| Abstract: | The results showed that the technique of pack absorption tower for purification of the waste gas form printed circuit board plant were affective and economic.The contaminant removal efficiency exceeded 90% after being treated by one grade absorption tower with the absorbent of NaOH solution,the concertration of contaminant in exhaust did not exceeded the maximum limit of free discharge.Purified by two grade pack absorption tower,the second grade tower with absorbent of mixed solution of acetic acid and surface active agent,total removal efficiency of the contaminant of benzene,methylbenzene,dimethyl benzene,formaldehyde and lead exceeded 99.7%.The operation cost was 55×10 -4 RMB/m 3/h. |
