胎圈钢丝生产中“三废”的处理

采用废水处理系统处理胎圈钢丝生产中的废水废渣,使废水中ρ(Cu2+)由200 mg/L降为0.5 mg/L,达到GB 8978—1996《污水综合排放标准》的一级排放标准。采用酸雾净化塔处理生产中的废气,使废气中HC l的质量浓度由400 mg/m3降为18 mg/m3,净化效率达到96%,H2SO4质量浓度由200 mg/m3降到16 mg/m3,净化效率为92%,达到了GB 16297—1996《大气污染综合排放标准》的规定。

Treatment of "Three Wastes" in Production of Tyre Steel Wire

Adopting waste water treatmemt system to treat waste water and residue in production of tyre steel wire makes Cu2+ mass concentration in waste water reduce from 200 mg/L to 0.5 mg/L,which reaches grade A letting of GB8978-1996 Sewage Synthesis Letting Standard.Adopting acid fog purifying tower to treat waste gas of production makes the HCl density in waste gas reduces from 400 mg/m3 to 18 mg/m3,its purifying rate reaches 95%;H2SO4 density reduces from 200 mg/m3 to 16 mg/m3,its purifying rate reaches 92%.These reaches the stipulation in GB 16297—1996 Atmosphere Pollution Synthesis Letting Standard.
