東北小村鎮(zhèn)地區(qū)地下水中鐵錳氨氮去除實(shí)驗(yàn)研究

本實(shí)驗(yàn)研究了東北小村鎮(zhèn)地區(qū)地下水中鐵、錳、氨氮的去除效果以及影響因素。實(shí)驗(yàn)采用人工制備的化合物吸附劑、活性炭等材料進(jìn)行水處理，結(jié)果表明，化合物吸附劑可有效去除地下水中鐵、錳離子，去除92、78%；而活性炭對(duì)氨氮的去除效果較為顯著，去除83。影響因素分析表明，pH素對(duì)去除效果有較大的影響。Thisexperimentstudiedtheremovalefficiencyofiron,manganeseandammonianitrogeninthegroundwaterofsmalltownsinNortheastChina,aswellastheinfluencingfactors.Artificiallypreparedcompoundsadsorbents,activatedcarbonandothermaterialswereusedforwatertreatment.Theresultsshowedthatthecompoundadsorbentcaneffectivelyremoveironandmanganeseionsingroundwater,andtheremovalrateswere92%and78%,respectively;whileactivatedcarbonhasasignificanteffectontheremovalofammonianitrogen,andtheremovalratecanreach83%.TheanalysisofinfluencingfactorsshowedthatfactorssuchaspHvalue,reactiontime,andadsorbentdosagehaveasignificanteffectontheremovalefficiency.Keywords:groundwater;iron;manganese;ammonianitrogen;compoundadsorbent;activatedcarbon50ml1h后采用過濾法除去吸附劑，測(cè)定濾液中的鐵、50ml地下水放入燒杯中，添加一定量的活性炭，攪拌4h后采用過濾法除去活性炭，測(cè)定濾液中的氨氮濃度。0.1g/L1h后鐵、錳的去除率分別達(dá)到了92%和78%。0.3g/L4h后氨氮的去除率可達(dá)到pHpHpH值均會(huì)降低去83%pH值、反應(yīng)時(shí)間和吸附劑用量等。楊卓陳紹華田靜靜活性炭吸附-氧化處理水中氨氮的試驗(yàn)研究[J].中國給水排水,2015,31(14):45-48.劉志文宋瑾楊青Cu-MnOxFe（Ⅲ）的吸附實(shí)驗(yàn)研究[J].中國城市水務(wù),2017,(6):33-36.高峰崔寶娟張振峰Na2C
