寒冷地区污水处理厂A^(2)O工艺改良调试与运行效果

Improvement Commissioning and Operation Effect of A^(2)O Process in Wastewater Treatment Plant in Cold Area

为进一步提升寒冷地区A^(2)O污水处理工艺的运行效果,以位于寒冷地区的A污水处理厂为研究案例,研究1种具有多点进水、混合液多点回流特性,且适用于寒冷地区污水处理厂的改良型A^(2)O工艺,并从多个角度着手,确定该工艺的设计要点和运行技术参数等内容。从实际应用效果来看,该改良型A^(2)O工艺在寒冷条件下仍可取得较优的处理效果,可为后续相关工作提供参考。

In order to further improve the operation effect of A^(2)O wastewater treatment process in cold areas,wastewater treatment plant A located in cold area was taken as a case to study a kind of improved A^(2)O process with multi-point inlet and multi-point reflux characteristics of mixed liquid,which is suitable for wastewater treatment plants in cold areas,and the design key points and operation technical parameters of the process were determined from multiple perspectives.From the practical application effect,the improved A^(2)O process can still achieve better removal effect under cold conditions,which can provide reference for subsequent related work.
