本“规程”包括操作工艺、去离子水、注射用去离子水质量控制指标与检验方法。一、操作工艺(一)工艺流程1.原水→过滤→阳离子交换树脂床→阴离子交换树脂床→混合树脂床→合格去离子水。2.原水→过滤→阳离子交换树脂床→阴离子交换树脂床→阳离子交换树脂床→阴离子交换树脂床→混合树脂床→合格去离子水(有条件的单位可加超滤膜装置)。(二)操作方法及说明1.原水质量要求[性状]本品为无色澄明液体。[检查]色度和浊度取本品50ml,置纳氏比色管中,在白色和黑色背景上,自上方观察,应为无色澄明。嗅气取本品100ml,置250ml 磨口锥形瓶中,
The “procedure ” includes the operation process, deionized water, injection of deionized water quality control indicators and test methods. First, the operation process (A) process 1. Raw water → filtration → cation exchange resin bed → anion exchange resin bed → mixed resin bed → qualified deionized water. 2. Raw water → filtration → cation exchange resin bed → anion exchange resin bed → cation exchange resin bed → anion exchange resin bed → mixed resin bed → qualified deionized water (conditional units can add ultrafiltration membrane device). (B) operating methods and instructions 1. Raw water quality requirements [Character] This product is colorless and clear liquid. [Check] Color and turbidity to take this product 50ml, home Nessler tube, on the white and black background, from the top of the observation, should be colorless and clear. Olfactive take this product 100ml, set 250ml mill mouth Erlenmeyer flask,
