SBR工艺实时控制策略研究进展

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.

Research progress on real-time control strategies for sequencing batch reactors

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 ...
