Indlela Yokusebenzisa Amakhemikhali Okwelapha Amanzi 2

Indlela Yokusebenzisa Amakhemikhali Okwelapha Amanzi 3

Manje sesinaka kakhulu ukwelapha amanzi angcolile lapho ukungcola kwemvelo kuba kubi kakhulu. Amakhemikhali okwelapha amanzi ayizinsiza ezidingekayo emishinini yokwelapha amanzi angcolile. Lawa makhemikhali ahlukile ngemiphumela nangezindlela zokusebenzisa. Lapha sethula izindlela zokusebenzisa kumakhemikhali ahlukene okwelapha amanzi.

I. Indlela yokusebenzisa i-Polyacrylamide: (Yemboni, izindwangu, indle kamasipala njalo njalo)

1. hlanganisa umkhiqizo njengesixazululo esingu-0.1%-0,3%. Kungcono ukusebenzisa amanzi angathathi hlangothi angenasawoti lapho uxuba. (Njengamanzi ompompi)

2. Sicela uqaphele: Uma unciphisa umkhiqizo, sicela ulawule izinga lokugeleza komshini wokulinganisa ozenzakalelayo, ukuze ugweme ukuhlangana, isimo se-fish-eye kanye nokuvaleka kwamapayipi.

3. Ukuxuba kufanele kuthathe imizuzu engaphezu kwengu-60 ngama-roll angu-200-400/min. Kungcono ukulawula izinga lokushisa lamanzi njengo-20-30℃,lokho kuzosheshisa ukuqedwa. Kodwa sicela uqinisekise ukuthi izinga lokushisa lingaphansi kwama-60℃.

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

Indlela yokusebenzisa i-polyaluminum chloride: (isebenza embonini, ekunyatheliseni nasekudayeni, emanzini amdaka kamasipala, njll.)

　　1. Ncibilikisa umkhiqizo we-polyaluminum chloride oqinile ngamanzi ngesilinganiso esingu-1:10, uwuxube bese uwusebenzisa.

　　2. Ngokuya ngokuhlukahluka kokungamanzi aluhlaza, umthamo ofanele ungatholakala. Ngokuvamile, uma ukungamanzi aluhlaza kungu-100-500mg/L, umthamo ungaba ngu-10-20kg ngamathani ayinkulungwane.

　　3. Uma ukungcoliswa kwamanzi aluhlaza kuphezulu, umthamo ungandiswa ngokufanele; uma ukungcoliswa kuphansi, umthamo ungancishiswa ngokufanele.

　　4. I-Polyaluminum chloride kanye ne-polyacrylamide (i-anionic, i-cationic, ne-non-ionic) kusetshenziswa ndawonye ukuze kutholakale imiphumela engcono.
