style="font-size:16px;"><strong>貴州純化水設備，離子交換器的失效有以下控制方法</strong></span></span><br /> <br /> <div> <span style="font-family:宋體;"><span style="font-size:16px;">1.檢測和控制原理</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">強酸性陽樹脂對水中各種陽離子的吸附順序為：Fe3+>Al3+>Ca2+>Mg2+>Na+>H+.；由此可知，水中金屬離子Na+被吸附的能力是最弱的，所以當離子交換時樹脂層的各種離子吸附層逐漸下移，H+.最后被其他陽離子置換下來，當保護層穿透時，首先泄漏的是最下層的Na+；因此監督陽離子交換器失效是以漏鈉為標準的；其反應方程為（A代表金屬陽離子,R為樹脂基團）：</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">An++nRH=RnA+nH+</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">HCO3-+H+=H2O+CO2↑</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">強堿性陰樹脂對水中各種陰離子的吸附順序為：SO42->NO3->Cl->OH->HCO3->HSiO3-。由此可知，HSiO3-的吸附能力最弱，所以當離子交換時樹脂層的各種離子吸附層逐漸下移，OH-.則被其他陰離子置換下來，當保護層穿透時，首先泄漏的是最下層的HSiO3-；因此監督陰離子交換器失效是以漏硅為標準的；其反應方程為（B代表酸根陰離子，R為樹脂基團）：</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">Bm-+mROH=RmB+mOH-</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">2.控制點和控制方法</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">由于母管制系統包含了單元制系統,而且它具有能充分使用樹脂、提高交換器的出水能力、降低酸堿消耗等優點，我們在研究中主要討論以這種結構為基礎的離子交換除鹽水處理系統。</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">1）RO對各有機溶質的去除率大于NF膜。</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">2）不同有機溶質的去除率不相同，有的甚至相差很大（例如，RO和NF膜對乙酸的吸光度去除率分別為95.34％、81.45％，而對苯胺的吸光度去除率則分別為61.50％、46.82％）。</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">3.出水水質</span></span></div> <div> </div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">原水經一級復床除鹽后，電導率（25℃）低于10μS/cm，水中硅含量低于100μg/L。</span></span></div> <br
