Abstract: A system and method for combined microorganism degradation and air sparging-soil vapor extraction (AS-AVE) of oil-containing sludge can include a microorganism-adding unit, an AS-SVE unit, a metering-feeding layer, a mixing layer, a material discharging layer and a crawler-type conveyor. In some embodiments the microorganism-adding unit and the AS-SVE unit can include a microorganism storage tank and an AS-SVE storage tank. In some embodiments, the metering-feeding layer can include a valve, a pressure gauge, a flowmeter, a feeding chamber. In some embodiments, the mixing layer can include pipeline connectors and a stirrer. In some embodiments, the material discharging layer is mainly for transporting the treated soil away. The system can remove petroleum, petroleum hydrocarbons, volatile organic compounds (VOCs), and degradable and extractable contaminants from oil-containing sludge by a method combining microorganism degradation, mechanical stirring, AS-AVE and the like, thereby achieving soil remediation and automatic treatment in a large scale.

Abstract: Provided are a silicate modified manganese-based material and a preparation method and application thereof. The silicate modified manganese-based material has a nanoscale needle like structure, and is prepared from a solution containing a manganese source and a soluble silicate source through an oxidation-reduction reaction and then a hydrothermal reaction. The manganese source includes a divalent manganese source and a heptavalent manganese source, with Mn (II) and Mn (VII) in a molar ratio of 0.5-5.5 to 1. The present disclosure uses silicate to regulate manganese oxides, significantly reducing the particle size of the manganese-based material, generating manganese vacancies, and changing the surface manganese valence state. An advanced oxidation system formed by the silicate modified manganese-based material and an oxidant has high removal rate and reaction rate for various organic compounds.

Abstract: A multi-objective optimization method for groundwater pollution monitoring network, which mainly includes four steps: groundwater numerical value simulation, groundwater vulnerability assessment, the establishment of the monitoring network optimization model, and the solving of the optimization model. The core of the method is to establish a multi-objective optimization model aimed at establishing the least monitoring wells, monitoring the maximum pollutant concentration, and monitoring the maximum regional vulnerability value. Solving the optimization model by the algorithm and considering the relationship between the quality error and the number of monitoring wells comprehensively to determine the well number and location of the monitoring network.
