Mercury pollution from irrigation with treated sewage water (TSW).
The lack of potable water in arid countries leads to the use of treated sewage water (TSW) for crop growth. Mercury accumulation (up to 500 ng/g) in agricultural soil originating from daily irrigation with TSW was found at two sites fed separately from a hospital sewage plant and an industrial plant. A control site irrigated with potable water ([Hg] <0.01 ng/ml) had much reduced levels in soil ...
متن کاملNitrogen Removal Efficiency of an A2/o Bio-reactor Treating Domestic Sewage Mixed with Landfill Leachate and Fecal Sewage
A set of anaerobic-anoxic-aerobic (A/O) bio-reactor system was used to treat domestic sewage mixed with landfill leachate and fecal sewage in Datansha Sewage Treatment Plant in Guangzhou China. The experiment investigated the optimal mixing proportion of treating landfill leachate, fecal sewage mixed with domestic sewage synchronously and the optimal running conditions for the removal efficienc...
متن کاملNitrogen Transformation within Constructed Wetlands Purifying Secondary Treated Sewage
Most of domestic wastewater is either untreated or only primarily settled by septic tanks in Taiwan. Manure produced by concentrated swine operations is also one of the primary pollution sources of watercourses. Recently, constructed wetlands have received tremendous interests as one of the contemporary alternatives employing to enhance the water quality regarding nitrogen nutrients due to the ...
متن کاملNitrogen Forms, pH and Total Carbon in a Soil Incubated with Treated Sewage Effluent
In this study, an experiment under controlled conditions was carried out to determine the effects of secondarytreated sewage effluent (STSE) application on soil nitrogen concentrations (mineral and total), total carbon and soil pH. The soil and STSE used were collected at Lins, São Paulo State, Brazil. A completely randomized design was used, in completed factorial 4x11 (weekly application rate...
متن کاملTREATED DOMESTIC SEWAGE: KINETICS OF Escherichia coli AND TOTAL COLIFORM INACTIVATION BY OXIDATION WITH HYDROGEN PEROXIDE
Hydrogen peroxide has been used for decades in developed countries as an oxidizing agent in the treatment of water, domestic sewage and industrial effluents. This study evaluated the influence of the concentration of H2O2 and pH on the inactivation of Escherichia coli cells and the disinfection of sewage treated. The results showed that the inactivation rate increased with pH and H2O2. The pres...
