Ngenxa yophuhliso olukhawulezileyo lwemizi-mveliso kunye nokukhula kwezixeko, amanzi amdaka anoxinzelelo olukhulu abe yingxaki enkulu yokusingqongileyo. Amanzi amdaka anoxinzelelo olukhulu awagcini nje ngokuba nenani elikhulu lezinto eziphilayo, izinto ezingaphiliyo, iintsimbi ezinzima kunye nezinye izinto eziyingozi, kwaye uxinzelelo lwawo ludlula kakhulu amandla oyilo lwesiqhelo.izibonelelo zonyango lwamanzi amdakaNgoko ke, unyango kunye nokukhupha amanzi amdaka axineneyo kubaluleke kakhulu.
1. Inkcazo kunye neempawu zamanzi amdaka axineneyo
Uxinzelelo oluphezulu lwamanzi amdaka, ludla ngokubhekisa kumanzi amdaka aqulethe uxinano oluphezulu lwezinto eziphilayo, iintsimbi ezinzima, izinto ezinobuthi nezinobungozi kunye nezinye izinto ezingcolisayo. Umxholo wongcoliso emanzini amdaka udlula kakhulu lowo wamanzi amdaka ngokubanzi kwaye kunzima ukuwunyanga. Usenokuba neentlobo ezininzi ezahlukeneyo zongcoliso, ezifana nezinto eziphilayo, iintsimbi ezinzima, kunye nezinto ezinemisebe. Ezinye zezinto ezingcolisayo zinokuba nefuthe lokuthintela iintsholongwane, zichaphazele isiphumo sonyango lwebhayoloji, kwaye kunzima ukuzisusa ngeendlela zonyango lwebhayoloji eziqhelekileyo.
2. Iimeko zokuveliswa kwamanzi amdaka axineneyo kakhulu
Ukuveliswa kweekhemikhali: Amanzi amdaka aveliswa ngexesha lokuveliswa kweekhemikhali adla ngokuba nezixa ezikhulu zezinto eziphilayo, iintsimbi ezinzima kunye nezinye izinto ezingcolisayo.
Ishishini leMithi: Amanzi amdaka amachiza adla ngokuba nezinga eliphezulu lezinto eziphilayo, amayeza okubulala iintsholongwane, njl.njl., kwaye kunzima ukuwanyanga.
Ishishini ledayi kunye nelendwangu: Amanzi amdaka aveliswa kwezi mveliso adla ngokuba nenani elikhulu lezinto eziphilayo kunye ne-chromaticity enzima ukuzonakalisa.
Ukufakelwa kwe-electroplating kunye ne-metallurgy: inkqubo yokufakelwa kwe-electroplating kunye ne-metallurgy iya kuvelisa amanzi amdaka aneentsimbi ezinzima kunye nezinto ezinobuthi.
3. Itekhnoloji ephambili yesityalo sokucocwa kwamanzi amdaka axineneyo
Uxinzelelo oluphezuluindawo yokucocwa kwamanzi amdaka, ngesiqhelo ngeendlela zomzimba okanye zeekhemikhali zokususa amasuntswana amakhulu emanzini amdaka, izinto eziqinileyo ezixhonyiweyo, njl.njl., ukudala iimeko zonyango olulandelayo. Kuya kuba ngokusebenzisa i-oxidation yeFenton, i-oxidation ye-ozone kunye nezinye iteknoloji ye-oxidation ephucukileyo, ngokuveliswa kwee-oxidants ezinamandla kuya kuba nzima ukonakalisa izinto eziphilayo zibe zizinto ezibola lula. I-metabolism yee-microorganisms isetyenziselwa ukususa izinto eziphilayo emanzini amdaka. Kumanzi amdaka axineneyo kakhulu, indibaniselwano yeenkqubo ezifana ne-anaerobic kunye ne-aerobic ingasetyenziselwa ukuphucula unyango. Izinto ezinyibilikisiweyo emanzini amdaka zinokususwa ngeendlela zomzimba ngokusebenzisa iindlela zokwahlula i-membrane ezifana ne-ultrafiltration kunye ne-reverse osmosis. Iiteknoloji zonyango lwe-heavy metal ezifana ne-chemical precipitation, i-ion exchange kunye ne-adsorption zisetyenziselwa ukususa ii-heavy metal ions emanzini amdaka.
Ngoko ke, ukuze kubekho uxinano olukhulu lwesityalo sokucocwa kwamanzi amdaka, ukuqinisekisa ukuba amanzi amdaka ayahlangabezana nomgangatho, ukhetho olufanelekileyo lwenkqubo yokucocwa, ulawulo olungqongqo lwenkqubo yokucocwa, ukuqinisa unyango lwangaphambi kokucocwa, ukwenza ngcono iiparameter zokusebenza kunye novavanyo oluqhelekileyo kunye novavanyo kubaluleke kakhulu, ukuba kufunyenwe iingxaki, thatha amanyathelo ngexesha elifanelekileyo ukuze ulungise.
Isityalo sokucocwa kwamanzi amdaka anomthamo ophezulu ngenxa yomgangatho wamanzi aso okhethekileyo, kuba izixhobo zinemfuno zobugcisa ezingqongqo, imfuneko yokuba netekhnoloji yemveliso elungileyo, amava eprojekthi, kunye nengcamango yeemeko zasekuhlaleni, ukuqinisekisa ukuba ubuninzi bamanzi amdaka buphezulu.izixhobo zokucoca amanzi amdakaukuhlangabezana nemigangatho yamanzi amdaka. I-Liding Environmental Protection ngumzi-mveliso omdala weminyaka elishumi kushishino lokucocwa kwamanzi amdaka, oseJiangsu, osasaza kulo lonke ilizwe, ujongene naphesheya, kunye neqela elingqongqo lokulawula umgangatho wetekhnoloji yemveliso.
