摘要： A solution for irradiating a flowing fluid through a channel with ultraviolet radiation is provided. Ultraviolet radiation sources can be located within the channel in order to direct ultraviolet radiation towards the flowing fluid and/or the interior of the channel. A valve can be located adjacent to the channel to control the flow rate of the fluid. A control system can control and adjust the ultraviolet radiation based on the flow rate of the fluid and a user input component can receive a user input for the control system to adjust the ultraviolet radiation. The ultraviolet radiation sources, the control system, the user input component, and any other components that require electricity can receive power from a rechargeable power supply. An electrical generator located within the channel can convert energy from the fluid flowing through the channel into electricity for charging the rechargeable power supply.

摘要： The present invention relates to a method and a device for controlling pollutants in basin water resources cycling utilization in agricultural activity areas. The method includes: providing an acidification tank, an aeration tank and a multi-media constructed wetland connected in sequence, which are 4˜10 m far from basin revetment, feeding basin water into the constructed wetland, adsorbing or degrading heavy metals and organic pollutants by the constructed wetland, and then transporting the treated basin water to the agricultural activity areas. The present invention effectively controls the content of heavy metals that will enter the agricultural activity areas, fundamentally reduces the content of heavy metals in the crops, promotes the growth of the crops, maintains sustainable and healthy development of agriculture, and therefore guarantees human health and safety.

摘要： Leachate remediation is performed by synergistic chemical oxidation and photocatalytic-oxidation enhancer system (SCOPES) of municipal landfill leachate to a level that is safe for disposal within regulatory guidelines. The physico-chemical (chemical, spectroscopic, elemental, microstructural and thermal) characteristics of the pre- and post-treated landfill leachate have been investigated to examine the utility of advanced oxidation (AO) processes such as SCOPES to decontaminate the municipal landfill leachate and/or toxic organic wastewater. The experimental results demonstrated successful lowering of chemical oxygen demand (COD) and UV-Vis absorbance for constituent contaminants in the leachate and/or wastewater solutions.
