The effect of loaded pellets in high voltage pulse discharge was investigated. There were some changes in the surface characteristics of different pellets with loaded catalysts. The specific surface area of the pellet loaded with ferric hydroxide increased and the pellet loaded with titanium dioxide decreased. Pore volume and pore size of loaded pellets were small. The adsorption of phenol on the...
Degradation of phenol by streamer corona plasma in aqueous solution with suspended TiO2 was conducted. The experimental results present that the addition amount, the crystal size and structure of TiO2 influenced the phenol degradation. In this paper phenol degradation increased with the addition amount of TiO2 in the range of 0-0.4 g/L; the highest degradation rate of phenol was obtained when Degussa...
This paper studies the estimation of river pollutant discharge rate. With comprehensive analysis of primary factors impacting water quality, say pollutant concentration, water flow velocity, water discharge amount and natural degradation, we build an estimation model of river pollutant discharge rate based on one-dimensional water quality model. Considering that the distribution of waste outlets along...
The decomposition of high concentration pentachlorophenol (PCP) loaded on granular activated carbon (GAC) was studied by dielectric barrier discharge (DBD) plasma. The effects of discharge voltage, treatment time, gas kinds and flow rate on PCP degradation efficiency were discussed. The results indicated that increasing discharge voltage and treatment time could enhance the degradation efficiency...
Pulsed arc electrohydraulic discharge process (PAED) has been studied for the removal of some of organic pollutants. Firstly, the destruction of para-chlorophenol by PAED system was studied under some different experimental conditions (ionic strength, pH, conductivity and organic initial concentration) in a 5.6-L reactor with the following configuration: 2.9 kV of potential, 140 muF of capacitors...
