Amanzi angcolile asezimbonini amanzi angcolile, indle kanye noketshezi olungcolile olukhiqizwa enkambisweni yokukhiqiza yezimboni, ngokuvamile aqukethe izinto zokukhiqiza zezimboni, imikhiqizo engaphansi kanye nokungcola okukhiqizwa enkambisweni yokukhiqiza. Ukwelashwa kwamanzi angcolile asezimbonini kubhekisela enkambisweni yokuphatha kahle amanzi asetshenziswa enkambisweni yokukhiqiza yezimboni yokukhiqiza noma yokukhipha efektri, okungaphatha kahle amanzi angcolile akhiqizwa ensimini yezimboni futhi kunciphise ukungcola kwemvelo. Njengenye yezixhumanisi ezibalulekile ekubusweni kwemvelo, ukwelashwa kwamanzi angcolile asezimbonini kunezici zokwelashwa okungenangozi, okuncishisiwe kanye nokwezenhlalo, futhi kusetshenziswa kabanzi ekwelapheni, ekunyatheliseni nasekudayeni, kumakhemikhali, ensimbi nakwezinye izinkambu zezimboni. Ukwelashwa kwamanzi angcolile asezimbonini kuthatha izinyathelo ezahlukene zokwelashwa ngokuya ngohlobo lokungcola emanzini angcolile. Ngokwenqubo yokwelapha, kungaba
ihlukaniswe ngendlela yokwelapha ngokomzimba, indlela yokwelapha ngamakhemikhali, indlela yokwelapha nge-physicochemical kanye nendlela yokwelapha ngebhayoloji. Phakathi kwazo, i-activated sludge in biological treatment method Le ndlela inamandla aphezulu okuguqula amakhemikhali futhi inethonya elihle ekwelapheni ukungcola emanzini angcolile ezimbonini eziphilayo. Njengamanje inqubo yokwelapha amanzi angcolile ezimbonini esetshenziswa kakhulu.
Ukwethulwa kwezinqubomgomo zokuqondisa ukuthuthukiswa kokonga amandla nokuvikelwa kwemvelo embonini yokwelapha amanzi amdaka ezimbonini Njengenye yezixhumanisi ezibalulekile ekubusweni kwemvelo, ukwelashwa kwamanzi amdaka ezimbonini kudlale indima ebalulekile ekukhiqizweni kwezimboni. Ngo-Okthoba 2010, uMkhandlu Kahulumeni waseShayina waphakamisa "esinqumweni Sokusheshisa Ukutshala Nokuthuthukiswa Kwezimboni Ezisafufusa Ezinesu" ukuthi ukongiwa kwamandla nokuvikelwa kwemvelo kufanele kubhekwe njengenye yezimboni eziyisikhombisa ezisafufusa ezinamasu, kugxilwe ekukhuthazeni imishini nemikhiqizo yobuchwepheshe eyonga amandla esebenza kahle kakhulu, kanye nokuqaphela ubuchwepheshe obubalulekile ezindaweni ezibalulekile. Intuthuko izothuthukisa izinga eliphelele lokusebenza kahle kwamandla. Ngo-Ephreli 2015, uMkhandlu Kahulumeni waseShayina wakhipha Uhlelo Lokusebenza Lokuvimbela Nokulawula Ukungcola Kwamanzi ("Amanzi Ayishumi"), oluyisibonakaliso sokuqala sokuqondisa kweShayina ukwelashwa kwamanzi ezimbonini. Izinhlelo zokwelapha ezikhethekile zezimboni eziyishumi ezibalulekile njengezinsimbi ezingenayo insimbi, ukuphrinta nokudaya, ukuphekwa kwe-cooking, kanye nokukhiqizwa kwe-API kuyaqaliswa, futhi ukuguqulwa okuhlanzekile kuyaqaliswa ukufeza umgomo wokulungisa ukungcola kwamanzi. Ngaphezu kwalokho, "Imithethonqubo Yamanzi Eyishumi" iphinde yabeka izinyathelo ezinamandla ezingu-238 zokulawula ukungcola ezindaweni zezimboni. Kungabonakala ukuthi ngenkathi igxile ekunciphiseni inani eliphelele lokungcola, iShayina inaka kakhulu ukuthuthukiswa kwekhwalithi yemvelo yamanzi kanye nokuvimbela nokulawula izingozi zemvelo. Ngo-Okthoba 2017, embikweni we-19th National Congress of the Communist Party of China, kwakudingeka ukuthuthukisa amazinga okukhishwa kokungcola, ukuqinisa umthwalo wemfanelo wabangcolisi, nokuthuthukisa ukuhlolwa kwesikweletu semvelo, ukudalulwa kolwazi okuphoqelekile, isijeziso esinzima nezinye izinhlelo. kuzodlala indima enkulu yokuqondisa. Ngakolunye uhlangothi, emthethweni wentela yokuvikelwa kwemvelo, uhulumeni waseShayina wethule nezinqubomgomo ezifanele. NgoDisemba 2017, uMkhandlu Wezwe waseShayina wamemezela Imithethonqubo Yokusetshenziswa KoMthetho Wentela Yokuvikelwa Kwemvelo weRiphabhulikhi Yabantu baseShayina, edinga abakhokhi bentela ukuba bakhiphe ukungcola kwamanzi okukhokhiswa intela okunenani eliphansi kune-30.0% yendinganiso yokukhishwa kokungcola echazwe ohulumeni besifundazwe nabasekhaya, ngokunciphisa okungu-75.0%. % intela yokuvikelwa kwemvelo; Uma ukugcwala kokungcola kungaphansi kuka-50.0% wendinganiso yokukhishwa kokungcola ebekwe ohulumeni bezifundazwe nabasekhaya, intela yokuvikelwa kwemvelo izokhokhiswa ngesilinganiso esincishisiwe esingu-50.0%. Ngemva kokusetshenziswa kwale nqubomgomo, ukuqoqwa kwezindleko zokungcola kwaqedwa, okubaluleke kakhulu ekuvikeleni nasekuthuthukiseni imvelo, ekunciphiseni ukukhishwa kokungcola, kanye nokukhuthaza ukwakhiwa kwempucuko yezemvelo.
