利用多级水处理制备高纯度的注射用水,目前被医院制剂室广泛采用。使用该套设备制备蒸馏水,较老式塔式蒸馏器具有节能、蒸馏水纯度高等优点。我院结合自身特点,引进该套设备,在近5年的使用过程中,对于制水过程中的注意环节及针对各类问题的处理,积累一些经验,现报道如下。1　设 The use of multi-stage water treatment for the preparation of high-purity water for injection is currently widely used in hospital preparation rooms. The use of the device for the preparation of distilled water, compared with the old tower distiller has the advantages of energy saving, high purity of distilled water. In line with its own characteristics, the Institute has introduced this set of equipment. In the course of the past five years, it has accumulated experience for the attention link in the water production process and for the treatment of various problems. The report is as follows. 1 set
