摘要
应用纳米催化氧化技术对城市污水处理厂尾水进行末端脱氮增氧深度处理,通过试验确定了达到脱除氨氮要求下的最佳运行参数(最佳能耗、最佳停留时间等)以及万吨处理能力的设备设计参数,处理后出水的氨氮可稳定达到《地表水环境质量标准》(GB 3838—2002)Ⅴ类标准的要求。纳米催化氧化技术与传统生物脱氮相比具有技术先进、面积小、投资省、运行费用低等优点,是一种颠覆性的脱氮技术,具有广阔的应用前景。
Nano-catalytic oxidation technology was applied to the terminal denitrification and oxygenation of the tail water of the urban sewage treatment plant.The optimal operating parameters(optimal energy consumption,optimal residence time,etc.)under the requirements of ammonium removal are determined through the experiments.The design parameters were confirmed as well for the equipment which has a treatment capacity of 10000 tons wastewater.In addition,the ammonia nitrogen can stably meet the requirements of the“Surface Water Environmental Quality Standard”(GB 3838—2002)ClassⅤstandard.Compared with the traditional biological denitrification,nano-catalytic oxidation technology has the advantages of advanced technology,small area,low investment and low operating cost.It is a subversive denitrification technology with broad application prospects.
