Ngomkhawulo we-decuting we- "electroplant propetant defate standard" ngokwengeziwe, manje, ukwelashwa kwamanzi amdaka abuhlungu sekugxile ekunakekelweni okukhulu kwezimboni. Manje okuvame ukuphathwa ngamanzi anzima wensimbi angcolile kanye noFree State, phakathi kwawo, amanzi angcolile wensimbi anobuthi anobuthi obuqinile, ukwelashwa kunzima. Futhi ngenxa ye-biochemistry ephansi yalolu hlobo lwekhwalithi yamanzi, ngakho-ke ukwelashwa okungokomzimba okungokomzimba nangamakhemikhali, ukwelashwa okuvamile kusho ukusetshenziswa kwe-ejenti yokuqhekeka, i-sodium sulfide kanye nokwelashwa kwamakhemikhali.
I-Sodium Sulfide inomphumela wokuqhekeka okuningana nokungcoliswa kwensimbi esindayo yensimbi, kanye nentengo ephansi, ngakho-ke imboni yamanje isebenzisa kakhulu i-sodium sulfide ukwelapha amanzi angcolile we-wastewater. Leli phepha lizethula ukusetshenziswa kwe-sodium sulfide kanye nokungeza izinyathelo, imininingwane imi kanjena elandelayo.
Eqinisweni, isinyathelo sokungezeleli se-sodium sulfide sinqunywa ikakhulu ngokwesimo sangempela sendawo, okulandelayo zinezinyathelo ezimbalwa zokusetshenziswa kwenqubo yokwelashwa yendle ebekiwe.
1. I-sodium sulfide ingezwa ekugcineni kwethangi elilawulayo. Ngoba i-sodium sulfide imvelo ayikwazi ukusetshenziswa ngaphansi kwezimo ze-acidic, ngakho-ke kuyadingeka ukwengeza i-alkali ngaphambi kokusebenzisa, ukuze kuvikeleke ukwenziwa kwezinto ezinobuthi, kepha futhi nokuqinisekisa ukwelashwa okusebenzayo, nesimo esisebenzayo futhi mahhala I-State Metal Ion Reaction to Sulfide teppitation.
2. Faka i-sodium sulfide ethangini lokuphendula. Uma ensimini yokulungisa iphutha, izimo zangempela, i-sodium sulfide zingangezwa endaweni ephukile ngemuva (kwe-alkaline) yokuphendula, ngoba i-ion yensimbi yensimbi yephulwe ibe yi-ion yamahhala yensimbi, ngakho-ke echibini lokuphendula ngemuva kokuphulwa kabusha ukwelashwa kwe-sodium sulfide kusiza kakhulu ukuthuthukisa umphumela wokwelashwa kokungcoliswa kwensimbi.
3. Faka i-sodium sulfide ekugcineni kwangaphambili kwethangi lokuhlangana. Ngaphambi kokwelashwa kwe-coagation, i-sodium sulfide yengezwa ukucacisa i-ion yensimbi. Ngoba iningi lama-ions wensimbi selixazululiwe, ukwelashwa okulandelanayo okulandelayo kungaphatha futhi ama-ion wensimbi asele, ukuze izinga lamanzi lihlanzeke kanye nezinga
