Iko kushandiswa kwesefa yekutsikisa mune inopisa-dip galvanizing bhizinesi muVietnam

Basic information:Bhizinesi rinoita 20000 matani ekupisa-dip galvanizing gore negore, uye kugadzirwa kwemvura yetsvina kunonyanya kugeza tsvina. Mushure mekurapwa, huwandu hwemvura yetsvina inopinda munzvimbo yekuchenesa mvura inosvika 1115 cubic metres pagore. Yakaverengerwa zvichienderana ne300 mazuva ekushanda, huwandu hwemvura yakasvibiswa inogadzirwa inenge 3.7 cubic metres pazuva.

Kurapa maitiro:Mushure mekuunganidza mvura yetsvina, alkaline solution inowedzerwa kune neutralization regulating tank kugadzirisa pH kukosha kusvika 6.5-8. Musanganiswa unoitwa homogenized uye homogenized nepneumatic inokurudzira, uye mamwe ayoni ane ferrous anoiswa oxidized kune iron ions; Mushure mekunyungudika, mvura yakasvibiswa inoyerera ichipinda mutangi yeoxidation yeaeration uye oxidation, kushandura iyo isina kubviswa ion ferrous kuita iron ions uye kubvisa chiitiko che yellowing mumarara; Mushure mekuita sedimentation, tsvina inoyerera yega mutangi remvura inoshandiswa zvakare, uye kukosha kwepH kunogadziriswa kusvika 6-9 nekuwedzera asidhi. Inenge 30% yemvura yakachena inoshandiswa zvakare muchikamu chekusuka, uye yakasara mvura yakachena inosangana nechiyero uye yakabatanidzwa kune pamba yepombi pombi network munzvimbo yefekitari. Dope rinobva mutangi rekuita sedimentation rinobatwa semarara ane ngozi akasimba mushure mekubvisa mvura, uye iyo filtrate inodzoserwa kuhurongwa hwekurapa.

Sefa midziyo yekudhinda: Mechanical dewatering of sludge inoshandisa midziyo yakaita seXMYZ30/630-UBfilter press(yakazara huwandu hwesefa chamber i450L).

Automation matanho:pH yekuzvidzora michina inoiswa munzvimbo dzese dzinosanganisira pH kukosha kwekutonga, zvichiita kuti zvive nyore kushanda uye kuchengetedza dosi yemishonga. Mushure mekushandurwa kwemaitiro kwapera, kubuda kwakananga kwemvura yakasviba kwakaderedzwa, uye kubuda kwezvinosvibisa seCOD neSS kwakaderedzwa. Hunhu hwekuyerera hwakasvika padanho rechitatu chiyero cheComprehensive Wastewater Discharge Standard (GB8978-1996), uye iyo zinc yakazara yakasvika padanho rekutanga.
