Kev tiv thaiv kev ua qias tuaj thiab kev tswj hwm hauv cov txheej txheem ua cov ntawv tso quav tso zis tuaj yeem muab faib ua ob pawg: hauv-cog rau ntawm qhov chaw ib puag ncig zoo nkauj thiab kev kho dej khib nyiab tawm ntawm qhov chaw.
Kev kho mob hauv cov nroj tsuag
Xws li: ① ntxiv dag zog rau kev npaj (plua plav, sediment, tev, pith, thiab lwm yam), kev siv cov dej zaj duab xis plua plav collector, txo cov plua plav paug hauv kev npaj rhiav, sau cov khib nyiab, combustion rov qab thermal zog, xws li kev siv cov bark, ntoo chips, nyom burner boiler; ② kev txuag dej, dej dawb rov siv dua, ntau zaus cov dej rov siv dua; ③ txhawm rau txhim kho kev tshem tawm cov dej cawv dub, ntxiv dag zog rau kev tswj hwm ntawm lub txee tam sim no ntxuav kom ntau ntxiv, txo cov dej cawv dub nrog cov kua txiv hmab txiv ntoo tshem tawm ntawm kev ntxuav, thiab siv cov khoom noj khoom haus zoo tshaj plaws rov qab los. ntawm cov tshuaj thiab cov thev naus laus zis thev naus laus zis, xws li alkali rov qab, thiab lwm yam kev siv dej pov tseg. Thiab siv qhov zoo tshaj plaws ua noj ua kua dej rov qab ntawm cov tshuaj thiab thermal zog technology, xws li alkali rov qab, nrog rau lwm yam kev siv cov khoom siv kua khib nyiab; ④ chlorine dioxide los yog oxy-alkali bleaching, los yog hydrogen peroxide bleaching, thiaj li yuav txo tau cov dej khib nyiab lignin chloride, chlorophenol thiab lwm yam tshuaj lom emissions; ⑤ qias neeg condensate purified los ntawm chav extraction txoj kev rau reused kom txo tau cov dej khib nyiab emissions ntawm txo sulfur thiab soluble organics; ⑥ sau los ntawm kev khiav tawm thiab tso dej cawv dub, kua ntsuab, kua dawb, nrog lub computer tswj hluav taws xob los ntsuas nws cov concentration, txiav xa rov qab mus rau lub tank sib txuas, kom txo qis emissions; ⑦ rov qab ntawm cov fibers uas ploj lawm, txo cov ntsiab lus ntawm cov khoom raug tshem tawm hauv cov dej khib nyiab; ⑧ txhawm rau txhim kho kev rov zoo ntawm turpentine sulphate xab npum, txo cov pa tawm ntawm cov tshuaj lom; ⑨ kev kho cov khoom pov tseg, kev siv cov combustion kom rov qab tau cov cua sov, kev siv dav thiab sau cov qhov dej ntawm peb hom kev kho mob; ⑩ kev kho cov plua plav, tuaj yeem siv hluav taws xob tshem tawm plua plav, dej zaj duab xis tshem tawm plua plav thiab cua daj cua dub cais thiab lwm yam khoom siv; huab cua ua paug Separator thiab lwm yam khoom siv; Kev kho cov pa phem, sau cov pa roj tsw qab hauv txhua qhov kev cob qhia, suav nrog cov pa roj tsw qab uas tau tsa los ntawm cov dej qias neeg qias neeg, tom qab txias, lub cev qhuav dej, tawg-pov thawj thiab lwm yam kev ntsuas, xa mus rau lub boiler, alkali rov qab rauv los yog txiv qaub kiln combustion kho;? Kev kho suab nrov, siv cov kev ntsuas kom tshem tawm kev vibration, suab rwb thaiv tsev thiab hloov mus rau cov khoom siv suab nrov.
Kev kho dej khib nyiab sab nraum cov nroj tsuag
Cov dej khib nyiab los ntawm tag nrho cov qhov hluav taws xob tawm ntawm tag nrho cov nroj tsuag yog kho nyob rau theem pib lossis theem nrab ua ntej nws tawm mus rau hauv lub cev dej, lossis cov dej khib nyiab siv rau kev siv dej thiab cov av thiab cov nroj tsuag yog siv los ntxuav cov dej khib nyiab. Kev kho thawj zaug feem ntau tshem tawm cov teeb meem tshem tawm, nrog rau txoj hauv kev xws li sedimentation thiab pom thiab huab cua flotation. Cov nroj tsuag ib tus neeg ntxiv flocculants rau cov dej khib nyiab kom tshem tawm qee yam ntawm cov khoom siv colloidal yaj, xws li lignin thiab pigments. Kev kho thawj zaug tuaj yeem tshem tawm 80 ~ 90% SS thiab 20% BOD5. Kev kho mob thib ob rau kev kho mob biochemical, feem ntau yog tshem tawm BOD5. Tuam Tshoj muaj ob peb cov nroj tsuag tau siv rau txoj kev no, suav cov pas dej oxidation, biofilters, bio-turntable thiab activated sludge (xws li adsorption thiab regeneration, accelerated aeration, hu rau oxidation). Kev kho mob theem nrab tuaj yeem tshem tawm 60 ~ 95% BOD5. industrial tsim lub teb chaws, muaj ib tug neeg cov nroj tsuag rau dej khib nyiab tertiary decolourisation thiab purification kev kho mob, thiaj li mus txog rau theem ntawm cov dej haus, tab sis tus nqi yog kim.
Yashi daim ntawv tso quav yog 100% tsis siv tshuaj chiv thiab tshuaj tua kab. Tag nrho cov txheej txheem siv lub cev pulping thiab non-bleaching tshuab los xyuas kom meej tias tsis muaj tshuaj lom thiab tsim kev puas tsuaj xws li tshuaj lom neeg, tshuaj tua kab, hlau hnyav, thiab lwm yam. Nws tau raug kuaj los ntawm lub koom haum soj ntsuam thoob ntiaj teb lees paub SGS thiab tsis muaj tshuaj lom thiab teeb meem cov ntsiab lus thiab carcinogens. Siv Nws muaj kev nyab xeeb dua thiab cov neeg siv khoom muaj kev ruaj ntseg ntau dua.
