Ngophuhliso olukhawulezayo lwemizi-mveliso kunye nokufudukela kwabantu ezidolophini, amanzi amdaka agxininiswe kakhulu abe yingxaki enkulu yokusingqongileyo. Amanzi amdaka agxininiswe kakhulu akaqulathanga kuphela isixa esikhulu sezinto eziphilayo, izinto ezingaphiliyo, isinyithi esinzima kunye nezinye izinto eziyingozi, kodwa nokugxininiswa kwayo kukude ngaphaya koyilo kunye nomthamo wonyango lwezibonelelo eziqhelekileyo zokucoca amanzi amdaka. Ke ngoko, ukuxinana okuphezulu konyango lwamanzi amdaka kunye nokukhutshwa okusemgangathweni kubaluleke kakhulu.
1. Inkcazo kunye neempawu zamanzi amdaka agxininiswe kakhulu Uxinzelelo oluphezulu lwamanzi amdaka, ludla ngokubhekisa kumanzi amdaka aqulathe ukuxinana okuphezulu kwezinto eziphilayo, isinyithi esinzima, izinto eziyityhefu neziyingozi kunye nezinye izinto ezingcolisayo. Isiqulatho esingcolisayo kumanzi amdaka uwadlula kude amanzi amdaka ngokubanzi, kwaye kunzima ukuwaphatha. Isenokuba neentlobo ngeentlobo zezinto ezingcolisayo, ezifana ne-organic matter, isinyithi esinzima, izinto ezisasazwa ngemitha, njl. njl. Ezinye izinto ezingcolisa umzimba zinokuba neziphumo ezithintelayo kwi-microorganisms kwaye zichaphazele isiphumo sonyango lwebhayoloji, ekunzima ukuyisusa ngeendlela eziqhelekileyo zonyango lwebhayoloji.
2. Imeko yokuveliswa kwamanzi amdaka agxininise kakhulu Ukuveliswa kweekhemikhali: amanzi amdaka avelisiweyo kwinkqubo yokuveliswa kweekhemikhali ahlala equlethe inani elikhulu lezinto eziphilayo, isinyithi esinzima kunye nezinye izinto ezingcolisayo. Umzi-mveliso wamachiza: Amanzi amdaka amayeza ahlala equlathe ukuxinana okuphezulu kwezinto eziphilayo, ii-antibiotics, njl., ekunzima ukunyanga. Idayi kunye noshishino lwamalaphu: Amanzi amdaka aveliswa ngala mashishini akholisa ukuba nezixa ezikhulu zezinto eziphilayo ezinokonakala kunye nechromaticity. I-Electroplating kunye ne-metallurgy: Amanzi angcolileyo aqulethe isinyithi esinzima kunye nezinto eziyityhefu ziveliswa ngexesha lokufakwa kwe-electroplating kunye ne-metallurgy.
3. Itekhnoloji engundoqo yezixhobo zokucoca amanzi amdaka aphezulu ekugxininiswe kuwo Izixhobo zokucoca amanzi amdaka, ngokuqhelekileyo ngokusebenzisa iindlela eziphathekayo okanye iikhemikhali zokususa amasuntswana amakhulu, izinto ezimisiweyo kumanzi amdaka, ukudala iimeko zokonyango olulandelayo. Iya kusebenzisa itekhnoloji ye-oxidation ephezulu efana ne-Fenton oxidation, i-oxidation ye-ozone, ngokuveliswa kwe-oxidant eyomeleleyo ukuguqula izinto eziphilayo ezichasayo zibe zizinto ezonakaliswa lula. Sebenzisa isenzo semetabolism ye-microorganisms ukususa izinto eziphilayo kumanzi amdaka. Kumanzi amdaka agxininise kakhulu, iinkqubo ezidibeneyo ze-anaerobic kunye ne-aerobic zingamkelwa ukuphucula umphumo wonyango. Izinto ze-tic kumanzi amdaka zinokususwa ngeendlela zenyama ngokusebenzisa itekhnoloji yokwahlula inwebu efana ne-ultrafiltration kunye ne-osmosis ebuyela umva. Ngokusebenzisa imvula yeekhemikhali, utshintshiselwano lwe-ion, i-adsorption kunye nobunye ubuchwephesha bonyango lwentsimbi enzima, esetyenziselwa ukususa iiyoni zetsimbi enzima kumanzi amdaka. Ke ngoko, kwizixhobo zoxinzelelo oluphezulu lwelindle, kubaluleke kakhulu ukuqinisekisa ukuba amanzi amdaka afikelela kumgangatho, ukhethe ngokufanelekileyo inkqubo yonyango, ulawule ngokungqongqo inkqubo yonyango, ukomeleza ukunyangwa kwangaphambili, ukwandiswa kweeparamitha zokusebenza kunye nokufunyanwa rhoqo kunye novavanyo. Ukuba kukho iingxaki ezifunyenweyo, thabatha amanyathelo afanelekileyo okulungisa.
Ngenxa yobunjani bomgangatho wayo wamanzi, ukucocwa okuphezulu kokucocwa kwamanzi amdaka kuneemfuno zobugcisa ezingqongqo zezixhobo. Kufuneka ibe neteknoloji efanelekileyo yemveliso, amava eprojekthi, kunye nombono wokulungelelanisa amanyathelo kwiimeko zendawo ukuze kuqinisekiswe ukuba ukungcola kwezixhobo zokucocwa kwamanzi amdaka aphezulu kuhambelana nomgangatho. Ukhuseleko lokusingqongileyo Jiading ngumzi-mveliso ophezulu kushishino logutyulo lwelindle iminyaka elishumi, esekelwe kwiphondo Jiangsu, radiation kwilizwe lonke, ejongene phesheya, ineqela elingqongqo imveliso yolawulo lomgangatho wobuchwephesha.
