摘　　要：针对传统生物脱氮除磷工艺存在的一些不足,即微生物的混合培养,泥龄,碳源和回流污泥中的硝酸盐问题,概要介绍了双循环两相生物处理(BICT)工艺,厌氧/缺氧和硝化(A2N)工艺,BCFS工艺,分段进水BNR工艺,厌氧-往复好氧组合式工艺等几种近年来针对这些问题提出的改进工艺,并从处理工艺的原理、流程和应用于实际工程尚需进一步研究的问题等方面对这些工艺进行了比较和评述。In view of the disadvantages of traditional biological nutrient removal process, i.e., problems existed in the mixed cultivation of microorganisms, sludge age, carbon source, and nitrate in returned sludge, some modified process appeared in recently years such as： BICT, A2N, BCFS, step feed BNR, anaerobic-reciprocal aerobic combined process and so on were briefly introduced. Meanwhile, the above processes were compared and observed from principle, flow, problems need to be further studied for application in engineering and some other aspects.
