Ndezvipi zvinowanzoitwa cationic flocculants?

Kugadziriswa kwemvura chinhu chakakosha chekutonga kwezvakatipoteredza, kuve nechokwadi chekuti mvura yakachengeteka pakushandisa uye kushandiswa kwemaindasitiri. Chimwe chezvinhu zvinonyanya kukosha pakuita uku ndiko kushandiswa kwemiti inonzi flocculant—makemikari anokurudzira kuunganidzwa kwezvikamu zvakaturikwa kuita zvisumbu zvihombe, kana kuti zvidimbu, izvo zvinozogona kubviswa nyore nyore mumvura. Pakati pemhando dzakasiyana-siyana dze flocculants, cationic flocculants inonyanya kushanda nekuda kwekutengesa kwavo kwakanaka, iyo inopindirana zvakasimba nemafuta asina kunaka anowanzowanikwa mumvura yakasviba. Ichi chinyorwa chinoongorora akajairika cationic flocculants anoshandiswa mukurapa kwemvura uye mashandisiro avo.

Cationic Polyacrylamides(CPAM)

Cationic Polyacrylamides, ari pakati peanonyanya kushandiswa flocculants muindasitiri yekuchenesa mvura. Kune vashandisi vazhinji, CPAM isarudzo yavo iri nani. Aya mapolymers ane acrylamide subunits, iyo inogona kugadzirwa kuti ibatanidze cationic inoshanda mapoka. Iko kuita kwakasiyana-siyana kweCationic polyacrylamides kuri muhuremu hwawo hunochinjika uye huremu hwechaji, zvichivabvumira kuti vagadziriswe kune chaiwo maapplication. C-PAMs inonyanya kushanda mukurapa tsvina yeindasitiri uye sludge dewatering nekuda kwekukwirira kwavo kuyerera uye kuderera kwedosi zvinodiwa.

Poly (diallyldimethylammonium chloride) (PolyDADMAC)

PolyDADMAC inoshandiswa zvakanyanya cationic flocculant inozivikanwa nekukwira kwayo kwechaji density uye kugona mumagadzirirwo emvura. Iyi polymer inonyanya kushanda mukuita coagulation uye flocculation, zvichiita kuti ive sarudzo yakakurumbira yekurapa mvura yekunwa, tsvina, uye tsvina yemumaindasitiri. PolyDADMAC inoshanda zvakanaka pamwe chete nemamwe ma flocculants uye coagulants, inosimudzira iyo yese kurapwa maitiro nekupa yakasimba nzira yekuunganidza particle uye kubvisa.

Polyamines(PA)

Polyamines ndechimwe chikamu che cationic flocculants chinowanzoshandiswa mukurapa kwemvura. Mishonga iyi, iyo inosanganisira poly(dimethylamine-co-epichlorohydrin) uye zvimiro zvakafanana, zvinoratidzira yakasimba cationic charge density, zvichiita kuti zvive zvakanyanya kushanda pakubvisa zvimedu zvinopomerwa zvisina kunaka. Polyamines inonyanya kukosha mukujekesa kwemvura yakasvibirira, kubviswa kwezvinhu zvehupenyu, uye kurapwa kwemhando dzakasiyana dzemaindasitiri. Kukwanisa kwavo kuumba flocs dzakaonda kunoguma nekukurumidza kugadzirisa nguva uye nekunatsiridza kujeka kwemvura inocheneswa.

Zvikumbiro uye Zvakanakira

Cationic flocculants inoita basa rakakosha mumhando dzakasiyana dzemashandisirwo ekuchenesa mvura, kubva kumvura yakaraswa nekanzuru uye kucheneswa kwemvura yekunwa kuenda kumaindasitiri emvura inoyerera. Mukana wavo wekutanga uri mukukwanisa kwavo kudzikamisa zvimedu zvisina kunaka, zvichitungamira kukurumidza uye nekuita floc kuumbwa. Izvi zvinoguma nekujeka kwakagadziridzwa, kuderedzwa kwemhepo, uye kuwedzera kunaka kwemvura. Pamusoro pezvo, cationic flocculants inowanzoshandiswa pamwe chete nemamwe makemikari ekurapa, senge coagulants, kukwidziridza maitiro ekurapa uye kuwana anodiwa emhando yemvura.

Iko kushandiswa kwe cationic flocculants kwakakosha kune yazvino nzira yekurapa mvura, ichipa inoshanda uye yakavimbika mhinduro dzekuunganidza uye kubvisa. Polyacrylamides, polyamines, PolyDADMAC inomiririra mamwe akajairika uye anoshanda cationic flocculants aripo nhasi. Kuita kwavo kwakasiyana-siyana, kushanda nesimba, uye kuchinjika zvinovaita maturusi akakosha mukuona kuwanikwa kwemvura yakachena uye isina njodzi yekushandisa kwakasiyana.

Ehe, kusarudzwa kweflocculant kunoenderanawo nemushandisi maitiro ekushandisa, kuumbwa kwezvinhu, nharaunda, nezvimwe. Iyo chigadzirwa chekushandisa chinofanirwa kuteverwa.
