Mashandisirwo Emakemikari Ekuchenesa Mvura 3
Iye zvino tava kunyanya kutarisisa pakuchenesa mvura yakasviba kana kusvibiswa kwezvakatipoteredza kuri kuwedzera kuipa. Makemikoro ekuchenesa mvura anobatsira pakushandisa michina yekuchenesa mvura yetsvina. Makemikoro aya akasiyana pakushanda uye pakushandisa nzira dzakasiyana. Pano tinotsanangura nzira dzekushandisa pamakemikari akasiyana ekuchenesa mvura.
I. Polyacrylamide uchishandisa nzira: (Yemaindasitiri, machira, tsvina yemuguta nezvimwewo)
1. Sanganisa chigadzirwa ichi se 0.1%-0,3%. Zviri nani kushandisa mvura isina munyu kana uchichisanganisa. (Semvura yemupombi)
2. Ndapota cherechedzai: Paunenge uchideredza chigadzirwa, ndapota dzorai mwero wekuyerera kwemuchina weAutomatic dosing, kudzivirira kuungana, mamiriro ezvinhu e-fish-eye uye kuvharika kwemapaipi.
3. Kukurunga kunofanira kuitwa kwemaminitsi anopfuura makumi matanhatu ne200-400 rolls/min. Zviri nani kudzora tembiricha yemvura se20-30℃, izvo zvichaita kuti kunyungudika kwechinhu ichi kukurumidze. Asi ndapota iva nechokwadi chekuti tembiricha iri pasi pe60℃.
4. Nekuda kwehuwandu hwakakura hwe ph hunogona kugadziriswa nechigadzirwa ichi, chiyero chacho chinogona kuva 0.1-10 ppm, chinogona kugadziriswa zvichienderana nehunhu hwemvura.
Mashandisirwo epolyaluminum chloride: (inoshanda kumaindasitiri, kudhinda nekudhaya, mvura yakasviba yemuguta, nezvimwewo)
1. Nyungudutsa chigadzirwa chakasimba chepolyaluminum chloride nemvura ine chiyero che1:10, chikurunga wobva washandisa.
2. Zvichienderana nekusiyana kwemvura isina kucheneswa, chiyero chakakodzera chinogona kusarudzwa. Kazhinji, kana kusviba kwemvura isina kucheneswa kuri 100-500mg/L, chiyero chacho chiri 10-20kg patani chiuru.
3. Kana mvura isina kusviba yakawanda, chiyero chinogona kuwedzerwa zvakakodzera; kana mvura isina kusviba yakaderera, chiyero chinogona kuderedzwa zvakakodzera.
4. Polyaluminum chloride nepolyacrylamide (anionic, cationic, non-ionic) zvinoshandiswa pamwe chete kuti zvive nani.
