Cov xwm txheej tam sim no ntawm kev hloov pauv khoom pov tseg

Xov xwm tshiab txog kev pov tseg zaub mov

California txoj cai lij choj compost (SB 1383) tau dhau los txij li xyoo 2016 thiab yuav siv rau xyoo 2022. Nws yuav tsis siv txog xyoo 2024 xyoo no. Vermont thiab California twb dhau txoj cai no lawm. Txhawm rau hloov cov khoom noj pov tseg rau hauv roj, tsoomfwv cov chaw haujlwm tau koom tes tsim cov txheej txheem tsim nyog, biogas digesters, thiab cov khoom siv composting, tab sis kev nce qib tseem qeeb.

Rau ib tus neeg ua liaj ua teb hauv Thompson, Conn., nrog cov khoom pov tseg ze ze kaw thiab cov nqi pov tseg pov tseg tau nce, hloov cov khoom noj pov tseg rau hauv lub zog yog qhov muaj yeej-yeej. Ntawm qhov tod tes, cov khoom noj khib nyiab suav txog li 25% ntawm cov khib nyiab hauv zos yuav tsum tau ua. Ntawm qhov tod tes, cov methane tsim los ntawm anaerobic digester yog siv rau cov cua sov hauv zos thiab hluav taws xob. Cov txheej txheem digestate tuaj yeem siv rau thaj av kom nce av fertility. Txawm li cas los xij, tus nqi tsim kho ntawm biogas digesters yog siab thiab tsis tuaj yeem ua tau raws li cov khoom pov tseg hauv zos. Tseem muaj ntau cov khoom noj pov tseg uas yuav tsum tau ua.

Cov khw muag khoom hauv Australia siv lub tshuab ziab khaub ncaws kom evaporate cov dej hauv cov khoom noj pov tseg kom txo qhov hnyav thiab ntim ntawm cov khoom pov tseg, khaws cov khoom noj muaj txiaj ntsig ntau thaum ua kom tsis muaj menyuam thaum kub kub. Cov khoom siv ua tiav yog siv los ua cov khoom siv nuv ntses thiab muab rau cov pas dej ntses uas tsis tuaj yeem noj. Paub txog kev siv peev txheej thaum kho cov khib nyiab tsis zoo.

Txij li thaum lub tswv yim ntawm kev txo cov pa roj carbon monoxide thiab kev tiv thaiv ib puag ncig tau raug npaj, ntau thiab ntau tus neeg tau mloog zoo rau kev pov tseg thiab kev siv cov khoom siv khib nyiab. Nyob rau theem no, raws li cov neeg siv sib txawv, cov kev xav tau sib txawv thiab cov txheej txheem ua tiav, yuav ua li cas xaiv cov khoom noj khoom haus pov tseg uas tsim nyog kom txo tau cov nqi thiab ua kom cov peev txheej rov qab los thiab cov txiaj ntsig kev lag luam tau dhau los ua cov lus nug uas tib neeg xav txog. Ntawm no yog cov lus qhia luv luv ntawm cov txheej txheem kev kho zaub mov tsis zoo tam sim no los muab cov neeg siv khoom siv rau kev xaiv cov khoom siv.

Cov khoom lag luam ntawm cov khoom siv pov tseg cov khoom siv hloov pauv technologies

1.Landfil method

Txoj kev pov tseg ib txwm siv tsuas yog kho cov khib nyiab tsis sib xws. Nws muaj qhov zoo ntawm kev yooj yim thiab tus nqi qis, tab sis qhov tsis zoo yog tias nws nyob hauv ib cheeb tsam loj thiab ua rau cov pa phem thib ob. Tam sim no, cov chaw pov tseg uas twb muaj lawm faus cov khib nyiab los yog cov tshauv tom qab incineration, thiab ua kev kho mob los tiv thaiv. Tom qab cov zaub mov pov tseg yog pov tseg, methane tsim los ntawm anaerobic fermentation yog emissions mus rau saum huab cua, exacerbating lub tsev cog khoom nyhuv. Landfilling tsis pom zoo rau kev pov tseg cov khoom noj.

