Research Interests

1.      Environmental photocatalysis

_______ Synergistic Effect of Hybird Magnetism-Photocatalytic Reaction System

Magnetic field was introduced into the photocatalytic system and the synergetic effect between photocatalytic and magnetic function was studied. A series of light active phtocatalysts have been developed and photocatalytic reaction of each for organic pollutants degradation was studied in the magnetic field photocatalytic system. The synergetic mechanism between photocatalytic system and magnetic function was established by studying the magnetic effect on the trapped electron and the hydroxyl radicals produced in the photocatalytic process within magnetic field. The results suggest that the phtocatalyst degradation efficiency of organic pollutants has increased evidently, with  magnetic function focusing mainly on the increase in the production and concentration of hydroxyl radicals and the intersystem transition of the pairs of electrons and holes to lower the chance of recombination of them and prolong the life expectancy of the electrons generated in the photocatalytic process. We aimed to solved the problem of the low efficiency and low mineralization of the treatment of photocatalysis and set up a theoretical model and a new technique flow for the efficient degradation of pollutants.

2.      Environmental  Microorganism Catalysis

              _______Removal of H2S in waste gases by an activated carbon bioreactor

   A type of bioreactor packed with granular activated carbon (GAC) as support material was used for the removal of high concentrations of H2S in waste gases. Experiments about the physical adsorption capacity of GAC matrix., retention time and pressure drop were carried out; the abilities of bioreactor to buffer shock loading and removal efficiency (RE) of long-term operation were also investigated. Besides, the kinetics analysis of single-stage biodesulfuration was also studied. The results showed that GAC matrix provided high bacteria adsorption capacity, showed a superior resistance to shock loading and allowed good operational control in area of pressure drop. When the retention time was 25 s and influent concentration of H2S was 100 mg L-1, the REs were beyond 98%. An average 96.8% RE was achieved during the long-term operation for GAC bioreactor under different concentrations up to 120 mg L-1 by keeping constant flow rate. No acidification was observed in the GAC bioreactor during the long-term operation. The kinetic analysis showed that the maximum removal rate and the saturation constant in the GAC bioreactor were 666.7 mg(H2S) (Ld)(-1) and 20.8 mg L-1, respectively. The response of bioreactor to shock loading operation showed that GAC bioreactor has gotten a good buffering capacity to withstand fluctuating loading conditions.

     _______Removal of H2S by Thiobacillus denitrificans immobilized on different matrices

   Biological removal of high concentrations of H2S was studied using the immobilized Thiobacillus denitrificans with peat moss, wood chip, ceramic and granular activated carbon (GAC) separately. Experiments on the physical adsorption capacity of matrix, retention time and pressure drop were carried out; the ability of bioreactor to buffer shock loading and the removal efficiency with different packing materials were also investigated. Besides, the kinetics of single-stage biodesulfuration was analyzed. The results showed that GAC provided higher bacteria adsorption capacity, showed a more resistance to shock loading and allowed better operational control with respect to pressure drop than other inert carriers. When the retention time was changed from 30 to 100s at an influent concentration of 100mg/L of H2S, the removal efficiencies were above 98%; when the inlet concentration of H2S were changed from 110 to 120mg/L, an average 96.8% removal efficiency was achieved during the long-term operation for GAC bioreactor. Next to GAC, wood chip was found to be a good packing material; however, peat moss and ceramic had limited effectiveness and their removal efficiencies were less of 90%. The kinetic analysis showed that the maximum removal rate and the half-saturation constant of the GAC bioreactor were 666.7mg (H2S)/L and 20.8mg/L, respectively.

        _______Biological elimination of hydrogen sulfide by immobilized Thiobacillus denitrificans

    Thiobacillus denitrificans was immobilized with Ca-alginate to produce pellet packing materials for a packed column biological fixed bed that controls hydrogen sulfide emission. The effects of operating parameters such as temperature, pH value, inlet gas concentration and flow rate on the removal efficiency were studied. The kinds and contents of metabolic products in the biological fixed bed were measured. The results showed that the optimal temperature and pH value required to remove hydrogen sulfide were 25-5-40and pH=6.0-7.5,correspondingly the hydrogen sulfide removal efficiency greater than 90% if inletH2S concentration was below 6×10-5mg/L,and pH value drop was insignificant in this fixed bed. The hydrogen sulfide removal efficiency was affected dramatically bythe inlet gas concentration and flow rate. The biological fixed bed had a hydrogen sulfide removal efficiency remained above 95% when the inlet hydrogen sulfide concentration was below 3×10-5mg/L at 35 L/h of flow rate. The element sulfur as a main product prevented acidification of the biological fixed bed, which maintained the stability of the operation.

