Nā huaʻōlelo: Flocculant hoʻohemo kala, mea hoʻohemo kala, mea hana mea hoʻohemo kala
Ma ke kahua o ka mālama ʻana i ka wai ʻino ʻoihana,nā flocculants hoʻohemo kalahana e like me ke "kauka maikaʻi wai," e nānā pono ana a kuhikuhi i nā lāʻau lapaʻau no ka wai hoʻoneoneo mai nā ʻoihana like ʻole. Eia nō naʻe, he kumumanaʻo ko kēia kauka: ʻaʻole loa e "mālama" ma waho o kāna ʻoihana ponoʻī. No ke aha e hiki ʻole ai ke hoʻohana pololei ʻia nā mea hoʻoluʻu a me nā mea paʻi i nā hale wili pepa? No ke aha e hiki ʻole ai i nā ʻano hana hale hana meaʻai ke mālama i ka wai hoʻoneoneo electroplating? Ma hope o kēia aia ke "code ʻoihana" o ka mālama ʻana i ka wai hoʻoneoneo ʻoihana.
1. Nā "ʻOkoʻa Genetic" o ka Wai ʻŌpala ʻOihana
ʻO ka wai ʻino mai nā ʻoihana like ʻole e like me nā kānaka me nā ʻano koko like ʻole, e koi ana i ka hoʻohālikelike ʻana i ke "koko flocculant decolorizing." E lawe i ka hoʻoluʻu ʻana a me ka paʻi ʻana i ka wai ʻino ma ke ʻano he laʻana; loaʻa iā ia ka nui o nā mea olaola paʻakikī e like me nā dyes azo a me nā dyes reactive. Hoʻokumu kēia mau mea i nā colloids i hoʻopiʻi maikaʻi ʻole ʻia i loko o ka wai, e koi ana i nā mea hoʻoheheʻe cationic e hoʻopau i ka hoʻopiʻi a hoʻokō i ka decolorization. ʻO ka wai ʻino o ka wili pepa he lignin a me cellulose, a ʻokoʻa loa kona mau waiwai colloidal mai nā mea hoʻoluʻu. ʻO ka hoʻoikaika ʻana i ka hoʻohana ʻana i nā mea hoʻoluʻu i kēia hihia e like me ka hoʻāʻo ʻana e mālama i ka haki iwi me ka lāʻau anu - e emi nui ka hopena.
ʻO kahi laʻana maʻamau ka wai hoʻomaʻemaʻe meaʻai. Nui kēia ʻano wai hoʻomaʻemaʻe i nā mea olaola e like me ka protein a me ka starch, a ʻo kona waiwai pH he kūʻokoʻa a ʻakika iki paha. ʻO ka hoʻohana ʻana i nā flocculants decolorizing dyeing alkaline ikaika ʻaʻole wale ia e hiki ʻole ke hoʻomaʻemaʻe pono i ka wai hoʻomaʻemaʻe akā e luku pū i nā microorganisms maikaʻi, e alakaʻi ana i ka hiolo ʻana o nā kaʻina hana mālama olaola ma hope. Ua like kēia me ka hāʻawi hewa ʻana i ka adrenaline i kahi maʻi maʻi diabetes i ka wā e hoʻokomo ana i ka insulin - ʻaʻole hiki ke noʻonoʻo ʻia nā hopena.
2. "Hoʻohālikelike Pololei" o nā Palena ʻenehana
ʻO ka waiwai pH ke "kūlana gula" no ke koho ʻana i nā flocculants decolorizing. Ua hoʻohana pololei kahi hale hana kemika i kahi mea hoʻohemo kala mai ka wai hoʻoheheʻe electroplating (pH=2) ma ka wai hoʻoheheʻe lāʻau lapaʻau (pH=8), e hopena ana i ka hana ʻole o ka mea hana. ʻO kēia no ka mea e hoʻoheheʻe kahi ʻano waikawa ikaika i nā mea cationic, ʻoiai ʻo kahi ʻano alkaline e hiki ke hoʻoulu i ka ua o nā flocculants decolorizing anionic. He mea nui like ka mahana. ʻO ka hoʻohana ʻana i nā mea hana haʻahaʻa wela i loko o ka wai hoʻoheheʻe wela kiʻekiʻe (60℃) mai nā hale wili lole e hopena i nā flocs wehe a me ka noho lohi ʻana, e like me ka hoʻohana ʻana i ka hau e kuke ai i kahi ipu wela - he uhaki piha ʻana i nā kānāwai kino.
