The growing demand for fresh water is partially satisfied by desalination plants that increasingly use membrane technologies and among them advanced oxidation processes emerging ozone to produce purified water. In this research, the water purification technology using advanced oxidation processes emerging ozone to be able to eliminate the content of humus acids and organic compounds is developed....
Around 2300 tanneries in India produces 6000 tones of solid waste per annum, that includes 15000 tones of chromed leather shavings waste. This contain Chromium. Cr (VI) compounds used in leather processing which are highly water soluble, toxic, carcinogenic and a potential ground water contaminant. The MoEF have classified the chromium bearing solid wastes in the hazardous waste category that necessitates...
The efficiency of electrokinetic remediation of Cu contaminated groundwater was researched by means of experiments for the complicated remediation of groundwater contaminated by typical heavy metal in this paper, and migration and variation characteristics of Cu was analyzed too. The experimental results indicated that the pH value varied obviously during the electrokinetic remediation because of...
The efficiency of electrokinetic remediation of zinc contaminated soils and the influence of complex EDTA were researched by means of experiment for the complicated remediation of soil contaminated by typical heavy metal in this paper, and migration and variation characteristics of zinc were analyzed too. The experimental results indicated that the heavy metal pollutant could be enriched and removed...
Arsenic accumulation by hyperaccumulator, Pteris vittata, when exposed to arsenite in hydroponics is comparable to that when exposed to arsenate while arsenite uptake is considerably slower than arsenate uptake. Arsenite species around root and that in the incubating solution were analyzed to investigate arsenite oxidation in hydroponics. XANES analysis of the fern roots showed that arsenate predominated...
The effect of preoxidation Yellow River with light polluted water by composite potassium permanganate process are studied in the text. The best adding quantity of composite potassium permanganate is 1.5-3.0 mg/l, PAC as the flocculant, the best adding quantity is 60 mg/l. Under these conditions, pretreat Yellow River with mic-polluted water which the results show that permanganate preoxidation obviously...
In this paper, the old simple Municipal solid waste (MSW) landfill pollution risk in China were analyzed. In order to control environment pollution, some countermeasures, such as constructing landfill cover, subsurface vertical barrier, installing bio-filter to reduce CH4 emission, pumping and treating the contaminated water, were working out and analyzed in detail.
The extensive clayization of Dexing copper mine is responsible for water and soil pollutions because of the oxidation of sulfide minerals. During the clayization, harmful elements such as As, S, Sb and Pb could be effectively released into the clay and water. Using the abundant spectral information of short wave infrared (SWIR), combining with the spectral absorbed index, SAM (Spectrum Angle Mapper)...
