Municipal tsvina
Mukurapwa kwetsvina yemumba, polyacrylamide inogona kusimudzira kukurumidza kusanganiswa uye kugadzirisa yakamiswa turbidity zvimedu kuti iwane mhedzisiro yekuparadzanisa uye kujekeswa kuburikidza nemagetsi neutralization uye yayo adsorption bhiriji. Inonyanya kushandiswa kugadzirisa flocculation muchikamu chemberi uye sludge dewatering muchikamu chemashure chekugadzirisa tsvina.
Mvura yemarara yeindasitiri
Kana uchiwedzera polyacrylamide kumvura yeakamiswa turbidity particles, inogona kusimudzira kukurumidza kuunganidzwa uye kugadzirisa yakamiswa turbidity zvimedu kuburikidza nemagetsi neutralization uye adsorption bhiriji mhedzisiro yepolymer pachayo, uye kuzadzisa mhedzisiro yekuparadzanisa uye kujekesa, kuitira kuvandudza kushanda zvakanaka uye kuderedza mari yekushandisa.
Indasitiri yekudhinda uye yekudhaya machira
Seye saizi mumiriri uye yekupedzisa mumiriri wejira mushure mekurapwa, polyacrylamide inogona kuburitsa yakapfava, kuunyana-chiratidzo uye mildew inodzivirira yekudzivirira. Nepfuma yayo yakasimba yehygroscopic, inogona kuderedza kutsemuka kweshinda kuruka. Iyo zvakare inodzivirira static magetsi uye murazvo kudzoreredza kwejira. Kana ichishandiswa sedhinda uye dhayi anobatsira, inogona kuwedzera adhesion kukurumidza uye kupenya kwechigadzirwa; Inogona zvakare kushandiswa seisiri-silicon polymer stabilizer yeku bleaching. Pamusoro pezvo, inogona zvakare kushandiswa kucheneswa kwakanaka kwekudhinda machira uye kudhaya tsvina yemvura.
Indasitiri yekugadzira mapepa
Polyacrylamide inoshandiswa zvakanyanya seyamuro yekuchengetedza, sefa yekubatsira uye inoparadzira mukugadzira mapepa. Basa rayo ndere kuvandudza kunaka kwepepa, kunatsiridza kushaya mvura kwemvura kwe slurry, kunatsiridza mwero wekuchengetwa kwemafiber akanaka uye mafirita, kuderedza kushandiswa kwezvinhu zvakasvibiswa uye kusvibiswa kwezvakatipoteredza. Mhedzisiro yekushandiswa kwayo mukugadzira mapepa zvinoenderana neavhareji uremu hwemamorekuru, ionic zvimiro, ionic simba uye basa remamwe macopolymers. Nonionic PAM inonyanya kushandiswa kuvandudza sefa pfuma yepulp, kuwedzera simba repepa rakaoma, kuvandudza chiyero chekuchengetedza fiber uye filler; Anionic copolymer inonyanya kushandiswa seyakaoma uye yakanyorova inosimbisa mumiriri uye mumiriri wepapepa. Iyo cationic copolymer inonyanya kushandiswa pakurapa kwekugadzira mapepa emarara uye filtration aid, uye zvakare ine mhedzisiro yakanaka pakuvandudza mwero wekuchengetedza wekuzadza. Uye zvakare, PAM inoshandiswawo mukugadzira mapepa emarara kurapwa uye fiber kudzoreredza.
Indasitiri yemarasha
Marasha ekugezesa mvura yetsvina, marasha ekugadzira chirimwa chemvura, marasha emagetsi chirimwa pasi achigeza tsvina, nezvimwewo, musanganiswa wemvura nehupfu hwemarasha akatsetseka, hunhu hwayo hukuru huturu hwakanyanya, saizi yakanaka yezvimedu zvakasimba, pamusoro pezvimedu zvakasimba. zvakanyanya kupomerwa zvisina kunaka, simba rinosemesa pakati pechaji imwechete inoita kuti zvikamu izvi zvirambe zvakapararira mumvura, zvakakanganiswa negiravhiti uye Brownian kufamba; Nekuda kwekudyidzana pakati peiyo interface yezvimedu zvakaomesesa mumvura yemarasha slime, zvimiro zvemarasha ekushambidzika kwemvura yakashata zvakanyanya kuoma, izvo zvisiri izvo chete zvimiro zvekumisa, asiwo zvine maitiro ecolloidal. Kuti iite kuti marasha slime mvura iwedzere nekukurumidza muconcentrator, ive nechokwadi chekuti mvura yekugeza inokodzera uye yekumanikidza sefa yemarasha kugadzirwa, uye kuita kuti kugadzirwa kushande uye kushanda kwehupfumi, zvinodikanwa kusarudza iyo yakakodzera flocculant kusimbisa kurapwa kwemarasha slime. mvura. Iyo yakatevedzana yepolymer flocculation dehydrating agent yakagadziridzwa marasha slime dewatering mumarasha ekugezesa chirimwa ine yakanyanya kudzikisa mvura uye iri nyore kushandisa.
Electronic uye electroplating maindasitiri
Iyo inowanzo kurapa maitiro ndeyekugadzirisa pH kukosha kwemvura yakasvibiswa ne sulfuric acid kusvika 2 ~ 3 mutangi rekutanga rekuita, wobva wawedzera kuderedza agent, gadzirisa pH kukosha neNaOH kana Ca (OH) 2 kusvika 7 ~ 8 mune inotevera mhinduro. tangi kugadzira Cr(OH)3 kunaya, wobva wawedzera coagulant kubvisa Cr(OH)3 kunaya.
