ʻO ka mea hoʻoneʻe metala kaumaha ka huaʻōlelo maʻamau no nā mea hana e hoʻoneʻe pono i nā metala kaumaha a me ka arsenic i loko o ka wai ʻino i ka mālama ʻana. ʻO ka mea hoʻoneʻe metala kaumaha he mea kemika.
Ma ka hoʻohui ʻana i kahi mea hoʻoneʻe metala koʻikoʻi, hana kemika nā metala kaumaha a me ka arsenic i loko o ka wai ʻino e hana i nā mea hiki ʻole ke hoʻoheheʻe i ka wai, hiki ke hoʻokaʻawale ʻia mai ka wai a hoʻomaʻemaʻe i ka wai ʻino. He liʻiliʻi ka nui o ka sludge, a he kiʻekiʻe ka neʻe ʻana o nā metala kaumaha, hiki ke hana hou ʻia a hoʻoheheʻe ʻia. Nā mahinaʻai: ka mining, ka hoʻoheheʻe metala a me ka hana ʻana, ka hana kemika, electroplating, electronics, paʻi a me ka hoʻoluʻu a me nā ʻoihana ʻē aʻe.
Aia i kēia manawa ʻelua ʻano lāʻau lapaʻau no ka mālama ʻana i ka wai ʻino metala kaumaha e kū nei ma ka mākeke, ʻo kekahi he mea hoʻoheheʻe metala kaumaha, a ʻo kekahi he mea wehe metala kaumaha; ʻO ka mea hoʻoneʻe metala kaumaha a me ka scavenger metala kaumaha, he ʻano waiwai like nō ia, ʻo Xanthate a me dithiocarbamate derivatives me nā mea ʻawaʻawa haʻahaʻa.
ʻO ke kaiapunimetala kaumaha CW-15i hoʻomohala ʻia e kā mākou hui he polimer organik ʻōmaʻomaʻo a ʻaʻohe mea ʻawaʻawa, hiki ke loaʻa i kahi hopena maikaʻi loa i nā metala kaumaha. ʻO ka maʻamau, mālama ʻia me nā mea wehe metala kaumaha a me nā pahele metala kaumaha. He paʻakikī ke hana hou ʻana a me ka hana ʻana i ka slag, a aia ka pilikia o ka lua; a ʻo ka CW-15 o kā mākou hui he ʻōmaʻomaʻo metala kaumaha, ʻaʻohe pilikia o ka pollution lua ma hope o ka mālama ʻana i nā metala kaumaha.
Hiki iā Heavy Metal Ion Catcher Agent ke wehe i nā metala kaumaha mai ka wai ʻino e like me: desulfurization wastewater from Coal-fired power plant (wet desulfurization process) wastewater from Printed circuit board plating plant (Plated copper), Electroplating factory (Zinc),Photographic Rinse, Petrochemical Plant, Automobile production plant a pēlā aku.Metala Kaumaha Wehe Agent CW-15he mea ʻawaʻawa ʻole a pili i ke kaiapuni. Hiki i kēia kemika ke hana i pūhui paʻa me ka nui o nā ion metala monovalent a me divalent i loko o ka wai ʻino, 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 noʻonoʻo kaumaha mai ka wai. Ma hope o ka mālama ʻana, ʻaʻole hiki ke hoʻoheheʻe ʻia ka ua e ka ua, ʻaʻohe pilikia lua.
Eia nā pono o ia mea:
1. Palekana kiʻekiʻe. ʻAʻohe mea ʻawaʻawa, ʻaʻohe ala ʻino, ʻaʻohe mea ʻawaʻawa i hana ʻia ma hope o ka mālama ʻana.
2. Hoʻopau maikaʻi ka hopena. Hiki ke hoʻohana ʻia i ka laulā pH ākea, hiki ke hoʻohana ʻia i ka wai ʻawaʻawa a i ʻole alkaline wai. Ke noho like nā ion metala, hiki ke wehe ʻia i ka manawa like. Ke loaʻa nā ion metala kaumaha i ke ʻano o ka paʻakai paʻakikī (EDTA, tetramine a me nā mea ʻē aʻe) ʻaʻole hiki ke hoʻoneʻe ʻia e ka hydroxide precipitate method, hiki i kēia huahana ke wehe pū. Ke hoʻomoe ʻo ia i ka metala kaumaha, ʻaʻole hiki ke keakea ʻia e nā paʻakai i hui pū ʻia me ka wai ʻino.
3. ʻO ka hopena flocculation maikaʻi. Māmā ka hoʻokaʻawale ʻana i ka wai paʻa.
4. He paʻa nā sediments metala kaumaha, ʻoiai ma 200-250 ℃ a i ʻole dilute acid.
5. ʻO ke ʻano hana maʻalahi, maʻalahi ka hoʻoheheʻe ʻana i ka lepo.
"ʻO kaʻoiaʻiʻo, ka hana hou, ka ikaika, a me ka maikaʻi" ʻo ia ka manaʻo hoʻomau o kā mākou paʻa no kēlā manawa lōʻihi e loaʻa me kekahi me nā mea kūʻai aku no ka launa like ʻana a me ka uku like ʻole no ke kūlana kiʻekiʻe.Hoolako Mea Hana Pake, Hoʻokipa maikaʻi mākou i nā mea kūʻai aku a me nā ʻāina ʻē e hoʻouna i ka nīnau iā mākou, ua loaʻa iā mākou he 24hours hana hana! I kēlā me kēia manawa ma nā wahi āpau a mākou i noho ai ma ʻaneʻi ʻo kāu hoa.
