Amakhemikhali we-Securage Treatment

Ukwelashwa kwamanzi amdaka kuyinqubo eyinkimbinkimbi edinga ukusetshenziswa kwamakhemikhali ahlukahlukene ukusiza ukuhlanza amanzi. Ama-Flocculatants angomunye wamakhemikhali abalulekile adlala indima ebalulekile kwinqubo yokwelashwa kwendle. Lo mbhalo uzokwethula ngokuningiliziwe umthamo wamakhemikhali wendle wendle, izimboni zohlelo lokusebenza lwe-flocculants ekwelashweni kwendle, iqhaza lamakhemikhali wendle, kanye nokuphepha kokusebenzisa ama-flocculants.

Umthamo wamakhemikhali wokuthuthwa kwendle ancike kwikhwalithi yokukhucululwa kwendle, inqubo yokwelashwa kanye nezimo zangempela. Lokhu okulandelayo kuyizibonelo zemithamo yamakhemikhali ajwayelekile wendle wendle:

I-Polyaluminum Chloride (PAC):Isetshenziswa kakhulu njenge-flocculant, ingaphendula ngezinhlayiya ezingekho emthethweni ezikhokhiswayo ukukhiqiza ukulungisa ama-hydroxide micelles ukuze asuse ama-solids amisiwe kanye nama-ion athululiwe. Ngaphansi kwezimo ezijwayelekile, umthamo ngethani ngalinye lamanzi aluhlaza kumayelana namashumi ama-gramu, kepha umthamo wangempela udinga ukulungiswa ngokuya ngekhwalithi yamanzi eluhlaza kanye nemibandela yenqubo.

Polycrylamide (pam):isetshenziswe njenge-coabule yokuthuthukisa ukuqina nokuqina kwe-floc. Ngokuvamile isetshenziswa ngokuhambisana ne-polyaluminium chloride, umthamo ngethani ngalinye lamanzi avundwayo cishe amagremu ambalwa, kepha umthamo wangempela udinga ukulungiswa ngokufanele ngokwemibandela yenqubo.

Ama-Flocculatants asetshenziswa kabanzi ukwelashwa kwamanzi amdaka, ikakhulukazi kubandakanya izigaba ezilandelayo:

Ukwelashwa kwamanzi okudala kwezimboni: Amanzi angcolile wezimboni aqukethe inani elikhulu lama-solids amisiwe, ama-ion asindayo wensimbi kanye nokungcoliswa kwe-organic. Ukusetshenziswa kwama-flocculants kungasusa ngempumelelo lezi zingcoliso futhi kuhlanze amanzi angcolile.

Ukwelashwa kwendle ezifuywayo Ukusetshenziswa kwama-flocculants kungasusa ngempumelelo lezi zingcoliso nokwenza ngcono ikhwalithi yamanzi.

Ukwelashwa kwamanzi epulazini: Amanzi amdaka epulazi aqukethe inani elikhulu lento ephilayo, i-ammonia nitrogen nezinye izinto eziyingozi. Ukusetshenziswa kwama-flocculants kungasusa ngempumelelo lezi zingcoliso nokwenza ngcono ikhwalithi yamanzi.

Amanzi Amdaka Ezezimboni: Ukusetshenziswa Kwe-Flocculants kungasusa ngempumelelo ama-solids amisiwe, ama-ion anensimbi ezisindayo kanye nokungcoliswa kwe-organic emanzini futhi uthuthukise ikhwalithi yamanzi.

Imisebenzi yamakhemikhali wokuthuthwa kwendle ikakhulukazi ifaka phakathi izigaba ezilandelayo:

Ukususwa kwama-solids amiswe: ngesenzo se-flocculants, ama-solids amiswe ama-solids emanzi angaphansi komhlaba ahlanganiswe ngama-clumps ukwenza lula ukufakwa kanye nokuhlunga.

Ukususwa kwama-ion esindayo we-metal

Ukususwa kokungcoliswa kwe-organic: ngesenzo se-flocculants, ukungcola kwe-organic emanzi angcolile kuguqulwa kube yi-hydroxide stecitates noma i-oxid kwezinye izinto zokususwa kalula.

Ukulungiswa kwe-PH: Lungisa i-PH yamanzi angcolile ngesenzo se-Alkali noma i-Acid ukuze uhlanze amanzi wastewater.

Izinto okufanele uphawusheni lapho usebenzisa ama-flocculants:

Khetha i-Flocculant efanelekile: Ama-Flocculants ahlukene anemisebenzi ehlukile nemiphumela. Kuyadingeka ukukhetha i-flocculant efanele ngokwesimo sangempela.

Lawula umthamo wemithi: umthamo onganele uzothinta umphumela, futhi umthamo owedlulele uzobangela imfucuza nokulahleka komnotho. Ngakho-ke, kuyadingeka ukulawula umthamo ofanele ngokwesimo sangempela.

Govuza kahle: Govuza i-flocculant kanye namanzi kahle ukuze uchithe ngokuphelele futhi uphendule.

Nakisisa izinga lokushisa nenani le-PH: izinga lokushisa kanye nenani le-ph linomthelela emphumeleni we-flecculant futhi udinga ukulawulwa ngokucophelela.