Umthombo: Okufanekiswe yiSullivan Institute Ubuchwepheshe bokwelapha amanzi kanye nendlela yenqubo kuzobonisa ukuthambekela okuhlukahlukene kwentuthuko. Ngaphansi kwesizinda sezinqubomgomo zikazwelonke ezinhle, ikhono lokusungula ubuchwepheshe bokwelapha amanzi amdaka ezimbonini zaseShayina lithuthukiswe kakhulu, okuye kwakhuthaza ukuthuthukiswa kwezinga lokwelapha amanzi amdaka ezimbonini zaseShayina. Ngenxa yobunzima bokungcola kwamanzi ezimbonini,
Kunzima ukuthi ubuchwepheshe obubodwa bufinyelele umphumela ofiselekayo. Ngakho-ke, amabhizinisi okwelapha amanzi amdaka asezimbonini adinga ukwenza ucwaningo oluhlanganisiwe ngezindlela ezihlanganisayo, ezihambisanayo, nezisebenzisanayo ngokusebenzisa ubuchwepheshe obuphelele bokwelapha amanzi, njengokuhlanganiswa kwamakhemikhali nemizimba. Izindlela zokwelapha, izindlela zokwelapha ezihlanganisiwe zamakhemikhali nezemvelo, njll., ukuze kufezwe imigomo yokusebenza kahle kakhulu, ukusetshenziswa okuphansi kanye nokuvikelwa kwemvelo. Ngakolunye uhlangothi, ohlelweni lwamanzi okupholisa olujikelezayo olunengxenye enkulu yokusetshenziswa kwamanzi, ifomula yenhlanganisela esekelwe esikalini isetshenziswa kakhulu, kodwa ngoba isithiyo sokugqwala nesikali esisekelwe ku-phosphorus kule fomula singasebenza njengesakhi samagciwane kanye nolwelwe emanzini, okubangela ukungcola kwamanzi. I-Eutrophication kanye nokungcola kwamanzi. Ngakho-ke, ngokuthuthukiswa kobuchwepheshe bokwelapha amanzi amdaka asezimbonini zaseShayina, ukuthuthukiswa kwamakhemikhali okwelapha amanzi ane-phosphorus ephansi noma angenayo i-phosphorus, angenayo i-nitrogen, abolayo, asebenza kahle futhi anobungani nemvelo azoba yisiqondiso socwaningo esiyinhloko sokwelashwa kwamanzi amdaka asezimbonini.
Uhulumeni waseShayina ukhiphe uchungechunge lwezinqubomgomo zokuvikela imvelo, ezidinga amabhizinisi noma izinhlangano ezihlobene nensimu yezimboni ukuthi zilawule ngokuqinile amanzi angcolile ezimbonini, okudlale indima evimbelayo ekukhishweni kwamanzi angcolile ngamabhizinisi futhi kwakhuthaza ukukhula kwesidingo embonini yokwelapha amanzi angcolile ezimbonini. Ngokuthuthuka kancane kancane kwamaphrojekthi okwelapha amanzi angcolile ezimbonini ahlobene ezindaweni ezahlukene zezimboni, ezindaweni zokuthuthukiswa kwezimboni zobuchwepheshe obuphezulu, kanye nasezindaweni zezimboni zemvelo eShayina, ubukhulu bemakethe yokwelapha amanzi angcolile ezimbonini zaseShayina buzoqhubeka nokugcina ukuthambekela okuphezulu.