2.Biological kho tshuab

Cov cuab yeej siv tshuaj lom neeg siv cov kab mob ua kom cov kab mob hauv cov khoom pov tseg hauv cov zaub mov pov tseg thiab hloov mus rau H2O, CO2 thiab cov organic molecular me me kom txo cov khib nyiab thiab tsim cov khoom me me uas tuaj yeem siv los ua biomass organic chiv. Kev kho cov thev naus laus zis muaj xws li composting, aerobic fermentation, anaerobic fermentation, biogas digesters, thiab lwm yam.

Anaerobic fermentation ua haujlwm nyob rau hauv ib puag ncig tag nrho nyob rau hauv cov xwm txheej ntawm anoxia lossis cov pa oxygen tsawg, thiab feem ntau tsim cov methane, uas tuaj yeem siv los ua lub zog huv thiab hlawv los tsim hluav taws xob. Txawm li cas los xij, biogas residue tso tawm tom qab kev zom zaub mov muaj cov ntsiab lus siab ntawm cov organic teeb meem thiab tseem yuav tsum tau ua ntxiv thiab siv ua cov chiv organic.

Daim duab. OWC Food Waste Bio-Dgester cov cuab yeej zoo li thiab sorting platform

Aerobic fermentation thev naus laus zis ua rau cov khib nyiab thiab cov kab mob sib npaug sib npaug thiab tswj cov pa oxygen txaus los ua kom cov kab mob decomposition. Nws muaj cov yam ntxwv ntawm kev ua haujlwm ruaj khov, tus nqi qis, thiab tuaj yeem tsim cov organic chiv zoo substrate. HYHH's OWC Food Waste Bio-Digester siv high-temperature aerobic fermentation technology thiab ntse tswj los xyuas kom meej tias qhov kub thiab txias nyob rau hauv cov cuab yeej yog ruaj khov nyob rau hauv lub high-activity ntau ntawm aerobic microorganisms. Cov xwm txheej kub kub kuj tuaj yeem tua cov kab mob thiab cov qe kab hauv cov khib nyiab.

3. Pub tshuab

Lub khw Australian tau hais ua ntej siv tshuab ziab khaub ncaws-hauv-feed. Kev siv tshuab ziab khaub ncaws yog kom qhuav cov khoom pov tseg ntawm 95 ~ 120 ℃ rau ntau tshaj 2 teev kom txo cov dej noo ntawm cov khoom pov tseg kom tsawg dua 15%. Tsis tas li ntawd, muaj cov txheej txheem pub protein, uas zoo ib yam li kev kho mob lom thiab qhia txog cov kab mob tsim nyog rau hauv cov khib nyiab los hloov cov organic teeb meem rau hauv cov khoom muaj protein. Cov khoom tuaj yeem siv los ua khoom noj los yog nyuj thiab yaj. Txoj kev no yog qhov tsim nyog rau cov xwm txheej uas qhov chaw ntawm cov khoom noj khib nyiab ruaj khov thiab nws cov khoom siv tau yooj yim.

4.Collaborative incineration method

Cov khoom siv pov tseg muaj cov dej ntau, cua sov, thiab tsis yooj yim rau hlawv. Qee cov nroj tsuag incineration muab cov khoom noj uas tau kho ua ntej rau hauv cov khib nyiab hauv nroog hauv qhov kev faib ua feem tsim nyog rau kev sib koom ua ke.

5. Yooj yim hauv tsev compost thoob

Nrog rau kev nkag siab ntawm ib puag ncig kev paub thiab kev nyiam hauv Is Taws Nem, muaj ntau cov ntawv tshaj tawm lossis cov yeeb yaj kiab txog kev ua cov khoom noj hauv tsev pov tseg cov khib nyiab khib nyiab. Simplified composting thev naus laus zis yog siv los rov siv cov khoom noj khoom haus pov tseg hauv tsev, thiab cov khoom siv decomposed tuaj yeem siv rau fertilize zaub hauv vaj. Txawm li cas los xij, vim yog kev xaiv cov kab mob microbial, cov qauv ntawm lub thoob hauv tsev, thiab cov khoom ntawm cov khoom noj khib nyiab nws tus kheej, cov teebmeem sib txawv heev, thiab cov teeb meem xws li tsw ntxhiab tsw, tsis tiav decomposition, thiab lub sij hawm ntev composting yuav tshwm sim.
