Amanzi angcolile ezimbonini angamanzi angcolile, indle kanye noketshezi olulahlwayo olukhiqizwa enqubweni yokukhiqiza ezimbonini, ngokuvamile equkethe izinto zokukhiqiza ezimbonini, imikhiqizo ephumayo kanye nezinto ezingcolisayo ezikhiqizwa inqubo yokukhiqiza. Ukuhlanzwa kwamanzi angcolile ezimbonini kubhekisela ohlelweni lokuphatha kahle amanzi asetshenziswa enqubweni yokukhiqizwa kwezimboni ukuze akhiqizwe noma akhishwe efektri, engaphatha kahle amanzi angcolile akhiqizwa emkhakheni wezimboni futhi ehlise ukungcoliswa kwemvelo. Njengenye yezixhumanisi ezibalulekile ekubusweni kwemvelo, ukwelashwa kwamanzi angcolile ezimbonini kunezici zokwelashwa okungenangozi, okuncishisiwe kanye nokuhlalisana kwabantu, futhi asetshenziswa kakhulu kwezemithi, ukuphrinta nokudaya, amakhemikhali, insimbi neminye imikhakha yezimboni. Ukwelashwa kwamanzi angcolile ezimbonini kuthatha izinyathelo zokwelashwa ezihlukene ngokuya ngemvelo yokungcola emanzini angcolile. Ngokwenqubo yayo yokwelapha, kungaba
ihlukaniswe ngendlela yokwelapha ngokomzimba, indlela yokwelapha ngamakhemikhali, indlela yokwelapha ye-physicochemical kanye nendlela yokwelapha yezinto eziphilayo. Phakathi kwazo, i-sludge ecushiwe endleleni yokwelapha yezinto eziphilayo Le ndlela inezinga eliphezulu lokuguqulwa kwamakhemikhali futhi inomphumela omuhle ekwelapheni ukungcola emanzini angcolile ezimbonini eziphilayo. Njengamanje kuyinqubo yokuhlanza amanzi angcolile yezimboni esetshenziswa kakhulu.
Ukwethulwa kwezinqubomgomo ezizoqondisa ukuthuthukiswa kokonga ugesi kanye nokuvikelwa kwemvelo embonini yokuhlanza amanzi angcolile ezimbonini Njengenye yezixhumanisi ezibalulekile ekubusweni kwemvelo, ukuhlanzwa kwamanzi angcolile ezimbonini kudlale indima ebalulekile ekukhiqizweni kwezimboni. Ngo-Okthoba 2010, uMkhandlu Kazwelonke WaseShayina wahlongoza "Esinqumweni Sokusheshisa Ukutshala Nokuthuthukiswa Kwezimboni Ezisafufusa Zamasu" ukuthi ukongiwa kwamandla kanye nokuvikelwa kwemvelo kufanele kuthathwe njengenye yezimboni eziyisikhombisa zamasu asafufusa, okugxile ekukhuthazeni ukusebenza kahle kwamandla. -ukonga izinto zokusebenza zobuchwepheshe kanye nemikhiqizo, kanye nokuqaphela ubuchwepheshe obubalulekile ezindaweni ezibalulekile. Impumelelo izoqhuba ukwenziwa ngcono kwezinga lilonke lokusebenza kahle kwamandla. Ngo-Ephreli 2015, uMkhandlu Wombuso waseShayina wakhipha Uhlelo Lokusebenza Lokuvimbela Nokulawulwa Kokungcoliswa Kwamanzi ("Amanzi Ayishumi"), okuwuphawu lokuqala lokuqondisa kwe-China ukuhlanza amanzi ezimbonini. Izinhlelo ezikhethekile zokwelashwa ezimbonini ezibalulekile eziyishumi njengezinsimbi ezingenayo insimbi, ukuphrinta nokudaya, ukupheka, nokukhiqizwa kwe-API ziyasetshenziswa, futhi uguquko oluhlanzekile luyenziwa ukuze kuzuzwe umgomo wokulungisa ukungcoliswa kwamanzi. Ngaphezu kwalokho, "Imithetho Eyishumi Yamanzi" iphinde yabeka phambili izinyathelo ezinamandla ezingama-238 zokulawula ukungcoliswa kwezindawo ezixubene nezimboni. Kungabonakala ukuthi ngenkathi igxile ekunciphiseni inani eliphelele lokukhishwa okungcolile, i-China inaka kakhulu ekuthuthukisweni kwekhwalithi yemvelo yamanzi kanye nokuvimbela nokulawula izingozi zemvelo. NgoMfumfu wezi-2017, embikweni weNgqungquthela Kazwelonke ye-19 yeQembu LamaKhomanisi laseChina, kwadingeka ukuba kuthuthukiswe amazinga okukhishwa kokungcola, kuqiniswe umthwalo wemfanelo wabangcolisi, futhi kuthuthukiswe ukuhlolwa kwezikweletu zemvelo, ukudalulwa kolwazi oluyisibopho, isijeziso esinzima nezinye