Unoziva here? Pamusoro pemarara anoda kurongedzwa, tsvina yemumarara inofanirawo kurongedzwa.
Zvichienderana nehunhu hwe leachate yemarara, inogona kupatsanurwa muzvikamu zviviri: leachate yemarara inoiswa panzvimbo yekuchinjisa marara, leachate yemarara ekicheni, leachate yemarara inoiswa mumarara, uye leachate yemarara inoiswa mumarara muzvirimwa zvinopisa.
Ndezvipi zvinhu zvinoitwa nemarudzi mana aya emarara anorasirwa marara?
Hunhu hwenzvimbo yekuchinjisa chiteshi chekufambisa:
1. Kune nzvimbo dzakawanda dzinowanikwa mvura yakasviba: mvura yakasviba yemumba, mvura yakasviba inoyerera, uye mvura inorasirwa mumarara.
2. Nekuda kwenguva pfupi yekugara kwemarara panzvimbo yekutamisira marara, kubuda kwemarara mudura kushoma.
3.Kuwanda kwezvinosvibisa munzvimbo yekutamisira kwakaderera pane kwezvimwe zvinosvibisa, uye huwandu hweCOD hunosvika 5000~30000mg/L.
Hunhu hukuru hwe leachate yemarara ndeiyi:
①Kune mhando dzakawanda dzezvinosvibisa zvipenyu, uye kunaka kwemvura kwakaoma kunzwisisa (ine zvakawanda zvezvinhu zvipenyu)
②Kuwanda kwezvinosvibisa uye shanduko dzakasiyana-siyana (huwandu hwekutanga hweBOD neCOD hwakanyanya kukwira, kusvika kumakumi ezviuru zvemamirigiramu pa litre, pH kukosha iri pa7 kana kuti pasi zvishoma, B/C iri pakati pe0.5-0.6, uye hunhu hwebiochemical hwakanaka), kazhinji, chiyero cheCOD, BOD, BOD/COD chinoderera ne "zera" remarara, uye alkalinity inowedzera.
③Hunhu hwemvura nehuwandu hwayo zvinosiyana zvikuru: huwandu hwemvura hunosiyana zvikuru nemwaka (mwaka wemvura unobuda pachena kuti wakakura kupfuura mwaka wekusanaya kwemvura); kuumbwa kwemvura inosvibisa uye huwandu hwayo zvinochinjawo nemwaka; kuumbwa kwemvura inosvibisa uye huwandu hwayo zvinochinja nenguva yekurasira marara.
Hunhu hukuru hwe leachate yemarara mumiti inopiswa ndeiyi:
①Kuwanda kweCOD, BOD, uye ammonia nitrogen (COD inogona kusvika 40,000~80,000)
②Nguva yekuvirisa yakareba kupfuura yenzvimbo yekutamisira.
Zvinhu zvikuru zvinoumba tsvina yekicheni:
①Zvinhu zvakasimba zvakamiswa zvakanyanya: Zvinhu zvakasiyana-siyana zvine huwandu hwakasiyana hwezvinhu zvakasimba zvakamiswa mumamiriro ezvinhu anogona kugadziriswa uye mamiriro e colloidal, kusvika pa60,000 kusvika 120,000 mg/L, zvine kupararira kwakanyanya uye zvakaoma kupatsanura;
②Mafuta akawanda: mafuta emhuka nemiriwo, anosvika 3000mg/L mushure mekurapwa kwekutanga
③COD yakakwira, inowanzo nyore kuora, inosvika 40,000 kusvika 150,000 mg/L;
④pH yakaderera (kazhinji inenge 3);⑤munyu wakawanda.
