ʻO ka mea hoʻohemo metala kaumaha ka huaʻōlelo maʻamau no nā mea hana e wehe pono i nā metala kaumaha a me ka arsenic i loko o ka wai hoʻoneoneo i ka mālama ʻana i ka wai hoʻoneoneo. He mea kemika ka mea hoʻohemo metala kaumaha.
Ma ka hoʻohui ʻana i kahi mea hoʻohemo metala kaumaha, hana kemika nā metala kaumaha a me ka arsenic i loko o ka wai hoʻoneoneo e hana i nā mea hoʻoheheʻe wai ʻole, hiki ke hoʻokaʻawale ʻia mai ka wai a hoʻomālamalama i ka wai hoʻoneoneo. He liʻiliʻi ka nui o ka sludge, a kiʻekiʻe ka nui o nā metala kaumaha, hiki ke hana hou ʻia a hoʻoheheʻe ʻia. Nā kahua: eli ʻana, hoʻoheheʻe a me ka hana ʻana i ka metala, hana kemika, electroplating, electronics, paʻi a me ka hoʻoluʻu ʻana a me nā ʻoihana ʻē aʻe.
I kēia manawa, aia ʻelua ʻano lāʻau lapaʻau no ka mālama ʻana i ka wai hoʻokahe metala kaumaha i loaʻa mua ma ka mākeke, ʻo kekahi he mea hoʻohemo metala kaumaha, a ʻo kekahi he mea wehe metala kaumaha; ʻo ka mea wehe metala kaumaha a me ka mea hoʻohemo metala kaumaha he ʻano like ia o ka mea, ʻo nā mea i loaʻa mai ka Xanthate a me ka dithiocarbamate me ka haʻahaʻa o ka ʻawahia.
ʻO ke aloha kaiapunimea wehe metala kaumaha CW-15i hoʻomohala ʻia e kā mākou hui he polymer organik ʻōmaʻomaʻo a ʻaʻohe ʻawaʻawa, hiki ke loaʻa kahi hopena wehe maikaʻi i nā metala kaumaha. Ma keʻano laulā, mālama ʻia me nā mea wehe metala kaumaha a me nā pahele metala kaumaha. He paʻakikī ke hana hou a me ka hana ʻana i ka slag, a aia kahi pilikia o ka haumia lua; a ʻo ka CW-15 o kā mākou hui he mea hoʻoheheʻe metala kaumaha ʻōmaʻomaʻo, a ʻaʻohe pilikia o ka haumia lua ma hope o ka mālama ʻana i ka metala kaumaha.
Hiki i ka Heavy Metal Ion Catcher Agent ke wehe i ka metala kaumaha mai ka wai ʻōpala e like me: ka wai hoʻoheheʻe desulfurization mai ka hale hana mana lanahu (kaʻina hana desulfurization pulu) ka wai hoʻoheheʻe mai ka hale hana plating papa kaapuni paʻi (keleawe paʻa), hale hana Electroplating (Zinc), holoi kiʻi, hale hana Petrochemical, hale hana hana kaʻa a pēlā aku.Mea Hoʻohemo Metala Kaumaha CW-15he mea hopu metala kaumaha ʻaʻohe ʻawahia a aloha i ke kaiapuni. Hiki i kēia kemika ke hana i kahi hui paʻa me ka hapa nui o nā iona metala monovalent a me divalent i loko o ka wai ʻōpala, e like me: Fe2+, Ni2+, Pb2+, Cu2+, Ag+, Zn2+, Cd2+, Hg2+, Ti+ a me Cr3+, a laila hiki i ke kumu o ka wehe ʻana i ka naʻau kaumaha mai ka wai. Ma hope o ka mālama ʻana, ʻaʻole hiki ke hoʻoheheʻe ʻia ka Precipitation e ka ua, ʻAʻohe pilikia haumia lua.
Eia nā pono o ia mau mea:
1. Palekana kiʻekiʻe. ʻAʻohe mea ʻawahia, ʻaʻohe ʻala ʻino, ʻaʻohe mea ʻawahia i hana ʻia ma hope o ka mālama ʻana.
2. Ka hopena wehe maikaʻi. Hiki ke hoʻohana ʻia ma ka pae pH ākea, hiki ke hoʻohana ʻia i loko o ka wai hoʻoneoneo waikawa a alkaline paha. Ke hui pū nā ion metala, hiki ke wehe ʻia i ka manawa like. Ke ʻano o ka paʻakai paʻakikī nā ion metala kaumaha (EDTA, tetramine etc) ʻaʻole hiki ke wehe loa ʻia e ke ʻano hydroxide precipitate, hiki i kēia huahana ke wehe pū. Ke hoʻomoe ʻia ka metala kaumaha, ʻaʻole ia e ālai maʻalahi ʻia e nā paʻakai i hui pū ʻia i loko o ka wai hoʻoneoneo.
3. Ka hopena flocculation maikaʻi. Hoʻokaʻawale maʻalahi i ka wai-paʻa.
4. Paʻa nā metala kaumaha, ʻoiai ma 200-250 ℃ a i ʻole ka waikawa hoʻoheheʻe ʻia.
5. ʻAno hana maʻalahi, hoʻomaʻemaʻe maʻalahi i ka sludge.
ʻO "ʻoiaʻiʻo, hana hou, kūpaʻa, a me ka pono" ka manaʻo paʻa o kā mākou ʻoihana no ka wā lōʻihi e kūʻai pū me nā mea kūʻai aku no ka pānaʻi like ʻana a me ka uku like no ke kūlana kiʻekiʻe.Hoʻolako Mea Hana Kina, Hoʻokipa maikaʻi mākou i nā mea kūʻai aku kūloko a me nā ʻāina ʻē e hoʻouna mai i ka nīnau iā mākou, loaʻa iā mākou he 24 mau hola hana! I kēlā me kēia manawa ma nā wahi āpau, aia nō mākou ma ʻaneʻi e lilo i hoa hana nou.
