If it is discharged into water, it will produce heavily polluted. At present, the iron yellow wastewater is collected and treated. The specific process is: the iron yellow wastewater is pumped into the aeration adjustment tank, and then pumped into the first-level neutralization reaction tank, the second-level neutralization reaction tank, and the third-level neutralization reaction. pool, and then sent to the inclined tube sedimentation tank, in which the sludge is sent to the sludge thickening tank, after sludge dehydration treatment; the treated water enters the intermediate pool; since the above iron yellow wastewater treatment process uses air agitation, it is very difficult It is difficult to completely precipitate the iron ions in the sewage, so the actual wastewater treatment effect is not good. After the above wastewater treatment, it cannot be reused for production.
