Cov pa roj carbon emissions los ntawm aquaculture feem ntau yog los ntawm kev siv hluav taws xob hauv kev tsim khoom noj, ua cov khoom siv raw, thiab pov tseg pov tseg. Tsawg-carbonization yog ib lub sijhawm ntev - yuav tsum tau ua kom muaj kev sib npaug ntawm ecological. Niaj hnub no cov khoom noj khoom haus aquaculture, los ntawm lub zog- txuag thev naus laus zis, cov txheej txheem ib puag ncig tus phooj ywg, thiab cov khoom siv rov ua dua tshiab, txo cov pa roj carbon emissions los ntawm aquaculture, dhau los ua ib qho kev txhawb nqa rau qis -carbon aquaculture thiab ua kom pom qhov zoo ntawm ecological zoo.

Lub zog-cov khoom siv khoom noj khoom noj muaj txiaj ntsig txo qis kev siv hluav taws xob thiab cov pa roj carbon emissions thaum lub sijhawm tsim khoom los ntawm kev tsim kho thev naus laus zis. Cov khoom siv ua khoom noj niaj hnub muaj lub zog siv lub zog siab, nrog rau kev siv lub zog hauv cov txheej txheem crushing thiab pelleting accounting rau ntau tshaj 30% ntawm tag nrho cov zog siv hauv aquaculture. Lub zog tshiab- cov cuab yeej siv tau zoo siv lub tshuab hluav taws xob sib txawv thiab cov cuab yeej siv hluav taws xob pov tseg. Ntau zaus lub cev muaj zog tuaj yeem hloov kho lawv qhov ceev raws li cov khoom ntim, txuag 20%-30% ntau zog dua li cov motors ib txwm muaj; khib nyiab hluav taws xob tsim nyob rau hauv lub pelleting theem yog zoo tu qab tso los ntawm lub tshav kub exchanger thiab siv rau preheat raw cov ntaub ntawv, ntxiv txo zog noj. Tom qab lub tshuab pub khoom noj hauv Jiangsu Xeev tau qhia txog cov cuab yeej no, kev siv hluav taws xob ib tuj ntawm cov khoom noj tau txo qis los ntawm 80 kWh mus rau 50 kWh. Raws li kev tsim khoom noj txhua xyoo ntawm 10,000 tons, qhov no txhais tau tias yuav txo tau kwv yees li 30 tons ntawm carbon emissions hauv ib xyoos. Lub caij no, kev ua haujlwm siab ntawm cov khoom siv txo cov khoom siv lub sijhawm ua haujlwm, txo qis carbon emissions thiab tsim lub voj voog tsim txiaj ntawm "kev txuag hluav taws xob-tsawg carbon-ecology".

Environmentally friendly feed processing equipment txo qis carbon emissions indirect thaum lub sij hawm aquaculture los ntawm kev txo cov kev siv tshuaj additives. Kev noj zaub mov yuav tsum muaj ntau cov tshuaj ntxiv los txhim kho palatability thiab khaws cia. Cov additives no tsim cov pa roj carbon emissions ntxiv thaum lub sij hawm metabolism thiab decomposition nyob rau hauv cov tsiaj dej. Cov cuab yeej siv tshuaj lom neeg tshiab siv cov cuab yeej microbial fermentation los ferment cov ntaub ntawv cog rau hauv cov khoom noj lom. Los ntawm kev ua haujlwm metabolic ntawm cov kab mob, lub palatability thiab txee lub neej ntawm cov khoom noj yog txhim kho, txo kev siv tshuaj ntxiv los ntawm ntau tshaj 60%. Piv txwv li, hauv kev tsim khoom noj tilapia, cov khoom siv no siv cov kab mob lactic acid los ferment soybean noj.

Cov txiaj ntsig pub tuaj yeem khaws cia rau ntau tshaj 30 hnub yam tsis muaj kev ntxiv cov tshuaj tua kab mob, thiab kev zom zaub mov thiab kev nqus ntawm tilapia tau txhim kho zoo, txo cov pa roj carbon emissions los ntawm fecal paug. Tsis tas li ntawd, cov probiotics uas tsim thaum lub sij hawm fermentation tuaj yeem txhim kho cov dej hauv microecological ib puag ncig, txhawb kev loj hlob ntawm cov txiaj ntsig algae, txhim kho cov pa roj carbon sequestration peev ntawm lub cev dej, thiab ntxiv txo cov pa roj carbon hneev taw ntawm aquaculture ecosystem.

Cov peev txheej- cov khoom siv rov ua dua tshiab tau ua tiav cov pa roj carbon rov ua dua tshiab thiab txo qis emission los ntawm kev siv cov khoom pov tseg. Uneaten pub, excrement, thiab ua byproducts los ntawm aquaculture, yog hais tias ncaj qha emission, yuav tsim ib tug loj npaum li cas ntawm methane (ib tug muaj zog tsev cog khoom gas). Cov khoom siv rov ua dua tshiab, txawm li cas los xij, tuaj yeem hloov cov khoom pov tseg rau hauv biogas lossis organic chiv, ua tiav cov peev txheej rov qab los thiab siv. Ib tug loj - ua liaj ua teb aquaculture nyob rau hauv Guangdong yog nruab nrog cov khoom siv pov tseg uas muaj peev xwm ua tau 10 tons ntawm uneaten pub thiab excrement txhua hnub, ua 500 cubic meters ntawm biogas rau cua sov pub ntau lawm.

Qhov no txo qis kev siv roj av los ntawm kwv yees li 18,000 cubic meters ib xyoos ib zaug, coj mus rau qhov txo qis ntawm 40 tons ntawm carbon emissions. Tib lub sijhawm, cov txiaj ntsig biogas residue tuaj yeem ua rau cov organic chiv rau cov qoob loo ib puag ncig, tsim cov qauv kev ua liaj ua teb ncig ntawm "kev ua liaj ua teb- khib nyiab- cog," ua tiav kaw - siv cov pa roj carbon monoxide. Daim ntawv thov ntawm cov cuab yeej no tsis tsuas yog txo cov pa roj carbon emissions los ntawm aquaculture tab sis kuj txhim kho ob qho tib si ecological thiab kev lag luam cov txiaj ntsig ntawm aquaculture, muab txoj hauv kev ua tau rau qhov qis -carbon kev loj hlob ntawm aquaculture.
