Total concentrations and different fractions of heavy metals in sewage sludge from Guangzhou, China
Dewatered municipal sludge samples were collected from five municipal wastewater treatment plants (WWTPs) and one industrial WWTP in Guangzhou, China. A number of agricultural parameters and total metal concentrations in the sludge were determined. Metal speciation was also studied. The results showed that sewage sludge had high organic carbon, and was rich in such nutrients as N and P. The con...
متن کاملMobility of heavy metals in soils amended with sewage sludge
Morera, M. T., Echeverría, J. C. and Garrido, J. J. 2001. Mobility of heavy metals in soils amended with sewage sludge. Can. J. Soil Sci. 81: 405–414. Sewage sludges added to arable land can improve soil fertility and physical properties. However, the concentrations of heavy metals commonly found in sludges limits their application to soil. The purpose of this paper is to evaluate the mobility ...
متن کاملBioavailability of heavy metals in soils amended with sewage sludge
Morera, M. T., Echeverría J. and Garrido, J. 2002. Bioavailability of heavy metals in soils amended with sewage sludge. Can. J. Soil Sci. 82: 433–438. The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and Zn applied to soils in urban...
متن کاملLeachability of Heavy Metals from Lightweight Aggregates Made with Sewage Sludge and Municipal Solid Waste Incineration Fly Ash
Lightweight aggregate (LWA) production with sewage sludge and municipal solid waste incineration (MSWI) fly ash is an effective approach for waste disposal. This study investigated the stability of heavy metals in LWA made from sewage sludge and MSWI fly ash. Leaching tests were conducted to find out the effects of MSWI fly ash/sewage sludge (MSWI FA/SS) ratio, sintering temperature and sinteri...
متن کاملRemoval of Heavy Metals from Urban Sewage Sludge Using Acidophilic Thiobacillus ferrooxidans
Background & objectives: The presence of heavy metals in urban sewage sludge limits its use as a soil modifier. The purpose of this study was to remove heavy metals (Cu, Zn, Cd and Pb) from urban sewage sludge using Acidophilic Thiobacillus ferrooxidans bacteria. Methods: In this experimental study, the sludge samples were collected from Shiraz wastewater treatment plant. Bioleaching tests were...
