I-Polyacrylamide (Pam) kanye nesicelo sayo ekwelashweni kwamanzi

Ukulawulwa kokungcola kwamanzi kanye nokubusa kuyingxenye ebalulekile yokuvikelwa kwemvelo kanye nokulahlwa kokwelashwa kwamanzi okungcola kuba nokunakwa ngokwengeziwe.

I-PolyAcrylamide (Pam), i-polymer engenantambo eqondile, iyindima ebaluleke kakhulu emkhakheni wokwelashwa kwamanzi ngenxa yesisindo esiphakeme samangqamuzana, ukuncibilikiswa kwamanzi, ukulawulwa kwesisindo se-molecular kanye nokuguqulwa okusebenzayo okusebenzayo.

I-Pam kanye nezinto zayo zokutholwa kwayo zingasetshenziswa njengezinto ezisebenzayo ze-flocculants, i-ejenti yokuqina, i-ejenti yokunciphisa, esetshenziswa kabanzi ekusebenzeni kwamanzi, ekwenzeni iphepha, amalahle, amalahle, amalahle, imikhakha yezimboni.

Ngamanzi angaphansi komhlaba, amanzi angaphezulu komhlaba kanye nokukhucululwa kwendle, ukungcola kanye nokungcola okuvame ukuba khona njengezinhlayiya eziningi ezincanyana kakhulu ukuthi zihlale ngaphansi kwamandla adonsela phansi. Ngenxa yokuthi i-sedimentation yemvelo yehluleka ukufeza izidingo, ngosizo lwamakhemikhali asheshisa ukukhokhelwa kwezobuchwepheshe kusetshenziselwe ukukhiqizwa. Isibonelo, i-pam molecule imunca ngezinhlayiya eziningana futhi yenze i-floc enkulu, ngakho-ke, ukukhokhelwa kwezinhlayiya kuyasheshiswa.

Uma kuqhathaniswa ne-inorganic flocculant, uPam unezinzuzo ezibalulekile: Izinhlobo eziningi zezimo ezahlukahlukene, ukusebenza kahle okuphezulu, umthamo omncane, okulula okwenziwe, ukwelashwa okulula. Lokhu kwenza kube yi-flocculant enhle kakhulu.

Imayelana nomthamo we-inorganic coagulant 1/30 kuya ku-1/200.

UPam uthengiswa ngamafomu amabili aphambili: i-powder kanye ne-emulsion.

I-Powder Pam kulula ukuyihambisa, kepha ayikho lula ukuyisebenzisa (amadivayisi wokudedela ayadingeka), ngenkathi i-emulsion akulula ukuthutha futhi inempilo emifushane yokugcina.

UPam une-soubity enkulu emanzini, kepha ancibilika kancane. Ukudumba kubiza amahora amaningi noma ubusuku bonke. Ukuxubana okuhle kwemishini kuzosiza ukuqeda uPam. Njalo engeza kancane kancane uPam ukushukumisa amanzi - hhayi amanzi kuPam.

Ukushisa kungandisa kancane isilinganiso sokuchithwa, kepha izinga lokushisa akufanele lidlule ku-60 ° C.

Ukuhlushwa okuphezulu kakhulu kwe-polymer solution kungu-0,5%, ukugcwala kwe-pam yamangqamuzana aphansi kungalungiswa ku-1% noma ngaphezulu.

Isixazululo se-PAM esilungiselelwe kufanele sisetshenziswe ezinsukwini eziningana, ngaphandle kwalokho ukusebenza kwe-floccation kuzothinteka.
