Imboni yephepha langasese ekukhiqizweni kwamanzi angcolile, igesi engcolile, izinsalela zemfucuza, izinto ezinobuthi nomsindo kungabangela ukungcola okukhulu kwemvelo, ukulawula kwayo, ukuvimbela noma ukuqeda ukwelashwa, ukuze indawo ezungezile ingathinteki noma ingathinteki kakhulu, isibe yingxenye ebalulekile embonini yephepha langasese. Imboni yephepha langasese ekungcolisweni kwamanzi inzima kakhulu, njengoba, ukugeleza kwamanzi (ngokuvamile kungaphezu kwamathani angu-300 amanzi ngethani le-pulp nephepha langasese), amanzi angcolile okuqukethwe okuphezulu kwezinto eziphilayo, isidingo se-oxygen yamakhemikhali (i-BOD) siphezulu, izinto eziqinile ezimisiwe (SS) ziningi, futhi ziqukethe izinto ezinobuthi, ezinombala onephunga elingavamile, ezibeka engcupheni ukukhula okuvamile kwezinto eziphilayo zasemanzini, ezithinta izimboni, ezolimo nezilwane kanye nezakhamuzi zamanzi kanye nokuhlelwa kwemvelo. Njengoba zinqwabelana eminyakeni edlule, izinto eziqinile ezimisiwe zizodaka echwebeni lomfula, futhi zikhiqize iphunga elinobuthi le-hydrogen sulfide, umonakalo omkhulu.
Imithombo yokungcola Izinqubo eziyinhloko embonini yephepha langasese ukulungiswa kwezinto zokusetshenziswa, ukugaya, ukubuyisa i-alkali, ukuhlanza, ukukopisha iphepha langasese njalo njalo. Inqubo yokulungisa izinto zokusetshenziswa ikhiqiza uthuli, amagxolo, izingcezu zokhuni, ukuphela kotshani; ukugaya kanye nokubuyisa i-alkali, inqubo yokuhlanza ikhiqiza igesi yokukhipha umoya, uthuli, amanzi angcolile, insalela yelayimu, njll.; inqubo yokubhala iphepha langasese ikhiqiza amanzi amhlophe, konke kuqukethe ukungcola. Ukungcola kwemboni yephepha langasese emvelweni kungahlukaniswa ngezigaba ezintathu zokungcola kwamanzi (Ithebula 1), ukungcola komoya (Ithebula 2) kanye nokungcola kwemfucuza eqinile.
Imfucuza eqinile yi-pulp ebolile, i-pulp slag, amagxolo, izingcezu zokhuni eziphukile, utshani, izimpande zotshani, utshani, udaka olumhlophe oluqukethe i-silica, i-lime slag, i-sulfuric iron ore slag, i-coal ash slag, njll., engenela endaweni, iphuma emanzini angcolile ukuze ingcolise amanzi kanye nemithombo yamanzi angaphansi komhlaba. Ukuphazamiseka komsindo nakho kuyinkinga enkulu embonini yephepha langasese.
Ukuvimbela nokulawula ukungcola kungahlukaniswa ngezigaba ezimbili: ukwelashwa okungenangozi endaweni kanye nokwelashwa kwamanzi amdaka ngaphandle kwendawo.
Iphepha langasese le-Yashi liyacutshungulwa kuyo yonke inqubo yomzimba. Inqubo yokukhiqiza ayilimazi umzimba womuntu. Umkhiqizo oqediwe awunazo izinsalela zamakhemikhali eziyingozi futhi unempilo futhi uphephile. Sebenzisa igesi yemvelo esikhundleni sikaphethiloli wendabuko ukuze ugweme ukungcola kwentuthu emoyeni. Susa inqubo yokucwebezela, gcina umbala wokuqala wemicu yezitshalo, unciphise ukusetshenziswa kwamanzi okukhiqiza, ugweme ukukhishwa kwendle yokucwebezela, futhi uvikele imvelo.
