Ntawm qhov dej phwj mus ntawm cov chaw ua si hauv Jiangsu, cov kws tsim txuj ci pom tias yog cov qauv kev coj txawv txawv: Cov qauv dej khib nyiab tseem ua rau ntses poj niam txiv neej pw hauv tus dej.
Qhov kev tshawb pom no Tore qhib lub qhov txhab tuag ntawm kev ua haujlwm lim dej niaj hnub - cov moj khaum "theoretical moj khaum uas tau siv xyoo tshiab tau dhau los ua lub ntsej muag tshiab.
Qhov tshwm sim ntawm ntau tshaj 3, {1}}} Cov pa paug tshiab, thiab microoplastics yog yuam kom tag nrho cov khoom siv dej phwj tuaj yeem ua kom rov tsim dua.
Kev Txiaj Ntsig Ua Rau Cov Khoom Siv Ntawm Cov Khoom Siv Tshuaj Lom Zem: Thaum lub sijhawm ua haujlwm sib ntsib kev sib tw ntawm lub sijhawm
Cov dej phwj dej tam sim no yog ua raws li txoj kev xav ntawm cov organic teeb meem nyob rau hauv lub xyoo pua puv 19. Nws cov tub ntxhais tseem ceeb yog kom decompose macromolecular teeb meem rau cov molecules me me los ntawm kev siv roj hydrolysis thiab acidification, thiab tom qab ntawd ua tiav kev tsis zoo los ntawm kev kho mob aerobic.
Cov txheej txheem no tau ua tau zoo rau cov cim uas suav tias yog tus lej thiab lub cev, tab sis nws yog tsis muaj kuab lom tshiab nrog cov qauv molecular hnyav thiab hnyav.
Cov ntaub ntawv xeem los ntawm Petrochemical lub tuam txhab pom tias tom qab kho cov txheej txheem tsoos, uas yog qhov tseem ceeb li 12.6ug \/ l, uas yog 25 zaug ntawm kev nyab xeeb kev nyab xeeb.
Cov txheej txheem kev kho mob uas twb muaj lawm yuav dhau los ua "kev ua yeeb yam tshiab" ntawm cov pa phem tshiab.
Kev tshawb fawb los ntawm Zhejiang University pom tias cov txheej txheem kho tshuab hluav taws xob hloov pauv tau nyiaj ntau ntxiv rau kev nce qib 30% ntawm cov nanoeplastics los ntawm {}} kev txiav txim ntawm qhov ntau.
Cov kev tswj hwm no tau nthuav tawm cov kev pheej hmoo loj ntawm tsuas yog hloov cov cuab yeej ua ib txwm muaj thev naus laus zis.
Cov yam ntxwv subversive ntawm cov kuab paug tshiab: los ntawm kev ua rog molecular rau kev ua si system
Cov kuab paug tshiab yog sau dua cov kev cai yooj yim ntawm kev tswj kev qias neeg. Piv nrog tso kua kuab kuab paug, lawv muaj peb yam ntxwv cuam tshuam:
Nyob rau hauv cov molecular degition, cf kev sib khi zog ntawm perfluorinated tebchaw yog siab li 485Kj \/ Mol, deb tshaj qhov muaj peev xwm tawg ntawm cov txheej txheem oxidation;
Nyob rau hauv cov nqe lus ntawm Kab Mob Kab Mob, endocrine disnupted tuaj yeem tsim cov txiaj ntsig econological los tsim cov txiaj ntsig ec \/ l
Hais txog ntawm cov txheej txheem ntawm kev nqis tes ua, microplastics tuaj yeem siv los ua cov pob volutant los tsim cov pa phem sib xyaw ua ke network.
Qhov kev hloov pauv no yuav tsum muaj kev tswj hwm thev naus laus zis kom tau kev tswj hwm ntawm tag nrho cov kev tswj hwm kom khiav tawm ntawm kev tswj hwm kev tswj hwm kev tswj hwm.
Tom qab npaj txhij spme-gc \/ ms ua ke thev naus laus zis, lub tuam txhab hluav taws xob ntse tau kuaj 12}}}. 01\/2ug \/ l.
Txoj kev npaj "kev txiav txim rau kev tswj hwm cov pa paug tshiab" tshaj tawm los ntawm Ministry of ecology thiab ib puag ncig hauv 2021 systemtically txhais cov penutants tshiab rau thawj zaug:
Zais Toxicity: Cov ntshav lom
Kev tsiv teb tsaws thiab kev hloov pauv: Pub dawb tsiv teb nruab nrab ntawm dej-av-huab cua xov xwm, kev cuam tshuam nrog kev cuam tshuam nrog kev sib cuam tshuam
Cov nyhuv synergistic: kev sib xyaw ua ke ntawm ntau cov pa paug tsim tawm "cocktail nyhuv"
Kev lom neeg roj ntsha: cov khoom siv nthuav dav ua ke raws cov khoom noj khoom haus
Nqa cov khoom siv hluav taws xob ua piv txwv. Cov khoom lag luam ntawm trichlorethylene nyob rau hauv ntau lawm quav tshuaj ntau dua li niam txiv, thiab photocatalytic kev kho mob hloov chaw ua chlorinated los-cov khoom siv nrog cov carcinogenicity. Qhov "kho mob" muaj ntau yam nyob rau hauv kev lag luam xws li tshuaj thiab luam ntawv thiab dylying.
