He kūpono loa nā flocculants Polyacrylamide i ka hoʻohemo ʻana i ka sludge a me ka hoʻonoho ʻana i ka wai ʻino. Hōʻike kekahi mau mea kūʻai aku e hālāwai ka polyacrylamide pam i hoʻohana ʻia i ka hoʻohemo ʻana i ka sludge i nā pilikia like ʻole. I kēia lā, e kālailai wau i kekahi mau pilikia maʻamau no nā mea āpau. :
1. ʻAʻole maikaʻi ka hopena flocculation o ka polyacrylamide, a he aha ke kumu e hiki ʻole ai ke kaomi ʻia i loko o ka sludge? Inā ʻaʻole maikaʻi ka hopena flocculation, pono mua mākou e hoʻopau i nā pilikia maikaʻi o ka huahana flocculant ponoʻī, inā paha e kūlike ka polyacrylamide cationic i ke kūlana kaumaha molekala ionic, a ʻo ka hopena dewatering sludge o ka huahana i kū ʻole i ke kūlana ʻaʻole ia he maikaʻi. I kēia hihia, hiki i ka hoʻololi ʻana i ka PAM me kahi pae ion kūpono ke hoʻoponopono i ka pilikia.
2. He aha kaʻu e hana ai inā nui loa ka nui o ka polyacrylamide?
ʻO ka nui o ka nui, ʻo ia hoʻi, ʻaʻole lawa ka ʻike kuhikuhi o ka huahana, a aia kahi hakahaka ma waena o nā kuhikuhi e pono ai no ka polyacrylamide a me ka flocculation sludge. I kēia manawa, pono ʻoe e koho hou i ke ʻano, koho i ke kumu hoʻohālike PAM kūpono a me ka nui o ka hoʻohui e hoʻāʻo ai, a loaʻa kahi hoʻohana waiwai hou aku. kumukūʻai. Ma keʻano laulā, ua ʻōlelo ʻia ʻo ka nui o ka polyacrylamide i hoʻoheheʻe ʻia he hoʻokahi tausani a ʻelua tausani, a ua hana ʻia kahi koho hoʻāʻo liʻiliʻi e like me kēia ʻano, a ʻoi aku ka kūpono o nā hopena i loaʻa.
3.He aha kaʻu e hana ai inā kiʻekiʻe ka mānoanoa o ka sludge ma hope o ka hoʻohana ʻana i ka polyacrylamide i ka sludge dewatering?
ʻO kēia kūlana ma muli o ka hoʻohui nui ʻana o ka polyacrylamide a i ʻole ka huahana kūpono ʻole a me ka sludge. Inā emi ka mānoanoa o ka sludge ma hope o ka hōʻemi ʻana i ka nui o ka hoʻohui, a laila he pilikia ia o ka nui o ka hoʻohui. Inā ua emi ka nui o ka hoʻohui, ʻaʻole i hoʻokō ʻia ka hopena a ʻaʻole hiki ke kaomi ʻia ka sludge, a laila he pilikia ia o ke koho ʻana i ka huahana.
4. Hoʻohui ʻia ka Polyacrylamide i ka sludge, a kiʻekiʻe loa ka nui o ka wai o ka keke lepo ma hope, he aha kaʻu e hana ai inā ʻaʻole maloʻo ka keke lepo?
I kēia hihia, e nānā mua i nā lako dehydration. Pono ka mīkini kāʻei e nānā inā lawa ʻole ka ʻōniʻoniʻo o ka lole kānana, ka permeability wai o ka lole kānana a inā pono e hoʻololi ʻia ka lole kānana; pono ka mīkini kānana pā a me ka mōlina e nānā inā lawa ka manawa kaomi kānana, Inā kūpono ke kaomi o ke kānana; pono ka centrifuge e nānā inā kūpono ke koho ʻana o ka mea dehydrating. ʻO nā lako dehydration wili a me ka decanter i hoʻopaʻa ʻia e kālele ana i ka nānā ʻana inā kiʻekiʻe loa ke kaumaha molekala o ka polyacrylamide, a ʻo nā huahana me ka viscosity kiʻekiʻe loa ʻaʻole kūpono i ke kaomi ʻana i ka lepo!
Nui nō nā pilikia maʻamau o ka polyacrylamide i ka hoʻoheheʻe ʻana o ka sludge. ʻO nā mea i luna aʻe nā pilikia maʻamau a me nā hoʻonā i hōʻuluʻulu ʻia i loko o kahi helu nui o ka debugging ma ka pūnaewele. Inā he mau nīnau kāu e pili ana i ka kaomi ʻana o ka sludge polyacrylamide cationic a i ʻole ka sedimentation, hiki iā ʻoe ke hoʻouna mai i kahi leka uila iā mākou, e kūkākūkā kākou i ka hoʻohana ʻana o ka polyacrylamide i ka hoʻoheheʻe ʻana o ka sludge!
Ua paʻi hou ʻia mai ka puke kumu ʻo Qingyuan Wan Mukhun.
