Zida zosindikizira ndi zopaka utoto wamadzi otayiraimapangidwa makamaka ndikupangidwira kusindikiza ndi kudaya madzi oyipa okhala ndi chromaticity yayikulu komanso kuvutikira kwa decolorization, ndi COD yapamwamba, yomwe imatha kuthana ndi zovuta zaukadaulo zomwe zidachitika kale kusindikiza ndi kudaya madzi oyipa.Madzi otayira osindikizira ndi opaka utoto amatha kutayidwa mpaka momwe amachitira pambuyo pa chithandizo.
Ubwino wa madzi osindikizira ndi kudaya madzi oipa amasiyanasiyana malinga ndi mtundu wa ulusi wogwiritsidwa ntchito ndi ukadaulo wokonza, ndipo zigawo zoipitsa zimasiyana kwambiri.Kusindikiza ndi kudaya madzi oyipa nthawi zambiri amakhala ndi mawonekedwe oipitsa kwambiri, mitundu ingapo, zinthu zapoizoni komanso zovulaza, komanso kusinthasintha kwakukulu.Nthawi zambiri, pH mtengo wa kusindikiza ndi kudaya madzi oipa ndi 6-10, CODCr ndi 400-1000mg/L, BOD5 ndi 100-400mg/L, SS ndi 100-200mg/L, ndipo chromaticity ndi 100-400 nthawi.
Koma njira yosindikizira ndi yopaka utoto, mitundu ya ulusi wogwiritsiridwa ntchito, ndi umisiri wokonza zinthu zikasintha, khalidwe la chimbudzi lidzakhala ndi kusintha kwakukulu.M'zaka zaposachedwapa, chifukwa cha chitukuko cha nsalu CHIKWANGWANI mankhwala, kukwera kwa silika kutsanzira, ndi kupita patsogolo kwa utoto ndi kutsiriza luso, chiwerengero chachikulu cha zovuta kuwononga organic mankhwala monga PVA kukula, alkali hydrolysates wa silika yokumba (makamaka phthalates). ), ndipo zowonjezera zatsopano zalowa m'madzi osindikizira ndi kudaya madzi oipa.Mlingo wa CODCr wawonjezekanso kuchokera ku mazana a mg/L mpaka kupitirira 2000-3000mg/L, BOD5 yawonjezeka kufika pa 800mg/L, ndipo pH mtengo wafika 11.5-12, Izi zimachepetsa CODCr kuchotsedwa kwa chithandizo choyambirira chachilengedwe. dongosolo kuchokera 70% mpaka 50%, kapena kutsika.
Kuchuluka kwa madzi otayira omwe amapangidwa posindikiza ndi kudaya madzi oyipa ndi ochepa, koma kuchuluka kwa zowononga ndizochulukirapo, zomwe zimakhala ndi makulidwe osiyanasiyana, zinthu zowola, tchipisi cha fiber, alkali wowuma, ndi zowonjezera zosiyanasiyana.Madzi amadzimadzi ndi amchere okhala ndi pH yamtengo wozungulira 12. Madzi otayira a deizing okhala ndi wowuma monga chotengera chachikulu (monga nsalu ya thonje) ali ndi ma COD apamwamba ndi ma BOD komanso kuwonongeka kwachilengedwe.Madzi onyansa okhala ndi mowa wa polyvinyl (PVA) monga chida chachikulu (monga ulusi wa thonje wa polyester) ali ndi COD yokwera komanso BOD yotsika, komanso kuwonongeka kwa madzi oyipa ndi koyipa.
Kusindikiza ndi kudaya madzi onyansa kumakhala ndi madzi ambiri otayira otentha owiritsa komanso zowononga zambiri, kuphatikizapo mapadi, citric acid, sera, mafuta, alkali, surfactants, mankhwala okhala ndi nayitrogeni, etc. mtundu wa bulauni.
Kusindikiza ndi kudaya madzi onyansa kumakhala ndi madzi ambiri otayira bleaching, koma kuipitsidwa kwake kumakhala kopepuka, komwe kumakhala ndi ma bleaching otsalira, acetic acid, oxalic acid, sodium thiosulfate, ndi zina zambiri.
Kusindikiza ndi kudaya madzi otayidwa ndi madzi onyansa okhala ndi alkali ambiri, okhala ndi NaOH kuyambira 3% mpaka 5%.Zomera zambiri zosindikizira ndi zopaka utoto zimapezanso NaOH kudzera mu nthunzi ndi kukhazikika, kotero kuti madzi oyipa a mercerizing nthawi zambiri satulutsa.Pambuyo pogwiritsidwa ntchito mobwerezabwereza, madzi otayira omaliza otayidwa akadali amchere kwambiri, okhala ndi BOD, COD, ndi SS.
Kuchuluka kwa madzi otayira opaka utoto posindikiza ndi kupaka utoto ndikokulirapo, ndipo mtundu wamadzi umasiyana malinga ndi utoto womwe umagwiritsidwa ntchito.Lili ndi slurries, utoto, zowonjezera, zowonjezera, ndi zina zotero, ndipo nthawi zambiri zimakhala zamchere zamphamvu zomwe zimakhala ndi chromaticity yayikulu.COD ndiyokwera kwambiri kuposa BOD, ndipo kuwonongeka kwake kwachilengedwe kumakhala kocheperako.
