Notes
This work was carried out to reveal the concentration of heavy metals in the sludge produced biological domestic sewage treatment plant, referring to assess agricultural use of the sludge. The mean heavy metal concentration in the domestic sewage sludge produced from bio-film process were 22.8 mg/ss-kg for Cr, 200 mg/ss-kg for Cu, 1,030 mg/ss-kg for Zn, 8,970 mg/ss-kg for Fe, 260 mg/ss-kg for Mn and 60.0 mg/ss-kg for Pb, respectively. It is suggested that these values are nearly minimum concentration of the heavy metals in the sludge produced from biological treatment.
