Uwasebenzisa Kanjani Amakhemikhali Okwelapha Amanzi 2

Uwasebenzisa Kanjani Amakhemikhali Okwelashwa Kwamanzi 3

Manje sesinaka kakhulu ukwelashwa kwamanzi angcolile lapho ukungcola kwemvelo kuya ngokuya kuba kubi.Amakhemikhali okulungisa amanzi ayizinsizakusebenza ezidingekayo emishini yokuhlanza amanzi endle. Lapha sethula izindlela zokusebenzisa kumakhemikhali ahlukene wokuhlanza amanzi.

I-Polyacrylamide isebenzisa indlela: (Yezimboni, izindwangu, indle kamasipala njalonjalo)

Yehlisa umkhiqizo njengesixazululo esingu-0.1% -0,3%. Kungcono ukusebenzisa amanzi angathathi hlangothi ngaphandle kasawoti lapho uhluza (njengamanzi ompompi)

Sicela uqaphele: Lapho uhlunga umkhiqizo, sicela ulawule isilinganiso sokugeleza komshini wokulinganisa okuzenzakalelayo, ukugwema ukuhlangana, isimo senhlanzi nenso nokuvalwa kwamapayipi.

3.Ukuvuselela kufanele kube ngaphezu kwemizuzu engama-60 ngama-rolls angama-200-400 / min.Kungcono ukulawula ukushisa kwamanzi njengo-20-30 , lokho kuzosheshisa ukuncibilika.Kodwa sicela uqiniseke ukuthi izinga lokushisa lingaphansi kwama-60 .

4.Ngenxa yobubanzi be-ph ububanzi lo mkhiqizo ongazivumelanisa nawo, umthamo ungaba ngu-0.1-10 ppm, ungalungiswa ngokuya ngekhwalithi yamanzi.

 Ungayisebenzisa kanjani i-polyaluminum chloride: (kusebenza embonini, ekuphrinteni nasekudayeni, emanzini angcolile kamasipala, njll.)

   1. Chaza umkhiqizo oqinile we-polyaluminum chloride ngamanzi ngesilinganiso sika-1: 10, uvuse futhi uwasebenzise.

  2. Ngokwe-turbidity ehlukile yamanzi aluhlaza, isilinganiso esifanele singanqunywa. Ngokuvamile, lapho umswakama wamanzi aluhlaza kungu-100-500mg / L, umthamo ngu-10-20kg ngamathani ayizinkulungwane.

  3. Lapho umswakama wamanzi aluhlaza uphakeme, isilinganiso singakhushulwa ngokufanele; lapho i-turbidity iphansi, umthamo ungancishiswa ngokufanele.

  4. I-Polyaluminum chloride ne-polyacrylamide (anionic, cationic, non-ionic) zisetshenziswa ndawonye ukuthola imiphumela engcono.
