Miti yemakemikari inobata sei mvura yetsvina?

Pane nzira nhatu huru:

1. Chemical nzira

Zvichitaurwa zviri nyore, zvinoreva kuwedzera makemikari ejenti kumvura yakasviba kuti tsvina iri mukati iite uye ibviswe nyore.

Coagulation nzira:TIyo inoshanda musimboti weiyo coagulation nzira ndeyekuwedzera makemikari ejenti kumvura, zvichiita kuti zvidimbu zvakaturikwa zviunganidzwe uye zvigadzire ma flocs makuru, uye obva agara pasi negiravhiti. Iyi nzira inogona kunyatsobvisa chromaticity, mabhakitiriya, uye imwe organic zvinhu kubva mumvura. Nekudaro, maitiro ayo ekurapa pazvinhu zvakanyungudika zvachose mumvura ane mashoma, uye maitiro ekurapa anokanganiswa nyore nekushanduka kwekushisa kwemvura uye pH kukosha.

Oxidation nzira:Ukuimba maoxidants (akadai seklorini, ozone) kuodza zvinhu zvine chepfu kuita zvisingakuvadzi. Ozone ine mhedzisiro yakanaka uye haina kusvibiswa kwechipiri, asi mutengo wakakwira; Chlorine inowanzoshandiswa uye yakakodzera kurapa tsvina ine phenol uye cyanide; Mhepo oxidation mhedzisiro ishoma uye inowanzo shandiswa mumvura yetsvina umo zvinosvibisa zviri nyore oxidized.

Electrochemical method: Magetsi anoiswa kubvumira zvinosvibisa kuita pane electrode pamusoro kuti zvibviswe, uye dzimwe nguva sodium chloride inowedzerwa kuwedzera mhedzisiro. Iyi nzira ine maitiro akanaka ekugadzirisa, asi kukanganisa kwayo kunoonekawo: kune rumwe rutivi, inoshandisa magetsi akawanda uye ine mari yakawanda yekushandisa; Kune rumwe rutivi, mamwe maitiro emativi anogonawo kuitika panguva yekuita, zvichiita kuti kusvibiswa kwechipiri.

 

2. Muviri Nzira

Kuparadzanisa tsvina yakasimba kubva mumvura kuburikidza nemaitiro emuviri.

Nzira yekusefa inoshandisa sefa midhiya ine micropores (senge microporous mafirita) kubata yakaturikwa yakaoma mumvura.

Mutemo wekuita sedimentation ndewekushandisa simba rinokwevera zvinhu pasi kubvumira zvidimbu zvinorema zvakaturikwa mutsvina kuti zvigare pasi pemvura.

Nzira yekufambisa mhepo inopinza huwandu hukuru hwematuru madiki mumvura, zvichiita kuti anamate kune twutsvina twunhu uye kugadzira muviri unoyangarara une density yakazara yakaderera pane mvura. Inobva yasimuka kumvura nebuoyancy uye inobviswa nekukwesha midziyo.

Idzi nzira dziri nyore uye dziri nyore kubata, asi hadzigoni kubvisa zvinosvibisa zvakanyungudutswa mumvura uye dzine zvisingakwanisi mukushandisa kwavo.

 

3. Photocatalytic oxidation teknolojia

Nokushandisa ultraviolet chiedza uye oxidizing agents (zvakadai sehydrogen peroxide), zvakaoma kuodza zvinosvibisa (zvakadai sepolychlorinated biphenyls) zvinogona kuparadzwa zvachose.

Pane nzira inodaidzwa kuti 'photocatalytic Fenton', inogona kukurumidza kuburitsa huwandu hwakawanda hwezvinhu zvinoshanda uye nekunyatsoora organic pasi pekuita kwakasanganiswa kwechiedza neayoni.

Imwe nzira ndeyekuwedzera photosensitive semiconductor zvinhu (senge titanium dioxide), izvo zvinogadzira zvakanyanya oxidizing mahara radicals pasi pechiedza chemwenje, ichibvisa zvachose zvinosvibisa kuita zvinhu zvisingakuvadzi zvakaita secarbon dioxide nemvura. Iyi nzira ine mukana mukuru wekurapa recalcitrant zvinosvibisa.
