造纸废水生物脱硫技术研究

Study on Biological Desulfurization Technology of Papermaking Wastewater

目前,随着我国工业技术的不断进步和发展,造纸废水脱硫技术领域也取得了进步,比较常用的造纸废水脱硫技术包括物理处理法、化学处理法及回收利用法等,但每种方法都或多或少存在缺陷和不足,如投资成本高、脱硫技术不完善、空气质量检测不合格、部分硫化物处理过程中含硫气体溢出等,这些都是急需解决的问题。本文论述的造纸废水生物脱硫技术,不仅可以有效提高好氧生化处理效率,还可以极大地降低废水处理成本,且方法合理、效果显著,是造纸废水处理技术的首选。

At present,with the continuous progress and development of China’s industrial technology,the field of paper waste water desulfurization technology has also made progress,more commonly used paper making wastewater desulfurization technology including physical treatment,chemical treatment and recycling,but each method has more or less defects and deficiencies.For example,high investment cost,imperfect desulfurization technology,unqualified air quality detection,and sulfur-containing gas overflow in some sulfide treatment processes are all problems that need to be solved urgently.The paper discusses the paper wastewater biological desulfurization technology,not only can effectively improve the efficiency of aerobic biochemical treatment,but also can greatly reduce the cost of wastewater treatment,and the method is reasonable,the effect is remarkable,is the first choice of papermaking wastewater treatment technology.
