ʻO Polyacrylamide no ka mālama wai ʻino

Polyacrylamide (PAM), aka: flocculant, anion, cation,

polimer;Nā Polymers, ka hoʻopaʻa ʻana a me ka kānana AIDS, ka paʻa ʻana o ka AIDS, nā dispersants;Polymer, aila displacement agent, etc.

Nā kumu e pili ana i ka hopena o ka hoʻomaʻemaʻe wai:

1. He mea hiki ʻole ke ʻalo ʻia ka ʻōpala o ka hoʻomaʻemaʻe wai.ʻO ka mea mua, pono mākou e hoʻomaopopo i ke kumu, ke ʻano, ka haku ʻana a me ka ʻike paʻa o ka sludge.E like me ka hana nui o ka sludge, hiki ke hoʻokaʻawale ʻia ka sludge i ka sludge organik a me ka sludge inorganic.Ma ka ʻōlelo maʻamau, hoʻohana ʻia ka cationic polyacrylamide no ka mālama ʻana i ka sludge organik, hoʻohana ʻia ka anionic polyacrylamide no ka mālama ʻana i ka sludge inorganic.ʻAʻole maʻalahi ka hoʻohana ʻana i ka polyacrylamide cationic ke ikaika loa ka alkaline, a ʻaʻole kūpono ke hoʻohana i ka polyacrylamide anionic ke kiʻekiʻe ka ʻike paʻa o ka sludge.

2. Ion degere koho: no ka sludge e dehydrated, flocculant me ka okoa ion degere hiki ke kānana ma o ka liʻiliʻi hoʻokolohua e koho i ka polyacrylamide kūpono, i hiki ke hoʻokō i ka maikaʻi flocculant hopena, akā, hiki ke hana i ka mea liʻiliʻi, ke kumu kūʻai.

3. ʻO ka nui o nā flocs: ʻoi aku ka liʻiliʻi o nā flocs i ka wikiwiki o ka hoʻokahe ʻana, ʻoi aku ka nui o nā flocs i ka hui nui ʻana i nā flocs i hoʻopaʻa ʻia i ka wai a hoʻemi i ka degere biscuit lepo.Hiki ke hoʻololi ʻia ka nui o nā flocs ma ke koho ʻana i ke kaumaha mole o polyacrylamide.

4. ʻO ka ikaika o ka flocs: pono e noho paʻa nā flocs a ʻaʻole i haki ma lalo o ka hana ʻoki.ʻO ka hoʻonui ʻana i ke kaumaha o ka polyacrylamide a i ʻole ke koho ʻana i ke ʻano molekala kūpono e kōkua i ka hoʻomaikaʻi ʻana i ka paʻa o nā flocs.

5. ʻO ka hui ʻana o ka polyacrylamide a me ka sludge: polyacrylamide i kahi kūlana o ka mea hoʻoheheʻe wai pono e hoʻopiha piha ʻia me ka sludge, flocculation.No laila, pono e kūpono ka viscosity o ka solution polyacrylamide, a hiki ke hoʻohui piha ʻia me ka sludge ma lalo o nā kūlana lako.Inā hui like ʻia nā mea ʻelua, ʻo ia ke kumu nui o ka holomua.ʻO ka viscosity o ka solution cationic polyacrylamide e pili ana i kona kaumaha mole a me ka hoʻomākaukau ʻana.

6. ʻO ka hoʻoheheʻe ʻana o ka polyacrylamide cationic: hoʻoheheʻe maikaʻi e hāʻawi i ka pāʻani piha i ka flocculation.I kekahi manawa pono e hoʻolōʻihi i ka helu dissolution, i ka wā e noʻonoʻo ʻia ai ka neʻe ʻana o ka hopena polyacrylamide.
