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 polymer organik ʻōmaʻomaʻo a ʻaʻohe mea ʻawaʻawa, hiki ke loaʻa ka hopena hoʻohemo maikaʻi i nā metala kaumaha. ʻO ka maʻamau, mālama ʻia me nā mea wehe metala kaumaha a me nā pahele metala kaumaha. He mea paʻakikī ke hana hou ʻana a me ka hana ʻana o ka slag, a aia ka pilikia o ka pollution lua; a ʻo ka CW-15 o kā mākou hui he ʻōmaʻomaʻo metala kaumaha, a ʻaʻohe pilikia o ka pollution lua ma hope o ka mālama ʻana i nā metala kaumaha.
Hiki i ka Heavy Metal Ion Catcher Agent ke wehe i ka metala kaumaha mai ka wai ʻino e like me: desulfurization wai ʻino mai ka hale mana ahi ahi (ka hana desulfurization pulu) wai ʻino mai ka hale paʻi papa kaapuni paʻi (Plated copper), hale hana electroplating (Zinc), holoi kiʻi kiʻi, Petrochemical Mea kanu, hale hana kaa a pela 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 hapa nui o nā iona 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.
