摘要
生物硝化是废水(尤其是工业废水)生物脱氮的关键和前提.作者在总结有关文献的基础上,结合自己的试验体会,论述了硝化细菌的生理特点及影响硝化细菌生长速率的主要因素,指出应根据原水水质特点采用合适硝化工艺,对于BOD/NH_3—N值较高的废水宜采用活性污泥法,反之宜采用生物膜法,并提出了设计硝化反应器应考虑的措施及启动和运行硝化反应器时应注意的问题.
Biological nitrification acts as a key preliminary to biological N removal of wastewater especially for industrial wastewater treatment. On the basis of bibliographic reference and experimental experience by the author self the physiological feature of nitrification bacteria and factors to effect their growth rate are discussed and it is emphasized that the nitrification process should be selected adequately in line with the characters of the raw wastewater. For wastewater with high BOD/NH3-N content the activated sludge process will be suitable otherwise the attached biofilm process better. Also some measures and problems meriting consideration in designing, starting and operating a nitrification reactor are proposed.
