ʻO ka wai ʻōpala ʻo Textile ka wai ʻōpala i loaʻa i nā haumia kūlohelohe, nā momona, ka starch a me nā mea ola ʻē aʻe i hana ʻia i ka wā o ke kaʻina hana o ka kuke ʻana, holoi, bleaching, sizing, etc. ana, a pela aku, a he nui na mea olaola e like me ke kala, starch, cellulose, lignin, detergents, a me na mea anoano like ole alkali, sulfide, a me na paakai like ole, he mea haumia loa.
Nā hiʻohiʻona o ka paʻi ʻana a me ka waiho ʻana i ka wai ʻino
ʻO ka paʻi textile a me ka ʻoihana hoʻoluʻu he mea hoʻokuʻu nui i ka wai ʻino ʻoihana. Loaʻa i ka wai ʻōpala ka lepo, ka momona, nā paʻakai ma nā fiber textile, a me nā slurries like ʻole, dyes, surfactants, additives, acids a me alkalis i hoʻohui ʻia i ka wā o ke kaʻina hana.
ʻO nā hiʻohiʻona o ka wai ʻōpala he kiʻekiʻe o ka organic concentrate, complex composition, deep and variable chromaticity, nui ka hoʻololi ʻana o ka pH, nā loli nui i ka nui o ka wai a me ka maikaʻi o ka wai, a he paʻakikī ke mālama ʻana i ka wai ʻōpala ʻoihana. Me ka hoʻomohala ʻana o nā lole fiber kemika, ka piʻi ʻana o ka siliki hoʻohālikelike a me ka hoʻomaikaʻi ʻana i nā koi o ka paʻi ʻana a me ka hoʻopau ʻana i nā koi, ua komo ka nui o nā mea kūlohelohe refractory e like me ka PVA slurry, rayon alkaline hydrolyzate, nā mea hou a me nā mea kōkua i komo i ka textile. ka pa'i 'ana a me ka waiho 'ana i ka wai 'ino, he mea pa'akikī ko'iko'i i ke ka'ina hana wai 'ino. Ua hoʻonui pū ʻia ka manaʻo COD mai nā haneli milligrams i ka lita i 3000-5000 mg / l.
He chroma kiʻekiʻe a me ka COD kiʻekiʻe ka slurry a me ka wai kala ʻia, ʻoi aku ka maikaʻi o ka paʻi ʻana a me ke kala ʻana e like me ka mercerized blue, mercerized black, extra dark blue, a me ka ʻeleʻele ʻeleʻele i kūkulu ʻia e like me ka mākeke haole. Ke hoʻohana nei kēia ʻano paʻi a hoʻoluʻu i ka nui o nā mea sulfur a me nā mea kōkua paʻi a me ka wai e like me ka sodium sulfide. No laila, nui ka sulfide i loko o ka wai ʻōpala. Pono e mālama mua ʻia kēia ʻano wai ʻino me nā lāʻau lapaʻau a laila e hoʻopaʻa ʻia i ka mālama serial e hoʻokō paʻa i nā kūlana hoʻokuʻu. Aia i loko o ka wai ʻino ka bleaching a me ka waihoʻoluʻu ʻana i nā wai waihoʻoluʻu, slurries, surfactants a me nā mea kōkua ʻē aʻe. Nui ka nui o kēia ʻano wai ʻino, a ʻoi aku ka haʻahaʻa a me ka chromaticity. Inā hoʻohana wale ʻia ka mālama kino a me ke kemika, aia ka effluent ma waena o 100 a me 200 mg / l, a hiki i ka chromaticity ke hoʻokō i nā koi hoʻokuʻu, akā ua hoʻonui nui ʻia ka nui o ka pollution, kiʻekiʻe ke kumukūʻai o ka mālama ʻana i ka sludge. maʻalahi ka hoʻohaumia lua.

