污水深度处理技术及其联合使用

摘要

The four technologies which are generally used in advanced wastewater treatment,including high efficient precipitation technique,rotary filter,denitrification deep-bed filter and active sand filter were described and an ap-plication case of the combined use of two high efficient precipitation techniques were introduced. Practical applica-tions indicate that with the combination of the high efficient precipitation techniques,which are normally used as the primary process for advanced wastewater treatment,the effluent could meet the first-level A standard for sewage treatment plants.%介绍了目前污水深度处理较常使用的4种技术，包括高效沉淀技术、转盘滤池、反硝化深床滤池和活性砂过滤器，列举了两种高效沉淀工艺联合使用的实例。实践证明，高效沉淀技术通常被作为第一级深度处理工艺，将两种高效沉淀技术结合使用后，出水水质能完全满足污水处理厂出水一级A的出水标准。
