Authors: Meng Xue Zheng , Cao Xiang Sheng , Li Jie Rui
Published: January 2011

The effects of molybdenum (Ⅵ) on the denitrification efficiency of activated sludge process were investigated with batch tests. The results indicated that up to 5 mg/L of Molybdenum (Ⅵ) concentrations in the liquor of activated sludge process could accelerate the nitrate removal rate, exhibiting maximum stimulation at 1 mg/L. Up to 4 mg/L of Molybdenum (Ⅵ) concentrations, the COD removal efficiency was enhanced. Up to 1mg/L of Molybdenum (Ⅵ) concentrations, the TTC-DHA was enhanced but higher concentration showed inhibitory effects. Based on the integrated effects of Molybdenum (Ⅵ) on nitrate and COD removal with the TTC-DHA change, 1mg/L of Molybdenum (Ⅵ) is proposed as the best concentration for denitrification of activated sludge.

Published: January 2011

An improved two – phase contact oxidation adsorption integrated bioreactor (CABR) was used to treat mixed wastewater from copper mine. The CABR was made up of a biofilm reactor and an activated carbon reactor. Polyacrylonitrile balls (20 mm diameter, 260 m2/m3 specific surface, 90% porosity) were filled into the contact oxidation reactor as biofilm attaching materials. Hydraulic residence times (HRT) of the two contact oxidation reactor were 1.5 hr and 1.2 hr, separately. Relevant ratio of aeration and water of the two contact oxidation were 5:1 and 3:1. From the long-term operation, the average removal efficiencies of chemical oxygen demand (COD) and ammonia nitrogen (NH4+-N) were 84.1% and 71.3% respectively. Two – phase contact oxidation can achieve the higher removal efficiency and the lower power consumption. Additionally, the activated carbon reactor can significantly remove heavy metal.

Published: January 2011

The effects of various extractants removing Cr from the soil of chromite ore processing residue (COPR) deposited sites were studied in order to select the optimal extractant agent. The effects of this agent on the removal of Cr(VI) and Cr(III) in the contaminated soil were also investigated. The results showed that organic complexing agents had higher removal efficiency than that of inorganic complexing agents due to the high content of Cr(III) in the soil(90.3%). The Cr removal of citric/sodium citrate (mole ratio: 1:1) was 35.95% in 24h. The reason why citric/sodium citrate removed more Cr than other agents is that citric can solubilize the mineral matrix, compete for the surfaces sites to desorb Cr(VI) and remove Cr(III) by its complexation. The concentration radio of Cr(VI) and Cr(III) in the initial soil was 0.11. Thus improving the removal of Cr(III)is the key point of improving the total Cr removal.
