Indlela yokusebenzisa iikhemikhali zokucoca amanzi 2

Indlela yokusebenzisa iikhemikhali zokucoca amanzi 3

Ngoku sinikela ingqalelo engakumbi ekunyangweni kwamanzi amdaka xa ungcoliseko lokusingqongileyo lusiya lusiba mandundu. Iikhemikhali zonyango lwamanzi zizinto ezincedisayo ezifunekayo kwizixhobo zonyango lwamanzi amdaka. Ezi khemikhali zahlukile ngeziphumo kunye neendlela zokusebenzisa. Apha sichaza iindlela zokusebenzisa kwiikhemikhali ezahlukeneyo zonyango lwamanzi.

I. Indlela yokusebenzisa iPolyacrylamide: (Kwimizi-mveliso, impahla yelaphu, amanzi amdaka kamasipala njalo njalo)

1. Nyibilikisa imveliso njengesisombululo se-0.1%-0,3%. Kungcono ukusebenzisa amanzi angathathi cala angenatyuwa xa unyibilikisa. (Njengomanzi epompo)

2. Nceda uqaphele: Xa uxuba imveliso, nceda ulawule izinga lokuhamba komatshini wokulinganisa ozenzekelayo, ukuze uphephe ukuhlangana, imeko ye-fish-eye kunye nokuvaleka kwemibhobho.

3. Ukuxuba kufanele kuthathe imizuzu engaphezu kwama-60 kunye neeroli ezingama-200-400/min. Kungcono ukulawula ubushushu bamanzi njenge-20-30℃Oko kuya kukhawulezisa ukuchithwa. Kodwa nceda uqinisekise ukuba ubushushu bungaphantsi kwama-60℃.

4. Ngenxa yobubanzi be-ph obunokuhlengahlengiswa yile mveliso, idosi ingaba yi-0.1-10 ppm, ingalungiswa ngokomgangatho wamanzi.

Indlela yokusebenzisa i-polyaluminum chloride: (isebenza kushishino, ukushicilela kunye nokudaya, amanzi amdaka kamasipala, njl.njl.)

　　1. Nyibilikisa imveliso ye-polyaluminum chloride eqinileyo ngamanzi ngomlinganiselo we-1:10, uyixube uze uyisebenzise.

　　2. Ngokweendlela ezahlukeneyo zokufuma kwamanzi aluhlaza, idosi efanelekileyo inokumiselwa. Ngokubanzi, xa ukufuma kwamanzi aluhlaza kuyi-100-500mg/L, idosi yi-10-20kg ngeetoni eziliwaka.

　　3. Xa amanzi aluhlaza exineneyo, umthamo unganyuswa ngokufanelekileyo; xa amanzi amdaka exineneyo, umthamo ungancitshiswa ngokufanelekileyo.

　　4. I-Polyaluminum chloride kunye ne-polyacrylamide (anionic, cationic, non-ionic) zisetyenziswa kunye ukuze kufunyanwe iziphumo ezingcono.
