基于工业园区废水处理厂氨氮快速达标研究

Study on Rapid Achieving Standard of Ammonia Nitrogen in Wastewater Treatment Plant of Industrial Park

摘要: 以某工业园区污水处理厂(该园区生产药品、医用易耗品)为例，针对废水厂处理过程中氨氮、TN不能稳定达标现象，对该废水主体改良CASS工艺段进行调试、研究和分析。根据实际工程遇到的问题，从理论和实践上对工艺调试及污泥中硝化细菌的快速培养进行探索，最终实现了出水氨氮快速稳定达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准的目的。

Abstract: Taking an industrial wastewater treatment plant in an industrial district as an example, according to the phenomenon of ammonia nitrogen instability reaching the standard in the process of wastewater treatment plant, the important links of CASS improvement process of wastewater treatment were debugged, studied and analyzed. According to the actual engineering problems, rapid cultivation of nitrifying bacteria in process debugging and activated sludge, from theory and practice, was explored. Finally the ammonia nitrogen rapidly reached “urban sewage treatment plant pollutant discharge standard” ammonia (GB18918-2002)-A standard.