ʻano lāʻau lapaʻau kemika
ʻO ke ʻano coagulation
Loaʻa ka nui o ke ʻano sedimentation hui a me ke ʻano flotation hui. ʻO nā coagulants i hoʻohana ʻia he mau paʻakai aluminika a i ʻole paʻakai hao. Ma waena o lākou, ʻoi aku ka maikaʻi o ka alumini chloride (PAC) i ka hoʻokō adsorption, a ʻo ke kumukūʻai o ka ferrous sulfate ka haʻahaʻa loa. Ke piʻi nei ka nui o ka poʻe e hoʻohana ana i nā coagulants polymer ma waho, a aia ke ʻano o ka hoʻololi ʻana i nā coagulants inorganic, akā ma Kina, ma muli o nā kumu kumu kūʻai, ʻaʻole mau ka hoʻohana ʻana i nā coagulants polymer. Ua hōʻike ʻia ʻo nā coagulants anionic polymer nāwaliwali ka laulā o ka hoʻohana. Inā hoʻohana pū ʻia me ka alumini sulfate, hiki iā lākou ke pāʻani i kahi hopena maikaʻi aʻe. ʻO nā mea maikaʻi nui o ke ʻano hui ʻia he kahe kaʻina hana maʻalahi, ka hana maʻalahi a me ka hoʻokele ʻana, ka hoʻopukapuka haʻahaʻa haʻahaʻa, ka wāwae liʻiliʻi, a me ka maikaʻi decolorization kiʻekiʻe no nā wai hydrophobic; ʻO nā mea pōʻino he kiʻekiʻe nā kumukūʻai hana, ka nui o ka lepo a me ka paʻakikī i ka dehydration, a me ka hopena maikaʻi ʻole o ka lāʻau hydrophilic.
ʻO ke ʻano hoʻokahe
Hoʻohana nui ʻia ke ʻano o ka Ozone oxidation ma waho. Zima SV et al. hōʻuluʻulu ʻia ke ʻano makemakika o ka decolorization ozone o ka paʻi ʻana a me ke kala ʻana i ka wai ʻino. Ua hōʻike ʻia nā haʻawina i ka wā o ka ozone dosage he 0.886gO3/g dye, hiki i ka 80% ka decolorization rate o ka wai ʻōpala ʻulaʻula māmā; ʻike pū ka haʻawina ʻoi aku ka nui o ka ozone e pono ai no ka hana mau ʻana ma mua o ka mea e pono ai no ka hana intermittent, a ʻo ka hoʻokomo ʻana i nā ʻāpana i loko o ka reactor hiki ke hoʻemi i ka nui o ka ozone ma 16.7%. No laila, i ka hoʻohana ʻana i ka decolorization ozone oxidation, pono e hoʻolālā i kahi reactor intermittent a noʻonoʻo e hoʻokomo i nā ʻāpana i loko. Hiki ke hoʻokō i ka hopena decolorization maikaʻi no ka hapa nui o nā kala, akā maikaʻi ka hopena decolorization no nā wai hiki ʻole ke hoʻoheheʻe ʻia e like me ka sulfide, hōʻemi, a me nā uhi. I ka hoʻoholo ʻana mai ka ʻike hana a me nā hopena ma ka home a me nā ʻāina ʻē, he hopena decolorization maikaʻi kēia ʻano, akā hoʻopau ia i ka nui o ka uila, a paʻakikī ke hoʻolaha a hoʻohana iā ia ma kahi ākea. He kiʻekiʻe ka decolorization kiʻekiʻe o ke ʻano photooxidation no ka mālama ʻana i ka paʻi ʻana a me ke kala ʻana i ka wai ʻino, akā pono e hoʻemi hou ʻia ka hoʻokomo ʻana o nā lako a me ka hoʻohana ʻana i ka mana.
Keʻano electrolysis
He hopena maikaʻi ka Electrolysis i ka mālama ʻana i ka paʻi ʻana a me ke kala ʻana i ka wai ʻōpala i loaʻa i nā waiʻawaʻawa, me ka helu decolorization o 50% a 70%, akā maikaʻi ka hopena o ka mālama ʻana i ka wai me ka waihoʻoluʻu ʻeleʻele a me ka CODcr kiʻekiʻe. Hōʻike nā haʻawina e pili ana i nā waiwai electrochemical o nā mea hoʻonaninani i ke ʻano o ka wehe ʻana o CODcr i nā kala like ʻole i ka wā o ka mālama ʻana i ka electrolytic: nā sulfur dyes, hōʻemi i nā dyes> acid dyes, active dyes> neutral dyes, direct dyes> cationic dyes, a ke hāpai ʻia nei kēia ala. a noi.
He aha nā hōʻailona e hoʻāʻo ʻia no ka paʻi ʻana a me ke kala ʻana i ka wai ʻino
1. ʻIke COD
ʻO COD ka pōkole o ka koi oxygen kemika i ka paʻi ʻana a me ke kala ʻana i ka wai ʻino, e hōʻike ana i ka nui o ka oxygen kemika e pono ai no ka oxidation a me ka decomposition o nā mea organik a me nā mea ʻole i ka wai ʻino. Hiki i ka ʻike COD ke hōʻike i ka ʻike o nā mea ola i loko o ka wai ʻino, he mea nui ia no ka ʻike ʻana i ka ʻike o nā mea organik i ka paʻi ʻana a me ka hoʻoluli ʻana i ka wai ʻino.
