Heavy metal iboka rekutsvaga zvinhu zvinosanganisira simbi uye metalloids zvakaita se arsenic, cadmium, chromium, cobalt, mhangura, iron, lead, manganese, mercury, nickel, tini uye zinc. Metal ions inozivikanwa kusvibisa ivhu, mhepo uye mvura masisitimu uye ine muchetura kunyangwe pakadzika kwazvo.
Kune maviri makuru masosi emasimbi anorema mumvura, masosi masosi uye anthropogenic masosi. Zvisikwa zviwanikwa zvinosanganisira kuputika kwemakomo, kukukurwa kwevhu, biological chiitiko, uye mamiriro ekunze ematombo nezvicherwa, nepo anthropogenic masosi anosanganisira marara, kupisa kwemafuta, kubuda mumigwagwa, tsvina, mabasa ekurima, migodhi, uye zvinosvibisa maindasitiri zvakaita sedhayi dzemachira. Heavy metals inoratidzirwa sehupfu uye carcinogenic, inokwanisa kuunganidza mumatishu uye kukonzera chirwere uye kusagadzikana.
Kubviswa kweheavy metal ions kubva mumvura yetsvina kwakakosha pakuchenesa nharaunda uye hutano hwevanhu. Pane nzira dzakasiyana dzakataurwa dzakatsaurirwa kubviswa kweheavy metal ions kubva kune dzakasiyana siyana dzetsvina. Idzi nzira dzinogona kuiswa mu adsorption, membrane, makemikari, electro, uye photocatalytic based kurapwa.
Kambani yedu inogona kupaHeavy Metal Bvisa Agent, Heavy Metal Bvisa Agent CW-15 haisi-chepfu uye inoshamwaridzana-inoshamwaridzana heavy metal catcher. Kemikemikari iyi inogona kuumba musanganiswa wakagadzikana une maion simbi akawanda emonovalent uye divalent mumvura ine tsvina, se:Fe2+,Ni2+,Pb2+,Cu2+,Ag+,Zn2+,Cd2+,Hg2+,Ti+neCr3+, wosvika pachinangwa chekubvisa pfungwa dzinorema. kubva mumvura. Mushure mekurapwa, iyo Precipitation haigone kunyungudika nemvura, Hapana dambudziko rekusvibisa rechipiri.
Zvakanakira ndezvizvi:
1. Kuchengetedzwa kwepamusoro. Kwete-chepfu, hapana kunhuwa kwakashata, hapana zvinhu zvine muchetura zvinogadzirwa mushure mekurapwa.
2. Zvakanaka kubvisa maitiro. Inogona kushandiswa muhupamhi pH renji, inogona kushandiswa muasidhi kana alkaline wastewater. Kana ioni dzesimbi dzichigara pamwe chete, dzinogona kubviswa panguva imwe chete. Kana iyo heavy metal ions iri muchimiro chemunyu wakaoma (EDTA, tetramine etc) usingagoni kubviswa zvachose ne hydroxide precipitate method, chigadzirwa ichi chinogona kuchibvisa zvakare. Painobvisa simbi inorema, haizovharidzirwe nyore nemunyu wakagara mumvura ine tsvina.
3. Yakanaka flocculation effect. Kuparadzana kwakasimba-mumvura zviri nyore.
4.Heavy metal sediments yakagadzikana, kunyange pa 200-250 ℃ kana dilute acid.
5. Nyore kugadzirisa nzira, nyore sludge dewatering.
Kana iwe uchifarira zvigadzirwa zvedu, welcome to consult. Tichiri kukushandirai panguva yeMutambo weChirimo.
