摘　　要：对培养嗜高浓度甲醛废水的活性污泥的净化性能进行了研究，研究中采用序批式活性污泥法（SBR）及脱氮除磷工艺（A2/O工艺）．考察了停留时间、溶解氧多少、进水的pH值和水温等对微生物净化高浓度甲醛废水的影响。实验结果表明，进水的pH值在7～9范围内，水温在10～30℃，停留时间控制在48小时，并根据进水浓度的变化选择合适的溶解氧，获得的活性污泥的净化性能最佳。In this article, we cultivate activated sludge which centrated formaldehyde wastewater. Sequencing bateh reactor research. We study Factors which have an influence on the can be used in the biodegradation of high con- （SBR） and （A2/O） processes are used in our biodegration of high concentrated formaldehyde wastewater such as residence time,PH.water temperature and so on. The experiment result shows best perfor- mance of activated sludge purification is under the situation that incoming water PH is between 7-9, water temperature is between 10 to 30 ℃, residence time is controlled at 48 hours, and select the appropriate dis- solved oxygen according to changes in influent concentration.
