    • PURPOSE: Provided are method and apparatus for biologically decomposing wastewater containing organic sulfur compounds such as dimetyl sulfoxide(DMSO), which is generally introduced as release agents and cleaning agents in the field of the electronic industry. CONSTITUTION: Wastewater containing DMSO discharged from a factory or any other facilities is introduced into the apparatus body(1) through an inlet region(4). The wastewater introduced into the apparatus body(1) flows through the fluidized bed(3), then reaches the fixed bed(2), and then is discharged to the outside as treated water through the fixed bed. In this arrangement, the fixed bed is disposed under the fluidized bed(3) so that microorganisms released from the flowing carriers are captured by the fixed bed, thereby reducing suspended matters contained in the treated water. The flowing carriers continuously flow within the fluidized bed by the movement of the wastewater. This continuous flow enhances a contact efficiency of oxygen and the wastewater, enabling rapid increase of microorganisms, and enhances the attachment of microorganisms on the surfaces of the flowing carriers. Excessive microorganisms released from the flowing carriers are continuously fed to the fixed bed. As a result, the amount of microorganisms held by the fixed carriers is increased, so that the treatment capability per unit volume possessed by the entire apparatus is improved.
    • 目的:提供生物分解含有有机硫化合物如二甲基亚砜(DMSO)的废水的方法和装置,其通常作为电子工业领域的脱模剂和清洁剂引入。 构成:从工厂或任何其他设施排出的含有DMSO的废水通过入口区域(4)引入装置主体(1)。 引入装置主体(1)的废水流过流化床(3),然后到达固定床(2),然后通过固定床作为处理水排放到外部。 在这种布置中,固定床设置在流化床(3)下方,使得从流动载体释放的微生物被固定床捕获,从而减少处理水中所含的悬浮物质。 流动载体通过废水的运动在流化床内连续流动。 这种连续流动提高了氧气和废水的接触效率,能够快速增加微生物,并增强微生物在流动载体表面上的附着。 从流动载体释放出的过量微生物被连续送入固定床。 结果,由固定载体保持的微生物的量增加,从而提高了整个装置所具有的每单位体积的处理能力。
