- 摘要:
- 总氮的稳定达标是很多污水处理厂出水水质控制的难点。目前主要根据人工经验对系统工艺参数进行调控来实现，如控制溶解氧、投加碳源等，但是这些方法比较粗放且反应滞后，已不能适应精细化管理的要求。通过对总氮及硝态氮、氨氮在各工段的数据关系进行分析，发现将缺氧区末端混合液的溶解性硝态氮、氨氮控制在一定范围内（硝态氮与氨氮之和<10 mg/L），出水总氮可以稳定达标（<10 mg/L），据此实现了出水总氮的前置调控。
- Abstract:
- The stable and up-to-standard discharge of total nitrogen is a challenge for effluent quality control in many wastewater treatment plants (WWTPs). Currently, it is mainly achieved through the regulation of system process parameters based on the experience of management personnel, e.g., controlling dissolved oxygen and adding carbon sources. However, these methods are relatively inaccurate and have delayed reactions, which no longer meet the requirements of refined management in WWTPs. By analyzing the data relationship between total nitrogen, nitrate nitrogen, and ammonia nitrogen contents in each treatment section, it is found that controlling the dissolved nitrate nitrogen and ammonia nitrogen contents in the mixed liquor at the end of the anoxic zone within a certain range (the sum of nitrate nitrogen and ammonia nitrogen contents less than 10 mg/L), then the total effluent nitrogen content can be stably discharged up to standard (less than 10 mg/L), i.e. achieving pre?regulation of total effluent nitrogen.
