摘要

为研究污水处理厂厌氧氨氧化(Anammox)工艺可行性，在实际生活污水处理厂中进行厌氧氨氧化工艺的小试实验.向污水厂A/O除磷工艺出水中投加亚硝酸盐作为基质，启动厌氧氨氧化滤柱.反应器启动成功后，进水改为A/O除磷和亚硝化工艺处理后的生活污水，观察厌氧氨氧化工艺实际工程应用的效果.结果表明，第106~144天，进水温度为15~20 ℃，最大出水氨氮和总氮质量浓度为4.1和13.4 mg/L，出水氮素满足国家一级A排放标准；第168~204天，反应器运行进入冬季，进水温度为12~15 ℃，采用延长水力停留时间的方法实现污水处理达标；第222~240天时，水温降低到10~12 ℃，在进水投加125 mg/L碳酸氢钠，总氮去除负荷提高了40%，最大出水氨氮和总氮质量浓度为1.4和13.6 mg/L，冬季出水氮素达标.在整个过程中滤柱生物膜厚度持续增加，最终达113 μm，单位MLSS污泥厌氧氨氧化负荷大于5 kg/(kg·d)，厌氧氨氧化工艺在市政污水处理厂高效稳定运行.

Abstract

In order to study the feasibility of anaerobic ammonia oxidation(Anammox) process in Waste Water Treatment Plant(WWTP)

lab-scale Anammox reactor was employed in municipal WWTP. NaNO2 was added into the sewage effluent treated by A/O process in WWTP to serve as substance to start up Anammox filter reactor. In order to investigate the performance of Anammox process in engineering application

sewage effluent treated by A/O and nitrification process was served as inflow after the successful start-up of reactor. From the 106th to the 144th day

the maximal ammonia and total nitrogen concentrations in effluent were 4.1 and 13.4 mg/L with water temperature vary from 15 to 20 ℃ and the nitrogen concentration in effluent fitted the national 1A discharge standard of pollutants for municipal wastewater treatment plant. From the 168th to the 204th day

the reactor was running in the winter. When water temperature varied from 12 to 15 ℃

nitrogen concentration in effluent fitted the standard with the strategy of prolonging HRT. From the 222th to the 240th day

when the water temperature reduced to 10-12 ℃

NaHCO3 was added in inflow at a concentration of 125 mg/L. Nitrogen removal rate increasd 40 percents and the ammonia and total nitrogen in effluent was 1.4 and 13.6 mg/L. Nitrogen concentration in effluent reached the national 1A discharge standard of pollutants for municipal wastewater treatment plant in winter. The thickness of biomembrane increased continuely in the whole process of filter column and finally reached 113 μm. Ammonia anaerobic oxidation loading rate was greater than 5 kg/(kgMLSS·d) and Anammox process operated efficiently and stably.
