Sei maflocculant anobvisa ruvara kubva kumaindasitiri akasiyana asingagone kushandiswa achichinjana?

Mazwi akakosha: Kubvisa ruvara rweflocculant, chinhu chinobatsira kubvisa ruvara, mugadziri wechinhu chinobatsira kubvisa ruvara

Mubasa rekuchenesa mvura yakasviba mumaindasitiri,zvinobvisa ruvara rwemaflocculantkuita se "chiremba wemhando yepamusoro yemvura," kunyanya kuongorora nekupa mishonga yemvura yakasviba kubva kumaindasitiri akasiyana. Zvisinei, chiremba uyu ane musimboti: haambo "rapa" kunze kweindasitiri yake. Sei kudhaya nekudhinda zvinhu zvisingashandiswe zvakananga mumafekitori emapepa? Sei mafomura emafekitori ezvekudya asingakwanise kurapa mvura yakasviba inoputirwa nemagetsi? Kumashure kweizvi kune "kodhi yeindasitiri" yekurapa mvura yakasviba mumaindasitiri.

1. "Misiyano yeMajini" yeMarara eMaindasitiri

Mvura yakasviba inobva kumaindasitiri akasiyana yakafanana nevanhu vane marudzi akasiyana eropa, inoda "ropa rinobvisa ruvara rinobvisa ruvara." Semuenzaniso, dhayi nekudhinda mvura yakasviba; ine huwandu hwakawanda hwezvinhu zvakaoma zve organic zvakaita seazo dyes uye reactive dyes. Zvinhu izvi zvinoumba negative charge colloids mumvura, zvichida kuti cationic decolorizing agents dzibvise ruvara uye dzibvise ruvara. Mvura yakasviba yepaper mill inonyanya kuumbwa ne lignin ne cellulose, uye hunhu hwayo hwe colloidal hwakasiyana zvikuru nehwema dyes. Kumanikidza kushandiswa kwe dyeing agents munyaya iyi kwakafanana nekuedza kurapa mapfupa akatyoka nemushonga unotonhora - mhedzisiro yacho ichadzikira zvakanyanya.

Muenzaniso wakajairika imvura yakasviba inogadzirwa nechikafu. Rudzi urwu rwemvura yakasviba rune zvakawanda zvezvinhu zvakasikwa zvakaita semapuroteni nestarch, uye pH yayo inowanzova isina kana acid kana kuti ine acid zvishoma. Kushandisa alkaline dyeing decoloring flocculants hakungokundikani chete kubvisa ruvara rwemvura yakasviba asi kuchaparadzawo tupukanana tunobatsira, zvichikonzera kuparara kwemaitiro ekurapa emuviri anotevera. Izvi zvakafanana nekupa adrenaline zvisirizvo kumurwere ane chirwere cheshuga uchibaya insulin - mhedzisiro yacho haifungidzike.

2. "Kufananidza Kwakarurama" kweMagadzirirwo Ehunyanzvi

pH kukosha ndiyo "chiyero chakanaka" chekusarudza maflocculant anobvisa ruvara. Imwe fekitari yemakemikari yaimboshandisa mushonga unobvisa ruvara kubva mumvura yakasviba inogadzirwa nemagetsi (pH=2) pamvura yakasviba yemishonga (pH=8), zvichikonzera kusashanda kwemushonga wacho zvachose. Izvi zvinodaro nekuti nzvimbo ine acid yakawanda inoora ma cationic agents, nepo nzvimbo ine alkaline inogona kukonzera kunaya kwe anionic decoloring flocculant. Kupisa kwakakosha zvakaenzana. Kushandisa mishonga inodziya zvishoma mumvura yakasviba ine tembiricha yepamusoro (60℃) kubva kuma textile mills kuchaita kuti floc dzakasununguka dzigare zvishoma nezvishoma, sekushandisa chando kubika hot pot - kutyora mitemo yepanyama zvachose.

3. "Nheyo mbiri" dzehupfumi nekuchengetedzwa

Kushandisa mishonga mumaindasitiri akasiyana siyana kunogona kuita sekunge kwakaderera, asi kune njodzi huru. Imwe kambani, mukuyedza kuchengetedza mari, yakashandisa mushonga wedehwe wekugadzira jira remvura rinobvisa ruvara mufekitori yekuchenesa mvura yakasviba muchipatara, zvichikonzera kuburitswa kwesimbi yakawanda uye faindi huru kubva kune vane masimba ekuchengetedza nharaunda. Kunyange zvazvo mishonga yemhando yepamusoro ichidhura zvakanyanya, kuisa mushonga chaiwo kunogona kuderedza kushandiswa ne30%, zvichikonzera kudzikira kwemitengo yese. Chinonyanya kukosha ndechekuti mishonga yakagadzirwa inogona kudzivirira kusvibiswa kwechipiri. Muchina wekugadzira mapepa, mushure mekushandisa mushonga wekugadzira jira unobvisa ruvara, wakasangana neCOD yakawandisa mutsvina yawo, zvichiita kuti uise mari muzvivakwa zvepamusoro zvekurapa, zvichizopedzisira zvapetwa kaviri mitengo yawo.

4. "Zvipingamupinyi Zvakasimba" zveMitemo yeIndasitiri

"Muyero weKusvibisa Mvura weKudhaya Machira neKupedzisa Maindasitiri" unoda pachena kuti kushandiswa kwemishonga yekubvisa ruvara. Izvi hazvisi zvehunyanzvi chete asiwo mutoro wepamutemo. Kambani yekudhaya nekudhinda yakarambidzwa nevakuru vezvekuchengetedza nharaunda nekuda kwekushandisa makemikari akajairika zvisiri pamutemo, zvichikonzera kurasika kweodha. Mishonga yekubvisa ruvara yeindasitiri inowanzo bvumidzwa neISO uye ine mishumo yakazara yekuyedzwa, nepo makemikari akajairika achiwanzo shaya magwaro ekutevedzera mitemo, zvichikonzera njodzi huru.

Hapana mhinduro "inokodzera zvese" yekurapa mvura yakasviba mumaindasitiri; danho rega rega rine nzira yaro yakasiyana. Kubva pakusiyana kwehuwandu uye hunyanzvi kusvika kumari yehupfumi uye zvikwereti zvemutemo, chinhu chimwe nechimwe chinotaura chokwadi chimwe chete: kubvisa ruvara rwezvinhu zvinobva mumaindasitiri akasiyana hazvifanirwe kusanganiswa. Izvi hazvisi nyaya yesarudzo yetekinoroji chete, asiwo nyaya yekuremekedza mitemo yechisikigo uye kuzvipira kune zvakatipoteredza. Mune ramangwana, sezvo kupatsanurwa kwemaindasitiri kuri kuwedzera kunatswa, kugadzirisa nekugadzirisa zvichave tsika yekurapa mvura yakasviba.
