Kev tiv thaiv thiab tswj kev ua qias tuaj hauv cov txheej txheem ua ntawv so quav tuaj yeem muab faib ua ob pawg: kev kho mob hauv Hoobkas thiab kev kho dej khib nyiab sab nraud.
Kev kho mob hauv cov nroj tsuag
Xws li: ① txhawb kev npaj (hmoov av, av nplaum, tev tawv, pith, thiab lwm yam), siv cov dej zaj duab xis plua plav collector, txo cov plua plav paug hauv kev npaj ua haujlwm, sau cov khib nyiab, rov qab los ntawm lub zog thermal, xws li siv cov tawv ntoo, cov ntoo chips, cov nyom burner boiler; ② txuag dej, rov ua dua dej dawb, ntau zaus dej rov qab siv dua; ③ txhim kho kev rho tawm ntawm cov dej haus dub ua noj, txhawb kev tswj hwm ntawm qhov chaw ntxuav tam sim no kom nce tus lej ntawm cov ntu, txo cov dej haus dub ua noj nrog cov pulp coj tawm ntawm kev ntxuav, thiab siv cov kua dej ua noj zoo meej rov qab los ntawm cov tshuaj lom neeg thiab cov thev naus laus zis thermal zog, xws li kev rov qab los ntawm alkali, thiab lwm yam kua dej pov tseg siv dav dav. Thiab siv cov tshuaj lom neeg thiab cov thev naus laus zis thermal zog zoo meej, xws li kev rov qab los ntawm alkali, nrog rau lwm yam kev siv dav dav ntawm cov thev naus laus zis pov tseg; ④ chlorine dioxide lossis oxy-alkali bleaching, lossis hydrogen peroxide bleaching, txhawm rau txo cov dej khib nyiab lignin chloride, chlorophenol thiab lwm yam tshuaj lom; ⑤ cov dej qias neeg uas tau lim los ntawm cov pa dej kom rov siv dua kom txo cov pa phem ntawm cov dej khib nyiab uas txo cov sulfur thiab cov organic uas yaj tau; ⑥ sau cov dej ntws thiab cov dej dub uas ntws, kua ntsuab, kua dawb, nrog rau kev tswj hwm lub khoos phis tawj hluav taws xob los ntsuas nws cov concentration, xa rov qab mus rau lub tank percussion, kom txo cov pa phem; ⑦ rov qab tau cov fibers uas ploj lawm, txo cov ntsiab lus ntawm cov khoom seem hauv cov dej khib nyiab; ⑧ txhim kho kev rov qab tau cov xab npum turpentine sulphate, txo cov pa phem ntawm cov tshuaj lom; ⑨ kho cov khib nyiab khov, siv cov combustion los rov qab tau cua sov, siv dav dav thiab sau cov qhov ntawm peb hom kev kho mob; ⑩ kho cov plua plav, siv tau rau hauv kev tshem tawm cov plua plav hluav taws xob, tshem tawm cov plua plav zaj duab xis dej thiab cov khoom siv cais cua daj cua dub thiab lwm yam khoom siv; kev ua pa phem Separator thiab lwm yam khoom siv; kev kho pa phem, sau cov pa phem hauv txhua lub chaw ua haujlwm, suav nrog cov pa phem uas tau tsa los ntawm cov pa dej qias neeg, tom qab txias, qhuav dej, tiv thaiv kev tawg thiab lwm yam kev ntsuas, xa mus rau lub boiler, lub cub tawg alkali lossis kev kho combustion kiln lime;? Kev kho suab nrov, ua cov kauj ruam los tshem tawm kev co, rwb thaiv suab thiab hloov mus rau cov khoom siv suab qis.
Kev kho dej khib nyiab sab nraum lub Hoobkas
Cov dej khib nyiab los ntawm tag nrho cov nroj tsuag raug kho ntawm theem pib lossis theem ob ua ntej nws raug tso tawm mus rau hauv dej, lossis cov dej khib nyiab siv rau kev ywg dej thiab av thiab cov nroj tsuag raug siv los ntxuav cov dej khib nyiab. Kev kho thawj zaug feem ntau tshem tawm cov khoom uas raug tshem tawm, nrog rau cov txheej txheem xws li kev tso dej thiab kev lim dej thiab kev ua kom huab cua ntab. Cov nroj tsuag ib leeg ntxiv cov flocculants rau hauv cov dej khib nyiab kom tshem tawm qee cov organic colloidal uas yaj, xws li lignin thiab pigments. Kev kho thawj zaug dav dav tuaj yeem tshem tawm 80 ~ 90% SS thiab 20% BOD5. Kev kho thib ob rau kev kho biochemical, feem ntau yog tshem tawm BOD5. Tuam Tshoj muaj ob peb tsob nroj tsuag tau siv rau txoj kev no, suav nrog cov pas dej oxidation, biofilters, bio-turntable thiab cov sludge ua haujlwm (suav nrog kev nqus thiab rov ua dua tshiab, kev ua kom nrawm dua, kev sib cuag oxidation). Kev kho thib ob dav dav tuaj yeem tshem tawm 60 ~ 95% BOD5. Cov teb chaws tsim kev lag luam, muaj cov nroj tsuag ib leeg rau cov dej khib nyiab tertiary decolorisation thiab kev kho kom huv, kom mus txog qib dej haus, tab sis tus nqi kim heev.
Daim ntawv so quav Yashi yog 100% tsis siv tshuaj chiv thiab tshuaj tua kab. Tag nrho cov txheej txheem siv cov tshuab pulping lub cev thiab cov tshuab tsis dawb kom ntseeg tau tias tsis muaj cov tshuaj lom thiab cov khoom phom sij xws li tshuaj lom neeg, tshuaj tua kab, cov hlau hnyav, thiab lwm yam. Nws tau raug sim los ntawm lub koom haum kuaj mob thoob ntiaj teb SGS thiab tsis muaj cov khoom lom thiab cov khoom phom sij thiab cov carcinogens. Siv nws muaj kev nyab xeeb dua thiab cov neeg siv khoom ntseeg siab dua.
