Our team has completed the twelve times investigation of Yungheshan reservoir, the investigation was carried out for the background of the catchment and inflow stream of Lantan Reservoir and water quality of reservoir.
The sampling plan has fifteen sampling points around Renyitan Reservoir, Lantan Reservoir, and Pa-chang River.
According to the analysis result, it shows the point pollution sources and non-point pollution sources can be defined roughly. During the sampling period, we used the Vollenweider model to analysis the pollution hotspots in Lantan Reservoir and finished 128 times sampling.
By the investigation of pollution hotspots and the pollution Concentration Ratio (Delivery Ratio), we suggested that building the water purification facilities in the headrace channel between Renyitan Reservoir and Lantan Reservoir. Intensify the ability of water purification facilities in the headrace channel between zhushan weir and Renyitan Reservoir. Our team has collected the analysis result reports or study references of pollution hotspots of TP in middle Taiwan.
We have extended the cooperation with a local company, it was communicated about the research on combined purification tanks based on biological nitrogen removal and electrolysis units for removing nitrogen and phosphorus and performed the long-lasting test
By the test results, at the fourth stage of test, it was achieved the expected purpose that TN<10 mg/L and TP<2mg/L. In addition, we also supported to assess the combined purification tank using in the wastewater treatment facilities at the precast building. If the evaluation result had the completed relevant information and the function test, the combined purification tank could get the permit to use in the precast building.
On 2019 November 7, we went to the Hushan Reservoir with the director of the department for a site survey. Moreover on 2019 April 24 and October 15, we went to the Neihu wastewater treatment plant and Daxi Shunshipu for the combined purification tank test.
The part of an automatic boat, we have collected and organized the results we have performed, and wrote the promotional copywriting.
According to our analysis results, the water quality management method (CTSI) have been used is easier to overestimating the potential of Eutrophication. In order to check the current method EPA uses is suitable for the Reservoir management, we have proposed a calculation method for CTSI value correction; it was held an Expert consultation for revising the management of domestic water quality indicator on May 29, 2019. In order to assist EPA in setting the abnormal water quality tracking system, and to propose the improvement strategies for the 107 annual‘s Eutrophication Reservoir and Reservoirs at Jinmen and also hold a conference of businessmen for stakeholders.
Furthermore, according to the major four rules of NCKU Research and Development Foundation for the representative lake and reservoir sampling points, our team reviews the representative points at the Reservoirs in middle Taiwan and the inflow streams.
We have tracked and aggregated the results of Forward-Looking Infrastructure in Reservoirs, produced the lazy packages to provide agencies updating the information about Reservoir for the Forward-Looking Infrastructure on the website, and assisted to frame the 110 annual’s plan for strengthening the work of protection and management at catchment of Reservoirs.
