- 摘要：随着工艺设备、自动化控制技术的快速发展,SBR工艺对设备稳定性和自动化控制技术水平的基本要求得到满足,SBR工艺在世界范围内得到广泛发展和应用并取得了巨大的成功.现今全世界绝大多数的SBR污水处理厂都实现了最简单的自动控制(定时开/关控制或PID控制),但定时自动控制存在很大的缺陷.很多研究者开始尝试利用各种控制技术建立SBR实时控制策略.本文回顾了目前SBR实时控制策略的最新研究进展和实际应用,并对各种实时控制策略的优缺点进行分类、归纳和总结.虽然实时控制策略在SBR工艺的优化控制和节能降耗方面具有明显的优势,但在实际应用过程中还是存在很多问题尚待解决.最后通过分析SBR实时控制策略普遍存在的不足和问题,指出今后SBR实时控制策略的发展方向和应用前景.
- Abstract：With the rapid development of treatment technologies,equipment and autocontrol techniques,the basic requirements of equipment stability and autocontrol level for sequencing batch reactor(SBR)processes have been achieved,and SBR processes have been widely applied and hugely successful.Most SBR wastewater treatment plants have realized basic autocontrol(on/off or PID control),however,fixed-time autocontrol has had evident shortcomings.Therefore,many researchers have focussed on the establishment of real-time control strategies for SBR reactors which are based on control technologies.In this paper,the latest research progress and practical application of real-time strategies for SBR processes are reviewed and the advantages and disadvantages of real-time control strategies are classified and summarized.Although the real-time control strategy for SBR processes has great superiority in aspects of optimal control and energy saving,there are many unsolved problems in practical application.By analyzing the problems existing in the application,the future development direction of real-time control strategy for SBR process is indicated.
