H2S (hydrogen sulfide) was regarded as the research object in this study. The removal performance of two bio-trickling filters was compared. One is the counter flow one, a traditional bio-trickling filter, and the other is a newly self designed cross flow bio-trickling filter. A mixed culture of activated sludge was used as bacterial seed and the bio-film was developed by culturing the bacterial in...
For make full rational use of the packed media surface, the fluent software was used to the section area of the bio-trickling filter's inlet is enlarged and the outlet gradually converged. The enlarged cross-flow bio-trickling filter is characterized with low pressure drop and uniform distribution of gas and spray liquid. The filter inoculated with efficient Pseudomonas putida on the ceramic pellets...
Hydrogen sulfur was regarded as the research object in this study. Correlated research of biological treatment of hydrogen sulfide was investigated. Domestication in an aeration flask was employed to screen out the optimal bacteria (Thiobacillus). Na2S was used as the inducer in the domestication period. Gas-liquid phase joint inoculation method could start up biotrickling filter effectively. The...
A particular optimizing approach that aims at the modeling, analysis and design of integrated spiral inductors is addressed in this paper. The novel optimizing approach is based on analyzing the tapered inductor and symmetric inductor. With the optimizing approach, the advantages of tapered inductor and symmetric spiral inductor are combined and the Q-value and differential character of the inductor...
