摘要
随着膜组件使用年限的增加,膜逐渐出现老化,微生物污染也成为NF/RO系统运行过程中出现较频繁的问题之一,严重影响着膜系统的产水性能和使用寿命。选取长沙生活垃圾渗滤液处理厂反渗透/纳滤处理系统为分析对象,开展在线投加专用TJ Steri 600型非氧化性杀菌剂试验。结果表明,膜系统运行开始时在线连续添加TJ Steri 600型杀菌剂,能有效控制膜运行压力的上升并防止膜产水通量下降,同时可有效抑制微生物增长,且对电导率无显著影响;NF/RO膜运行压力较高的膜系统添加TJ Steri 600型杀菌剂后,膜运行压力稳定,上涨趋势不明显,大大减少膜元件化学清洗次数。
With increase of service life of membrane module,the membrane appears aging,and microbial contamination has become one of theproblems frequently appear in the NF/RO system running process,which seriously affects the water performance and service life of the membranesystem. The NF/RO treatment system of the life landfill leachate treatment plant in Changsha was selected as the analysis object,and the experiment ofonline application of TJ Steri 600 non-oxidizing fungicide was conducted. The results showed that when online continuous adding TJ Steri 600 non-oxidizing fungicide at the start of membrane system operation,it could effectively control the operation of membrane pressure rise and preventmembrane water production rate decline. At the same time,it could effectively inhibit the growth of microorganism,and without significant effect on theconductivity. After adding TJ Steri 600 fungicide to the membrane system with high pressure of NF/RO membrane,the membrane operation pressurewas stable,the rise trend was not obvious,and the frequency of chemical cleaning of membrane components was greatly reduced.
