Metala Kaumaha Wehe Agent CW-15
wehewehe
Heavy Metal Wehe AgenaCW-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 ʻanaanakaumaha noʻonoʻo mai ka wai.Ma hope o ka lapaʻau ʻana, ka Precipitationhiki ole ke hoopaudma ka ua, Aiaʻaʻole't kekahipilikia hoʻohaumia lua.
Nā Manaʻo Kūʻai
Kahua noi
Wehe i ka metala koʻikoʻi 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, mea kanu Petrochemical, hale hana kaʻa a me pela aku.
Pōmaikaʻi
1. Palekana kiʻekiʻe.ʻAʻohe mea ʻawaʻawa, ʻaʻohe ala ʻino, ʻaʻohe mea ʻawaʻawa i hana ʻia ma hope o ka mālama ʻana.
2. ʻO ka hopena wehe maikaʻi.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.Aia nā ion metala kaumaha i ke ʻano o ka paʻakai paʻakikī (EDTA, tetramine etc.) ʻaʻole hiki ke hoʻoneʻe loa 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.
Nā kikoʻī
Ka Papa Hana
Wai ʻino → Hoʻololi i ka PH i 7-10 → Hoʻohui i ka CW 15 me ka hoʻoulu ʻana no 30 mau minuke → Hoʻohui i ka flocculant organik me ka hoʻoulu ʻana → hoʻoulu mālie no 15 mins → Sedimentation → kānana → Wai mālama ʻia
Hōʻike helu o CW 15 no 10PPM ion metala kaumaha
Pūʻolo a me Storge
Pūʻolo
Hoʻopili ʻia ka wai i loko o ka pahu polypropylene, 25kg a i ʻole 1000kg pahu
paʻa paʻa i loko o ka ʻeke pepa-plastic composite, 25Kg/ʻeke.
Loaʻa ka hoʻopili paʻa.
Storge
E mālama i loko o ka hale, e maloʻo, e hoʻoheheʻe ʻia, e pale i ka lā pololei, e pale i ka hoʻopili ʻana me ka waikawa a me ka oxidizer.
ʻElua mau makahiki o ka mālama ʻana, ma hope o ʻelua mau makahiki, hiki ke hoʻohana wale ʻia ma hope o ka nānā hou ʻana a me ke kūpono.
ʻO nā kemika pili ʻole.
Kaʻahele
I ka lawe ʻana, pono e mālama ʻia e like me nā kemika maʻamau, e pale i ka haki ʻana o ka pūʻolo a pale i ka lā a me ka ua.
