Miti yemakemikari inorapa sei mvura yakasviba?

Kune nzira nhatu huru:

1. Nzira yemakemikari

Zvichitaurwa zviri nyore, zvinoreva kuwedzera mishonga inouraya tsvina mumvura yakasviba kuti iite kuti tsvina iri mukati ikwanise kupindirana uye ibviswe zviri nyore.

Nzira yekubatanidza：TNzira inoshanda yekubatanidza makemikari ndeyekuwedzera makemikari mumvura, zvichiita kuti zvidimbu zvidiki zvakasungirirwa zviungane uye zvigadzire maflocs makuru, uye zvobva zvagadzika pasi negiravhiti. Nzira iyi inogona kubvisa chromaticity, mabhakitiriya, nezvimwe zvinhu zvipenyu mumvura zvinobudirira. Zvisinei, mhedzisiro yayo pakurapa zvinhu zvakanyungudutswa mumvura yakaganhurirwa, uye mhedzisiro yekurapa inokanganiswa nyore nyore nekuchinja-chinja kwekushisa kwemvura uye pH kukosha.

Nzira yekubvisa oxidation:UZvinokonzera ma oxidant (senge chlorine, ozone) kuti zviparadze zvinhu zvine chepfu kuita zvisina njodzi. Ozone ine mhedzisiro yakanaka uye haina kusvibiswa kwechipiri, asi mutengo wayo wakakwira; Chlorine inowanzoshandiswa uye yakakodzera kurapa mvura yakasviba ine phenol ne cyanide; Mhedzisiro yekuoxidation yemhepo haina kunaka uye inowanzo shandiswa mumvura yakasviba uko kusvibiswa kunooxidation nyore nyore.

Nzira yeElectrochemical: Magetsi anoshandiswa kuti zvinhu zvinosvibisa zvigone kushanda pamusoro peelectrode kuti zvibviswe, uye dzimwe nguva sodium chloride inowedzerwa kuti iwedzere kushanda kwayo. Nzira iyi ine simba rakanaka rekugadzirisa, asi kuipa kwayo kuri pachenawo: kune rumwe rutivi, inoshandisa magetsi akawanda uye ine mari yakawanda yekushanda; Kune rumwe rutivi, zvimwe zvinogona kuitikawo panguva yekushanda, zvichikonzera kusvibiswa kwechipiri.

 

2. Nzira yemuviri

Kusiyanisa tsvina yakaoma nemvura uchishandisa nzira dzepanyama.

Nzira yekusefa inoshandisa nzira yekusefa ine ma micropores (senge ma microporous filters) kuti ibvise zvinhu zvakasimba zvakasungirirwa mumvura.

Mutemo wekuisa mvura mumatope ndewekushandisa simba rinokwevera pasi kuti zvidimbu zvinorema zviri mutsvina zvigare pasi pemvura.

Nzira yekuyangarara kwemhepo inopinza maburi madiki akawanda mumvura, zvichiita kuti anamire patsvina uye agadzire muviri unoyangarara une huwandu hwakaderera pane hwemvura. Wobva wakwira pamusoro pemvura nekuyangarara uye unobviswa nemichina yekukwesha.

Nzira idzi dziri nyore uye dziri nyore kudzora, asi hadzigone kubvisa tsvina yakanyungudutswa mumvura uye dzine miganhu pakushandisa kwadzo.

 

3. Tekinoroji ye oxidation ye photocatalytic

Nekushandisa chiedza cheultraviolet uye zvinhu zvinooxidating agents (zvakaita sehydrogen peroxide), zvinosvibisa zvakaoma kuoresa (zvakaita se polychlorinated biphenyls) zvinogona kuparadzwa zvachose.

Kune nzira inonzi 'photocatalytic Fenton', iyo inogona kugadzira zvinhu zvakawanda zvinoshanda nekukurumidza uye kuora zvinobudirira organic matter kuburikidza nekushanda pamwe chete kwemaion echiedza nesimbi.

Imwe nzira ndeyekuwedzera zvinhu zvinonzwa chiedza (zvakaita setitanium dioxide), izvo zvinogadzira mafree radicals ane oxidizing yakawanda pasi pemwaranzi yechiedza, zvichiparadza zvachose tsvina kuita zvinhu zvisina njodzi zvakaita secarbon dioxide nemvura. Nzira iyi ine mukana mukuru wekurapa tsvina inoramba kushandiswa.