Kev tsim kho ntawm kev tswj hwm cov txheej txheem: los ntawm cov txheej txheem kev txhim kho kom ua rau kev ntseeg
Txhawm rau kom tau raws li cov kev sib tw ntawm cov pa phem tshiab, nws yog qhov tsim nyog los tsim cov txuj ci ua ke ntawm "kev tiv thaiv kev tiv thaiv-system tiv thaiv-system thiab tswj".
Hauv chaw ua si hauv kev ua si hauv Zhejiang, engineers tsim cov duab sib nqus molecular imprinting nrog kev tshem tawm kev ua haujlwm ntawm 99.8% rau tetraccline tshuaj tua kab mob;
Lub tuam txhab tshuaj lom neeg hauv Shanghai siv AV \/ Persulfate Advanced Oxidation oxidation ntawm Perfluorinated tebchaw rau ntau dua 85%. Qhov tseem ceeb ua txhaum ntawm cov thev naus laus zis nyob rau qhov tseeb ntawm kev txheeb xyuas thiab tsom cov qauv ntawm cov qauv molecular ntawm cov pa phem.
Kev tsim kho dua ntawm kev tswj hwm cov kev tswjfwm ntawm kev ua siab tawv
Hauv qhov kev ua tsov ua rog molecular, kev kho kev lag luam pov tseg tau raug ua tiav ib qho kev hloov pauv paradigm uas tsis tau pom nyob hauv ib lub xyoo pua.
Thaum cov qauv molecular ntawm cov pa dawb huv tshiab twv cov kev txwv ntawm cov kev tswj hwm kev ruaj ntseg thiab kev txhim kho cov kev ruaj ntseg ntawm txoj kev nyab xeeb ntawm txoj kab kev nyab xeeb hauv lub sijhawm tshiab.
Qhov no tsis yog tsuas yog kev sib tw ua haujlwm, tab sis kuj tseem yog qhov kawg ntawm tib neeg thiab cov neeg muaj kuab lom hais txog kev muaj sia nyob muaj tswv yim.
Kev tsim kho sib sib sib nqus ntawm kev tswj hwm kev tswj hwm
1. Cov ntaub ntawv txhawb nqa
Tshawb nrhiav los ntawm Tsev Kawm Ntawv ntawm Ib puag ncig ntawm Tsinghua University qhia tau tias 70% ntawm kuv lub teb chaws muaj cov khoom siv khib nyiab hauv kev kho mob ntawm cov pa phem tshiab
EU qab ntug 2020 kev pab cuam tau nqis peev tau 1630 lab nyiaj ntev hauv kev txhim kho cov cuab yeej tshem tawm cov tshuaj muaj kuab paug tshiab
Tom qab Nyij Pooj tau siv txoj cai tshuaj tshuaj lom neeg, lub puab tsaig ntawm cov organic teeb meem hauv ib puag ncig xov xwm poob los ntawm 80% hauv kaum xyoo
2. Lub tswv yim ntawm cov kuab paug tshiab hauv kev txhim kho cov txheej txheem kev tswj hwm
Tsim cov txheej txheem emission system raws li kev lom zem
Tsim kho cov thev naus laus zis kev soj ntsuam thaum ntxov
Tsim kom muaj "lub neej taug kev ntawm emitters" lub luag haujlwm mechanism
Txhawb nqa kev hloov pauv ntawm cov dej phwj tuaj ua rau "ib puag ncig cov chaw ua si taug ib puag ncig"
3. Saib xyuas
Thaum 4, {{000 Microplastician cov lus \/ ㎡ pom tau tias kev lag luam MBR Qhov kev sib ntaus sib tua no yuav tsum tsis tsuas yog siv thev naus laus zis, tab sis kuj tseem muaj kev hloov pauv ntawm kev txo qis "ntau dua" ntawm cov kuab paug rau kev pheej hmoo tswj ntawm "Zoo". Tsuas yog los ntawm kev tsim kom muaj kev tiv thaiv ib cheeb tsam thiab tswj hwm "los ntawm cov molecules rau cov kab ke ecosystems" Peb tuaj yeem tsim kab mob ntawm kev tswj hwm ntawm cov pa phem tshiab.
4. Hu rau kev nqis tes ua
Kev lag luam yuav tsum ua cov khoom lag luam ntawm cov txheej txheem ntau lawm, kev tswj hwm cov tsev kawm ntawv tshiab yuav tsum tawg ntawm cov tshuab xaiv ntawm kev xaiv tshuab. Qhov kev sib ntaus sib tua no ntsig txog ecological kev nyab xeeb thiab kev noj qab haus huv yuav tsum muaj kev txawj ntse thiab lub luag haujlwm ntawm txhua tus neeg tuaj koom.