2. ʻIke BOD
ʻO BOD ka pōkole o ka koi oxygen biochemical, e hōʻike ana i ka nui o ka oxygen e koi ʻia i ka wā e hoʻoheheʻe ʻia ai nā mea organik i ka wai ʻino e nā microorganism. Hiki i ka ʻike BOD ke noʻonoʻo i ka ʻike o ka mea ola i ka paʻi ʻana a me ka hoʻoluli ʻana i ka wai ʻino i hiki ke hoʻohaʻahaʻa ʻia e nā microorganism, a ʻoi aku ka pololei o ke ʻano o ka ʻike o ka mea ola i loko o ka wai ʻino.
3. ʻIke Chroma
ʻO ka waihoʻoluʻu o ka paʻi ʻana a me ke kala ʻana i ka wai ʻino he mea hoʻoikaika i ka maka o ke kanaka. Hiki i ka ʻike Chroma ke hōʻike i ke kiʻekiʻe o ka chroma i loko o ka wai ʻino a loaʻa kahi wehewehe kikoʻī o ke kiʻekiʻe o ka haumia i ka paʻi ʻana a me ke kala ʻana i ka wai ʻino.
4. ʻike waiwai pH
ʻO ka waiwai pH kahi hōʻailona koʻikoʻi e ʻike ai i ka acidity a me ka alkalinity o ka wai ʻino. No ka mālama olaola, ʻoi aku ka hopena o ka waiwai pH. Ma ka ʻōlelo maʻamau, pono e mālama ʻia ka waiwai pH ma waena o 6.5-8.5. ʻO ke kiʻekiʻe a i ʻole ka haʻahaʻa loa e pili ana i ka ulu a me nā hana metabolic o nā mea ola.
5. ʻIke ʻia ʻo Ammonia nitrogen
He hōʻailona maʻamau ka Ammonia nitrogen i ka paʻi ʻana a me ka hoʻoluli ʻana i ka wai ʻino, a ʻo ia kekahi o nā hōʻailona koʻikoʻi. ʻO ia ka huahana o ka hoʻoheheʻe ʻana o ka nitrogen organik a me ka nitrogen inorganic i loko o ka ammonia i ka paʻi ʻana a me ka hoʻoluli ʻana i ka wai ʻino. ʻO ka nui o ka ammonia nitrogen e alakaʻi i ka hōʻiliʻili o ka nitrogen i loko o ka wai, kahi maʻalahi e hoʻoulu i ka eutrophication o nā kino wai.
6. Huina phosphorus ike
He paʻakai koʻikoʻi ka phosphorus i ka paʻi ʻana a me ka waiho ʻana i ka wai ʻino. ʻO ka nui o ka phosphorus e alakaʻi i ka eutrophication o nā kino wai a pili i ke olakino o nā kino wai. ʻO ka nui o ka phosphorus i ka paʻi ʻana a me ka hoʻoluli ʻana i ka wai ʻino mai nā mea pena, nā mea kōkua a me nā mea kemika ʻē aʻe i hoʻohana ʻia i ke kaʻina paʻi a me ke kala.
I ka hōʻuluʻulu ʻana, ʻo nā ʻōkuhi nānā o ka paʻi ʻana a me ka waiho ʻana i ka wai ʻino e uhi nui i ka COD, BOD, chromaticity, pH value, ammonia nitrogen, total phosphorus a me nā mea ʻē aʻe. Ma ka hoʻāʻo piha ʻana i kēia mau hōʻailona a me ka mālama pono ʻana iā lākou e hiki ai ke hoʻomalu pono ʻia ka haumia o ka paʻi ʻana a me ka hoʻoluli ʻana i ka wai ʻino.
He mea hana ʻo Lianhua me 40 mau makahiki o ka ʻike i ka hana ʻana i nā mea hana hoʻāʻo wai. He mea kūikawā i ka hoʻolako ʻana i ka hale hanaCOD, naikokene ammonia, phosphorus a pau, naikokene piha,BOD, metala kaumaha, mea anoano a me na mea hana hoao. Hiki i nā mea kani ke hana wikiwiki i nā hopena, maʻalahi ka hana, a loaʻa nā hopena pololei. Hoʻohana nui ʻia lākou i nā ʻoihana like ʻole me ka hoʻohemo wai.
