进水方式对填料/CASS工艺处理酒精废水效果的影响

摘要

采用填料/CASS复合工艺处理玉米酒精废水,考察了全程进水、2h曝气进水、瞬时进水3种进水方式对污染物去除效果的影响.研究结果表明:不同进水方式对污染物的去除效果有不同影响,瞬时进水最好,2h曝气进水次之,全程进水最差.缩短进水时间可以保证反应器内反应以推流式进行,提高反应速率,能够有效去除污染物.%Corn alcohol wastewater has been treated by the combined process of filler and CASS.The effects of three water feeding modes:continuous all way through,2 h aeration and instantaneous,on the pollutant removing efficiency are investigated.The experimental results show that different water feeding modes have different effects on pollutant removing efficiency.Instantaneous feeding mode is the best,2 h aeration feeding mode the second good and the worst is the continuous feeding mode.Shorten the feeding time can assure the reaction flowing in the reactor,increase the reaction speed,and remove the pollutants effectively.
