The technology of infrared spectroscopy ( ir ) is introduced in brief and the applications of it in the food safety testing are reviewed , especially in differentiation of food variety and place of production , detection of poisonous and harmful materials and pesticide residues in food , and identification of food having false 摘要本文对红外光谱在食品安全检测中的应用进行综述，简要介绍红外光谱分析技术，并着重阐述其在食品种类和产地鉴别、食品中有毒有害成分检测及食品中农药残留检测和食品掺假鉴定等方面的应用。
Abstract : through analysis on the character and use of geothermal water , expatiate the mechanism of iron removal from geothermal water , adopt the iron removal and manganese removal technology of aeration full oxygen and savageness manganese grit osculate oxidation , and control the intention and time of inverse flush , these make the treated geothermal water reach the standard of iron and manganese chroma , moreover , it won ' t increase bad component or decrease good component it is a perfect iron removal and manganese removal technology that can save installation investment , need low operating cost and reduce the heat losing 文摘:通过对地热水的特点及其用途的分析，阐述了地热水除铁除锰机理，采用曝气充氧、天然锰砂接触氧化的除铁除锰工艺，并适当控制反冲洗强度和时间，使处理后地热水含铁、锰浓度达到标准，且不增加有害成分或减少有益成分.设备投资省、运行成本低，热损失小，是一种理想的地热水除铁工艺
