摘要： Polymeric sorbents for aldehydes including formaldehyde are provided. More particularly, the polymeric sorbents are a reaction product of a divinylbenzene/maleic anhydride precursor polymeric material with a nitrogen-containing compound. The nitrogen-containing compound is covalently attached to the resulting polymeric sorbent. Additionally, methods of sorbing aldehydes (i.e., aldehydes that are volatile under use conditions) on the polymeric sorbents and compositions resulting from the sorption of aldehydes on the polymeric sorbents are provided. The polymeric sorbents typically are porous with the pores often being in the size range of mesopores and/or micropores.

摘要： A method for treating powdered activated carbon (PAC) and/or coal combustion residues (CCRs) by heating at least one of a spent PAC and/or a CCR to separate at least one heavy metal from the at least one of the spent PAC and/or the CCR to create a clean stream and a heavy metal stream, combining the heavy metal stream with a water soluble alkaline-earth metal sulfide to create a combined stream, and removing at least a portion of the at least one heavy metal from the combined stream. The heating may further include heating the at least one of the spent PAC and/or the CCR in an inert atmosphere. Further, the combining may include combining the heavy metal stream with the water soluble alkaline-earth metal sulfide and a catalyst and/or a surfactant or hyperdispersant.

摘要： [Object] To perform a magnetic decomposition treatment by effectively utilizing smoke emissions.[Solution Means] When an opening 112 is opened and hot air is blown by a hot air gun 40, the waste is thermally decomposed inside the thermal decomposition treatment chamber 110. When smoke emissions generated by the thermal decomposition pass through a shower 210 and a swashplate filter 220 of the filter section 200, a temperature thereof is lowered and tar is removed, and then the smoke emissions pass: through a blower 230, and when the smoke emissions pass through a water tank filter 240, tar is further removed, and moisture is removed by a cloth filter 250. Thereafter, odor is eliminated by a zeolite filter 260 and an activated carbon filter 270, and then, from an intake duct 30, and the smoke emissions are fed to the thermal decomposition treatment chamber 110. No new matter was added in the amendment.

摘要： Methods and systems for bioremediation of heavy metal contaminants in waste materials (e.g., sludge and combustion wastes from a coal-fixed power plant). The systems described in the present application include at least one waste treatment unit (e.g., a flue gas cleaner or a waste lagoon) that includes one or more selected bacterial strains disposed therein consume and/or reclaim at least a portion of the heavy metal in the combustion wastes. Methods include inoculating a waste treatment unit with one or more selected bacteria that consume and/or reclaim at least a portion of the heavy metal in the combustion wastes. Methods may include periodic reinoculation of the waste treatment unit with fresh bacteria and period recovery of the bacteria from the waste treatment unit.
