反硝化脱氮除磷-侧流磷回收工艺效能

为了调查反硝化同步脱氮除磷-侧流磷回收新工艺的工艺效能,该试验在该工艺稳定运行条件下评价其污染物（化学需氧量、总氮、NH＋4-N和PO3-4-P）去除能力和磷回收能力。结果表明：当进水中化学需氧量、总氮、NH＋4-N和PO3-4-P的质量浓度为239.2-259.5、39.6-43.8、38.2-41.8和8.72-11.40 mg/L,出水中相应的质量浓度分别为15.2-21.6、8.5-9.6、3.6-4.7和0.31-0.49 mg/L,满足国家《城镇污水处理厂污染物排放标准》（GB18918-2002）一级A排放标准;COD主要在厌氧池被去除,NH＋4-N主要在好氧硝化池中去除;污水中...

Summary:为了调查反硝化同步脱氮除磷-侧流磷回收新工艺的工艺效能,该试验在该工艺稳定运行条件下评价其污染物（化学需氧量、总氮、NH＋4-N和PO3-4-P）去除能力和磷回收能力。结果表明：当进水中化学需氧量、总氮、NH＋4-N和PO3-4-P的质量浓度为239.2-259.5、39.6-43.8、38.2-41.8和8.72-11.40 mg/L,出水中相应的质量浓度分别为15.2-21.6、8.5-9.6、3.6-4.7和0.31-0.49 mg/L,满足国家《城镇污水处理厂污染物排放标准》（GB18918-2002）一级A排放标准;COD主要在厌氧池被去除,NH＋4-N主要在好氧硝化池中去除;污水中磷的去除主要由诱导结晶磷回收和生物除磷两部分组成;整个工艺中,磷去除效率为95.9%,其中诱导结晶磷去除率占总去除效率的71.5%,表明该工艺具有较大磷回收潜力。此外,后置曝气池可对出水中COD、NH＋4-N和PO3-4-P浓度起着把关作用,有助于提高出水水质。

Generally, it is unsuitable for treatment of domestic wastewater with a low C/N ratio by conventional wastewater treatment processes due to the lack of carbon source in sewage, probably leading to not meeting the A in first-grade sewage effluent discharge standard of GB18918-2002. For this, development of an economic and environmental friendly process for treating of domestic wastewater is urgent, which may provide a benefit for development of wastewater treatment technologies and enhancement of water environmental quality. Moreover, phosphorus is a non-renewable resource and the quantities of mineral phosphorus resources are rapidly decreasing in the world due to increase i
