Kurapa kwemvura chinhu chakakosha kukosha kwekutonga kwezvakatipoteredza, kuve nechokwadi chekuti mvura yakachengeteka pakushandisa uye kushandiswa kwemaindasitiri. Chimwe chezvinhu zvakakosha mukuita uku ndiko kushandiswa kweanobhururuka-makemikari anokurudzira kusunganidzwa kwezvikamu zvakamiswa kuita masango akakura, kana mafu, izvo zvinogona kubva zvinobviswa zviri nyore kubva mumvura. Pakati pemhando dzakasiyana-siyana dzezvakashata, maCationlic anofudza zvakanyanya kushanda nekuda kwekupomera kwavo kwakanaka, izvo zvinopindirana zvakanyanya neakasarudzika neakashata zvibodzwa zvinowanzowanikwa mumarara. Ichi chinyorwa chinoongorora zvinonyanya kuitika zveCateculants zvinoshandiswa pakurapwa kwemvura uye zvavanoshandisa.
Cationic Polyacrylamities(CPAM)
Chusic Polyacrylamities, ndedzipi pakati penyama dzinoshandiswa zvakanyanya muindasitiri yemvura yekurapa. Kune vashandisi vazhinji, CPAM ndiyo sarudzo yavo iri nani. Idzi polymers ine acrylamide subunits, iyo inogona kuve yakagadziriswa kuti isanganisira mapoka eContics anoshanda. Iko kuwanda kweCatiic Polyacrylamities kunorara mune yavo inoshandurwa suremu uye kubhadharisa density, kuvabvumira kuti vagadziriswe kuti vagadziriswe zvikumbiro. C-pams inonyanya kushanda mukurapa maindasitiri marara uye sludge dewatering nekuda kwekushanda kwavo kwepamusoro uye zvakaderera madhiri.
Poly (Deldallyimethylammonium chloride) (Polydadmac)
Polydadmac iri iyo yakashandiswa zvakanyanya cationculant inozivikanwa neyakawedzera kubhadharisa density uye kushanda kwayo mumvura yekurapa kwemvura. Iyi polymer inonyanya kushanda mukubatana uye maitiro ekurima, ichiita sarudzo yakakurumbira yekurapa mvura yekunwa, makatanwa, uye maindasitiri. Polydadmac anoshanda zvakanaka pamwe chete nevamwe vanofamba nemamwe anowedzera uye anowedzera maitiro ehuremu ekurapa nekupa simba rekurovera kwekukwezva nekubviswa.
Polyamine(PA)
Polyamine ndeimwe chikamu cheCationic inoyerera inowanzo shandiswa mukurapwa kwemvura. Iyi mishonga, iyo inosanganisira poly (dimethylamine-co-epichlorohydrin) uye zvimiro zvakafanana, kuratidzira yakasimba cation conity density, ichiita kuti vabudirire pakurariswa zvisina kurongeka. Polyamine anobatsira zvakanyanya mukujekeswa kwemvura yakasviba, kubviswa kwenyaya yeganda, uye kurapwa kwezvakasiyana maindasitiri. Kugona kwavo kuumba maronda etsiva kunoguma nekukurumidza kugadzirisa nguva uye yakajeka kujekesa kwemvura yakabatwa.
Zvikumbiro nezvakanaka
Cationic inofamba ichitamba basa rakakosha mune dzakasiyana siyana dzezvekurapa kwemvura zvikumbiro, kubva kune yakasviba masvomhu uye kunwa mvura kucheneswa kune maindasitiri ekugadzira. Kubatsira kwavo kwekutanga kuri mukukwanisa kwavo kunyatso tsanangudza zvisina kukodzera kubhadharwa zvishanu, zvichitungamira kukurumidza uye zvakanaka floc fomu. Izvi zvinoguma zvaitika kujekesa kwakavandudzwa, zvakaderedzwa tarisiro, uye kuvandudza huwandu hwemvura. Pamusoro pezvo, maCationlic anofamba anowanzo shandiswa pamwe chete nemamwe makemikari ekurapa, akadai secaluculants, kuti agadzirise maitiro ekurapa uye kuwana hunhu hunodiwa hwemvura.
Iko kushandiswa kweCationic Floculants ndeyekuita kwemazuva ano kurapwa kwemvura maitiro, kupa inoshanda uye yakavimbika mhinduro dzechikamu chekisimusi uye kubvisa. Polyacrylamips, polyamine, polydadmac anomiririra mamwe emamwe maCateculu anowanikwa nhasi. Kubudirira kwavo, kushanda kwavo, uye kushanduka kunovaita kuita zvishandiso zvisingaite mukuona kuwanikwa kwemvura yakachena uye yakachengeteka yemvura yakashandiswa zvakasiyana siyana.
Ehezve, sarudzo yeku fletulutulont zvakare inoenderana neyakaitwa nemushandisi maitiro, kuumbwa, zvakatipoteredza, etc. Chigadzirwa chekushandisa kwechigadzirwa chinofanira kuteverwa.
