Munyaya yekuchenesa mvura, kutsvaga mvura yekunwa yakachena uye yakachena ndiko kwakakosha. Pakati pezvishandiso zvakawanda zviripo zvebasa iri,polyacrylamide(PAM), inozivikanwawo se coagulant, inomira pachena seyakasiyana-siyana uye inoshanda mumiririri. Kushandiswa kwaro muhutano hwekurapa kunovimbisa kubviswa kwekusvibiswa uye kusvibiswa, nokudaro kunowedzera kunaka kwemvura yekunwa. Ichi chinyorwa chinoongorora mashandisirwo akasiyana-siyana epolyacrylamide mukurapa kwemvura yekunwa, achijekesa basa rayo sechinhu chakakosha mukucheneswa.
1. Coagulationuye Flocculation
Imwe yemashandisirwo ekutanga epolyacrylamide mukurapa kwemvura yekunwa iri mukuita coagulation uye flocculation. Kubatana kunosanganisira kudzikamisa kwezvikamu zvecolloidal kuburikidza nekuwedzera kwemakemikari, kufambisa kuunganidzwa kwavo. polyacrylamide inobatsira mukuita uku nekudzikamisa mhosva isina kunaka pazvimedu zvakamiswa, zvichisimudzira kuunganidzwa kwavo kuita maflocs makuru, anogadzika. Zvadaro, flocculation inovimbisa kuumbwa kwemahombe uye denser flocs, iyo inogona kubviswa nyore nyore kuburikidza ne sedimentation kana filtration maitiro.
2. Kuwedzerwa Kubviswa Kwezvinosvibisa
polyacrylamide inokwidziridza kugona kwekubvisa kwezvakasiyana zvinosvibisa zviri mumvura yekunwa. Nekuita kuti kuumbwa kwema flocs makuru, inovandudza sedimentation uye filtration maitiro, zvichiita kuti kubviswa kwakanaka kwezvakamiswa zvakasimba, organic matter, uye microorganisms. Pamusoro pezvo, PAM inobatsira mukubvisa simbi inorema, senge lead uye arsenic, nekugadzira macomplexes ane maion aya, nekudaro kudzivirira kupararira kwavo zvakare mumvura yakabikwa.
3. Kuderedza Turbidity
Turbidity, inokonzerwa nezvimedu zvakaturikwa mumvura, haingokanganisa kunaka kwemvura yekunwa chete asiwo inoshanda sechiratidziro chemhando yemvura. polyacrylamide inonyatso kudzikisa turbidity nekusimudzira kuunganidzwa kwezvimedu zvakanaka muzvikamu zvakakura, izvo zvinogara nekukurumidza. Izvi zvinoguma nemvura yekunwa yakajeka uye inoyevedza, inosangana nezvinodiwa nemitemo uye zvinotarisirwa nevatengi.
Mukupedzisa, polyacrylamide (PAM) inoita basa rakakosha mukurapa kwemvura yekunwa, ichipa akawanda mabhenefiti maererano neCoagulation, kubviswa kwetsvina, kuderedza turbidity, kubvisa algae, uye pH kugadzirisa. Hunhu hwayo hwakasiyana-siyana uye kushanda kwayo kunoita kuti ive chishandiso chakakosha chezvirimwa zvekuchenesa mvura zvinovavarira kupa mvura yekunwa yakachena, yakachengeteka, uye inoyevedza kuvatengi. Sezvo kufambira mberi mune tekinoroji yekurapa mvura kuri kuramba kuchishanduka, polyacrylamide yagadzirira kuramba iri dombo repakona mukutsvaga kwekutonga kwemvura kwakasimba uye kuchengetedzwa kwehutano hweveruzhinji.
