摘要
反硝化除磷能够实现以相同的基质同时脱氮和除磷,是国外废水生物处理研究的一个热点。为此讨论了缺氧池NO-3负荷、溶解氧和好氧池与缺氧池体积比、废水pH值、NO-3与基质共存和NO-2等因素对反硝化除磷的影响及其模拟情况,为反硝化除磷过程的模拟、试验研究和实际的应用提供了参考和依据。
In the denitrifying phosphorus removal process, simultaneous removal of nitrogen and phosphorus can be achieved by using the same substrate. In recent years, it has become a hot issue in study of biological wastewater treatment. Therefore discussion was made on the process modeling and key factors affecting denitrifying phosphorus removal such as nitrate load to anoxic reactors, dissolved oxygen, volumetric ratio of aerobic and anoxic reactors, pH value, coexistence of nitrate with substrate, and nitrite, etc., and thus providing basis for modeling, experimental study, and practical application of the denitrifying phosphorus removal process.
