改良型序批式活性污泥反应器系统及其应用

介绍改良型序批式活性污泥反应器(MSBR1)系统及其运行和特点,并对脱氮除磷机理进行分析。MSBR系统综合了 SBR技术和活性污泥法的优点,是对现有脱氮除磷技术A2/O、Bardenpho、Phoredox等工艺的总结和提高。该系统不需设初沉池和二沉池,能在恒水位条件下连续进水和出水,具有处理效率高、一体化和自动化程度高、造价和运行费用低、操作简便等一系列优点,是国内外一种先进的去除营养(BNR)工艺。

Modified Sequencing Batch Reactor System and Its Application

Modified sequencing batch reactor (MSBR) system is a newly developed technology combined sequencing batch reactor (SBR) with activated sludge system. MSBR system is summarized and enhanced the nitrogen and phosphorus removal technologies at present, including A~2/O, Bardenpho, Phoredox proceedings etc. The system has lots of advantages, such as continuous influent and effluent without primary tank and final clarifier, whole process with constant level, high treatment efficiency, intensity and automation, but low cost of construction and operation. MSBR system's characters and operation and its mechanism of nitrogen and phosphorus removal are presented in this paper. As a conclusion, MSBR is an advanced biological nutrient removal (BNR) technology nowadays.
