Ua kom cov neeg siv khoom xav txog kev rov ua dua ntawm cov ntaub ntawv pov tseg tsis zoo

1.Nyob tob txog kev coj ua ntsuab

Ib tonne ntawm cov ntawv pov tseg, nyob rau hauv kev rov ua dua tshiab, muaj peev xwm ua tau daim ntawv cog lus tshiab ntawm lub neej, hloov mus rau 850 kg ntawm daim ntawv rov ua dua. Qhov kev hloov pauv no tsis tsuas yog qhia txog kev siv cov peev txheej zoo xwb, tab sis kuj tseem tiv thaiv 3 cubic meters ntawm cov khoom siv ntoo muaj txiaj ntsig, kom lawv tuaj yeem ua kom muaj kev vam meej hauv hav zoov thiab tswj kev sib npaug ntawm ecological. Nyob rau tib lub sijhawm, cov txheej txheem no txuag tau 100 cubic meters ntawm dej, uas yog qhov zoo rau kev daws qhov teeb meem ntawm dej tsis txaus.

Nyob rau hauv cov nqe lus ntawm kev txo cov pa phem ib puag ncig, txhua tonne ntawm cov ntawv siv pov tseg txo kev siv 300kg ntawm cov khoom siv tshuaj, yog li txo cov emissions ntawm cov khoom tsis zoo uas yuav raug tsim thaum lub sij hawm tsim khoom. Tsis tas li ntawd, 1.2 tonnes ntawm thee thiab 600 kWh ntawm hluav taws xob tuaj yeem txuag tau, uas yog qhov tseem ceeb ntawm kev txuag hluav taws xob thiab txo qis emissions, thiab txhawb kev txhim kho lub zog ruaj khov.

Siv 1 tonne ntawm cov khoom tsim los ntawm 100% cov ntawv siv rov ua dua tshiab yuav txo cov pa roj carbon dioxide emissions los ntawm 11.37 tonnes. Qhov no tsis yog tsuas yog kev xav txog tus kheej ib puag ncig kev paub, tab sis kuj yog ib qho lus teb zoo rau kev hloov pauv huab cua thoob ntiaj teb. Kev siv cov ntawv siv rov ua dua yog maj mam dhau los ua lub zog tseem ceeb hauv kev txhawb nqa kev nyob ntsuab thiab tsim kom muaj lub neej muaj roj carbon tsawg.

2.Residue nyob rau hauv cov ntawv pov tseg, cov khoom siv raw rau cov ntawv siv dua, thiab lawv cov kev cuam tshuam
Cov ntaub ntawv pov tseg hauv cov txheej txheem rov ua dua tshiab, feem ntau nqa ntau yam khoom seem, cov khoom seem no tsis tsuas yog ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv, tab sis kuj yuav muaj kev cuam tshuam tsis zoo rau ib puag ncig ntuj.

Cov hlau hnyav yog ib qho ntawm cov khoom seem hauv cov ntawv pov tseg. Cov txheej txheem tsim cov ntawv rov ua dua tuaj yeem muaj cov hlau hnyav xws li txhuas, mercury thiab cadmium. Cov hlau hnyav no muaj tshuaj lom rau tib neeg lub cev, thiab kev raug mob ntev los yog kev noj cov tshuaj uas muaj cov hlau hnyav yuav ua rau muaj teeb meem ntau yam kev noj qab haus huv. Qhov hnyav dua, cov hlau hnyav tsis yooj yim degraded nyob rau hauv ib puag ncig ntuj, thiab thaum lawv nkag mus rau hauv ecosystem, lawv tuaj yeem sib sau ua ib kauj ruam los ntawm cov khoom noj khoom haus, thaum kawg ua rau kev puas tsuaj rau ecological tshuav nyiaj li cas.
Organic teeb meem kuj yog ib qho tseem ceeb ntawm cov khoom seem hauv cov ntawv pov tseg. Thaum cov ntawv rov ua dua tuaj rau hauv kev sib cuag nrog cov tshuaj thiab cov kab mob hauv lub sijhawm siv, cov ntaub so ntswg hauv nws yuav raug decomposed rau hauv cov organic teeb meem, xws li benzene thiab phenol. Cov organic tshuaj no muaj feem cuam tshuam rau tib neeg lub cev thiab ib puag ncig, thiab tuaj yeem ua rau muaj teeb meem kev noj qab haus huv xws li khaus tawv nqaij thiab teeb meem ua pa. Lawv kuj tseem tuaj yeem paug cov dej thiab av, cuam tshuam rau kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag thiab tsiaj txhu.

