Amanzi amdaka emizi-mveliso ngamanzi amdaka, indle kunye nolwelo olungcolileyo oluveliswa kwinkqubo yemveliso yemizi-mveliso, ngokuqhelekileyo luqulathe izinto zokuvelisa mizi-mveliso, iimveliso eziphumayo kunye nongcoliseko oluveliswa kwinkqubo yemveliso. Unyango lwamanzi amdaka emizi-mveliso lubhekisa kwinkqubo yokuphatha ngokufanelekileyo amanzi asetyenziswa kwinkqubo yemveliso yemizi-mveliso yokuvelisa okanye yokukhupha amanzi kumzi-mveliso, anokuphatha ngokufanelekileyo amanzi amdaka aveliswa kwintsimi yemizi-mveliso kwaye anciphise ungcoliseko lokusingqongileyo. Njengenye yeendlela ezibalulekileyo zokulawula okusingqongileyo, unyango lwamanzi amdaka emizi-mveliso luneempawu zonyango olungenabungozi, oluncitshisiweyo nolunxulumene nabantu, kwaye lusetyenziswa kakhulu kumayeza, ukushicilela kunye nokudaya, iikhemikhali, intsimbi kunye nezinye iindawo zoshishino. Unyango lwamanzi amdaka emizi-mveliso luthatha amanyathelo ahlukeneyo onyango ngokwendlela yongcoliseko kumanzi amdaka. Ngokwenkqubo yalo yonyango, lunokuba
Yahlulwe yaba yindlela yonyango lomzimba, indlela yonyango lwamakhemikhali, indlela yonyango lwefiziksi kunye nendlela yonyango lwebhayoloji. Phakathi kwazo, i-activated sludge kwindlela yonyango lwebhayoloji. Le ndlela isebenza kakuhle kakhulu ekuguquleni iikhemikhali kwaye inefuthe elihle ekuphatheni ukungcola emanzini amdaka emizi-mveliso yendalo. Okwangoku yeyona nkqubo yonyango lwamanzi amdaka emizi-mveliso esetyenziswa kakhulu.
Ukwaziswa kwemigaqo-nkqubo yokukhokela uphuhliso lokonga amandla kunye nokukhuselwa kwendalo kwishishini lokunyanga amanzi amdaka kwimizi-mveliso Njengenye yeendlela ezibalulekileyo zokulawula indalo, unyango lwamanzi amdaka kwimizi-mveliso ludlale indima ebalulekileyo kwimveliso yemizi-mveliso. Ngo-Okthobha ka-2010, iBhunga leSizwe laseTshayina lacebisa kwi-"Isigqibo sokuKhawulezisa ukuLinywa kunye noPhuhliso lweeShishini eziPhumayo eziCwangcisiweyo" ukuba ukugcinwa kwamandla kunye nokukhuselwa kwendalo kufuneka kuthathwe njengenye yemizi-mveliso esixhenxe ephuhlisayo enobuchule, igxile ekukhuthazeni izixhobo zobugcisa kunye neemveliso ezisebenza kakuhle kakhulu, kunye nokufezekisa ubuchwepheshe obuphambili kwiindawo eziphambili. Impumelelo iya kuqhuba ukuphuculwa kwenqanaba lilonke lokusebenza kakuhle kwamandla. Ngo-Epreli ka-2015, iBhunga leSizwe laseTshayina lakhupha iSicwangciso sokuSebenza sokuThintela nokuLawula ukuNgcoliswa kwamanzi ("Amanzi alishumi"), olu luphawu lokuqala lolawulo lweTshayina kunyango lwamanzi kwimizi-mveliso. Izicwangciso zonyango ezikhethekileyo kwimizi-mveliso elishumi ephambili efana neentsimbi ezingenayo i-ferrous, ukuprinta kunye nokudaya, ukucola, kunye nokuveliswa kwe-API ziyaphunyezwa, kwaye utshintsho olucocekileyo luyaphunyezwa ukufezekisa injongo yokulungisa ungcoliseko lwamanzi. Ukongeza, "iMithetho yeManzi elishumi" ikwabeke phambili amanyathelo anamandla angama-238 okulawula ungcoliseko kwiindawo zemizi-mveliso. Kuyabonakala ukuba ngelixa igxile ekunciphiseni inani lilonke lokukhupha ungcoliseko, iTshayina inika ingqalelo engakumbi ekuphuculeni umgangatho wokusingqongileyo kwamanzi kunye nokuthintela nokulawula iingozi zokusingqongileyo. Ngo-Okthobha ka-2017, kwingxelo ye-19th National Congress yeQela lamaKomanisi laseTshayina, kwakufuneka kuphuculwe imigangatho yokukhupha ungcoliseko, kuqiniswe uxanduva lwabangcolisi, kwaye kuphuculwe uvavanyo lwetyala lokusingqongileyo, ukutyhilwa kolwazi oluyimfuneko, isohlwayo esiqatha kunye nezinye iinkqubo. kuya kudlala indima enkulu yokukhokela. Kwelinye icala, kumthetho werhafu yokukhuselwa kokusingqongileyo, urhulumente waseTshayina ukwazise imigaqo-nkqubo efanelekileyo. NgoDisemba ka-2017, iBhunga leSizwe laseTshayina lapapasha iMithetho yokuphunyezwa koMthetho weRhafu yoKhuseleko lokusingqongileyo weRiphabliki yabantu baseTshayina, efuna abahlawuli berhafu ukuba bakhuphe ungcoliseko lwamanzi olunexabiso eliphantsi kune-30.0% yomgangatho wokukhupha ungcoliseko ochazwe ngoorhulumente bakarhulumente kunye noomasipala, kunye nokunciphisa i-75.0% % irhafu yokukhuselwa kokusingqongileyo; Ukuba uxinano lwezinto ezingcolisayo lungaphantsi kwe-50.0% yomgangatho wokukhupha izinto ezingcolisayo ochazwe ngoorhulumente bakarhulumente nabasekhaya, irhafu yokukhusela indalo iya kuhlawuliswa ngesantya esincitshisiweyo se-50.0%. Emva kokuphunyezwa kwalo mgaqo-nkqubo, ukuqokelelwa kweentlawulo zelindle kuye kwapheliswa, nto leyo ebaluleke kakhulu ekukhuseleni nasekuphuculeni indalo, ekunciphiseni ukukhutshwa kwezinto ezingcolisayo, kunye nokukhuthaza ukwakhiwa kwempucuko yendalo.
