| 内容記述 | Industrial wastewaters containing high concentrations of organic substances and ammonia nitrogen, such as leather industry wastewater, are sometimes treated by an activated sludge process in a sewage treatment plant. Such wastewaters tend to raise COD and color in the effluent of an activated sludge process. Refractory organic substance and nitrite build-up are the main causes of COD. It is difficult to reduce COD and color efficiently by the conventional activated sludge process. We studied a two-stage biological process combined an activated sludge process and a fixed-bed reactor to treat leather industry wastewater efficiently. And the use of ozone was studied to reduce COD and color. A two-stage biological process could promote nitrification reaction producing nitrate. COD originated from nitrite build-up was not observed. However, the two-stage biological process could not remove color. Ozone could reduce both COD and color in the effluent of an activated sludge process. However, nitrite build-up worsened the efficiency of ozone oxidation. In view of the economical point, it is important to prevent nitrite build-up in a biological process. |
