  A method for adsorbing and recovering a fluorine-containing emulsifier at a high recovery from coagulation waste water of a fluoropolymer, is presented. An inorganic acid is added to coagulation waste water of a fluoropolymer containing a fluorine-containing emulsifier, to adjust the pH of the waste water to a level of at least 1 and less than 6, then a metal chloride having a solubility of at least 5 mass% in water at 25°C, or a hydrate of the metal chloride, is added to the waste water, to coagulate and remove a solid content and/or a substance convertible to a solid content, contained in the waste water, and then the waste water is contacted to a weakly basic anion exchange resin.

  本发明提出了一种从含氟聚合物的混凝废水中以高回收率吸附和回收含氟乳化剂的方法。在含有含氟乳化剂的含氟聚合物的混凝废水中加入一种无机酸，将废水的 pH 值调节到至少为 1 但小于 6 的水平，然后在 25°C 的水中加入一种溶解度至少为 5 质量％的金属氯化物或金属氯化物的水合物、或该金属氯化物的水合物，使废水中含有的固体成分和/或可转化为固体成分的物质凝结并去除，然后将废水与弱碱性阴离子交换树脂接触。

  An aqueous solution containing a fluorine-containing emulsifier in a low concentration of at least 1 ppm by mass and at most 1% by mass (e.g., coagulation waste water after an emulsion polymerization of a fluoropolymer and/or an aqueous solution obtained by washing with an aqueous solution a waste gas from a drying process and/or a heat treating process of the fluoropolymer) is subjected to vacuum concentration under a pressure of at most 100 kPa and a temperature of the aqueous solution of at most 100°C by means of a heating tube surface evaporation type concentrator equipped with a heat pump or the like, and the fluorine-containing emulsifier is recovered from a highly concentrated aqueous solution containing the fluorine-containing emulsifier in a higher concentration of at least 5% by mass. According to the present method, the fluorine-containing emulsifier can be recovered with a high yield from a low-concentration liquid such as coagulation waste water of a fluoropolymer.

  含有含氟乳化剂的低浓度水溶液，其质量浓度至少为 1 ppm，最多不超过 1%（例如：含氟聚合物乳液聚合后的凝结废水和/或用水溶液洗涤含氟聚合物干燥过程和/或热处理过程中产生的废气而得到的水溶液）、含氟聚合物乳液聚合后的凝结废水和/或用水溶液洗涤含氟聚合物干燥工序和/或热处理工序产生的废气后得到的水溶液），在压力不超过 100 kPa 和水溶液温度不超过 100°C 的条件下，通过配备热泵或类似装置的加热管表面蒸发型浓缩器进行真空浓缩、从高浓度水溶液中回收含氟乳化剂，高浓度含氟乳化剂的质量浓度至少为 5%。根据本方法，可从低浓度液体（如含氟聚合物的凝结废水）中高产率地回收含氟乳化剂。
