The environmental and ecological monitor and the distribution of heavy metal in the deposition in Matsu sea area Case in Nankan three desalination plant / 馬祖海域環境生態監測與沈積物金屬分佈以南竿三期海水淡化廠為例

碩士 / 國立臺灣海洋大學 / 河海工程學系 / 101 / "Private Participation in Matsu Nangan desalination plant construction and operation plan" by the Department to build desalination plants to provide water to solve the difficulty in obtaining the outlying islands of the problem; due desalination from weather effects, short construction period, the expansion of capacity respect, flexibility, small footprint and low impact on the ecological impact of advantage, and the output of desalinated water can be imported directly into local water purification plants with the pool, and then use tap water supply system serves users; coupled with nearly The constant breakthroughs in technology, it has become increasingly lower cost, and has been able to re-use by the engineering design and technology to ensure that desalination processes arising brine proliferation, reduce emissions estuary ecology seriously affected, suitable as a new water source and a stable Matsu region's future water needs.

The purpose of this study is to understand the "community involvement Matsu Nangan desalination plant construction and operation plan" during its surrounding seas working for environmental monitoring, the monitoring results collation, comparison and evaluation, the continuation of the pre-construction and construction periods environment background , the establishment of environmental quality in the vicinity of this area database to provide countermeasures and suggestions to improve the environment and as a water pollution control measures. The results showed that water monitoring results are in line with the CPI marine water quality standards and the protection of human health and the marine environment quality standards by the year CTD overall survey results show a good mix of water, water salinity concentration distribution is clearly affected by freshwater minimal. Bay station and the stations outside the context of the determination of parameters, the results are very close to the display discharge brine and the receiving water body exchange of good, did not find a high concentration of brine accumulation phenomenon. Measured values of heavy metals in sea water, in addition to copper, zinc and lead three kinds, the remaining stations measured values were measured value is close to the background. 2008 Matsu Nangan marine ecological environment assessment data show that the heavy metal content counties plotted comparison, we can see the heavy metal content of water Nangan Township, all of the content is low compared to other counties, and in the interests of the marine protection of human health Environmental quality standards (Cu: 0.3 mg / L, Pb: 0.1 mg / L, Zn: 0.5 mg / L, mercury: 0.002 mg / L). While the waters of the Minjiang River Estuary water is continental influence, but at the mouth of data compared to the counties have better water quality. Compared to other desalination plant, the desalination plant Nangan freshwater production is less than Seawater Desalination a desalination plant and other plants. Monitoring of heavy metals in sediments values are presented within the (discharge) less outside (background station) is now more than a phenomenon, presumably due to the background stand for Minjiang Estuary. Nankan desalination plant brine discharge waters are open space, and water yield is relatively low, the amount of brine discharge is also relatively low, so the brine desalination plant on marine ecology should be minimal impact on the bottom.
