Txhua yam uas yog ib zaug ua neej muaj peev xwm ua lwg. Qhov no suav nrog cov zaub mov pov khib nyiab, thiab cov ntaub ntawv uas ua tau los ntawm chaw cia khoom, npaj, ua noj, tuav, muag khoom noj, lossis muab khoom noj. Raws li ntau cov lag luam thiab cov neeg siv khoom tsom rau kev ruaj khov, composting ua lub luag haujlwm tseem ceeb hauv kev txo cov pov tseg thiab cov pa roj carbon. Thaum cov nplooj lwg muaj kev txhawj xeeb, nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm nplooj lwg hauv tsev thiab kev sib sau ua ke.
Muaj Composting
Muaj cov nplooj lwg yog ib qho kev tswj hwm nquag uas tau piav qhia ob qho tib si ib puag ncig, hauv tsawg dua 180 hnub, tib yam li nplooj - xws li nplooj thiab nyom clippings). Cov khoom uas tau lees paub cov khoom lag luam tau ua rau muaj kev cuam tshuam kom tsis txhob cuam tshuam cov txheej txheem sib sau ua ke. Raws li microbes tawg tag nrho thiab lwm cov ntaub ntawv organic, cua sov, dej, carbon dioxide, thiab muaj yas nyob tom qab.
Muaj cov nplooj lwg yog ib qho kev tswj hwm nquag uas yog cov ntsiab lus tseem ceeb tau saib xyuas kom meej thiab ua tiav biodegradation. Composters saib ph, carbon thiab nitrogen ratios, kub, dej noo tshaj plaws los ua kom hloov cov organic pov tseg, thiab kom muaj kev sib tw ua tiav cov khoom noj muaj txiaj ntsig zoo nkauj, thiab kom muaj kev sib tw ua kom tiav rau cov qauv ensodicming.yog li cas los pab kom hloov cov organic zoo, zoo li vaj txiv hmab trimmings thiab sab laug cov khoom noj, deb ntawm av pov tseg. Qhov no yog qhov tseem ceeb uas tsis kho covlo khib nyiab yuav pw thiab tsim cov roj methane. Methane yog ib cov roj teeb nyom uas muaj peev xwm hloov chaw huab cua.
Tsev Nplooj lwg
Tsev nplooj lwg yog cov txheej txheem roj ntsha thaum ib txwm tshwm sim cov kab mob occ occ materials,, cov kab mob thiab qee cov chav ua noj ua ke rau hauv cov av zoo li cov khoom hu ua nplooj lwg hu ua nplooj lwg hu ua compost. Nws yog ib daim ntawv ntawm kev rov ua dua tshiab, ib txoj hauv kev rov qab ua rau cov zaub mov uas xav tau rau cov av. Los ntawm kev sib sau ua noj chav ua noj scraps ibD yard trimmings nyob hauv tsev, koj tuaj yeem txuag qhov chaw nyob tseem ceeb siv los pov tseg cov khoom siv cua no thiab pab txo cov pa hluav taws xob uas hlawv cov khib nyiab. Qhov tseeb, yog tias koj nplooj lwg ntawm kev txuas ntxiv, lub ntim ntawm cov khib nyiab koj tsim tau los ntawm ntau li 25%! Composting yog tswv yim, yooj yim thiab tuaj yeem yooj yim dua thiab tsis tshua kim dua bagging cov ntaub so no thiab coj lawv mus rau qhov chaw nres nkoj lossis chaw nres tsheb.
Los ntawm kev siv cov nplooj lwg koj rov qab cov organic teeb meem thiab cov as-ham rau cov av hauv ib daim ntawv nkag mus rau cov nroj tsuag. Cov teeb meem organic txhim kho cov nroj tsuag kev loj hlob los ntawm kev pab kom cov av nplaum hnyav rau hauv cov av xuab zeb, thiab los ntawm kev ntxiv cov ntaub ntawv tseem ceeb rau ib qho av. Txhim kho koj cov av yog thawj kauj ruam rau kev txhim kho kev noj qab haus huv ntawm koj cov nroj tsuag. Cov nroj tsuag muaj kev noj qab haus huv pab ntxuav peb cov huab cua thiab txuag tau peb cov av. Yog tias koj muaj lub vaj, cov nyom, tsob ntoo, lossis cov thawv planter, koj muaj kev siv rau nplooj lwg.
Qhov sib txawv ntawm kev sib cav sib ceg thiab ua kom tiav tsev
Ob daim ntawv ntawm composting tsim cov khoom noj muaj txiaj ntsig zoo kawg ntawm cov txheej txheem. Muaj cov composting muaj peev xwm txhawb nqa qhov kub thiab qhov ruaj khov ntawm cov nplooj lwg ntau dua.
Ntawm qib yooj yim tshaj plaws, tsev nplooj lwg ua tau los ntawm cov khoom noj muaj txiaj ntsig zoo xws li cov khoom noj muaj txiaj ntsig zoo li cov khoom noj muaj txiaj ntsig zoo li cov khoom noj muaj txiaj ntsig zoo, nplooj ntoo nyom, thiab cov hnab tshuaj yej. Qhov no tshwm sim tshaj ib lub hlis ib txwm nyob hauv qab qaum teb nplooj lwg, lossis lub tsev nplooj lwg hauv tsev. Tab sis, cov xwm txheej thiab qhov kub thiab txias rau tsev ua kom tiav rau cov khoom tu siab.
Qhov ntawd yog qhov chaw peb tig mus rau kev siv composting - ib kauj ruam ib haiv neeg, ze saib xyuas cov txheej txheem ntawm dej, huab cua, nrog rau cov khoom siv roj carbon thiab cov nitrogen-nplua nuj. Muaj ntau hom kev ua lag luam - lawv txhua tus tau ua kom zoo rau txhua kauj ruam ntawm cov txheej txheem decomposition, los ntawm kev tswj cov khoom zoo li cov me me lossis tswj cov kub thiab cov pa oxygen. Cov kev ntsuas no kom ua kom cov biodegradation sai ntawm cov organic cov khoom siv rau cov khoom zoo, tshuaj lom-dawb.
Ntawm no yog cov txiaj ntsig ntawm kev sim sib piv nrog kev siv cov nplooj lwg nrog tsev nplooj lwg
| Muaj Composting | Tsev Nplooj lwg | |
| Sij hawm | 3-4months (Ntev: 180days) | 3-13months (ntev tshaj plaws: 12months) |
| Lub hom phiaj | ISO 14855 | |
| Qho so | 58 ± 2 ℃ | 25 ± 5 ℃ |
| Tus txheej txheem | Qhov tsis haum degradation> 90%;Qhov txheeb ze cuam tshuam> 90% | |
Txawm li cas los xij, kev sib tw hauv tsev yog txoj kev zoo heev kom txo cov pov tseg thiab xa cov roj carbon rau hauv av. Txawm li cas los xij, tsev composting tsis muaj kev sib xws thiab kev tswj hwm ntawm kev muaj cov chaw muaj kev sib sau ua ke. Ntim hnab ntim khoom (txawm tias thaum ua ke nrog cov zaub mov pov tseg) yuav tsum muaj qhov kub tshaj tuaj yeem ua tiav lossis txhawb nqa hauv lub tsev nplooj lwg. Rau cov nplai loj cov khoom seem kos duab, Bioplastics loj, thiab cov orgetics ,, composting yog qhov kawg ntawm kev ua neej nyob.