3. ʻO ka "Laina Lalo Pālua" o ka Hoʻokele Waiwai a me ka Palekana
ʻO ka hoʻohana ʻana i nā ʻākena ma nā ʻoihana like ʻole, ʻike ʻia paha he kūpono ke kumukūʻai, akā he nui nā pilikia. Hoʻokahi hui, i ka hoʻāʻo ʻana e mālama i ke kālā, ua hoʻohana i ka flocculant decolorizing o kahi hale hana ʻili no ka mālama ʻana i ka wai ʻino o ka haukapila, e hopena ana i ka nui o nā hoʻokuʻu metala kaumaha a me nā uku kaumaha mai nā luna kaiapuni. ʻOiai ʻoi aku ke kumukūʻai o nā ʻākena kūikawā, hiki i ka dosing pololei ke hōʻemi i ka hoʻohana ʻana ma 30%, e alakaʻi ana i ka hoʻohaʻahaʻa ʻana i nā kumukūʻai holoʻokoʻa. ʻOi aku ka mea nui, hiki i nā ʻākena i hana ʻia ke pale i ka haumia lua. ʻO kahi hale wili pepa, ma hope o ka hoʻohana ʻana i kahi flocculant decolorizing no ke kumu maʻamau, ua ʻike ʻo ia i ka COD nui i loko o kāna effluent, e koi ana iā ia e hoʻopukapuka i nā hale mālama holomua, a i ka hopena e pāpālua i kāna mau kumukūʻai.
4. ʻO nā "Palena Paʻa" o nā Kūlana ʻOihana
ʻO ke "Water Pollutant Discharge Standard for Textile Dyeing and Finishing Industry" e koi pono ana i ka hoʻohana ʻana i nā flocculants decolorizing kūikawā. ʻAʻole wale kēia he kikoʻī loea akā he kuleana kānāwai hoʻi. Ua papa inoa ʻeleʻele ʻia kahi ʻoihana dyeing a me ka paʻi ʻana e nā luna kaiapuni no ka hoʻohana hewa ʻana i nā kemika generic, e hopena pololei ana i nā kauoha nalowale. ʻO ka maʻamau, ua hōʻoia ʻia nā flocculants decolorizing kikoʻī o ka ʻoihana a loaʻa iā lākou nā hōʻike hoʻāʻo piha, ʻoiai ʻaʻole pinepine nā kemika generic i nā palapala hoʻokō, e hōʻike ana i nā pilikia kiʻekiʻe loa.
ʻAʻohe hopena "hoʻokahi-nui-kūpono-āpau" no ka mālama ʻana i ka wai ʻino ʻoihana; loaʻa i kēlā me kēia ʻanuʻu kona ʻano kū hoʻokahi. Mai nā ʻokoʻa o ke ʻano a me nā palena loea a hiki i nā kumukūʻai hoʻokele waiwai a me nā kuleana kānāwai, ʻōlelo kēlā me kēia ʻano i ka ʻoiaʻiʻo like: ʻaʻole pono e hui pū ʻia nā flocculants decolorizing mai nā ʻoihana like ʻole. ʻAʻole kēia he mea wale nō o ke koho ʻenehana, akā he mea hoʻi o ka mahalo i nā kānāwai kūlohelohe a me ke kūpaʻa i ke kaiapuni kaiaola. I ka wā e hiki mai ana, i ka wā e hoʻomaʻemaʻe nui ʻia ai ka māhele ʻoihana, ʻo ka hoʻopilikino a me ka loea e lilo ia i mea maʻamau i ka mālama ʻana i ka wai ʻino.
