Ibyuma biremereye ni itsinda ryibintu birimo ibyuma na metalloide nka arsenic, kadmium, chromium, cobalt, umuringa, icyuma, gurş, manganese, mercure, nikel, amabati na zinc.Iyoni z'ibyuma zizwiho kwanduza ubutaka, ikirere hamwe na sisitemu y'amazi kandi ni uburozi kabone niyo byaba ari bike cyane.
Hariho amasoko abiri yingenzi yibyuma biremereye mumazi, amasoko karemano nisoko ya antropogene.Inkomoko karemano zirimo ibikorwa byibirunga, isuri yubutaka, ibikorwa byibinyabuzima, hamwe nikirere cyamabuye namabuye y'agaciro, mugihe isoko ya antropogeneque irimo imyanda, gutwika lisansi, gutemba mumihanda, imyanda, ibikorwa byubuhinzi, ubucukuzi bwamabuye y'agaciro, hamwe n’inganda zangiza amarangi nko gusiga amarangi.Ibyuma biremereye byashyizwe mu rwego rw’uburozi na kanseri, birashobora kwirundanyiriza mu ngingo no gutera indwara n’imivurungano.
Kurandura ibyuma biremereye ion mumazi mabi nibyingenzi mugusukura ibidukikije nubuzima bwabantu.Hariho uburyo butandukanye bwatangajwe bugamije kuvanaho ioni ziremereye ziva mumazi atandukanye.Ubu buryo bushobora gushyirwa mubikorwa bya adsorption, membrane, imiti, electro, hamwe nubuvuzi bushingiye kumafoto.
Isosiyete yacu irashobora gutangaGukuraho Ibyuma Bikomeye, Gukuraho Ibyuma Bikomeye Umukozi CW-15 ntabwo ari uburozi kandi bwangiza ibidukikije bifata ibyuma biremereye.Iyi miti irashobora gukora uruganda ruhamye hamwe na ion nyinshi zicyuma kandi zingana mumazi yimyanda, nka: Fe2 +, Ni2 +, Pb2 +, Cu2 +, Ag +, Zn2 +, Cd2 +, Hg2 +, Ti + na Cr3 +, hanyuma ukagera kumugambi wo gukuraho ubwenge bukomeye bwo mumutwe kuva mu mazi.Nyuma yo kuvurwa, Imvura ntishobora gushonga imvura, Nta kibazo cya kabiri cyanduye.
Ibyiza ni ibi bikurikira:
1. Umutekano muke.Ntabwo ari uburozi, nta mpumuro mbi, nta bikoresho byuburozi byakozwe nyuma yo kuvurwa.
2. Ingaruka nziza yo gukuraho.Irashobora gukoreshwa muburyo bugari bwa pH, irashobora gukoreshwa mumazi ya aside cyangwa alkaline.Iyo ion ibyuma bibana, birashobora gukurwaho icyarimwe.Iyo ibyuma biremereye ion biri muburyo bwumunyu utoroshye (EDTA, tetramine nibindi) bidashobora gukurwaho burundu nuburyo bwa hydroxide yimvura, iki gicuruzwa gishobora no kugikuraho.Iyo itoboye ibyuma biremereye, ntabwo bizabangamirwa byoroshye numunyu ubana mumazi yimyanda.
3. Ingaruka nziza ya flocculation.Gutandukana gukomeye-gutemba byoroshye.
4.Ubutaka bwibyuma biremereye birahagaze, ndetse no kuri 200-250 ℃ cyangwa acide aside.
5. Uburyo bworoshye bwo gutunganya, kuvoma byoroshye.
Niba ushishikajwe nibicuruzwa byacu, murakaza neza.Turacyagukorera mugihe cy'Ibirori.
