Kugadziriswa kwehuwandu hwekushandiswa kwe anionic polyacrylamide

Anionic polyacrylamide inonyanya kushandiswa kusimbisa kuyerera kwetsvina, ine hunhu hwepolymer electrolyte mune neutral uye alkaline medium, inonzwa electrolytes yemunyu, uye maion esimbi anodhura anogona kusanganiswa kuita gel isinganyungudike, iyo inonyanya kushandiswa pakugadzira mvura yemumba, kugadzirisa tsvina yemumaindasitiri nemaguta, uye inogona kushandiswawo pakuderedza mvura kubva mutsvina.

Nzvimbo nhatu huru dzekushandisa anionic polyacrylamide:

Muindasitiri yekugadzira zvinhu zvesimbi, inoshandiswa kuchenesa mvura yekugeza gasi muchoto chakavhurika, kucheneswa kwemvura yakasviba muzvifekitori zvesimbi yeupfu nezvinogadzirwa zvekutsvaira, kucheneswa kweelectrolytes uye kucheneswa kwemvura yakasviba yemagetsi.

Mukuchera, inoshandiswa pakujekesa mvura yekuwachisa marasha uye kuyerera kwemvura inoyerera, kusvina marasha akachena, kushaya mvura kubva mumatope (slag), kujekesa masero emvura inoyerera, kusimba kwemvura inoyerera nekusefa, kujekesa mvura inoyerera nekusefa, kujekesa fluid ye potassium alkali hot melt uye flotation, kujekesa fluorite ne barite flotation, brine isina kubikwa yekugadzirisa munyu, kujekesa sludge dehydration uye phosphate mine recovery water treatment.

Mukugadzirisa mvura yakasviba mumaguta nemaindasitiri, inoshandiswa kunatsiridza kubviswa kwemvura yakasviba yakamiswa, BOD nephosphate mumvura yakasviba. Nekuwedzera 0.25mg/L hydrolyzed polyacrylamide mutangi rekutanga remvura yakasviba, mwero wekubvisa zvinhu zvakamiswa neBOD unogona kuwedzerwa kusvika 66% ne23%, zvichiteerana. Nekuwedzera 0.3mg/L anionic polyacrylamide mutangi rechipiri rekuchenesa mvura yakasviba, mwero wekubvisa zvinhu zvakamiswa neBOD unogona kuwedzerwa kusvika 87% ne91%, zvichiteerana, uye phosphorus removal effect inogona kuwedzerwa kubva pa35% kusvika 91%. Mukurapa mvura yekunwa nemvura yakasviba yemumba, inoshandiswa pakujekesa pamusoro, kujekesa mvura yakasviba inosukwa uye kugadzirisa filtrate.

Kunyunguduka kwekugadzirira anionic polyacrylamide kunounzwa:

1, inoshandiswa mukugara kwetsvina, chiyero chinokurudzirwa che 0.1%

2, tanga wasasa upfu zvakaenzana mumvura yepombi, wobva wakurunga nekumhanya kwepakati pe40-60 RPM kuti polymer inyungudike zvizere mumvura isati yawedzerwa.

3, Munguva yekuedza, tora mvura yakasviba 100ml, wedzera 10% polyacrylamide solution, wobva wakurunga zvishoma nezvishoma, shandisa sirinji kuwedzera zvishoma nezvishoma PAM solution, 0.5ml nguva imwe neimwe, zvichienderana nehukuru hweruva re alum rakagadzirwa uye kuva pedyo kwe flocculant, kujeka kwe supernitant, mwero we sedimentation, chiyero chekuona mushonga wakakodzera.
