I ke kaiapuni hou, ua mālama pono ʻia nā pilikia wai ʻino i hoʻokumu ʻia e ka hoʻomohala ʻoihana ma ka home a ma waho. Ma ke kamaʻilio ʻana i kēia, pono mākou e haʻi i ke kūlana o nā flocculants decolorizing i ka mālama ʻana i ka wai. ʻO ke kumu, pono e hoʻohana nā flocculants decolorizing i hana ʻia e nā ʻoihana he nui. E hoʻolauna ʻo Yixing Cleanwater iā ʻoe i ka ʻike pili a me nā noi ma nā ʻano like ʻole.
Hoʻohana nui ʻia nā flocculants decolorizing polymer like ʻole ma ke kahua o ka wai ʻoihana a me ka mālama ʻana i ka wai ʻino ma nā ʻāina ʻē, ʻo ia hoʻi ka polyacrylamide (PAM) ke ʻano nui o ka flocculant decolorizing. Ke hoʻohālikelike ʻia me nā flocculants paʻakai inorganic kuʻuna, ʻo PAM, ma ke ʻano he ʻano hou o ka mea mālama wai, he nui nā pono: maʻalahi a maʻalahi hoʻi e hoʻohana, ʻoi aku ka nui o ka hopena flocculation ma mua o nā flocculants decolorizing paʻakai inorganic kuʻuna; wikiwiki ka flocculation a me ka sedimentation, kiʻekiʻe ka pono o ka dewatering sludge; hopena lapaʻau kūikawā ma kekahi mau wai ʻino; pono nā lako maʻalahi, kapuaʻi liʻiliʻi; haʻahaʻa ke kumukūʻai lapaʻau; hiki ke hana hou ʻia a hoʻohana hou ʻia ka wai ʻino, a pēlā aku.
Hoʻohana ʻia oʻO ka flocculant hoʻohemo kala PAM ma nā kahua noi like ʻole:
1. Hoʻohana ʻia ma ka ʻoihana hana pepa
ʻO ka hoʻohana ʻana i ka PAM kaumaha molekala kiʻekiʻe ma ke ʻano he flocculant decolorizing hiki ke hoʻonui i ka nui o ka ua o nā pigments a me nā mea ʻē aʻe i loko o ka wai keʻokeʻo a hōʻemi i ko lākou nalowale. ʻO ka hoʻohui ʻana i ka 0.25 ~ 0.5% PAM i ka pulp hiki ke hoʻonui i ka nui o ka sedimentation o ka pulp ma 40 ~ 80 mau manawa, hoʻemi i ka nui o ka paʻa i loko o ka wai keʻokeʻo ma kahi o 66%, hoʻonui i ka nui o ka lehu o ka pepa, hoʻonui i ka nui o ka paʻa ʻana o nā pigments e like me ka lepo keʻokeʻo ma 8 ~ 18%, a mālama i 20kg o ka pulp no kēlā me kēia tona o ka pepa. Eia kekahi, ma hope o ka hoʻohana ʻana i ka PAM, ua emi nui ka turbidity o ka wai keʻokeʻo, e hōʻemi ana i ka haumia o ke kaiapuni. No ka laʻana, ʻo nā mea paʻa i hoʻokuʻu ʻia o ka wai hoʻoheheʻe pulp keʻokeʻo waiū me ka pH = 6.8 he 3000ppm. Ma hope o ka mālama ʻia ʻana me ka PAM me ke kekelē hydrolysis o 5 ~ 10%, ke kaumaha molekala o 5.5 ~ 10 miliona, a me 500ppm o ka alumini sulfate, hiki ke hoʻololi ʻia ka wai keʻokeʻo i wai ʻole a moakāka, a hoʻemi ʻia nā mea paʻa i hoʻokuʻu ʻia i lalo o 50ppm.
2. Ka hoʻohana ʻana i nā flocculants decolorizing i ka mālama ʻana i ka wai
①Anti-scaling a me ka descaling
I ka mālama ʻana i ka wai ʻoihana a me ka wai hoʻoheheʻe ʻia, pono e hoʻomālamalama mua ʻia ka wai maka. Hoʻohana pinepine ʻia nā flocculants decolorizing PAM a me nā coagulants inorganic i ka hui pū ʻana, hiki ke hōʻemi nui i ka hoʻohana ʻana i nā coagulants inorganic, pale i ka paʻa ʻana o nā lako a me ka pala ma muli o ka hoʻohana nui ʻana i nā coagulants inorganic, a pale i ka hoʻokumu ʻia ʻana o ke unahi. Hoʻohana ʻia he 37.5 mau ʻāpana o PAM me ke kaumaha molekala ma lalo o 1 miliona a me 50 mau ʻāpana o ka sodium tripolyphosphate e hana i kahi mea hoʻopaʻa unahi, hiki ke pale i ke unahi o nā mea hoʻololi wela unahi nui.
②Ka mālama ʻana i ka wai ʻino ʻoihana
3. Ka hoʻohana ʻana o nā flocculants decolorizing i ka mālama ʻana i ka wai hoʻoneoneo ma ka ʻoihana kō
ʻO ka wai kō i unuhi ʻia mai ka mīkini paʻi e nā hale hana kō he mea ʻūlū pinepine ia a he paʻakikī hoʻi kona ʻano. I mea e loaʻa ai ka wai kō maʻemaʻe, pono e hoʻohui ʻia nā mea hoʻomālamalama kemika. I ka wā ma mua, ua hoʻohana pinepine ʻia nā flocculants decolorizing inorganic, akā me ka hoʻomohala ʻana o ka ʻoihana kō, ʻaʻole hiki i nā flocculants decolorizing inorganic ke hoʻokō hou i nā pono hana. I nā makahiki i hala iho nei, hiki i ka hoʻohana ʻana o PAM i ka ʻoihana kō ke hoʻonui i ka nui o ka sedimentation ma 20 mau manawa.
I ka hōʻuluʻulu manaʻo, ke koho mākou i ka polyacrylamide PAM decolorization flocculant e like me ke kūlana maoli, pono mākou e koho iā ia e like me nā hiʻohiʻona noi like ʻole a me nā kūlana. No laila, he mea nui loa ke koho ʻana o ka polyacrylamide.
Inā makemake ʻoe i kā mākou huahana, e ʻoluʻolu e kelepona mai iā mākoukāhea iā mā˚ou!
