Indlela yokuphucula umgangatho womoya weklasi?

Igumbi lokufundela yeyona ndawo iphambili abafundi yokufunda yonke imihla.Umgangatho womoya eklasini unxulumene ngokuthe ngqo nempilo yabafundi yomzimba nengqondo kunye nempumelelo yokufunda.Imizimba yabo ikwinqanaba lokukhula kunye nokukhula, kwaye ukukhuseleka kwabo kwizinto ezingcolisayo kubuthathaka kakhulu kunokwabantu abadala.Indawo abafunda kuyo ibhetele nangakumbi.Ifuna ingqalelo ekhethekileyo.Ekuqaleni kwezikolo eziziiprayimari nezasesekondari, i-“Haze Prevention Strategy” yashwankathela iingxaki zomoya eklasini yaza yabonelela ngeemeko ezithile zezikolo zaseJamani ukuze kusetyenziswe amasebe emfundo nabazali.

1. Umoya wegumbi leKlasi elineengozi ezine

• Ukungena kwe-PM2.5 yangaphandle kuyingozi☆☆☆☆
• Uxinzelelo lwe-CO2 oluphezulu luyingozi☆☆
• Ukusasazeka kweebhaktheriya ezosulelayo kuyingozi☆☆☆
• Iingozi zongcoliseko lwe-formaldehyde☆☆☆☆

Iingozi zokungena ngaphandle PM2.5 Ukalo lweenkwenkwezi: ☆☆☆☆

Ngemini enenkungu, nokuba iingcango kunye neefestile zivalwe ngokuqinileyo, amasuntswana othuli e-PM2.5 asenokungena kumagumbi okufundela ngeengcango neefestile kunye nezikhewu kwisakhiwo.Iimvavanyo ezingagqitywanga zibonise ukuba ugxininiso lwe-PM2.5 eklasini lungaphantsi kancinane kunolwangaphandle malunga ne-10% ukuya kwi-20%.Oku kungenxa yokuba bonke abafundi basebenza “njengabasulungekisi benyama yabantu.”Amanyathelo othintelo lwabafundi ngokuchasene ne-PM2.5 aphantse alingane no-zero.Ngenxa yokuba amasuntswana e-PM2.5 mancinci kakhulu, umzimba womntu awukwazi ukuwahluza nokuwavimba.Amasuntswana aginywa ngokulula ngamaseli e-alveolar phagocytic kwaye angena kwi-bronchus.Ngoko ke, i-PM2.5 inokubangela umonakalo omkhulu kwindlela yokuphefumula komntu kwaye ibangele lula i-asthma, i-bronchitis, njl.

Uxinzelelo lwe-CO2 ephezulu yonakalisa ukalisho lwenkwenkwezi: ☆☆

Iingcebiso ezidumileyo zesayensi: Uxinaniso lwe-CO2 lwangaphandle lumalunga ne-400ppm, kwaye umntu ukhupha malunga ne-15 ilitha ye-CO2 ngeyure xa ehleli.Kwiintsuku zenkungu, ebusika nasehlotyeni, iingcango zeklasi kunye neefestile zihlala zivaliwe, kwaye ukugxininiswa kwe-CO2 yangaphakathi kuyanda.Ugxininiso lweCO2 kumagumbi okufundela abafundi abangama-35 lufikelela ku-2000 ~ 3000ppm.Uxinzelelo oluphezulu lwe-CO2 lubangela ukuba abafundi bavelise iimpawu ezinjengokuqina kwesifuba, isiyezi, ukuphazamiseka, ukozela, kunye nokulahleka kwenkumbulo.Ke ngoko, xa utitshala exela ukuba abantwana bakho bahlala besiya esikolweni, kusenokwenzeka ukuba bachatshazelwe yi-CO2 embi.

Ngokweziphumo zovavanyo lwengqwalasela yomfundi e-Austria, xa ugxininiso lwe-CO2 lunyuka ukusuka kwi-600-800ppm ukuya kwi-3000ppm, ukusebenza kakuhle komfundi kwehla ukusuka kwi-100 ukuya kwi-90%.I-Arhente yoKhuseleko lweNdalo yaseJamani incoma ukuba xa ugxininiso lungaphantsi kwe-1000ppm, imeko yokucoceka ifanelekile, xa i-concentration i-1000-2000ppm, ingqalelo kufuneka ihlawulwe kwaye kufuneka kuthathwe amanyathelo okungenisa umoya.Xa i-CO2 inkulu kune-2000ppm, imeko yococeko lomoya ayamkelekanga.