izinhlelo. . izodlala indima enkulu yokuqondisa. Ngakolunye uhlangothi, emthethweni wentela wokuvikelwa kwemvelo, uhulumeni waseShayina futhi wethule izinqubomgomo ezifanele. NgoZibandlela wezi-2017, uMkhandlu Wombuso wase-China wamemezela Imithethonqubo Yokusetshenziswa Komthetho Wentela Wokuvikelwa Kwemvelo we-People's Republic of China, edinga abakhokhi bentela ukuthi bakhiphe ukungcola kwamanzi akhokhiswa intela okugxilwe kukho okungaphansi kuka-30.0% wezinga lokukhishwa okungcolile elishiwo ohulumeni basekhaya kanye nohulumeni basekhaya, ngokwehliswa ngo-75.0%. % intela yokuvikelwa kwemvelo; uma ukugcwala kokungcola kungaphansi kuka-50.0% wezinga lokukhipha ukungcola elishiwo uhulumeni kanye nohulumeni basekhaya, intela yokuvikelwa kwemvelo izokhokhiswa ngenani elincishisiwe lika-50.0%. Ngemva kokuqaliswa kwale nqubomgomo, ukuqoqwa kwezindleko zokukhucululwa kwendle kwaqedwa, okubaluleke kakhulu ekuvikeleni nasekuthuthukiseni imvelo, ukunciphisa ukungcola okungcolisayo, kanye nokugqugquzela ukwakhiwa kwempucuko yezemvelo.
Umthombo: Okufanekiselwa yi-Sullivan Institute Ubuchwepheshe bokwelashwa kwamanzi kanye nomzila wenqubo uzobonisa inkambiso yentuthuko ehlukahlukene. Ngaphansi kwesizinda sezinqubomgomo zikazwelonke ezivumayo, amandla amasha obuchwepheshe bokuhlanza amanzi angcolile ezimbonini zaseChina athuthukiswe kakhulu, okukhuthaze ukuthuthukiswa kwezinga lokuhlanzwa kwamanzi angcolile ezimbonini zaseChina. Ngenxa yobunkimbinkimbi bezinto ezingcolisa amanzi ezimbonini, it
kunzima kubuchwepheshe obubodwa ukufeza umphumela oyifunayo. Ngakho-ke, amabhizinisi okuhlanza amanzi angcolile ezimbonini kumele enze ucwaningo oludidiyelwe ngezindlela eziphambanayo, ezihambisanayo, nezisebenzisanayo ngokusebenzisa ubuchwepheshe obuphelele bokuhlanza amanzi, njengenhlanganisela yamakhemikhali nokomzimba. Izindlela zokwelapha, izindlela zokwelapha ezihlangene zamakhemikhali-zebhayoloji, njll., ukuze kuzuzwe izinhloso zokusebenza kahle kakhulu, ukusetshenziswa okuphansi nokuvikelwa kwemvelo. Ngakolunye uhlangothi, ohlelweni lwamanzi okupholisa ajikelezayo anengxenye enkulu yokusetshenziswa kwamanzi, ifomula yenhlanganisela esekwe esikalini isetshenziswa kakhulu, kodwa ngenxa yokuthi i-phosphorus-based corrosion and scale inhibitor kule fomula ingasebenza njengesakhi samagciwane futhi ulwelwe emanzini, okubangela ukungcoliswa kwamanzi I-Eutrophication kanye nokungcoliswa kwamanzi. Ngakho-ke, ngokuthuthukiswa kobuchwepheshe bokuhlanza amanzi angcolile ezimbonini zaseShayina, ukuthuthukiswa kwamakhemikhali e-phosphorus aphansi noma angewona i-phosphorus, okungeyona i-nitrogen, abolayo, asebenza ngezindlela eziningi futhi angangeni kwemvelo amakhemikhali okuhlanza amanzi azoba isiqondiso esivamile socwaningo lokuhlanzwa kwamanzi angcolile ezimbonini.
Uhulumeni waseShayina ukhiphe uchungechunge lwezinqubomgomo zokuvikela imvelo, ezidinga ukuthi amabhizinisi noma izinhlaka ezihlobene nenkundla yezimboni zilawule ngokuqinile amanzi angcolile ezimbonini, okudlale indima evimbela ukuchithwa kwamanzi angcolile ngamabhizinisi futhi kwakhuthaza ukukhula kwesidingo emanzini angcolile ezimbonini. imboni yokwelapha. Ngokuthuthuka kancane kancane kwamaphrojekthi okuhlanza amanzi angcolile ezimbonini ahlobene namapaki ezimboni ahlukahlukene, izindawo zokuthuthukiswa kwezimboni zobuchwepheshe obuphambili, namapaki ezimboni zemvelo e-China, isilinganiso semakethe yokuhlanza amanzi angcolile yezimboni yaseChina sizoqhubeka nokugcina inkambiso ikhuphuka.
