摘要
苦滷係海水取鹽後之殘液的通稱。傳統苦滷除每公升含NaCl 160－200g外，並含豐富的鎂及鉀離子（每公升含MgCl_2 70－90g、MgSO_4 50－70g、及KCl 10－20g及少量鈣及稀有元素離子。目前台鹽每年約5萬公噸苦滷伴隨製鹽產生。國內與苦滷性質相近之海水延伸物尚有台鹽通宵廠之電透析苦滷，及未來海水淡化廠（如澎湖海水淡化廠）之排放液。此兩者雖成份與傳統苦滷不同，但均屬海水濃縮液，就資源利用言，屬同類產品應予資源化。本文說明台灣製鹽總廠近年在此方面努力所得成果，及本國未來從事海水化學工業，其工作規劃與進行之主要想法。

Bittern is the remains of brine after solar salt is produced. Except mainly containing 160 -200 g/L of NaCl, it consists of plenty of magnesium and potassium compounds (MgCl_2 70-90 g/L, MgSO_4 50-70 g/L, and KCl 10-20 g/L) and substantial amounts of rare elements. The Taiwan Salt Works (TSW) produces more than 50,000 metric tons of bittern annually. Domestic similar concentration remains of sea water which can be considered as a brine or bittern will be obtained from Tonghsiau Plant, TSW and Penhu Desalination Plant and other coming desalination plants which will be built in the future. In this study, a three-step systematic utilization of bittern is proposed, based on the research performed by TSW during the past few years. Emphasis is placed upon the utilization philosophy and some fundamental sciences and technologies employed.
