I-ejenti yokukhipha i-heavy metal CW-15 iyisibambi sensimbi esindayo esingenabuthi futhi esivumelana nemvelo.Leli khemikhali lingakha inhlanganisela ezinzile enama-ion ensimbi amaningi aguquguqukayo futhi ahlukanisiwe emanzini angcolile, njengalezi:Fe2+,Ni2+,Pb2+,Cu2+,Ag+,Zn2+,Cd2+,Hg2+,Ti+kanye ne-Cr3+, bese ifinyelela inhloso yokususa ingqondo enzima. emanzini.Ngemuva kokwelashwa, i-Precipitation ayikwazi ukuchithwa yimvula, Ayikho inkinga yesibili yokungcola.
Khipha insimbi esindayo emanzini angcolile njengalokhu:amanzi angcolile e-desulfurization aphuma embonini yamandla ashiswe ngamalahle (inqubo ye-desulfurization emanzi) amanzi angcolile embonini yokucwenga yebhodi lesifunda Ephrintiwe (Ithusi elipulitiwe),Imboni ye-Electroplating (Zinc),i-Photographic rinse,Petrochemical Plant,Imboni yokukhiqiza izimoto kanye njalonjalo.
Iphephe kakhulu, ayinabo ubuthi, ayinaphunga elibi, ayikho into enobuthi ekhiqizwa ngemva kokwelashwa. Ingasetshenziswa ebangeni le-pH ebanzi, ingasetshenziswa emanzini angcolile ane-asidi noma ane-alkali.Lapho ama-ion ensimbi ehlala ndawonye, angasuswa ngesikhathi esifanayo.Uma ama-ion ensimbi esindayo esesimweni sikasawoti oyinkimbinkimbi (EDTA, tetramine njll) ongakwazi ukususwa ngokuphelele ngendlela ye-hydroxide precipitate, lo mkhiqizo ungawususa futhi.Lapho ididiyela insimbi esindayo, ngeke ivinjwe kalula usawoti ohlala ndawonye emanzini angcolile.Ukuhlukaniswa okuqinile-oketshezi kalula.Izinsalela zensimbi ezinzima zizinzile, ngisho naku-200-250℃ noma i-asidi ehlanjululwe.
Sinemishini yesimanjemanje.Imikhiqizo yethu ithunyelwa e-USA, e-UK njalo njalo, ijabulela isimo esihle phakathi kwamakhasimende Ekhwalithi Ephakeme Yamanzi Aqinile YaseChina Khipha I-Chlorine Fluoride Heavy Metals Sediments Ukungcola, Manje sinezixazululo ezine ezihamba phambili.Izinto zethu ezithengiswayo azithengiswa kuphela emkhakheni wamaShayina, kodwa futhi zamukelwa ezimakethe zamazwe ngamazwe.
Intengo Yekhwalithi Ephakeme Ye-Heavy Metal Khipha Umenzeli, Inkampani yethu ibilokhu igcizelela umgomo webhizinisi othi “Ikhwalithi, Ukwethembeka, kanye Nekhasimende Kuqala” okumanje sesizuze ukwethenjwa ngamaklayenti asekhaya naphesheya.Uma unentshisekelo kokuthengiswayo kwethu, khumbula ukungangabazi ukusithinta ukuze uthole ulwazi olwengeziwe.
