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 munzvimbo yekutamisa kwakadzikira pane yezvimwe zvinosvibisa, uye huwandu hweCOD hunenge 5000 ~ 30000mg/L..
Mamiriro makuru emararamiro emarara ndeaya:
①Kune akawanda marudzi ezvinosvibisa zvaka organic, uye mhando yemvura yakaoma (ine akawanda eorganic zvinhu)
②Kuwanda 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.
③Unhu 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:
①Kuwanda kweCOD, BOD, uye ammonia nitrogen (COD inogona kusvika 40,000 ~ 80,000)
②Nguva yekuvirisa yakareba kupfuura yechiteshi chekufambisa.
Mamiriro makuru ekicheni tsvina leachate:
①High 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;
②Mafuta akawandisa emafuta: kunyanya mafuta emhuka nemiriwo, anosvika 3000mg/L mushure mekutanga kurapwa
③High COD, kazhinji nyore ku biodegrade, kusvika ku40,000 kusvika 150,000 mg/L;
④pasi pH (kazhinji inenge 3);⑤munyu wakawanda.
