摘要：

通过投加碳源的方法来强化水解—接触氧化组合工艺处理亚麻废水的能力，取得了较好的试验效果。在不加碳源时，COD_Cr的去除率仅为80.96%，出水COD_Cr高达795mg/L。但当投加微生物易吸收利用的碳源之后，COD_Cr的去除率均>90.1%，尤其是从两处向系统投加碳源时，COD_Cr去除率>93%。所补充的碳源不仅增强了微生物的活性和数量，同时也提高了微生物的协同代谢能力，最终提高了系统对COD_Cr的去除能力。

Abstract:

By means of adding carbon source, the capability of hydrolytic-contact oxidation combination treatment process is strengthened. It obtains good results. Without adding carbon source, the COD removal rate is only 80.96%, and the effluent COD is as high as 795mg/L. After adding carbon source which can absorb microbes easily, the COD removal rate is obviously improved, higher than 90.10%. The effluent COD removal rate exceeds 93.00%, especially when carbon source is added to the technology from 2 places. The carbon source supplied can not only increase the activity and amount of microbes, but also increase the capacity of coordination and metabolism of microbes.

Key words: flax wastewater, hydrolytic process, contact oxidation process
