本文介绍了一种处理有机硅废水的新的工艺组合，即铁炭微电解---水解酸化---UASB---MBR联合处理法，第一步铁炭微电解很明显的改善了有机硅原水的可生化性，BOD/COD值可达0.52；进入水解酸化池后，部分大分子降解成小分子物质，可生化性进一步提高；随后进入UASB，在颗粒污泥的作用下，COD去除率达到81%；在曝气池中，设置MBR，进一步去除了COD，去除率为96%；最终出水能达标排放。%This paper introduces a new combination of processes in the treatment of organic silicon waste water, which is the united method of the iron-carbon microelectrolysis proces-hydrolytic acidification-UASB-MBR. In the first step, the iron-carbon microelectrolysis process significantly improved the biodegradability of the organic silion raw water, BOD/COD value can reach 0.52; In the hydrolytic acidification tank, parts of the large molecules are degraded into small molecular substances, the biodegradability was further improved. In the third step, the removal rate of COD reached 81%at the effect of the granular sludge. In the final step, the organic pollutants got futher removal in the addition of MBR, and the removal rate of COD can reach 96%. The final effluent was appropriate to the standard.
