Anionic polyacrylamide inonyanya kushandiswa kusimbisa flocculation yetsvina, ine hunhu hwepolymer electrolyte mune kwayakarerekera uye alkaline svikiro, inonzwira munyu electrolytes, uye mutengo wepamusoro simbi ions inogona kuchinjika-yakabatanidzwa mune insoluble gel, iyo inonyanya kushandiswa kugadzirwa mudzimba. mvura, maindasitiri uye maguta etsvina kurapwa, uye anogona zvakare kushandiswa inorganic sludge dehydration.
Nzvimbo nhatu huru dzekushandisa dzeanionic polyacrylamide:
Muindasitiri yekugadzira uye simbi yekugadzira, inoshandiswa kucheneswa kwemvura yekugezesa gasi muchoto chakavhurika, kujekeswa kwemvura yakaraswa mupowder metallurgy zvidyarwa uye pickling zvidyarwa, kucheneswa kwe electrolytes uye kujekeswa kwe electroplating tsvina yemvura.
Mumigodhi, inoshandiswa kujekesa marasha ekugezesa mvura kujekesa uye kutenderera miswe, kuchena marasha kusefa, tailings (slag) kupera mvura mumuviri, flotation tailings kujekeswa, concentrate thickening uye kusefa, potassium alkali inopisa kunyunguduka uye flotation kugadzirisa fluid kujekesa, fluorite uye barite flotation tailings. , mbishi brine yekugadzira munyu, sludge dehydration kujekeswa uye phosphate mine kudzoreredza mvura kurapwa.
Mumadhorobha uye mumaindasitiri emarara emarara, anoshandiswa kuvandudza kubviswa kwezvakaremerwa solids, BOD uye phosphate mumvura yetsvina.Nekuwedzera 0.25mg/L hydrolyzed polyacrylamide kune yekutanga wastewater sedimentation tank, kubviswa kwemitengo yakamiswa uye BOD inogona kuwedzerwa kusvika 66% uye 23% zvichiteerana.Nekuwedzera 0.3mg/L anionic polyacrylamide kune yechipiri tsvina yemvura yekuchenesa sedimentation tank, kubviswa kwechinhu chakambomiswa uye BOD inogona kuwedzerwa kusvika 87% uye 91%, zvichiteerana, uye phosphorus yekubvisa mhedzisiro inogona kuwedzerwa kubva pa35% kusvika 91%. .Mukurapa kwemvura yekunwa uye tsvina yemumba, inoshandiswa pakujekesa pamusoro, kujekeswa kwekutsvaira mvura yetsvina uye kugadzirisa kwefiltrate.
Iyo solubility yeanionic polyacrylamide kugadzirira inounzwa:
1, inoshandiswa mukugadzirisa tsvina, iyo yakakurudzirwa reshiyo yehuwandu hwe0.1%
2, tanga wamwaya hupfu mumvura yepombi zvakaenzana, uye kurunga nepakati kumhanya kwe40-60 RPM kuita kuti polima inyungudiswe mumvura isati yawedzerwa.
3, Panguva yekuedza, tora 100ml mvura yetsvina, wedzera 10% polyacrylamide mhinduro, uye zvishoma nezvishoma simbisa, shandisa sirinji kuti zvishoma nezvishoma uwedzere mhinduro yePAM, 0.5ml nguva imwe neimwe, zvichienderana nehukuru hwemaruva anogadzirwa alum uye kuswedera kweiyo flocculant, kujeka kweiyo supernitant, iyo sedimentation rate, muyero wekuona mumiriri akakodzera.
