About Landfill Leachate

Unoziva here? Pamusoro pemarara anoda kurongedzwa, leachate inoraswa inodawo kurongwa.

Zvinoenderana nehunhu hwekurashira marara, inogona kungopatsanurwa kuita: chiteshi chekufambisa marara, leachate yemarara mukicheni, marara emarara, uye leachate yekupisira zvirimwa.

Ndeapi maitiro emhando ina idzi dzemarara emarara?

Hunhu hwechiteshi chekuchinjisa leachate:

1. Pane manyuko makuru emvura yetsvina: zvikuru mvura yetsvina yemumba, inorasa tsvina, uye leachate yemarara.

2. Pamusana penguva pfupi yekugara kwemarara muchiteshi chekutakura marara, kubuda kwe leachate kuduku.

3.Kuwanda kwezvinosvibisa muchiteshi chekufambisa kwakaderera pane kwezvimwe zvinosvibisa, uye kusungirirwa kweCOD kunosvika 5000 ~ 30000mg/L..

Mamiriro makuru emararamiro emarara ndeaya:

Kune akawanda marudzi ezvinosvibisa zvaka organic, uye mhando yemvura yakaoma (ine akawanda eorganic zvinhu)

Kuwanda kwezvinosvibisa uye kwakasiyana-siyana shanduko (yekutanga BOD uye COD kutariswa ndiko kwakanyanya, kusvika makumi ezviuru emamirigiramu parita, pH kukosha kuri kana kuderera zvishoma pane 7, B/C iri pakati pe0.5-0.6, uye iyo biochemical properties yakanaka) , kazhinji kutaura, iyo COD, BOD, BOD / COD ratio inoderera ne "zera" remarara, uye alkalinity inowedzera.

Unhu hwemvura uye huwandu hunosiyana zvakanyanya: huwandu hwemvura hunosiyana zvakanyanya nemwaka (mwaka wekunaya kwemvura zviri pachena kuti wakakura kupfuura mwaka wekupisa); kuumbwa uye kusangana kwezvinosvibisa zvinoshandukawo nemwaka; kuumbwa uye kuwanda kwezvinosvibisa zvinoshanduka nenguva yekuraswa kwemarara.

Hunhu hukuru hwekuraswa kwemarara mumiti yekupisa ndeiyi:

Kuwanda kweCOD, BOD, uye ammonia nitrogen (COD inogona kusvika 40,000 ~ 80,000)

Nguva yekuvirisa yakareba kupfuura yechiteshi chekufambisa.

Mamiriro makuru ekicheni tsvina leachate:

High suspended solids: Maleachate akasiyana ane zvikamu zvakasiyana-siyana zvakasimirirwa zvakasimba mumamiriro ekugadzirisa uye colloidal state, yakakwirira se60,000 kusvika ku120,000 mg / L, ine kupararira kwepamusoro uye yakaoma kuparadzanisa;

Mafuta akawandisa emafuta: kunyanya mafuta emhuka nemiriwo, anosvika 3000mg/L mushure mekutanga kurapwa

High COD, kazhinji nyore ku biodegrade, kusvika ku40,000 kusvika 150,000 mg/L;

yakaderera pH (kazhinji inenge 3);munyu wakawanda.
