Novel pollutant control equipment, which were called integrated pollutant control equipment, consisted of bag filters and activated carbon (AC) absorbers. The AC absorbers were put forward to absorb the additional pollutants between the old and new emission standards to satisfy Chinese emission standards. The absorbers could be fixed (mobile) bed, annular column, or fluidized bed. The numerical method...
Low, medium and high densities of western flower thrips [Frankliniella occidentalis (Pergande)] were established in three greenhouses, in 1994 and 1995, to investigate the effects of thrips on growth, photosynthesis and productivity of greenhouse sweet pepper. Sweet pepper fruit was very susceptible to cosmetic injury which resulted in a reduction of the commercial grade of the fruit (quality). ...
To enhance biological nitrogen removal from wastewater, a logical approach is to increase the biomass concentration in anoxic zones. For activated sludge processes, the introduction of some packing materials for the attached growth of biofilm is a feasible and simple approach to increase biomass. A novel fibrous carrier is considered to be one of the most attractive and competitive packing materials...
