一、引言 地层除铁是一项全新的地下水除铁工艺,在国外已得到迅速发展。近年来,我国也相继进行了试验研究和生产实践。但从国内外的资料报道来看,绝大多数是采用充氧回灌地层除铁法。唯有苏联在使用此法的基础上,开展了采用投加H_2O_2于地层中进行地下水除铁的试验研究。鉴于资料报道过简,我们曾就此法的可行性作了初步的论证。在此基础上又做了进一步的试验室试验,得出了生产试验所需的有关参数值。同时还对此法的除铁机理及其经济效益作了进一步的探讨和分析。
I. INTRODUCTION Formation removal of iron is a new groundwater iron removal process that has been rapidly developed abroad. In recent years, China has also carried out experimental research and production practices. However, according to domestic and foreign data reports, the vast majority use iron-removal methods to recharge the earth. Only on the basis of the use of this method, the Soviet Union carried out experimental studies on the removal of iron from groundwater by adding H 2 O 2 to the formation. In view of the fact that the information is too brief, we have made a preliminary argument on the feasibility of this law. On this basis, a further laboratory test was conducted and the relevant parameter values required for the production test were obtained. At the same time, the iron removal mechanism and economic benefits of this method were further discussed and analyzed.
