中文摘要 | 大陸東南沿海地區是大陸對外開放最早的地區,也是許多臺商鍾愛的投資地點, 在大陸和臺灣的礦產品貿易上,由於東南沿海地區與臺灣距離近,佔有地緣優勢,目前已出 口了多項礦產品到臺灣,約佔自大陸進口礦產品總量的 87 %,因此本研究乃以東南沿海地 區的福建、廣東、海南三省作為研究的對象,深入探討當地的礦產資源概況及分析其礦產投 資環境,以期對政府有關單位擬定兩岸礦產資源合作與貿易政策,或臺商未來在此三省從事 礦產資源的投資或合作,提供重要的參考依據。研究結果顯示,目前若前往福建省投資非金 屬礦產,由於其高嶺土、石英砂、葉臘石、矽輝石、長石、及花崗岩材等礦產,具儲量足、 地質開發潛力佳、市場需求持續成長、及產地交通方便等優點,故為較佳的礦產投資選擇。 由於廣東省在探明的礦產資源中除了硫鐵礦、高嶺土、石英砂、膨潤土、及石灰石在地質調 查及應用上有較深入的研究外,大多數的礦產地質調查工作及應用發展仍不足,故目前能立 即合作開採的有部份大型高嶺土、冶金白雲石、破璃砂、鈉鹽、芒硝、輝綠岩、及花崗岩石 材等。海南省的石英砂礦、建築砂石、及花崗岩等礦產,具儲量豐富、分佈廣泛、及品質佳 等優點,目前也都有出口到臺灣,是可考慮投資的礦產項目。 |
英文摘要 | Creating a closed water system at a paper mill could improve the efficiency of water use during manufacturing, reduce the mill's dependence on ground water, and eliminate discharge waste water. From integrated papermaking in the laboratory, tests showed that instituting a closed loop system could save 54.5% water. A water recycling system consisting of pumps, tank and treatment system were designed. In general, the paperboard mill used some practical methods for saving water, for example, enlarging the gozzle distance from 50 to 150 cm, decreasing the number of nozzles from 9 to 5, and reducing the water pressure from 20 to 10 kg/c ㎡ during operation. Treated white water containing 45 ppm. of suspended solids was recycled. Finally, in a closed white water system, 55% of water consumption is saved. A successful run using a closed water system producing 400 tons/day paperboard could produce savings of NTD37,930 per day. |
