Amanzi amdaka kwimizi-mveliso ngamanzi amdaka, ugutyulo kunye nolwelo olulahlwayo oluveliswa kwinkqubo yokuvelisa kwimizi-mveliso, ngokuqhelekileyo luqulathe imathiriyeli yokuvelisa kwimizi-mveliso, iimveliso eziphuma kwimveliso kunye nongcoliseko oluveliswa kwinkqubo yokuvelisa. Ukucocwa kwamanzi amdaka kwimizi-mveliso kubhekiselele kwinkqubo yokuphatha ngokufanelekileyo amanzi asetyenziswa kwinkqubo yokuveliswa kwemveliso yemveliso okanye ukukhutshwa kumzi-mveliso, enokuphatha ngokufanelekileyo amanzi amdaka aveliswa kwindawo yoshishino nokunciphisa ukungcoliseka kwendalo. Njengenye yezixhumanisi ezibalulekileyo kulawulo lokusingqongileyo, unyango lwamanzi amdaka amashishini luneempawu zonyango olungenabungozi, oluncitshisiweyo kunye nolwentlalontle, kwaye lusetyenziswa ngokubanzi kwimichiza, ukuprinta kunye nokudaya, iikhemikhali, intsimbi kunye nezinye iindawo zoshishino. Ukucocwa kwamanzi amdaka kwimizi-mveliso kuthatha amanyathelo onyango ahlukeneyo ngokobume bongcoliseko kumanzi amdaka. Ngokwenkqubo yayo yonyango, ingaba
yahlulwe ngendlela yonyango lomzimba, indlela yonyango lwemichiza, indlela yonyango lwe-physicochemical kunye nendlela yonyango lwebhayoloji. Phakathi kwabo, i-sludge esebenzayo kwindlela yonyango yebhayoloji Indlela inokuguqulwa kweekhemikhali eziphezulu kwaye inefuthe elihle kunyango lwezinto ezingcolileyo kumanzi amdaka e-organic industrial. Kungoku nje yeyona nkqubo isetyenziswa kakhulu kwimizi-mveliso yokucoca amanzi amdaka.
Ukuqaliswa kwemigaqo-nkqubo yokukhokela uphuhliso lokonga umbane kunye nokukhuselwa kwendalo kwishishini lokucocwa kwamanzi amdaka njengenye yekhonkco elibalulekileyo kulawulo lokusingqongileyo, ukucocwa kwamanzi amdaka kwimizi-mveliso kudlale indima ebalulekileyo kwimveliso yemizi-mveliso. Ngo-Oktobha 2010, iBhunga likaRhulumente laseTshayina licetyiswe "kwiSigqibo sokuKhawulezisa ukuLima kunye noPhuhliso lweSicwangciso esiPhuhlayo soShishino" ukuba ukugcinwa kwamandla kunye nokukhuselwa kwendalo kufuneka kuthathwe njengenye yamashishini asixhenxe asakhulayo, agxininise ekukhuthazeni amandla aphezulu. -ukugcina izixhobo zobugcisa kunye neemveliso, kunye nokuqonda ubugcisa obuphambili kwiindawo eziphambili. Ukuphumelela kuya kuqhuba uphuculo lwezinga elipheleleyo lokusebenza kakuhle kwamandla. Ngo-Apreli 2015, iBhunga likaRhulumente laseTshayina likhuphe iSicwangciso sokuSebenza soThintelo kunye noLawulo loNgcoliseko lwaManzi ("Amanzi alishumi"), luphawu lokuqala lolawulo lwaseTshayina lokucoca amanzi kwimizi mveliso. Izicwangciso zonyango olukhethekileyo kumashishini alishumi abalulekileyo afana neentsimbi ezingenayo i-ferrous, ukuprinta kunye nokudaya, i-coking, kunye nokuveliswa kwe-API kuyaphunyezwa, kwaye ukuguqulwa okucocekileyo kuphunyezwe ukufezekisa injongo yokulungisa ukungcoliswa kwamanzi. Ukongeza, i-"Ten Water Regulations" ikwabeke phambili amanyathelo anamandla angama-238 okulawula ungcoliseko kwiindawo ezidityanisiweyo zemizi-mveliso. Kungabonwa ukuba ngelixa kugxininise ekunciphiseni inani elipheleleyo lokukhutshwa okungcolileyo, i-China ihlawula ingqalelo ngakumbi ekuphuculweni komgangatho wokusingqongileyo wamanzi kunye nokuthintela kunye nokulawulwa kweengozi zendalo. Ngo-Okthobha ka-2017, kwingxelo yeNkongolo yeSizwe ye-19 yeQela lamaKomanisi laseChina, kwafuneka ukuba kuphuculwe imigangatho yokukhutshwa kongcoliseko, ukomeleza uxanduva lwabangcolisi, nokuphucula uvavanyo lwetyala lokusingqongileyo, ukuvezwa kolwazi olusisinyanzelo, isohlwayo esiqatha kunye nezinye iinkqubo. . iya kudlala