Asetshenziswa Kanjani Amakhemikhali Okuhlanza Amanzi 1
Manje sesinaka kakhulu ukwelapha amanzi angcolile lapho ukungcoliswa kwemvelo kuba kubi kakhulu.Amakhemikhali okuhlanza amanzi ayizisetshenziswa ezidingekayo ezisetshenziswayo zokuhlanza amanzi endle.Lawa makhemikhali ahlukile emiphumeleni nasekusebenziseni izindlela. Lapha sethula izindlela zokusebenzisa kumakhemikhali ahlukene okuhlanza amanzi.
I-I.Polyacrylamide isebenzisa indlela:(Okwezimboni, izindwangu, indle kamasipala nokunye)
1.dilute umkhiqizo njengesixazululo esingu-0.1% -0,3%. Kungcono ukusebenzisa amanzi angathathi hlangothi ngaphandle kukasawoti uma uhlanjululwa.(njengamanzi ompompi)
2. Sicela uqaphele: Lapho uhlanza umkhiqizo, sicela ulawule izinga lokugeleza lomshini wokudosa okuzenzakalelayo, ukugwema ukuhlangana, isimo seso lezinhlanzi kanye nokuvinjwa kwamapayipi.
3.Ukushukumisa kufanele kube ngaphezu kwemizuzu engama-60 nama-rolls/mins angu-200-400.Kungcono ukulawula izinga lokushisa lamanzi njengo-20-30 ℃,lokho kuzosheshisa ukuchithwa.Kodwa sicela uqinisekise ukuthi izinga lokushisa lingaphansi kuka-60 ℃.
4.Ngenxa yobubanzi obubanzi be-ph lo mkhiqizo ongakwazi ukuzivumelanisa, umthamo ungaba ngu-0.1-10 ppm, ungalungiswa ngokuvumelana nekhwalithi yamanzi.
Isetshenziswa kanjani i-coagulant ye-paint mist: (Amakhemikhali ikakhulukazi asetshenziselwa ukuhlanza indle kapende)
1. Emsebenzini wokudweba, ngokuvamile engeza i-coagulant yenkungu A ekuseni, bese ufutha upende ngokujwayelekile. Ekugcineni, engeza inkungu kapende i-coagulant B isigamu sehora ngaphambi kokuphuma emsebenzini.
2. Iphuzu lomthamo we-coagulant yenkungu kapende I-ejenti isendaweni yokungena amanzi azungezayo, futhi indawo yokudosa ye-ejenti B ilapho kuphuma khona amanzi ajikelezayo.
3. Ngokwenani lopende wesifutho kanye nenani lamanzi ajikelezayo, lungisa inani lenkungu yepende coagulant A no-B ngesikhathi.
4. Ukulinganisa inani le-PH lamanzi ajikelezayo njalo kabili ngosuku ukuze ligcinwe phakathi kuka-7.5-8.5, ukuze le ejenti ibe nomphumela omuhle.
5. Lapho amanzi ajikelezayo esetshenziswa isikhathi esithile, i-conductivity, inani le-SS kanye nokuqukethwe okuqinile okumisiwe kwamanzi ajikelezayo kuzodlula inani elithile, okuzokwenza le-ejenti ibe nzima ukuncibilika emanzini ajikelezayo futhi ngenxa yalokho ithinte umphumela. yale ejenti. Kunconywa ukuhlanza ithangi lamanzi bese ubuyisela amanzi ajikelezayo ngaphambi kokusetshenziswa. Isikhathi sokushintsha amanzi sihlobene nohlobo lopende, inani lopende, isimo sezulu kanye nezimo ezithile zemishini yokumboza, futhi kufanele isetshenziswe ngokuhambisana nezincomo zochwepheshe bendawo.
