Ngokuthuthuka okusheshayo kwezimboni kanye nokufuduka kwabantu emadolobheni, amanzi aphezulu angcolile asephenduke inkinga enkulu yezemvelo. Amanzi angaphansi kokuhlushwa okuphezulu aqukethe kuphela inani elikhulu lezinto eziphilayo, izinto ezi-inorganic, izinsimbi ezisindayo kanye nezinye izinto eziyingozi, futhi ukugxila kwalo kude kakhulu kudlula umthamo wokuqamba wezindawo zokulashwa kwamanzi okujwayelekile. Ngakho-ke, ukwelashwa kwamanzi okuhlushwa okuphezulu nokukhululwa kwamanzi kubaluleke kakhulu.
1. Ukuchazwa kanye nezimpawu zamanzi angcolile agxile kakhulu
Ukuqoqwa okuphezulu kwamanzi amdaka, kuvame ukubhekisa emanzini angcolile aqukethe ukugxila okuphezulu kwezinto eziphilayo, izinsimbi ezisindayo, izinto ezinobuthi kanye nezinobungozi nokunye okungcolile nokunye ukungcoliswa kwezinye izinguquko nokunye okungcolile nokunye okungcolile nokunye ukungcoliswa kwezinye izinto. Okuqukethwe kokungcoliswa kwamanzi angcolile kudlula amanzi amdaka ajwayelekile futhi kunzima ukwelapha. Kungaqukatha izinhlobo eziningi ezahlukene zokungcola, njengezinto eziphilayo, izinsimbi ezisindayo, nezinto ezinemisebe. Ezinye zokungcola zingaba nomphumela wokuvimbela ama-microorganisms, okuthinta umphumela wezokwelapha eziphilayo, futhi kunzima ukususwa izindlela ezejwayelekile zokwelashwa.
2. Izimo zesizukulwane samanzi aphezulu okuhlushwa
Ukukhiqizwa kwamakhemikhali: Kukhiqizwe amanzi angcolile ngesikhathi sokukhiqizwa kwamakhemikhali kuvame ukuqukethe inani elikhulu lezinto eziphilayo, izinsimbi ezisindayo nokunye ukungcola.
Imboni yezemithi: Amanzi amdaka amakhermaceutical ajwayele ukugxila kakhulu kwezinto eziphilayo, ama-antibiotic, njll., Futhi kunzima ukwelapha.
Imboni ye-Dyestuff kanye ne-Textile Emboni: Kukhiqizwe amanzi amdaka avela kulezi zimboni ngokuvamile kuqukethe inani elikhulu lobunzima bokulimaza ama-organics ne-chromatic.
I-Electroplating neMetallurgy: Inqubo ye-electroplating ne-metallurgy izokhiqiza amanzi angcolile aqukethe izinsimbi ezisindayo nezinto ezinobuthi.
I-3. Ubuchwepheshe obukhulu bokuphathwa kwendle okuhlushwa indle
Isitshalo sokwelashwa okuhlangenwe kwesendle okuphezulu, imvamisa ngezindlela zomzimba noma zamakhemikhali ukususa izinhlayiya ezinkulu emanzi angcolile, ama-solids amisiwe, njll., Ukwakha izimo zokwelashwa okulandelayo. Kuzobe nakho kudlula njenge-fenton oxidation, oozone oxidation kanye nezinye ubuchwepheshe obuthuthukile boxidation, esizukulwaneni se-oxidants eqinile esizoba nzima ukungcolisa izinto eziphilayo ezintweni ezingonakaliswe kalula. I-metabolism yama-microorganisms isetshenziselwa ukususa izinto eziphilayo kumanzi amdaka. Kumanzi amdaka agxile kakhulu, inhlanganisela yezinqubo ezinjenge-anaerobic ne-aerobic ingahle isetshenziselwe ukuthuthukisa ukwelashwa. Izinto ezincibilikisiwe kumanzi angcolile nazo zingasuswa ngezindlela zomzimba ngokusebenzisa amasu wokuhlukanisa we-membrane anjenge-ultrafiltration kanye ne-reverse osmosis. Ubuchwepheshe obukhulu be-Metal Treatment Technologies obunjenge-chemipitation teapiture, i-ini Exchange kanye ne-adsorption kusetshenziselwa ukususa ama-ion ashubile avela kumanzi amdaka.
Ngakho-ke, ekuqoqweni okuphezulu kwesitshalo sokwelashwa kwendle, ukuqinisekisa ukuthi i-Effant ihlangabezana nezinga, ukukhethwa okunengqondo kwenqubo yokwelashwa, ukuqinisa ukwelashwa okujwayelekile, uma kutholakala amapharamitha okusebenza kanye nokuhlolwa okujwayelekile, uma kutholakala izinkinga, thatha izinyathelo ezifika ngesikhathi ukuze uguqule.
Isitshalo sesethi sokuhlanza indle okuhlushwa ngenxa yohlobo olukhethekile lwekhwalithi yalo yamanzi, ngoba imishini inezidingo zobuchwepheshe eziqinile, isidingo sokuba nobuchwepheshe bomkhiqizo omuhle, isipiliyoni sezimo zasendaweni, ukuze siqinisekise ukuthi ukugxilwa okuphezulu kwemishini yokwelashwa kwamanzi okungcolile ukuze kuhlangatshezwane namazinga we-affaent. Ukuvikelwa Kwezemvelo Ukuvikelwa Kweminyaka Elikhulu Leminyaka Emkhakheni Wamanzi Omncane Emkhakheni Wamanzi Omdaka, ku-Jiangsu, kukhazimulayo ezweni lonke, ebheke phesheya kwezilwandle, neqembu eliqinile lobuchwepheshe bekhwalithi yobuchwepheshe.
