Nui nā ʻano o nā flocculants, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana, ʻo kekahi he flocculants inorganic a ʻo kekahi he flocculants organik.
(1) Nā paʻakai paʻakai ʻole: ʻelua ʻano paʻakai metala, paʻakai hao a me nā paʻakai aluminika, a me nā paʻakai polymer inorganic e like mepolyaluminum chloride. ʻO nā mea maʻamau: ferric chloride, ferrous sulfate, ferric sulfate, alumini sulfate (alum), kumu alumini chloride, etc.
(2) Organic flocculants: nui nā mea polymer e like me polyacrylamide. No ka mea, loaʻa i nā polymer flocculants nā pono o: liʻiliʻi liʻiliʻi, wikiwiki sedimentation rate, kiʻekiʻe floc ikaika, a me ka hiki ke hoʻonui i ka wikiwiki kānana, ʻoi aku ka nui o kona hopena flocculation ma mua o nā flocculants inorganic kahiko, no laila ua hoʻohana nui ʻia i kēia manawa. i nā papahana hoʻomaʻemaʻe wai.
（Ka mea hana ʻoihana hoʻomaʻemaʻe wai ʻoihana-Ka wai maʻemaʻe honua）
Polymer flocculant--polyacrylamide
ʻO ka mea maka nui opolyacrylamide (PAM no ka pōkole)he acrylonitrile. Hoʻohui ʻia me ka wai i kekahi ʻāpana a loaʻa ma o ka hydration, hoʻomaʻemaʻe, polymerization, maloʻo a me nā kaʻina hana ʻē aʻe.
Hiki ke unuhi ʻia kēia mau hopena mai nā hoʻokolohua mua:
(1) ʻO Anionic PAM kūpono i nā mea i hoʻopaneʻe ʻia me ke kiʻekiʻe kiʻekiʻe a me ka hoʻopiʻi maikaʻi, a me nā mea i hoʻokuʻu ʻia (0.01~1mm), a me ka waiwai pH kūʻokoʻa a i ʻole alkaline.
(2) He kūpono ka Cationic PAM no nā mea i hoʻokuʻu ʻia me ka hoʻopiʻi maikaʻi ʻole a loaʻa nā mea olaola.
(3) Nonionic PAM kūpono no ka hoʻokaʻawale ʻana i nā mea i hoʻopaneʻe ʻia i loko o ke ʻano huila a me nā ʻano inorganic, a ʻo ka hopena he ʻakika a kū ʻole paha.
ʻO ka hoʻomākaukau ʻana i ka flocculant
Hiki i ka flocculant ke pae paʻa a i ʻole ka pae wai kiʻekiʻe. Inā hoʻopili pololei ʻia kēia flocculant i ka hoʻokuʻu ʻana, ma muli o kona kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻaʻole hiki ke hoʻopuehu maikaʻi ʻia ka flocculant i loko o ka hoʻokuʻu ʻana, e hopena i kahi hapa o ka flocculant ʻaʻole hiki ke pāʻani i kahi kuleana flocculant, e hopena i ka pau ʻana o ka flocculant. . No laila, pono ka mea hui hoʻoheheʻe e hoʻoulu i ka flocculant a me ka nui o ka wai e hiki ai i kahi ʻano hoʻohālikelike, maʻamau ʻaʻole ʻoi aku ma mua o 4 ~ 5g / L, a i kekahi manawa ʻoi aku ka liʻiliʻi o kēia waiwai. Ma hope o ka hoʻoulu ʻana, hiki ke hoʻohana ʻia. ʻO ka manawa e hoʻoulu ai ma kahi o 1-2h.
Ma hope o ka hoʻomākaukau ʻana o ka polymer flocculant, ʻo 2 ~ 3d kona manawa kūpono. Ke lilo ka hopena i keʻokeʻo waiu, ʻo ia hoʻi, ua ʻino a pau ka hopena, a pono e hoʻōki koke.
ʻO ka pūʻulu amide o polyacrylamide i hana ʻia e Yixing Cleanwater Chemicals Co., Ltd. hiki ke pili me nā mea he nui, adsorb a hana i nā paʻa hydrogen. Hoʻokumu ʻia ka polyacrylamide kiʻekiʻe kiʻekiʻe i nā alahaka ma waena o nā ion adsorbed, hoʻopuka i nā flocs, a hoʻolalelale i ka sedimentation o nā ʻāpana, a laila e hoʻokō ai i ka pahuhopu hope o ka hoʻokaʻawale ʻana i ka wai. Aia nā ʻano anionic, cationic a me nā ʻano non-ionic. I ka manawa like, hiki i nā mea kūʻai ke hana i nā huahana o nā kikoʻī like ʻole
