    摘要： A constructed wetland system enhanced by immobilized laccase, it includes wetland plants, a matrix layer and a water distribution system, the wetland plants growing on the matrix layers, the matrix layer including a laccase catalyst and gravel, the laccase catalyst and gravel are distributed at intervals in a modular manner in a ratio of 1:5, the water distribution system is arranged on both sides of the matrix layer. The laccase catalyst is prepared by using a co-immobilization technology. The system improves the removal effect of hard-to-degrade organic matter in wastewater, and solves the problems of toxicity and stress of the hard-to-degrade organic matter existing in the prior art and the problems of matrix adsorption saturation.

    摘要： A composition for remediation of soil and groundwater containing halogenated compounds. The remediation composition includes an elemental iron-based composition, which may include activated carbon capable of absorbing the halogenated compounds with numerous pores impregnated with elemental iron. The remediation composition further includes a first bioremediation material including a blend of one-to-many organisms capable of degrading the halogenated compounds. The remediation composition includes an organic compound or polymeric substance and a second bioremediation material including a blend of one-to-many organisms capable of degrading the organic compound or polymeric substance over time (e.g., 20 to 365 or more days to provide a time release substrate-creating material or platform) into smaller molecules or compounds used by the organisms in the first bioremediation material while degrading the halogenated compounds. The organic compound may be a complex carbohydrate such as food grade starch, chitin, or other complex carbohydrate such as one with low water solubility.

    摘要： A method and a ventilation system includes ventilation ducts, a control system and at least one spray nozzle. The at least one spray nozzle is configured to spray a liquid mist onto at least one portion of an inner surface of the ventilation system. The liquid mist contains a culture of microorganisms adapted for biologically treating fat, oil and grease present on at least one portion of the inner surface of the ventilation system, thereby providing for partial biodegradation of the fat, oil and grease present on the at least one portion of the inner surfaces of the ventilation system.
