UASB-AO工艺在污水处理厂提标改造中的应用

Application of UASB-A/O process to upgrading and reconstruction of wastewater treatment plant

某污水处理厂无法达到现行《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准,为此对污水处理系统进行了改造,新建UASB池,结合原有的A/O池组成UASB-A/O组合工艺。UASB池可以提高后续A/O池的脱氮除磷效果,处理水质达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。

The wastewater treatment plant is unable to meet the current standard of first A class of ＂Municipal Wastewater Treatment Plant discharge standards＂ （GB18918-2002）. Sewage treatment system has been reconstruction.UASB pool has been construction to combine with the intrinsic anaerobic pool and aerobic pool to UASB-A/O Process. UASB pool can improve the effect of nitrogen and phosphorus removal process for the following A/O pool.The effluent can meet the standard of first A class of ＂Municipal Wastewater Treatment Plant discharge standards＂（GB 18918-2002）.
