titleOfInvention | Heavy metal sewage treatment process |
abstract | The invention belongs to the technical field of sewage treatment, and particularly relates to a heavy metal sewage treatment process. The process relates to the treatment of soluble heavy metal and suspendable heavy metal, the removal rate of the heavy metal is more than 95 percent, and the process reaches the discharge standard specified by the state; the method has no influence on a biochemical treatment system, and does not influence the functions and effects of degrading COD, nitrifying ammonia nitrogen and denitrifying nitrogen; meanwhile, the water outlet ensures that the adding of the medicament avoids the possibility of adding excessive heavy metal sewage treatment medicament and discharging the heavy metal sewage treatment medicament into the environment along with the water outlet, thereby generating unknown influence on the environment. |
