Basa recalcium chloride mukurapa tsvina yetsvina
Chekutanga, nzira yekuchenesa tsvina inosanganisira kurapwa kwemuviri uye kurapwa nemakemikari. Nzira yepanyama ndeyekushandisa zvinhu zvakasiyana-siyana zvefirita zvine saizi dzakasiyana dzemaburi, kushandisa nzira dzekusvina kana dzekuvhara, tsvina iri mumvura haibviswi, chinonyanya kukosha munzira yekusvina ndeyekusvina nekabhoni yakakangwa, nzira yekuvharira ndeyekupfuudza mvura nepafirita, kuitira kuti tsvina yakawanda isapfuure, uye wobva wawana mvura yakachena yakawanda. Pamusoro pezvo, nzira yepanyama inosanganisirawo nzira yekuchenesa, iyo ndeyekurega tsvina ine chikamu chidiki ichiyangarara pamusoro pemvura kuti ibude, kana tsvina ine chikamu chikuru ichidonha pasi pemvura, yozowana. Nzira yemakemikari ndeyekushandisa makemikari akasiyana-siyana kushandura tsvina iri mumvura kuita zvinhu zvisingakuvadzi muviri wemunhu, kana tsvina yakabatana, nzira yekurapa nemakemikari inofanira kushandiswa kwenguva yakareba kuwedzera alum mumvura, mushure mekuunganidzwa kwetsvina mumvura, huwandu hunokura, unogona kushandisa nzira yekusvina kubvisa tsvina.
Calcium chloride, kemikari inowanzoshandiswa mukuchenesa tsvina, chinhu chisina kugadzirwa chine munyu unoumbwa nechlorine necalcium, ionic halide yakajairika. Maion echloride anogona kusvibisa mvura, kuuraya mabhakitiriya anokuvadza, uye kuderedza chepfu mumvura. Maion ecalcium anogona kutsiva ma cation esimbi ari mumvura, kuparadzanisa uye kubvisa maion ane chepfu ane chepfu, uye kubvisa calcium ion inonaya, iyo ine simba rakanaka rekuchenesa nekuuraya utachiona.
Zvinotevera ndezvekuratidza basa recalcium chloride mukurapa tsvina:
1. Calcium chloride inonyungudutswa mumvura mushure mekunge chloride ion yave nesimba rekuuraya utachiona.
2. Maion ecalcium anogona kutsiva macation esimbi ari mutsvina, kunyanya mukugadzirisa mvura yakasviba ine macation esimbi. Kuti kuderedze kukuvara kwezvinhu zvine chepfu zvakanyanya zvemacation esimbi kuchikamu chebiochemical, calcium chloride inoshandiswa mukugadzirisa kwekutanga kubvisa zvinhu izvi zvine chepfu uye zvinokuvadza, izvo zvinoita basa guru. Kana chinhu ichi chikashandiswa muchikamu chetsvina, maion echloride anoita basa rekuuraya mabhakitiriya. Maion ecalcium akaumba calcium hydroxide akadonha uye akabviswa nemvura.
3. Kuderedza PH uye kugadzirisa network yemapaipi etsvina ane acidic kuti pave nenguva yakareba yekushanda kwenetwork yemapaipi.
Maitiro chaiwo ekushandisa: Mushure mekunge mvura yakasviba yaunganidzwa mutangi rinodzora, mvura yakasviba inosimudzwa mutangi rinobatanidza mvura nepombi inosimudza mvura. Tangi rinosanganisa mvura rakakamurwa kuita maitiro maviri ekusanganisa zvishoma nezvishoma nekusanganisa nekukurumidza, zvikamu zvina zvekuita. Mutangi rinosanganisa nekukurumidza, sodium hydroxide inowedzerwa kupombi inoyera mvura kuti igadzirise PH yemvura yakasanganiswa mutangi kusvika pa8, uye polyaluminum chloride inonyungudika mumvura necalcium chloride zvinowedzerwa panguva imwe chete. Nekuwedzera flocculant polyacrylamide mutangi rinosanganisa zvishoma nezvishoma, calcium chloride particles dzakaumbwa dzinobatana kuti dzigadzire floc yakakura; Mushure mekusanganisa mvura, mvura inoyerera ichipinda mutangi re sedimentation, kuburikidza ne natural settlement kuti iwane chinangwa chekuparadzanisa mvura yakasimba, supernatant yaizara kubva pamusoro petangi re sedimentation, uye yozoyerera ichipinda mu secondary coagulation precipitation. Mushure mekuvhiyiwa kwechipiri kwemvura inoyerera nechando, mvura inopfuura nepasefa yebhegi uye sefa yekabhoni inoshandiswa mumudziyo wekudzivirira acid-base uri parutivi rwemuridzi mushure mekupfuura nepanowanikwa ma fluoride ions online, uye ipapo pH value inogadziriswa uye inoburitswa. Mvura isina kukodzera inoburitswa mutangi rekugadzirisa mvura yobva yagadziriswa.
