摘 要

由于树脂被越来越多地应用于热电厂水处理系统之中，树脂的污染程度也日趋严重。一般的处理工艺对于树脂的交换容量的恢复已经没有显著成效。本文通过研究达到国家报废标准的001×7型强酸性阳树脂和201×7型强碱性阴树脂的结构特点，以超声波对阴、阳离子树脂的复苏处理为研究对象，针对热电厂去离子水处理用树脂使用超声波复苏工艺及条件进行设计分析，对传统的离子树脂的清洗工艺和复苏工艺进行优化和讨论，本文的研究内容及结果如下：

1. 通过对超声波复苏工艺作出研究，分别考察不同超声波功率、超声处理时间下对树脂复苏的影响。针对超声波复苏处理后的树脂交换容量的变化进行对比分析，结果表明，超声波的功率是影响树脂复苏的主要因素之一，但是功率过高会对功能基团造成破坏，故应在安全范围内考虑复苏。
2. 通过研究在超声波基础上不同条件对阳树脂复苏的效果的影响，分别从复苏药剂和固液比等参数条件进行分析，研究结果表明，复苏阳树脂第一步使用4%盐酸溶液不能达到理想效果，故第二步针对阳树脂使用还原法即亚硫酸钠溶液作为还原剂复苏效果更佳。综合考虑复苏效果，在通过使用超声波进行复苏的前提条件下，再使用还原法对阳树脂进行处理。
3. 经过试验研究发现，在使用超声波进行复苏的基础上，复苏阴树脂第一步使用10%氯化钠溶液并不能达到理想要求，针对此情况采取op-10溶液作为第二步的复苏药剂。结果显示，第二步选取表面活性剂op-10溶液进行超声复苏，复苏的效果更优，复苏后阴树脂的交换容量和机械强度都达到了理想效果，实现了资源的回收与利用，可以为企业带来可观的经济效益。

ABSTRACT

With the wide application of ion-exchange resin in thermal power plant water treatment system, its pollution situation is becoming more and more complicated. Common recovery processes have been difficult to effectively eliminate iron and organic pollutants to restore the resin exchange capacity to a new level. This dissertation through studies meet the national standards of 001 × 7 strong acid cation resin and 201 × 7 strong basic anion resin structure characteristics, with ultrasonic recovery processing of anion and cation resin as the research object, antagonized water treatment with resin in the thermal power plant using ultrasonic recovery process and conditions for design and analysis, the cleaning process of the traditional ion resin and recovery process is optimized and discussed, in this dissertation, the research contents and results are as follows:

1. By studying the ultrasonic resuscitation process, the influence of different ultrasonic power and ultrasonic treatment time on resin resuscitation was investigated. According to the comparison and analysis of resin exchange capacity after ultrasonic resuscitation, the results show that ultrasonic power is one of the main factors affecting resin resuscitation.However, high power will damage functional groups, so recovery should be considered in the safe range.

(2) Through the research on the basis of ultrasonic, and the effects of different conditions on the cation resin recovery, respectively from the recovery potions and solid-liquid ratio and other parameters were analyzed, and the results show that the first step to recovery cation resin with 4% hydroelectric acid solution can't achieve the ideal effect, so the second step is to use the reduction method of sodium sulfite solution as the reducing agent for the recovery of the cation resin, considering the recovery effect, under the condition of recovery by using ultrasonic premise, using the reduction method to deal with cation resin.

(3) After experimental study, it was found that on the basis of ultrasonic resuscitation, 10% sodium chloride solution in the first step of resuscitation resin could not meet the ideal requirements. In view of this situation, op-10 was adopted as the second step of resuscitation agent. The results show that the second step is to select surfactant op-10 solution for ultrasonic resuscitation, and the effect of resuscitation is better. The exchange capacity and mechanical strength of the resin have reached the ideal effect after recovery, and the recovery and utilization of resources have been realized, which can bring considerable economic benefits to the enterprise.

1.1.1 课题研究背景

火力发电的应用技术越来越成熟，作为主要发电方式中的重要组成部分，火电厂只发电，不向外供热。热电厂既能向外供电，也能向外供热。为满足人们的日常生活需求，热电厂通常将发电后产生的热水经过再次加热后进行供暖，在电力生产的同时，通过利用汽轮机抽、排气来为用户供热。
