镰刀菌在环境保护中的应用作者摘要:镰刀菌属于霉菌中的一种菌种,镰刀菌不仅在食品、医学、生物保护等领域中发挥着重要作用,更在环境保护中起着巨大的作用。
特别是镰刀菌在生物脱除氮氧化物,生物降解酚类化合物、氰化物,吸收、蓄积、降解多环芳烃等方面的作用机理,指出了其在环境保护中的重要作用和巨大的应用前景。
关键词:镰刀菌;生物处理;环境保护Abstract: Fusarium belonging to the mold of a species of Fusarium, not only in the food, medicine, biological protection plays an important role in environmental protection, it plays a great role. In particular the Fusarium in biological removal of nitrogen oxides,biodegradation of phenolic compounds, cyanides, absorption, accumulation, and degradation of polycyclic aromatic hydrocarbons and other aspects of the mechanism of action, pointed out its ' important role in environmental protection and great application prospect.随着经济的发展,环境污染及生态破坏越来越严重,严重威胁着人类及其他生物的生存和发展,特别是氮氧化物、氰化物、苯酚、多环芳烃等,因此,对这些污染物的降解、去除,已成为当务之急。
而传统的物理、化学方法,由于成本高、容易产生二次污染等弊端,其应用越来越受到限制。
异养硝化-好氧反硝化菌的脱氮性能研究进展翁梓航;吕红;周集体【摘要】异养硝化-好氧反硝化(HN-AD)技术可在好氧的情况下同步去除水中的COD与总氮,其脱氮产物大多为无温室效应的氮气,脱氮过程中酸碱中和.然而实际废水成分复杂且水量水质不稳定,这使HN-AD技术的应用受到了限制.近年来不少学者针对不同的环境限制因子对HN-AD菌脱氮能力的影响进行了探索.为此,综述了近几年HN-AD菌在不同环境限制因子影响下的研究进展.%Chemical oxygen demand and total nitrogen in wastewaters could be simultaneously removed from water by heterotrophic nitrification-aerobic denitrification (HN-AD)technology under aerobic conditions.The main denitrification product is mostly nitrogen gas which does not have greenhouse effect,and acid-base neutralization can also be achieved in the process of denitrification.However,the ingredients of actual wastewater are complicated,and the water quantity and water quality are not stable,which limits the application of HN-AD technology.In recently years,many researchers have probed into the influences of different environmental limit factors on the denitrification ability of HN-AD bacteria.Based on this,the research progress in HN-AD bacteria under the influences from different environmental limiting factors is summarized.【期刊名称】《工业水处理》【年(卷),期】2017(037)003【总页数】5页(P21-25)【关键词】异养硝化-好氧反硝化;生物脱氮;废水处理【作者】翁梓航;吕红;周集体【作者单位】大连理工大学工业生态与环境工程教育部重点实验室,辽宁大连116024;大连理工大学工业生态与环境工程教育部重点实验室,辽宁大连116024;大连理工大学工业生态与环境工程教育部重点实验室,辽宁大连116024【正文语种】中文【中图分类】X703;X172在过去的几十年里,城市污水与工业废水中去除氨氮最常用的方法是微生物的好氧自养硝化和厌氧异养反硝化联合处理〔1〕。