Kuchuluka kwa kusindikiza ndi kudaya madzi oyipa ndikokulirapo.Kuphatikiza pa madzi otayira kuchokera ku makina osindikizira, amaphatikizanso ndi sopo ndi madzi ochapira madzi otayira pambuyo posindikiza.Kuchuluka kwa zowononga ndizokwera, kuphatikiza slurry, utoto, zowonjezera, ndi zina zambiri, ndipo BOD ndi COD zonse ndizokwera.
Kuchuluka kwa madzi otayira kuchokera ku makina osindikizira ndi kudaya madzi onyansa ndi ochepa, omwe amakhala ndi ma fiber chips, resin, mafuta opangira mafuta, ndi slurries.
Kusindikiza ndi kudaya madzi oipa a alkali kuchepetsa madzi oipa amapangidwa kuchokera ku njira yochepetsera alkali ya silika wotsanzira wa polyester, makamaka okhala ndi polyester hydrolysates monga terephthalic acid ndi ethylene glycol, okhala ndi terephthalic acid okhutira mpaka 75%.Madzi otayira ochepetsa zamchere samangokhala ndi pH yamtengo wapatali (nthawi zambiri> 12), komanso amakhala ndi zinthu zambiri zachilengedwe.CODCr m'madzi onyansa otulutsidwa kuchokera mu njira yochepetsera alkali imatha kufika ku 90000 mg/L.Ma organic organic compounds ndi utoto wina ndizovuta kuti biodegrade, ndipo mtundu uwu wamadzi otayira amakhala wochulukira kwambiri ndipo ndi wovuta kutsitsa madzi oyipa achilengedwe.
Zida zosindikizira ndi zopaka utoto wamadzi otayira zimagwiritsa ntchito zochitika zamoyo za mabakiteriya a anaerobic ndi aerobic kudya zowononga zachilengedwe m'madzi oipa.Pa nthawi yomweyo, ndi tizilombo flocculent zopangidwa ndi tizilombo destabilize ndi flocculate inaimitsidwa ndi colloidal organic zoipitsa, adsorb padziko adamulowetsa sludge, kunyoza organic kanthu, ndipo potsirizira pake kukwaniritsa zotsatira za kuyeretsa madzi oipa.
Chidacho chimakhala ndi mpweya wapansi pamadzi, womwe umakankhidwa ndi kutuluka kwa madzi kuti apange aeration yapawiri.Poyeretsa zimbudzi, zimbudzi zimalowa m'dera la aeration kuchokera pamwamba pa chipangizocho, ndipo mpweya umadutsa pansi pa madzi ndikukankhira madzi kuti asokoneze chimbudzi.Madzi otayira omwe amalowa amasakanikirana mokwanira ndi kusakaniza koyambirira, kusinthasintha kusintha kwa khalidwe la madzi olowera mpaka momwe zingathere.Aerator imakhala ndi ntchito ziwiri zoyendetsera madzi komanso mpweya wapansi pamadzi, zomwe zimathandiza kuti zimbudzi zomwe zili m'dera la aeration ziziyenda pafupipafupi ndikuwonjezera mpweya wosungunuka m'chimbudzi.Chifukwa cha kuyendayenda kosalekeza ndi kutuluka kwa zimbudzi m'dera la aeration, khalidwe la madzi pa malo aliwonse a derali ndi lofanana, ndipo chiwerengero ndi katundu wa tizilombo toyambitsa matenda ndizofanana.Choncho, ntchito za gawo lililonse la dera la aeration zimakhala zofanana.Izi zimawongolera momwe biochemical zimayendera pansi pamikhalidwe yabwino komanso yofanana.Organic kanthu pang'onopang'ono amadetsedwa ndi tizilombo, ndipo madzi oipa amayeretsedwa.Kuchita bwino kwa kuyeretsa ndikwambiri, ndipo zisonyezo zonse zakunyalala zimakwaniritsa miyezo yapadziko lonse ya "Emission Standards for Pollutants in the Textile Dyeing and Finishing Industry" (GB 4267-92).Malinga ndi zomwe makasitomala amafuna, malo ena othandizira atha kuperekedwa kwa ozoni amphamvu oxidation kuyatsa kuti akwaniritse miyezo ya "Water Quality Standards for Urban Wastewater Recycling and Landscape Environment Water" (GB/T 18921-2002) miyezo yobwezeretsanso ndikugwiritsa ntchito. kukula kwa zida processing:
Izi Integrated kusindikiza ndi utoto zida mankhwala amadzi oipa ndi oyenera mankhwala osiyanasiyana mkulu, sing'anga, ndi otsika ndende kusindikiza ndi kudaya madzi zinyalala, monga lunited kusindikiza ndi utoto madzi oipa, utoto ubweya ndi kutsiriza madzi oipa, utoto silika ndi kutsiriza madzi oipa, mankhwala CHIKWANGWANI dyeing. ndi kumaliza madzi oipa, thonje wolukidwa ndi thonje wosakaniza nsalu ndi kumaliza madzi oipa.
