Indlela yokusebenzisa iikhemikhali zokucocwa kwamanzi 2

Indlela yokuSebenzisa imichiza yokucoca amanzi 3

Ngoku sinikela ingqalelo ngakumbi ekuphatheni amanzi amdaka xa ukungcoliseka kwendalo kusiba kubi.Iikhemikhali zokucocwa kwamanzi zizincedisi eziyimfuneko kwizixhobo zokucocwa kwamanzi amdaka.Ezi khemikhali ziyahluka kwiziphumo kunye nokusetyenziswa kweendlela.Apha sazisa iindlela zokusebenzisa kwiikhemikhali ezahlukeneyo zokunyanga amanzi.

I.Polyacrylamide usebenzisa indlela: (Kushishino, impahla, ilindle likamasipala njalo njalo)

1.dilute imveliso njengesisombululo se-0.1% -0,3%.Kungcono ukusebenzisa amanzi angathathi hlangothi ngaphandle kwetyuwa xa uxutywa.(Anje ngamanzi etephu)

2.Nceda uqaphele:Xa uhlambulula imveliso, nceda ulawule isantya sokuhamba komatshini wokudosa ozenzekelayo, ukunqanda i-agglomeration, imeko ye-fish-eye kunye nokuvaleka kwimibhobho.

3.Ukuvuselela kufuneka kube ngaphezu kwemizuzu engama-60 kunye ne-200-400 rolls / min.Kungcono ukulawula ukushisa kwamanzi njenge-20-30℃, oko kuyakukhawulezisa ukupheliswa.Kodwa nceda uqinisekise ukuba ubushushu bungaphantsi kwama-60℃.

4.Ngenxa yoluhlu olubanzi lwe-ph ukuba le mveliso inokulungelelanisa, i-dosage ingaba yi-0.1-10 ppm, inokulungelelaniswa ngokomgangatho wamanzi.

Indlela yokusebenzisa i-polyaluminium chloride: (isebenza kwishishini, ukuprinta kunye nokudaya, amanzi amdaka kamasipala, njl.

　　1. Dissolve imveliso eqinile ye-polyaluminium chloride ngamanzi kwinqanaba le-1:10, yivuselele kwaye usebenzise.

　　2. Ngokwe-turbidity eyahlukileyo yamanzi akrwada, idosi efanelekileyo inokumiselwa.Ngokuqhelekileyo, xa i-turbidity yamanzi akrwada i-100-500mg / L, i-dosage yi-10-20kg ngeetoni eziliwaka.

　　3. Xa i-turbidity yamanzi akrwada iphezulu, idosi inokunyuswa ngokufanelekileyo;xa i-turbidity iphantsi, idosi inokuncitshiswa ngokufanelekileyo.

　　4. I-Polyaluminium chloride kunye ne-polyacrylamide (i-anionic, i-cationic, i-non-ionic) isetyenziselwa kunye neziphumo ezingcono.
