Polyaluminum Chloride (PAC)
ʻO ka Polyaluminum chloride (PAC), i kapa ʻia he polyaluminum no ka pōkole, Poly Aluminum Chloride dosing In Water Treatment, loaʻa ke ʻano kemika Al₂Cln(OH)₆-n. ʻO ka Polyaluminum Chloride Coagulant kahi mea mālama wai polymer inorganic me ke kaumaha molekala nui a me ka uku kiʻekiʻe i hana ʻia e ka hopena bridging o nā ion hydroxide a me ka polymerization o nā anion polyvalent. Hiki ke hoʻokaʻawale ʻia ka Poly Aluminum Chloride Pac i ka paʻa a me ka wai i ke ʻano. Polyaluminum paʻa Melemele, hina-'ōmaʻomaʻo, ʻeleʻele ʻeleʻele pauda. Hiki ke hoʻopili ʻia ka wai Pac e ka makū a hiki ke hoʻoheheʻe ʻia i ka wai. Hoʻopili ʻia ke kaʻina hana hydrolysis me nā kaʻina hana kino a me nā kemika e like me ka electrochemistry, agglutination, adsorption, a me ka ua, a he mau waiwai bridging adsorption ikaika.
1. Mechanism o ka hana
ʻO ka hoʻonā wai o ka kemika PAC he huahana hydrolysis ma waena o FeCl₃ a me Al(OH)₃, me ka uku colloidal, no laila ua ikaika ka adsorption i nā mea paʻa i hoʻopaʻa ʻia i ka wai, i hiki ai ke hoʻokō i ke kumu o ka coagulating paʻa paʻa i ka wai.
2. Nā hiʻohiʻona huahana
● Polyaluminum chloride mea kemika paʻa i ka lumi wela, a e ole deteriorate ma hope o ka lōʻihi-makahiki mālama. ʻO ka polyaluminum paʻa i hōʻike ʻia e maʻalahi i ka makū, akā ʻaʻole e hōʻino ʻia, a ʻaʻohe mea ʻawaʻawa a maikaʻi ʻole.
● ʻO 4-14 ka waiwai pH o ka pae wai kūpono, akā ʻo 6-8 ka waiwai pH o ka pae lapaʻau maikaʻi loa.
● Poly Aluminum Chloride Powder i nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi, ke kumu kūʻai haʻahaʻa, ka hana kiʻekiʻe, ka hana maʻalahi, ka hoʻohana ākea a me ka corrosiveness haʻahaʻa.
Polyacrylamide (PAM)
Polyacrylamide (PAM) /nonionic polyacrylamide/cation polyacrylamide/anionic polyacrylamide, alias flocculant No. 3, he polymer linear hiki ke hoʻoheheʻe ʻia i ka wai i hana ʻia e ka polymerization radical manuahi o ka monomer acrylamide (AM). ʻO ka coagulation a me ka flocculation kaʻina i ka mālama wai, Polyacrylamide sds he flocculation maikaʻi a hiki ke hōʻemi i ka friction ma waena o nā wai Hiki ke hoʻokaʻawale ʻia ke kū'ē i ʻehā mau ʻano: anionic, cationic, nonionic a me amphoteric e like me nā waiwai ionic.
ʻO ka polyacrylamide kahi ʻāpana pauka keʻokeʻo, hiki ke hoʻoheheʻe ʻia i loko o ka wai i kēlā me kēia ʻāpana, ʻokoʻa a ʻike ʻia ka wai aqueous, a piʻi nui ka viscosity o ka hoʻonā wai me ka piʻi ʻana o ke kaumaha molekala pili o ka polymer. ʻAʻole hiki ke hoʻoheheʻe ʻia ka PAM i ka hapa nui o nā mea hoʻoheheʻe organik, e like me formaldehyde, ethanol, acetone, ether, etc.
1. Mechanism o ka hana
ʻO ka polyacrylamide he polymer hiki ke hoʻoheheʻe ʻia i ka wai a i ʻole polyelectrolyte. Aia kekahi helu o nā pūʻulu polar i loko o ke kaulahao mole PAM, hiki iā ia ke hoʻopili i nā ʻāpana paʻa i hoʻokuʻu ʻia i loko o ka wai, hana i nā alahaka ma waena o nā ʻāpana a i ʻole ma o ka hoʻokaʻawale ʻana, i hiki ai i nā ʻāpana ke agglomerate e hana i nā flocs nui. No laila, hiki i ka polyacrylamide ke hoʻolalelale i nā paʻa paʻa. ʻO ka hoʻoheheʻe ʻia ʻana o nā ʻāpana liʻiliʻi he hopena maopopo loa o ka wikiwiki ʻana i ka wehewehe ʻana o ka hopena a me ka hoʻoikaika ʻana i ka kānana.
2. Nā memo
Loaʻa i ka polyacrylamide ka monomer acrylamide ʻona. I loko o ka mālama wai inu i ʻōlelo ʻia ma koʻu ʻāina, ʻo ka nui i ʻae ʻia ʻo 0.01mg/L. I mea e pale aku ai i ka hoʻohaʻahaʻa ʻana o ka polyacrylamide, pono e mālama ʻia ka mahana mālama o kāna ʻano wai ʻaʻole i kiʻekiʻe ma mua o 40 ° C. I mea e pale aku ai i ka ʻike ʻana i ka lā, hiki ke hoʻohui ʻia kahi mea hoʻopaʻa liʻiliʻi, e like me ka sodium thiocyanate, sodium nitrite, etc., i ka hopena. Pono e hoʻopili ʻia ka pauka paʻa polyacrylamide i loko o nā pahu hao i uhi ʻia me nā ʻeke polyethylene i hoʻopaʻa ʻia i ka wai a i ʻole i hoʻopaʻa ʻia me nā papa polyethylene, a hoʻopaʻa ʻia i mea e pale ai i ka ʻike ʻana i ka haʻahaʻa kiʻekiʻe.
Pono e hoʻopili ʻia ka polyacrylamide wai a laila waiho ʻia i loko o nā pahu lāʻau a i ʻole nā pahu hao. ʻO ka manawa mālama ma kahi o 3 a 6 mau mahina. Pono e hoʻoulu ʻia ma mua o ka hoʻohana ʻana. ʻAʻole pono ke kiʻekiʻe o ka mahana mālama ma mua o 32 ° C a ma lalo o 0 ° C.