indima enkulu yokukhokela. Kwelinye icala, kumthetho werhafu wokukhuselwa kwendalo, urhulumente waseTshayina uye wazisa imigaqo-nkqubo efanelekileyo. NgoDisemba ka-2017, iBhunga leSizwe laseTshayina labhengeza iMithetho yokuPhunyezwa koMthetho weRhafu yoKhuseleko lokusiNgqongileyo weRiphabhlikhi yaBantu baseTshayina, ifuna abahlawuli berhafu ukuba bakhuphe ungcoliseko lwamanzi olurhafiswayo oluxabiso loxinzelelo lungaphantsi kwe-30.0% yomgangatho wokukhutshwa kongcoliseko ochazwe ngu urhulumente kunye noorhulumente basekhaya, kunye nokunciphisa 75.0%. % irhafisi yokhuseleko lwendalo esingqongileyo; ukuba ukuxinwa kwezinto ezingcolileyo kungaphantsi kwe-50.0% yomgangatho wokukhutshwa kokungcola ochazwe ngurhulumente kunye noorhulumente basekhaya, irhafu yokukhusela indalo iya kuhlawuliswa ngesantya esincitshisiweyo se-50.0%. Emva kokuphunyezwa kwalo mgaqo-nkqubo, ukuqokelelwa kweendleko zogutyulo kwapheliswa, nto leyo ebaluleke kakhulu ekukhuseleni nasekuphuculeni indalo esingqongileyo, ukunciphisa ukukhutshwa kwezinto ezingcolisa umoya, nokukhuthaza ukwakhiwa kwempucuko yendalo.
Uvimba weDatha (Source): Ubonakaliswe yiSullivan Institute ubuchwepheshe bokucocwa kwamanzi kunye nendlela yenkqubo iya kubonisa indlela yophuhliso eyohlukeneyo. Phantsi kwemvelaphi yemigaqo-nkqubo yesizwe encomekayo, ubuchule bokusungula ubuchwepheshe bokucocwa kwamanzi amdaka eTshayina buphuculwe kakhulu, obukhuthaze ukuphuculwa kwenqanaba lokucocwa kwamanzi amdaka kwimizi-mveliso yaseTshayina. Ngenxa yokuntsokotha kwezinto ezingcolisa amanzi kwimizi-mveliso, it
kunzima kwitekhnoloji eyodwa ukufezekisa umphumo oyifunayo. Ke ngoko, amashishini okucoca amanzi amdaka kwimizi-mveliso kufuneka aqhube uphando oludityanisiweyo ngeendlela ezinqamlezileyo, ezihambelanayo, kunye ne-synergistic ngokusebenzisa itekhnoloji yokucoca amanzi abanzi, njengendibaniselwano yekhemikhali-yomzimba. Iindlela zonyango, iindlela zonyango ezidibeneyo zekhemikhali-zebhayoloji, njl., ukwenzela ukufezekisa iinjongo zokusebenza kakuhle, ukusetyenziswa okuphantsi kunye nokukhuselwa kwendalo. Ngakolunye uhlangothi, kwinkqubo yokujikeleza kwamanzi okupholisa kunye nomlinganiselo omkhulu wokusetyenziswa kwamanzi, ifomyula yekhompawundi esekwe kwisikali isetyenziswa kakhulu, kodwa ngenxa yokuba i-phosphorus-based corrosion and scale inhibitor kule fomyula inokusebenza njengesondlo kwiibhaktheriya kwaye i-algae emanzini, ebangela ungcoliseko lwamanzi I-Eutrophication kunye nongcoliseko lwamanzi. Ngoko ke, ngokuphuculwa kweteknoloji yokucoca amanzi amdaka aseTshayina, uphuhliso lwe-phosphorus ephantsi okanye engeyiyo i-phosphorus, i-non-nitrogen, i-biodegradable, i-multi-functional kunye neekhemikhali zokusingqongileyo zokucoca amanzi ziya kuba lukhokelo lophando oluqhelekileyo lokucocwa kwamanzi amdaka kwimizi-mveliso.
Urhulumente waseTshayina ukhuphe uluhlu lwemigaqo-nkqubo yokhuseleko lokusingqongileyo, efuna ukuba amashishini okanye amaziko anxulumene necandelo lemizi-mveliso alawule ngokungqongqo amanzi amdaka emizi-mveliso, adlale indima ethintelweyo ekukhutshelweni kwamanzi amdaka ngamashishini kwaye akhuthaze ukukhula kwemfuno kumanzi amdaka kwimizi-mveliso. ishishini lonyango. Ngokuqhubela phambili ngokuthe ngcembe kweeprojekthi zokucocwa kwamanzi amdaka kwimizi-mveliso eyahlukeneyo kwiipaki zemizi-mveliso, iindawo ezikumgangatho ophezulu wophuhliso lwemizi-mveliso, kunye neepaki zemizi-mveliso yendalo eTshayina, isikali semakethi yaseTshayina yokucocwa kwamanzi amdaka siya kuqhubeka nokugcina umkhwa wokunyuka.
