Kusvibiswa kwemhepo nemvura kunoramba kuri pakati pezvinonyanya kunetsa pasi rose, zvichiisa nharaunda dzakakosha, cheni dzechikafu, uye nharaunda inodiwa kuhupenyu hwevanhu munjodzi.
Kusvibiswa kwemvura kunowanzobva muheavy metal ions, refractory organic pollutants, uye mabhakitiriya - chepfu, inokuvadza inosvibisa kubva mumaindasitiri nemarara emvura maitiro ayo asingaori ega.Nyaya iyi inowedzerwa ne eutrophication yemitumbi yemvura izvo zvinogona kukonzera mamiriro akanaka ekuti huwandu hukuru hwebhakitiriya hubereke, huchiwedzera kusvibisa nekukanganisa kunaka kwemvura.
Kusvibiswa kwemweya kunonyanya kuumbwa nemhepo inopisa (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), uye carbon dioxide (CO).2) - zvinosvibisa izvo zvinonyanya kukonzerwa nekutsva kwemafuta efossil.Mhedzisiro yeCO2se greenhouse gasi rave rakanyorwa zvakanyanya, nehuwandu hwakakosha hweCO2kukanganisa zvakanyanya mamiriro ekunze ePasi.
Yakasiyana matekinoroji uye maitiro akagadzirwa kuitira kupindura kune idzi nyaya, zvinosanganisira activated kabhoni adsorption, ultrafiltration, uye advanced oxidation maitiro (AOPs) achivavarira kugadzirisa nyaya dzekusvibiswa kwemvura.
Kubva kuVOCs adsorption system, iwe uchaona kuti Columnar activated kabhoni chikamu chakakosha uye chakakurumbira chinoshandiswa paVOCs kurapwa masisitimu senge inodhura-inoshanda adsorbent media.
Akabatidzwa kabhoni, mukushandiswa kwakapararira kwemaindasitiri kubva pakupera kweHondo Yenyika I, yaive pakati pemakore ekuma1970 sarudzo yakasarudzika yekudzora kusvibiswa kwemhepo kweVOCs nekuda kwekusarudza kwayo mukubvisa mhute kubva kune gasi hova kunyangwe paine mvura.
Iyo yakajairwa kabhoni-bed adsorption system-imwe inotsamira pakuvandudzwa kwechikwata-inogona kuve nzira inoshanda yekudzoreredza zvinonyungudutsa nekuda kwehupfumi hwavo.Adsorption inoitika apo mhute inonyungudutsa inosangana nekabhoni mubhedha uye inounganidzwa pane porous activated carbon surface.
Carbon-bed adsorption inoshanda mukuita solvent-recovery mashandiro pane solvent concentrations pamusoro pe700 ppmv.Nekuda kwezvinoda kufefetera uye macode emoto, tsika yakajairika yanga iri yekuchengeta kunyungudika kuri pasi pe25% yemuganho wepasi unoputika (LEL).