              _______Treatment of sulfur-containing waste gases by microbial technology

   Limitations of traditional methods in treating industrial sulfur containing waste gases are pointed out. Advantages of microbial technology are introduced. Characteristics of microbial strains and bases of selecting microbial strains for inorganic and organic desulfurization are discussed. Mechanisms of microbial desulfurization are analyzed. Some biofilm desulfurization methods including biofilter, biotricking filter and biosorb and their applications in industrial fields at home and abroad are reviewed  Existing problems, developmenttrends and application prospects ofmicrobial desulfurization technology are deliberate.

3.      Technology of Comprehensive Utilization of solid wastes

          _______System of naturalization of 150-thousand-ton per year garbage of Xi’an city

Based on character, current technologies of treatment and disposal of solid waste garbage, condition of the financial and the changing phases of society of Xi’an city were investigated overall and analyzed scientifically, a new system of naturalization of 150-thousand-ton per year garbage of Xi’an city was set up and the feasibility of system putting in practice was studied.

          _______Flocculant made from Red Mud and its Application on Treating Paper Making Black Liquid                                                        

 

The red mud originated in the Shanxi Aluminum Plant as byproduct of aluminum oxide industry, has been studied to make inorganic polymer complex flocculant (PAFSS) by refluxing red mud in 40% H2SO4 and adding a small amount of sodium silicate solution. The optimal production engineering and operational conditions have been investigated by means of manufactories experiments. The optimal operational conditions, including dosage ratio of red mud (g) to H2SO4 (ml, wt. 40%), pickling time, reaction temperature, molar ratio of Fe to Si and synthesis ageing time are 100:600, 3h, 90, 2:1, 2h, respectively. The production was used to treat paper making black liquid in the function of pH and the dosage of the flocculant, and the best flocculation value attains at pH4, 80mg/L, respectively. The removal rates of COD, turbidity, and chroma were 48.5%, 96.5%, 94.2%, respectively.

          _______Treatment of Chromium-containing wastewater with activated red mad

The treatment of chromium-containing wastewater with activated red mud which is by-produce of aluminum oxide industry were experimentally investigated; The influence of the activated temperature of red mad, dosage and contacting time on treatment efficiency were discussed. The results show the rate of removing chromium is greater 99% in the range of Cr3+300mg/L when the red mud activated for 4 hour at 873K were added into chromium-containing wastewater with mass ratio of red mud to chromium 200:1, and the outlet water reached national effluent discharge standard. As for chromium()-containing wastewater in the range of Cr6+300mg/L, the outlet water also reached national effluent discharge standard by using red mud treatment after adding FeSO4,.

           _______Microwave synthesis and desulphurization of fly ash and red mud desulfurizer

With the development of aluminum oxide industry in the country, a series of environmental problems caused by red mud, a harmful byproduct of highly alkalinity, cannot be neglected. Simultaneity, with the increasing of the energy requirement, the quantity of coal burned is increasing; a series of environmental problems caused by fly ash is serious increasingly. It is essential either to find suitable ways to safely dispose of red mud, or to suggest novel uses.

Due to its high alkalinity and porosity of red mud and porosity of fly ash, the red mud originated in the Shanxi Aluminum Plant and the fly ash originated in someone electricity plant, have been studied to make inorganic desulfurizer to removal SO2 from waste Gas by red mud and fly ash and adding sodium silicate and so on. The optimal production engineering and operational conditions have been investigated by means of different agglomeration and manufactories and orthotropic experiments The optimal operational conditions, including dosage ratio of red mud (g) to fly ash (g) to sodium silicate (g) to sodium carbonate to water (g),power of micro-wave oven, and synthesis ageing time are 10035302050 , 800 w, 6 min, respectively. The percentage of SO2 removed is 74%, when the height of column is 25cm and the concentration of SO2 is 7000 mg/m3.

The effects of the height of column and the concentration of SO2 on the adsorption process have been studied by measuring the percentage of SO2 removed at different factors.