Umthombo: Iboniswe yiSullivan Institute Ubuchwepheshe bokucoca amanzi kunye nendlela yenkqubo iya kubonisa indlela yophuhliso eyahlukeneyo. Phantsi kwemigaqo-nkqubo yesizwe efanelekileyo, ubuchule bokuvelisa ubuchwepheshe bokucoca amanzi amdaka emizi-mveliso yaseTshayina buphuculwe kakhulu, nto leyo eye yakhuthaza ukuphuculwa kwenqanaba lokucoca amanzi amdaka emizi-mveliso yaseTshayina. Ngenxa yobunzima bokungcola kwamanzi emizi-mveliso,
Kunzima ukuba iteknoloji enye ifikelele kwisiphumo esifunekayo. Ke ngoko, amashishini onyango lwamanzi amdaka kwimizi-mveliso kufuneka enze uphando oludibeneyo ngeendlela ezinqamlezileyo, ezihambelanayo, nezisebenzisanayo ngokusebenzisa ubuchwepheshe obupheleleyo bonyango lwamanzi, njengokudibanisa iikhemikhali-ngokomzimba. Iindlela zonyango, iindlela zonyango oludibeneyo lweekhemikhali-ngokwebhayoloji, njl.njl., ukuze kufezekiswe iinjongo zokusebenza kakuhle, ukusetyenziswa okuphantsi kunye nokukhuselwa kokusingqongileyo. Kwelinye icala, kwinkqubo yamanzi okupholisa ejikelezayo enenxalenye enkulu yokusetyenziswa kwamanzi, ifomula yekhompawundi esekwe kwisikali isetyenziswa kakhulu, kodwa ngenxa yokuba i-phosphorus-based corrosion kunye ne-scale inhibitor kule fomula inokusebenza njengesondlo seebhaktheriya kunye ne-algae emanzini, ibangele ungcoliseko lwamanzi I-Eutrophication kunye nongcoliseko lwamanzi. Ke ngoko, ngokuphuculwa kwetekhnoloji yonyango lwamanzi amdaka kwimizi-mveliso yaseTshayina, uphuhliso lweekhemikhali zonyango lwamanzi ezine-phosphorus ephantsi okanye ezingezizo i-phosphorus, ezingezizo i-nitrogen, ezinokubola, ezisebenza ngeendlela ezininzi nezinobuhlobo nokusingqongileyo ziya kuba yindlela ephambili yophando lonyango lwamanzi amdaka kwimizi-mveliso.
Urhulumente waseTshayina ukhuphe uthotho lwemigaqo-nkqubo yokukhusela okusingqongileyo, efuna amashishini okanye amaziko anxulumene necandelo lemizi-mveliso ukuba alawule ngokungqongqo amanzi amdaka emizi-mveliso, nto leyo eye yadlala indima ethintelayo ekukhutshweni kwamanzi amdaka ngamashishini kwaye yakhuthaza ukukhula kwemfuno kwishishini lokunyanga amanzi amdaka emizi-mveliso. Ngokuhambela phambili kancinci kweeprojekthi zokunyanga amanzi amdaka emizi-mveliso ezinxulumeneyo kwiindawo ezahlukeneyo zemizi-mveliso, kwiindawo zophuhliso lwemizi-mveliso zobugcisa obuphezulu, nakwiindawo zemizi-mveliso zemvelo eTshayina, ubungakanani bemarike yokunyanga amanzi amdaka emizi-mveliso yaseTshayina buya kuqhubeka nokugcina umkhwa unyuka.
