摘要： In preferred embodiments, the present disclosure relates to wells and methods of using the same. The disclosure refers to a method for reducing noxious gas from a location. A location containing hydrogen sulfide may be identified. The well may be packed with a reactive structural component composed at least partially of a metal oxide. The well may be inserted into the location containing hydrogen sulfide. A gaseous mixture is extracted from the location. The reactive structural component reacts with the hydrogen sulfide to remove it from the gaseous mixture being extract. A metal sulfide is a byproduct of this process. Often, the location may be a landfill. The metal oxide may be iron oxide. The gas being extracted may be methane.

摘要： A control system for controlling extraction of landfill gas from a landfill via a gas extraction system, the gas extraction system comprising well piping for coupling a plurality of wells to a gas output. The control system comprises a controller configured to: obtain a value indicating measured energy content of landfill gas collected at the gas output from the plurality of wells; determine whether the measured energy content is different from a target energy content; and in response to determining that the measured energy content is different from the target energy content: control a plurality of valves disposed in the well piping to change flow rates of landfill gas being extracted from at least some of the plurality of wells at least in part by changing degrees to which the plurality of valves are open.

摘要： A waste disposal system (30) with a waste receiver (32) for receiving pharmaceutical waste material. A locking assembly (34) is secured to a fixed surface and actuated from a locked configuration to an unlocked configuration. A lock cylinder of the locking assembly may extend forward of a front wall (44) of a receiver body (36) of the waste receiver to engage a locking feature of a cover (82) in the locked configuration. A cover retention feature (124) may prevent axial decoupling of the cover from the receiver body. The receiver body may be formed from two shells (62,64). A reaction agent (150) is positioned within the container volume and spaced apart from a bottom wall of the receiver body. The reaction agent may be positioned within the container volume between the lock passageway (94) and/or a solid receiver volume, and opposing sidewalls of the receiver body. A support may maintain the position of the reaction agent within the container volume.

摘要： A remote control system of a plant for managing the biogas catchment wells of a landfill in an automated manner by means of central software, adapted to optimize biogas production by increasing its flow rate and maximizing the concentration of methane therein. The plant has a plurality of extraction wells, which are organized in substations, and an infrastructure of controllers for data acquisition and data sending. Each well is associated with an infrastructure of sensors, an adjustment valve, and an actuator. The sensors are adapted to measure the volume percentage of methane % CH4, the volume percentage of oxygen % O2, the flow rate Q sucked in, and the applied negative pressure P of the well. The extraction wells of a substation are connected to a controller of the infrastructure of data acquisition and data sending for sending the values measured from the sensors to the remote control system (100) through a communication network. The remote management system receives the values measured from the sensors through the controllers, processes them, and based on predetermined rules generates the actuation commands of the actuators acting on the adjustment valves. The predetermined rules are based on a preference principle, according to which the well to be opened more is chosen based on its contribution compared to the other wells, and on an interference principle, according to which, in the case of two interfering wells, the control system chooses the well from which to suck more biogas based on an average performance index (IQ) of the wells.

摘要： THIS invention relates to a method of disposing of residues from the comminution and processing of ores. The method includes the steps of classifying the processing residues into a water permeable sand fraction and a tailings fraction and depositing the tailings fraction and the sand fraction to form a multilayer structure contained by at least one containment wall (14) with the sand fraction forming continuous channels (12) through the tailings fraction (10) to allow water contained in the tailings and sand to flow by gravity, through the sand channels, to water discharge points (16), and recovering the water (18) from the water discharge points.

摘要： An ecological reconstructed sponge structure of a strip mine dump includes a three-layered sponge ecological structure arranged on a groundmass layer of the dump. From bottom to top, the three-layer sponge ecological structure comprises a water-resisting layer, a water-containing layer and a topsoil ecological layer. A thickness of the water-resisting layer is 100˜200 cm, a permeability coefficient of the water-resisting layer is 0.35˜0.7 m/d, and a degree of compaction is 1200˜1400 KPa. A thickness of the water-containing layer is 150˜250 cm, a permeability coefficient of the water-containing layer is 10˜20 m/d, and a degree of compaction is 800˜900 KPa. A thickness of the topsoil ecological layer is 40˜60 cm. Soil layer thicknesses and water content may be monitored through a ground penetrating radar.
