摘　　要：通过实验室试验,研究了向厌氧反应器中投加微量金属元素对食品废水中污染物及色度去除效果的影响。结果发现,微量金属元素的投加,能改善废水的可生化性,废水的BOD5/COD值从进水的0.40升至厌氧出水的0.51,减轻了后续处理负荷,使废水的COD与色度的去除率提高。此工艺在实际废水处理工程中也收到了良好的运行效果。Based on the character of sweetened bean paste wastewater with high COD,high color,and the problem of return to high colority in the wastewater treatment engineering, a lab static treatment for the wastewater experimnent was carried using metal microetement under the condition of anaerobic acidification and aerobic biooxidation and the resuhs showed that metal microelement can increase the number of BOD5/COD from 0.4 to 0. 51, alleviate the burden of subsequent treatment,increase biodegradation efficiency of COD and color,and control the color return under the condition of oxygen to a certain extent. This craft has also achieved the good result in the actual waste water processing project.
