Asetshenziswa Kanjani Amakhemikhali Okuhlanza Amanzi 3

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.Ukugqugquzela kufanele kube ngaphezu kwemizuzu engama-60 nama-rolls/mins angama-200-400.Kungcono ukulawula izinga lokushisa lamanzi njengo-20-30.℃,lokho kuzosheshisa ukuqedwa.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-polyaluminium chloride: (isebenza embonini, ukuphrinta nokudaya, amanzi angcolile kamasipala, njll.)

　　1. Chaza umkhiqizo oqinile we-polyaluminium chloride ngamanzi ngesilinganiso esingu-1:10, ugovuze futhi usebenzise.

　　2. Ngokuya nge-turbidity ehlukene yamanzi aluhlaza, umthamo ophelele unganqunywa. Imvamisa, lapho ukungcola kwamanzi aluhlaza kungu-100-500mg/L, umthamo ungama-10-20kg amathani ayinkulungwane.

　　3. Uma ukungcola kwamanzi aluhlaza kuphezulu, umthamo ungakhuliswa ngokufanelekile; lapho i-turbidity iphansi, umthamo ungancishiswa ngokufanelekile.

　　4. I-Polyaluminium chloride ne-polyacrylamide (i-anionic, i-cationic, i-non-ionic) isetshenziswa ndawonye ukuze kube nemiphumela engcono.