Simbi kugadzira chirimwa
Inonyanya kushandiswa kuchenesa mvura yakasviba kubva kune flue gasi yeokisijeni inoputika converter, iyo inowanzonzi guruva kubvisa tsvina yemvura yekushandura. Kurapa kwekushandura guruva kubvisa mvura yetsvina muchigayo chesimbi kunofanirwa kutarisisa kurapwa kwezvakarembera zvakamira, tembiricha chiyero uye kugadzikana kwemvura. Iyo coagulation uye kunaya kwemvura kurapwa kwezvinhu zvakamiswa zvinoda kubvisa yakamiswa tsvina yezvimedu zvakakura, uye wozopinda mudhangi resedimentation. Wedzera PH regulator uye polyacrylamide mumugero wakavhurika wetangi rekunyungudutsa kuti uwane iyo yakajairwa flocculation uye sedimentation yezvinhu zvakaturikwa uye chiyero mutangi rekuchera, uye wobva wawedzera sike inhibitor kune tsvina yetangi yekudhaka. Nenzira iyi, haisi kungogadzirisa dambudziko rekujekesa kwemvura yakasvibiswa, asiwo inogadzirisa dambudziko rekugadzikana kwemvura, kuitira kuti uwane hutano huri nani. PAC inowedzerwa mutsvina, uye iyo polymer inotenderedza iyo yakaturikwa chinhu mumvura kuita diki floc. Kana tsvina akawedzera polyacrylamide PAM, kuburikidza zvakasiyana-siyana chisungo kushandirapamwe, zvokuti inova yakasimba kusunga simba guru floc, kuti kunaya. Zvinoenderana nemaitiro, musanganiswa wePAC nePAM une mhedzisiro irinani.
Kemikari chirimwa
Iyo yakakwira chrominance uye zvinosvibisa zvemukati memvura yetsvina zvinonyanya kukonzerwa nekusakwana kwazvinoita mbishi kuita kana huwandu hukuru hwekunyungudutsa hunoshandiswa mukugadzira kupinda mutsvina yemvura. Kune zvinhu zvakawanda zvinoodza, kusaora kwezvipenyu, zvinhu zvakawanda zvine chepfu uye zvinokuvadza, uye zvinhu zvakaoma zvemhando yemvura. The reaction raw materials inowanzova zvinhu zvinonyungudutsa kana macompounds ane ring structure, izvo zvinowedzera kuoma kwekuchenesa mvura. Kusarudza yakakodzera polyacrylamide mhando inogona kuwana zvirinani kurapwa maitiro.
Fekitari yefodya
Kuseri kwedhaka rekushaya mvura, kusarudzwa kwepolyacrylamide flocculant kwakaoma, huwandu hwekuchinja kwemhando yemvura hwakakura, vashandi vehunyanzvi vanofanirwa kutarisisa shanduko yemhando yemvura uye kuita yakakodzera sludge dehydrating agent test kusarudzwa, basa racho uyewo yakakura, iyo yakawanda yakasarudzwa ye cationic polyacrylamide, molecular uremu zvinodiwa zvakanyanyisa, kana mushonga wekuita nekukurumidza uchikurumidza, kushandiswa kuchava nani pane zvinodiwa. zvemidziyo.
Brewery
Kurapa kunowanzo kugamuchirwa tekinoroji yekurapa tekinoroji, senge yakagadziriswa sludge nzira, yakakwira mitoro yebiological filtration nzira uye yekubata oxidation nzira. Kubva pane yazvino nyaya, zvinogona kudzidzwa kuti iyo flocculant inoshandiswa neiyo general brewery inowanzo shandisa yakasimba cationic polyacrylamide, iyo molecular uremu chinodiwa inopfuura 9 miriyoni, mhedzisiro yacho inonyanya kuoneka, iyo dosage ishoma, mutengo wakaderera. , uye mvura yemukati keke yedhaka yakatsikirirwa nesefa zvakare yakaderera.
Pharmaceutical kugadzira chirimwa
Nzira dzokurapa dzinowanzoita sezvinotevera: kurapwa kwepanyama uye kwemakemikari, kurapwa kwemakemikari, kurapwa kwebiochemical uye kusanganiswa kwemaitiro akasiyana-siyana, nezvimwewo. Nzira imwe neimwe yekurapa ine zvayakanakira nezvayakaipira. Parizvino, nzira yekurapa yemhando yemvura inoshandiswa zvakanyanya mukugadzira mishonga yemvura yakasviba pretreatment uye mushure mekurapa, senge aruminiyamu sulfate uye polyferric sulfate inoshandiswa mumagariro echiChinese mushonga wetsvina, nezvimwewo. uye kuwedzera kweakanakisa coagulants.
Fekitari yezvokudya
Nzira yechinyakare ndeyekugadzirisa muviri uye biochemical fermentation, mune biochemical kurapwa maitiro kushandisa polymer flocculant, ita sludge dewatering kurapwa. Mapolymer flocculants anoshandiswa muchikamu chino anowanzo cationic polyacrylamide zvigadzirwa zvine yakakwira ionic degree uye huremu hwemamorekuru.
