Nui nā ʻano flocculants, hiki ke puʻunaue ʻia i ʻelua mau māhele, ʻo kekahi he flocculants inorganic a ʻo kekahi he flocculants organic.
(1) Nā flocculants inorganic: me ʻelua ʻano paʻakai metala, nā paʻakai hao a me nā paʻakai alumini, a me nā flocculants polymer inorganic e like mepolyaluminum chlorideʻO nā mea i hoʻohana pinepine ʻia: ferric chloride, ferrous sulfate, ferric sulfate, aluminum sulfate (alum), basic aluminum chloride, etc.
(2) Nā flocculants organik: ʻo nā mea polymer nui e like me ka polyacrylamide. No ka mea, he mau pono ko nā flocculants polymer: ka liʻiliʻi o ka dosage, ka wikiwiki o ka sedimentation, ka ikaika floc kiʻekiʻe, a me ka hiki ke hoʻonui i ka wikiwiki o ka kānana, ʻoi aku ka nui o kona hopena flocculation ma mua o nā flocculants inorganic kuʻuna, no laila ua hoʻohana nui ʻia i kēia manawa i nā papahana mālama wai.
（Mea hana ʻoihana hoʻomaʻemaʻe wai-Clean Water clean world）
ʻO ka flocculant polymer--polyacrylamide
ʻO ka mea maka nui opolyacrylamide (PAM no ka pōkole)he acrylonitrile. Hoʻohui ʻia me ka wai ma kahi ʻāpana a loaʻa ma o ka hydration, purification, polymerization, drying a me nā kaʻina hana ʻē aʻe.
Hiki ke huki ʻia nā hopena ma lalo nei mai nā hoʻokolohua ma mua:
(1) He kūpono ka Anionic PAM no nā mea hoʻokuʻu inorganic me ke kiʻekiʻe o ka noʻonoʻo a me ka hoʻopiʻi maikaʻi, a me nā ʻāpana hoʻokuʻu coarse (0.01 ~ 1mm), a me ka waiwai pH neutral a alkaline paha.
(2) He kūpono ka PAM Cationic no nā mea i hoʻokuʻu ʻia me ka hoʻopiʻi maikaʻi ʻole a loaʻa nā mea olaola.
(3) He kūpono ka PAM Nonionic no ka hoʻokaʻawale ʻana i nā mea i hoʻokuʻu ʻia i ke ʻano hui like ʻole o nā mea olaola a me nā mea ʻole, a he waikawa a kūlike ʻole paha ka hopena
Ka hoʻomākaukau ʻana o ka flocculant
Hiki i ka flocculant ke lilo i pae paʻa a i ʻole ka pae wai kiʻekiʻe. Inā hoʻohui pololei ʻia kēia flocculant i ka hoʻokuʻu ʻia, ma muli o kona nui kiʻekiʻe a me ka wikiwiki hoʻolaha haʻahaʻa, ʻaʻole hiki ke hoʻopuehu maikaʻi ʻia ka flocculant i loko o ka hoʻokuʻu ʻia, e hopena ana i kahi hapa o ka flocculant ʻaʻole hiki ke pāʻani i kahi hana flocculation, e hopena ana i ka hoʻonele ʻana o ka flocculant. No laila, pono kahi mea hoʻohuihui hoʻoheheʻe e hoʻoulu i ka flocculant a me kahi nui kūpono o ka wai e hiki ai i kahi ʻano nui, ʻaʻole ma mua o 4 ~ 5g / L, a i kekahi manawa emi ma mua o kēia waiwai. Ma hope o ka hoʻoulu like ʻana, hiki ke hoʻohana ʻia. ʻO ka manawa hoʻoulu ma kahi o 1 ~ 2h.
Ma hope o ka hoʻomākaukau ʻana o ka flocculant polymer, ʻo kona manawa kūpono he 2 ~ 3d. Ke lilo ka wai i keʻokeʻo waiū, ʻo ia hoʻi ua pala ka wai a ua pau ka manawa, a pono e hoʻōki koke ʻia.
ʻO ka hui amide o ka polyacrylamide i hana ʻia e Yixing Cleanwater Chemicals Co., Ltd. hiki ke pili me nā mea he nui, adsorb a hana i nā pilina hydrogen. ʻO ka polyacrylamide kaumaha molekala kiʻekiʻe e hana i nā alahaka ma waena o nā ions adsorbed, hana i nā flocs, a hoʻolalelale i ka sedimentation o nā ʻāpana, a laila e hoʻokō ai i ka pahuhopu hope loa o ka hoʻokaʻawale ʻana o ka wai paʻa. Aia nā ʻano anionic, cationic a me nā non-ionic. I ka manawa like, hiki i nā mea kūʻai ke hoʻopilikino i nā huahana o nā kikoʻī like ʻole.
ʻŌlelo Hoʻokuʻu: Mālama mākou i kahi ʻano kūlike ʻole i nā manaʻo o ka ʻatikala. No ka ʻike wale nō kēia ʻatikala, no ke kamaʻilio ʻana, ʻaʻole no ke kālepa ʻana, a no ka mea kākau mua ke kuleana kope. Mahalo no kou nānā ʻana a me ke kākoʻo!
