Tšebeliso ea mochine oa ho filthara khoebong ea ho letsa ka galvanizing e chesang Vietnam

Tlhahisoleseding ea motheo:Khamphani e sebetsana le lithane tse 20000 tsa galvanizing e chesang selemo le selemo, 'me metsi a litšila a hlahisoang haholo-holo a hlatsoa metsi a litšila. Kamora ho hloekisoa, bongata ba metsi a litšila a kenang seteisheneng sa phekolo ea metsi a litšila ke li-cubic metres tse 1115 ka selemo. Ha e baloa ho latela matsatsi a 300 a mosebetsi, bongata ba metsi a litšila a hlahisoang ke li-cubic metres tse ka bang 3.7 ka letsatsi.

Mokhoa oa kalafo:Kamora ho bokella metsi a litšila, tharollo ea alkaline e eketsoa ka tankeng e laolang ho se sebetse hantle ho fetola boleng ba pH ho 6.5-8. Motsoako o etsoa hore o be o le mong 'me o be o le mong ka ho hlohlelletsa ka moea, 'me li-ion tse ling tsa ferrous li oxidized ho ba li-ion tsa tšepe; Kamora ho sedimentation, metsi a litšila a phallela ka tankeng ea oxidation bakeng sa moea le oxidation, a fetola li-ion tsa ferrous tse sa tlosoang hore e be li-ion tsa tšepe le ho felisa ketsahalo ea ho ba mosehla ka har'a sedimentation; Kamora ho sedimentation, sediment e phalla ka bo eona ka tankeng ea metsi e sebelisoang hape, 'me boleng ba pH bo fetoloa ho 6-9 ka ho eketsa asiti. Hoo e ka bang 30% ea metsi a hloekileng a sebelisoa hape karolong ea ho hlatsoa, ​​​​'me metsi a hloekileng a setseng a fihlela maemo a tloaelehileng 'me a hokahantsoe le marang-rang a liphaephe tsa likhoerekhoere tsa lapeng sebakeng sa fektheri. Seretse se tsoang tankeng ea sedimentation se tšoaroa e le litšila tse kotsi tse tiileng kamora ho tlosoa metsi, 'me sefiltara se khutlisetsoa tsamaisong ea kalafo.

Lisebelisoa tsa ho filthara: Ho tlosa metsi ka mechine seretseng ho sebelisa lisebelisoa tse kang XMYZ30/630-UBmochine oa ho sefa(bokgoni bohle ba kamore ya filthara ke 450L).

Litekanyo tsa othomathiki:Lisebelisoa tsa ho itlhokomela tsa pH li kentsoe libakeng tsohle tse kenyeletsang taolo ea boleng ba pH, e leng se etsang hore ho be bonolo ho li sebelisa le ho boloka tekanyo ea meriana. Kamora hore phetoho ea ts'ebetso e phetheloe, ho ntšoa ha metsi a litšila ka kotloloho ho ile ha fokotseha, 'me ho ntšoa ha litšila tse kang COD le SS ho ile ha fokotseha. Boleng ba litšila bo fihlile boemong ba boraro ba Tekanyetso e Felletseng ea ho Ntšoa ha Metsi a Litšila (GB8978-1996), 'me zinki eohle e fihlile boemong ba pele.
