Mumamiriro ezvinhu emazuva ano, matambudziko emasuweji anokonzerwa nekuvandudzwa kwemaindasitiri akanyatsogadziriswa zvakanaka munyika nekune dzimwe nyika. Kutaura nezve izvi, tinofanira kutaura mamiriro e decolorizing flocculants mukurapa kwemvura. Chaizvoizvo, tsvina inogadzirwa nemaindasitiri mazhinji inoda kushandisa decolorizing flocculants. Yixing Yakachena Mvura inokuzivisa iwe kune ruzivo rwakakodzera uye mashandisiro mundima dzakasiyana.
Yakasiyana-siyana polymer decolorizing flocculants inoshandiswa zvakanyanya mumunda wemvura yemaindasitiri uye sewage kurapwa kunze kwenyika, pakati peiyo polyacrylamide (PAM) ndiyo mhando huru ye decolorizing flocculant. Kana ichienzaniswa neyechinyakare inorganic munyu flocculants, PAM, serudzi rutsva rwemvura yekurapa mumiririri, ine zvakawanda zvakanakira: nyore uye nyore kushandisa, flocculation mhedzisiro inokwirisa kakawanda kupfuura yechinyakare inorganic munyu decolorizing flocculants; kukurumidza flocculation uye sedimentation kumhanya, yakakwirira sludge dewatering kunyatsoshanda; yakakosha kurapwa maitiro pane mamwe masewage; midziyo iri nyore inodiwa, diki tsoka; mutengo wakaderera wekurapa; tsvina inogona kushandiswa zvakare uye kushandiswa zvakare, nezvimwe.
Kushandiswa kwePAM decolorizing flocculant munzvimbo dzakasiyana dzekushandisa:
1. Kushandisa muindasitiri yekugadzira mapepa
Kushandisa yakakwira molecular uremu PAM se decolorizing flocculant inogona kuwedzera mvura inonaya ye pigment nezvimwe zvinhu mumvura chena uye kuderedza kurasikirwa kwavo. Kuwedzera 0.25 ~ 0.5% PAM kune pulp kunogona kuwedzera sedimentation rate ye pulp ne 40 ~ 80 nguva, kuderedza zvinhu zvakasimba mumvura chena ne 66%, kuwedzera madota emapepa, kuwedzera chiyero chekuchengetedza kwemavara sevhu chena ne8 ~ 18%, uye kuchengetedza 20kg yepulp patani yepepa. Uyezve, mushure mekushandisa PAM, turbidity yemvura chena yakaderedzwa zvakanyanya, kuderedza kusvibiswa kwezvakatipoteredza. Semuyenzaniso, iyo yakamiswa yakasimba yemukaka chena pulp tsvina ine pH=6.8 i3000ppm. Mushure mekurapwa nePAM ine hydrolysis degree ye5 ~ 10%, molecular huremu hwe5.5 ~ 10 miriyoni, uye 500ppm yealuminium sulfate, mvura chena inogona kushandurwa kuita mvura isina ruvara uye yakajeka, uye iyo yakamiswa yakaoma inoderedzwa kusvika pazasi 50ppm.
2. Kushandiswa kwe decolorizing flocculants mukurapa kwemvura
①Anti-scaling uye descaling
Mumvura yeindasitiri uye kuchenesa kwetsvina, mvura yakasviba inofanira kutanga yajekeswa. PAM decolorizing flocculants uye inorganic coagulants inowanzoshandiswa pamwe chete, iyo inogona kuderedza zvakanyanya kushandiswa kweinorganic coagulants, kudzivirira kuvharika kwemidziyo uye kuora nekuda kwekushandisa zvakanyanya inorganic coagulants, uye kudzivirira kuumbwa kwechiyero. 37.5 zvikamu zvePAM zvine huremu hwema molecular pasi pe 1 miriyoni uye 50 zvikamu zve sodium tripolyphosphate zvinoshandiswa kuumba scale inhibitor, iyo inogona kudzivirira chiyero chekupisa kwakanyanyisa kupisa.
②Kurapa kwesuweji yeindasitiri
3. Kushandiswa kwe decolorizing flocculants mukurapwa kwemvura yakasviba muindasitiri yeshuga
Muto wenzimbe unobviswa muchitsikiro nemafekitari eshuga unowanzo vhiringika uye maumbirwo awo akaomawo. Kuti muwane muto wakachena wenzimbe, zvinojekesa makemikari zvinoda kuwedzerwa. Kare, inorganic decolorizing flocculants yaiwanzo shandiswa, asi nekuvandudzwa kweindasitiri yeshuga, inorganic decolorizing flocculants haichakwanise kuzadzisa zvinodiwa zvekugadzira. Mumakore achangopfuura, kushandiswa kwePAM muindasitiri yeshuga kunogona kuwedzera iyo sedimentation rate ne20 nguva.
Muchidimbu, patinosarudza polyacrylamide PAM decolorization flocculant maererano nemamiriro chaiwo, tinofanira kuisarudza maererano nemamiriro akasiyana-siyana ekushandisa uye mamiriro. Naizvozvo, kusarudzwa kwepolyacrylamide kwakakoshawo.
Kana iwe uchida zvigadzirwa zvedu, ndapota inzwa wakasunungukataura nesu!
