摘要： The integrated device for adsorptive purification and catalytic regeneration of VOCs is provided and includes a filtration adsorption coupling filter, a catalytic combustion regeneration box and a housing, where the housing includes a filter inner cavity and a combustion inner cavity that are communicated in sequence. The VOC exhaust gas is adsorbed and filtered by the filtration adsorption coupling filter. Moreover, under an operating condition of desorption regeneration, the catalytic combustion regeneration box is utilized to perform thermal desorption and regeneration on the filtration adsorption coupling filter, and catalytically combust and purify the VOC exhaust gas obtained by thermal desorption.

摘要： A filter element for coupling adsorption and regeneration of volatile organic compounds and a purification device are provided. The filter element includes a filter element body, a photocatalytic mechanism and adsorption-filtration body(s). The adsorption-filtration body(s) may be of a hollow columnar structure where the photocatalytic mechanism is located. VOCs are quickly adsorbed by the adsorption-filtration body(s), then thermal desorption regeneration is performed on the adsorption-filtration body(s) during a time interval of stopping discharging of the exhaust gas, and a photocatalysis technology is used to cyclically purify the thermally desorbed VOCs, which achieves the synergy of high-density and purification in the two technologies. Furthermore, it takes full advantages of high adsorption, filtration and purification efficiency, low photolysis catalysis costs, and easy operation and maintenance of the on-site regeneration. The filter element has the technical effects of a compact structure, high purification efficiency, recyclable adsorption-filtration body(s) and low costs.

摘要： Provided is a portable XRF data screening method for heavy metal contaminated soil, relating to the technical field of heavy metal contamination test. The method includes the following steps: (1) laboratory test; (2) XRF test; and (3) calculation of a recheck interval: dividing test data into four areas by a contaminant screening value Xc as a horizontal line and a correlation-derived site screening value as a vertical line to calculate the recheck interval. The method is simple and efficient, and is beneficial to saving investigation costs and shortening a project cycle.
