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 bhakitiriya-chepfu, zvinosvibisa zvinosvibisa kubva mumaindasitiri nemaitiro emvura yetsvina izvo zvisingaori zvega. Nyaya iyi inowedzerwa ne eutrophication yemitumbi yemvura izvo zvinogona kuguma nemamiriro akanaka ekuti huwandu hukuru hwebhakitiriya hubereke, huchiwedzera kusvibisa nekukanganisa kunaka kwemvura.
Kusvibiswa kwemhepo kunonyanya kuumbwa nemhepo inopisa (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), uye carbon dioxide (CO.2) - zvinosvibisa izvo zvinonyanya kukonzerwa nekutsva kwemafuta emafuta. 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.
Yakabatidzwa 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 kune yavo kukosha kwehupfumi. Adsorption inoitika apo mhute inonyungudutsa inosangana nekabhoni mubhedha uye inounganidzwa pane porous activated carbon surface.
Carbon-bed adsorption inoshanda musolvent-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).
