hydrological and dust events in rivers over the years
When the northeastern monsoon comes in October every year, it is easy to make the phenomenon of dust in the exposed field intensified. The analysis of the dusty events on the past year is easy to cause the climatic factors of dust. If the humidity is less than 70% and the wind speed is more than 4m / s, PM10 concentration increased.
(D) dust warning notification system
The PM10 automatic monitoring station is set up in Hualien Creek, Liwu Creek and Xiugu Lanxi Creek. The monitoring station samples up to 100 μg / m3 per hour, that is, send a warning message, if the concentration of 600μg / m3 and for two hours Above, immediately start the strain mechanism.
(5) Artificial grain sampling and composition analysis
During the period from September to February, the sampling work was carried out according to the schedule, and a total of five maneuvering operations were planned for the current year.
(6) river dust control propaganda briefing session and exercise exercise
At present the community and campus publicity briefing sessions have been completed for 6 sessions.
In order to improve the contingency mechanism of the river dust disaster in each unit, the dust pollution simulation is carried out every year before the flood season. This priority is given to the Guanghua Industrial Zone in the vicinity of Huainan River, which is aimed at the division of responsibilities for dust suppression. Was completed on September 20, 2005, the number of participants 154 people.
(7) unmanned carrier empty shot
On July 26 and January 16, 2006 on the implementation of the flood season before and after the air shot operations, and air images combined with the recent satellite imagery to assist in the allocation of water, green and bare location, and the river bed exposed to the Area calculation.
(8) river patrol team education and training and environmental clean-up operations
Combined with the county water patrol team jointly handle the river early warning notification education and training, for the team members to carry out the relevant skills training (such as assisting in monitoring, informing the area of the dust around the tour, etc.).
(September to the following year in February) for the washing of the street operations, location planning North and South Third District, respectively, for the new urban and rural areas, Shoufeng Township and Yuli District 2 times a week for the main road wash shop, the total annual 4,212 km, a total of up to 10.95 metric tons of PM10 reduction.
(9) page maintenance update
Has completed 12 times the page update and maintenance, update the project for the monthly activities of the message, the program monitoring station to monitor the background of the data maintenance and upload the implementation of the project results.
(10) innovation
The use of three-dimensional scanner emitter issued by the laser light, hit the plant, water or exposed to cause scattering and reflection of the signal, effectively grasp the river bed exposed terrain, landform, follow-up can help the relevant authorities to control the relevant planning.