Iintsholongwane ezosulelayo zisasaza ingozi yokulinganisa inkwenkwezi: ☆☆☆

Amagumbi okufundela axinene kwaye nokufuma kuphezulu, kwaye iibhaktheriya zinokuzala kwaye zisasazeke ngokulula, ezinjengoqwilikana, irhashalala, umkhuhlane, i-bacillary dysentery, njl.;Iikhampasi zisesichengeni sokuqhambuka kwezifo ezosulelayo ukusuka kuMatshi ukuya kuAprili nango-Oktobha ukuya kuDisemba minyaka le.Kwi-2007, i-Shanghai yenze uhlolo lomoya kwi-8 yesikolo samabanga aphantsi kunye nephakathi kwiSithili saseFengxian, kwaye yafumanisa ukuba inani elipheleleyo leebhaktheriya zomoya kwigumbi lokufundela laliyi-0.2 / cm2 ngaphambi kweklasi, kodwa lenyuka laya kwi-1.8 / cm2 emva kweklasi yesi-4.Ukuba igumbi lokufundela aliphefumlelwanga kakuhle, kwaye inani elikhulu leentsholongwane eziveliswa ngabafundi abakhohlelayo kwaye bathimla ziya kuqokelelana kwaye zisasazeke, umntu omnye uya kugula kwaye abantu abaninzi baya kosulelwa.

Ukalo lwenkwenkwezi yengozi yongcoliseko lweFormaldehyde: ☆☆☆☆

Ukuba ligumbi lokufundela elisandula ukwakhiwa okanye elihlaziyiweyo, izinto zokuhombisa zokwakha kunye needesika ezintsha nezitulo ziya kutshintsha iigesi eziyingozi, kubandakanya i-formaldehyde kunye ne-benzene.Ungcoliseko lokuhombisa luyingozi kakhulu kwimpilo yabafundi, kwaye kulula ukubangela izifo zegazi kubantwana, njenge-leukemia;ngelo xesha, kwandisa iziganeko ze-asthma;kwaye ichaphazela ukukhula kwengqondo kwabafundi.NgoSeptemba ka-2013, iSebe le-Wenzhou Environmental Supervision Supervision Detachment lihlole ngokungenamkhethe amagumbi okufundela angama-88 kumaziko emfundo yabantwana abasaqalayo ali-17 e-Wenzhou, angama-43 kuwo abe ngaphaya kwemigangatho ye-formaldehyde kunye ne-organic volatiles epheleleyo, oko kukuthi, i-51% yamagumbi okufundela anomgangatho womoya ongafanelekanga.

2. Amava aseJamani kwi-classroom air hygiene

Kwixesha elidlulileyo, kwakukho iindaba zokuba abazali bathumela izixhobo zomoya kumagumbi okufundela esikolweni.Intshukumo enjalo inokunciphisa kancinci umonakalo womoya omdaka kubafundi;nangona kunjalo, ukusombulula iingozi ezine ezinkulu ezikhankanywe ngasentla, oku kukuhla nje kwibhakethi, kwaye kukude ngokwaneleyo.Ukusombulula iingozi ezine zomoya weklasi, kwi-PM2.5, kubonakala ngathi iingcango kunye neefestile kufuneka zivaliwe. ngokuqinileyo, kunye nezinye iingozi ezintathu, iingcango kunye neefestile kufuneka zivulwe ukunyusa umoya.Indlela yokusombulula oku kuphikisana?Amava ezikolo zaseJamani kukuba umphumo wokungena komoya wefestile uchaphazeleka kwicala lomoya kunye nesantya, kwaye umphumo awunakuqinisekiswa, kwaye umoya wefestile ebusika nasehlotyeni nawo unqatshelwe;Ngoko ke, ukuphucula umgangatho womoya weklasi, kuyimfuneko ukulawula ngokusebenzayo nangokufanelekileyo ukubonelela kunye nokukhupha umoya, ukuze kubonelelwe umoya owaneleyo.Isixa somoya omtsha, khupha umoya ovuthuzayo wangaphakathi.Kukho ubukhulu becala iindidi ezimbini zezixhobo zomatshini zokungenisa umoya ezifakwe kwigumbi lokufundela:

Izixhobo zokungenisa umoya ezisembindini.

Ilungele izikolo ezisanda kwakhiwa, kwaye umthamo wokungenisa umoya ungadibana nomoya ococekileyo oyi-17 ~ 20 m 3;/h kumfundi ngamnye.Umfo omkhulu ophezu kophahla lomfanekiso wekhava sisixhobo sokungenisa umoya esiphakathi.Imibhobho engqukuva emhlophe phezulu kwifoto engezantsi ziindlela zokuhambisa umoya omtsha kunye neendawo ezivulekileyo zokuhambisa umoya kwiipaseji zokufundela.

Izixhobo zokungenisa umoya ezinatyisiweyo

Ukusetyenziswa kwezixhobo zokungenisa umoya ezinatyisiweyo kulungele ukuhlaziywa kwezikolo, kwaye igumbi lokufundela ngalinye lingena umoya ngokuzimeleyo.Izikwere ezinemibala ekhanyayo eludongeni olungaphandle kumfanekiso ongezantsi zizixhobo zokungenisa umoya.

Ezinye izikolo zaseJamani nazo zinokubonwa komgangatho womoya kunye nezixhobo ze-alamu, kwaye umthamo womoya ungalungiswa ngokuhambelana ne-CO2 yoxinaniso.Ukongeza, uninzi lofakelo lokungenisa umoya eJamani lukwanazo nezixhobo zokubuyisa ubushushu, kunye nokusebenza kakuhle kokubuyisela ubushushu ngaphezu kwe-70%, kunye nogxininiso olukhulu kugcino lwamandla kunye nokunciphisa ukukhutshwa.
