对接触稳定法改良的建议

IMPROVEMENT ON CONTACT STABILIZATION SYSTEM

用接触稳定法处理城市污水时,对溶解性有机物去除效果较差.本文介绍的一种改良接触稳定法,将原再生池改为传统曝气池,并改变剩余污泥排放点和污泥回流系统.通过和原吸附曝气池相互弥补、协同作用,提高了对溶解性有机物的去除效果.

Against the poor removal of dissolved organics in urban wastewater treatment by contact stabilization process, an improved variant process was developed by reformation of the formerly regenerator to conventional aeration tank, the outlet of surplus sludge and sludge recycling system. The efficiency to remove dissolved organics increased as a result of closed and cooperative effect with the absorption aeration tank.
