Do an oxidation experiment by use the ozone technology on ammonium sulfite which is produced as a byproduct in the desulfurization by ammonia absorption process, researched the influences to the oxygenation efficiency of ammonium sulfite under different reaction temperature, aeration, oxidation time, pH value and the initial ammonium sulfite concentration, found out a method and oxidation condition...
The biosorption characteristics of Pb(II) from aqueous solution using freeze-dried biomass of Neosartorya hiratsukae(M7) were investigated as a funtion of pH, contact time and initial concentration. The optimal pH for adsorption of Pb(II) was determined bo be 6.0. The pseudo-second-order kinetic model was found to be well suited for the adsorption process. Langmuir model fitted the equilibrium data...
The efficiency of dust collection in an electrostatic precipitator is mainly determined by its electric operational parameters which depends on the design and arrangement of the corona and collecting electrodes. In this paper, experiments of fly ash purification are carried using the transverse plate ESP system (the laboratory scale transverse plate electrostatic precipitator self-designed). The influence...
Effects of formaldehyde degradation using strong ionization discharge were studied. A majority of gas molecules in the air such as O2 and H2O were ionized and maken into OH ·of high concentration using strong ionization discharge method to carry out formaldehyde removal experiment without catalyst and absorbent. Some factors such as exerted voltage, initial concentration, fume flow, which affect the...
