matrix）內(nèi)藏氯化鈉，在硬水軟化的過程中，鈉離子會逐漸被使用耗盡，則交換樹脂的軟化效果也會逐漸降低，這時需要作還原（regeneration）的工作，也就是每隔固定時間加入特定濃度的鹽水，一般是10%，其反應(yīng)方式如下：Ca-EX2+2Na+ （濃鹽水）→ 2Na-EX+Ca2+Mg-EX2+2Na+ （濃鹽水）→ 2Na-EX+Mg2+</p><p> 化工廢水主要特征分析

（3）有毒有害物質(zhì)多，有機物濃度高、含鹽量高、色度高、難降解化合物含量高、生物難降解物質(zhì)多，可生化性差、治理難度大。精細化工廢水中有許多有機污染物對微生物是有毒有害的，如鹵素化合物、硝基化合物、具有殺菌作用的分散劑或表面活性劑等；水處理是指通過一系列水處理設(shè)備將被污染的工業(yè)廢水或河水進行凈化處理。</p><div
