Njengowona mthombo wamanzi okusela ophambili kulo mmandla, ukhuseleko lomgangatho wamanzi wedama lunxibelelene ngokuthe ngqo nempilo yoluntu kunye nophuhliso oluzinzileyo lwendalo. Kwiminyaka yakutshanje, ngotshintsho kwimeko engqongileyo, indawo yokugcina amanzi iye yajongana nemiceli mngeni emininzi, kubandakanya i-eutrophication, imingcipheko eyandisiweyo yeentyantyambo ze-algal, kunye nemisebenzi ebuthathaka yendalo. Iindlela zemveli zokubeka iliso ezenziwa ngesandla zinengxaki yokusilela kwedatha, iindawo ezininzi ezingaboniyo, kunye namaxesha okuphendula kancinane, okubenza bangakwazi ukuhlangabezana neemfuno zexesha lokwenyani lesilumkiso kunye nolawulo oluchanekileyo. Iprojekthi ngokungxamisekileyo ifuna isisombululo esikrelekrele esikwaziyo ukwenza yonke imozulu, iparamitha ezininzi, ukubeka iliso ngokuchanekileyo ukubonelela ngenkxaso yedatha eqinileyo yokubuyiselwa kwezinto eziphilayo kunye nokuthintela ukuqhakaza kwe-algal.

Njengesiqithi esikwinqanaba lesizwe le-ecological, i-Shanghai's Chongming District's crisscrossing network yemilambo nemisinga yenza icandelo elingundoqo lesiseko sayo se-ikholoji. Ukufezekisa ulawulo olusulungekileyo, lwexesha langempela, kunye nolawulo oluhlakaniphile lomgangatho wamanzi aphezu komhlaba kunye nokubeka iliso ngokuchanekileyo imilinganiselo yomgangatho wamanzi aguquguqukayo, isisombululo esibanzi sokudibanisa izikhululo zokuhlola umgangatho wamanzi e-intanethi kunye ne-buoys yokuhlola umgangatho wamanzi iye yaziswa kumlambo kwiSithili saseChongming, ukuseka umgca oqinileyo wokukhusela ukujongwa kokusingqongileyo kwamanzi kunye nokulumkisa kwangaphambili.

Umgaqo wokusebenza we-Fourier transform infrared spectrometer kukuba umqadi wokukhanya ongena kwi-interferometer yahlulwe ibe zimbini: umqadi omnye ujongwa kwisibuko esishukumayo, kwaye omnye ubonakaliswa kwisipili esisisigxina. Imiqadi emibini ibonakaliswa yizibuko ezisisigxina kunye nezihambayo, ngokulandelanayo, kwaye emva koko zibuyele kwi-beam splitter.

Izikhukula yintlekele yendalo eqhelekileyo. Xa amanzi ezikhukula ethotha, ethwele izinto ezingcolisa umhlaba, njengentlenga engaphezulu, inkunkuma, ilindle lasekhaya, namanzi amdaka avela kwimizi-mveliso, akaneli nje ukushiya izitrato neendledlana zichithakele, kodwa imilambo, amachibi namadama ajamelene nengozi yokuwohloka, ebeka esichengeni ukhuseleko lwamanzi okusela, imekobume yendalo kunye nempilo yoluntu.

Ezi gesi ziyingozi zilandelayo zikho ikakhulu kwimveliso, uvavanyo, ugcino kunye nokuhlaziywa koshishino lweebhetri:

Ivenkile yokupeyinta isisombululo sokujongwa kwegesi eyityhefu yinkqubo eyilelwe ngokukodwa ukujonga ukuhlangana kweegesi eziyityhefu neziyingozi (ezifana nebenzene, toluene, xylene, kunye nevolatile organic compounds (VOCs)) kwiivenkile zepeyinti.