Cov kab mob thiab cov cab kuj tseem yog cov seem hauv cov ntawv siv dua tshiab uas yuav tsum tsis txhob raug ignored. Cov ntaub ntawv pov tseg tuaj yeem muaj ntau yam kab mob thiab cov kab mob cab, xws li Escherichia coli, pneumococcus thiab cab, yog tias nws tsis raug kho thaum lub sijhawm rov ua dua tshiab. Cov kab mob no ua rau muaj kev hem thawj loj rau tib neeg kev noj qab haus huv thiab kev huv ntawm ib puag ncig, thiab tuaj yeem ua rau kis kab mob thiab kev ua qias tuaj ib puag ncig.

Nyob rau hauv cov txheej txheem ntawm cov ntaub ntawv pov tseg rov qab thiab rov siv dua, yuav tsum tau ua kom muaj kev ntsuas zoo, xws li txhim kho kev sib cais ntawm cov ntawv pov tseg, txhim kho cov txheej txheem tsim cov ntawv pov tseg thiab ntxiv dag zog rau cov tshuaj tua kab mob ntawm cov ntawv siv dua tshiab, txhawm rau txo cov kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig los ntawm cov khoom seem hauv cov ntawv pov tseg. Nyob rau tib lub sijhawm, cov pej xeem yuav tsum txhim kho kev paub txog ib puag ncig, kev siv tsim nyog thiab pov tseg cov ntawv pov tseg, thiab sib koom ua ke tiv thaiv peb ib puag ncig ecological.

3.Kev pheej hmoo ntawm residue nyob rau hauv cov ntawv siv dua
Cov txheej txheem tsim cov ntawv siv dua tshiab yog cov txheej txheem nyuaj thiab muag heev, uas suav nrog kev ua kom cov nqaij mos ntawm qhov kub thiab txias, ntxiv cov calcium hypochlorite, thiab cov tshuaj tua kab mob siab thib ob thaum lub tog raj kheej molding. Cov txheej txheem ntawm kev ua cov txheej txheem no tua tau cov kab mob thiab cov kab mob loj, yog li ua kom cov qauv kev tu cev ntawm cov ntawv siv dua tshiab. Txawm li cas los xij, txawm tias nrog cov txheej txheem tsim khoom nruj no, tseem muaj qee qhov pwm spores uas yuav nyuaj rau tshem tawm, suav nrog cov tsiaj xws li Penicillium, Aspergillus erythropolis thiab Aspergillus flavus.
Feem ntau tshwm sim los ntawm cov ntawv pov tseg, cov pwm spores no tau yoog rau lawv ib puag ncig thiab tuaj yeem muaj sia nyob hauv ntau yam mob hnyav. Txawm tias nyob rau hauv qhov kub siab txog li ob peb puas degrees, cov spores tseem muaj peev xwm ciaj sia. Nyob rau tib lub sijhawm, vim lawv cov tshuaj lom neeg ruaj khov, muaj zog acids thiab alkalis thiab oxidising tshuaj tua kab mob thiab lwm yam kev siv tshuaj tua kab mob feem ntau tsis muaj txiaj ntsig tiv thaiv lawv.
Ntawm cov kab mob pwm no, Aspergillus flavus yog tshuaj lom tshwj xeeb. Nws yog dav suav hais tias yog ib qho ntawm cov tshuaj lom neeg tshaj plaws nyob hauv lub ntiaj teb, nrog rau cov tshuaj toxicity ntau tshaj ntawm cov tshuaj phem xws li nicotine thiab formaldehyde. Nws tsuas yog siv 0.1 gram ntawm aflatoxin ua rau tuag taus nyob rau lub sijhawm luv luv. Qhov hnyav dua, txawm tias nws tsuas yog noj lossis nqus tau hauv cov feeb ntau dhau lub sijhawm ntev, aflatoxin yuav ua rau muaj kev puas tsuaj loj rau tib neeg ua pa thiab plab zom mov, thiab tseem tuaj yeem ua rau cov qog nqaij hlav xws li mob qog noj ntshav, mob ntsws cancer thiab mob plab. Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb tau muab cais tawm tias nws yog cov kab mob carcinogen, thiab nws cov qib ntawm kev puas tsuaj tsis tuaj yeem tsis quav ntsej.

Ua tsaug, Aspergillus flavus spores yuav mus dormant nyob rau hauv qhov kub thiab txias ib puag ncig, yog li txwv tsis pub lawv txoj kev loj hlob thiab kev loj hlob ib ntus.
