The project of Evaluation of Natural Treatment Sysetems (NTS), 2010 executed from May 28, 2010 to February 28, 2011. Contracted working items are summarized as follows:
1.The scheduled maintance of four NTS systems are concluded in the following table 1:
Table 1: Summary of Scheduled Maintenance
Item Hong-Lo North-Eastern Converging Entrance Huo-Shaso-Ping Tong -Xin -Hu
Total Patrols 44 44 50 44
Reported Defects 23 20 80 19
Improved Defects 23 20 80 19
Analyzed Water Quality Sample 5 4 9 7
Gathered and Removed Aquatic Plants (times) 2 2 2 2
Replanted Aquatic Plants (times) 1
Analyzed Sediments Samples (times) 1 1
Ecology Field Methods (time/season) 4 4
(1)Huo-Shaso-Ping water quality analysis changed from once per season to once per month as contract requested.
(2)Tong -Xin -Hu water quality analysis set up multiple sampling spots during rainstorm period. Due to the facility shut down, the influent water quality had obviously improved by comparing with pervious water quality statistics. (1997, 1998, 1999, 2000)
(3)This project proceeded sediments analysis on Huo-Shaso-Ping and Tong-Xin-Hu, compared to the project of 1997, the statistical date didn’t show an obviously difference. However, the Huo-Shaso-Ping appeared polluted worst than before.
(4)This project authorized Prof. Tung, Shu-Chu, Department of Environmental Engineering, Kun Shan University, to proceed ecology field method with Peng-Hu Wetland Protection Association.
(5)Set up aquatic plant separation zones in free water surface system of Huo-Shaso-Ping to avoid aquatic plant overgrowth on water surface.
2.The management and maintenance on reclamation facility of Penghu Prison and Nation Penghu University
Item Nation Penghu University Penghu Prison
Analyzed Water Quality Sample (times) 4 5
Analyzed Water Quality Sample on Factory life Wastewater Reclamation System (times) 4
(proceed 3 times during this project period)
The difference between the past projects:
(1)The first factory life wastewater reclamation system was constructed on the end of 2009 and second system was implanted this year. Therefore, this project assisted on analyzing water quality sample and provided suggestion on operation and maintenance such as added CALCIUM HYPOCHLORITE Tablet.
(2)Assisted Nation Penghu University on improving water pipeline connection.
3.This project assisted Communication Barrack of Army’s NTS facilities to meet standard of EPA’s inspection. During this project period, we proceed four times water quality analysis and listed the relative maintenance budget.
4.Assisted on inspecting Cheng-Kung Reservoir by using North-Eastern
5.Converging Entrance gravel stone filtration system in order to analyze influent and effluent water quality and water pollutants reducing
Taiwan Water Corporation pumped 2,800 tons water from Cheng-Kung Reservoir in the dry season which from November 9, 2010 to January 30, 2011. In order to purify water quality, the water flow through North-Eastern Converging Entrance’s underground infiltration tank under NTS facility. This project assisted on analyzing influent and effluent water quality once a month and one scheduled sampling, total four monitoring
6.Moreover, we carried out the non-point and point source on-site inspection, and analyzed 5 spots of influent water quality. According to the result of analysis, we calculated the amount of Cheng-Kung Reservoir pollutants and illustrated in Cause-and-Effect diagram.
7.Hold an activity on subject of understanding Huo-Shaso-Ping NTS facility on February 21, 2011.
