This invention relates to the field of organic waste gas recovery and resource utilization technology, and particularly to a low-volume methane / VOCs co-recovery system, method, and application in oil and gas development processes. The system includes a waste gas generating device, a waste gas collecting device, a waste gas conveying device, and an adsorption storage device connected in sequence. The adsorption storage device is filled with layered adsorption materials, which include a layered adsorption layer of heavy components, a layer of intermediate components, a layer of light components, and a protective bed, stacked sequentially. This invention, based on the adsorption storage concept and utilizing the inherent potential energy of the oil and gas development process, achieves efficient recovery of methane / VOCs from intermittent emission sources, reducing greenhouse gas methane and VOCs emissions and improving oil and gas product yields.

The application provides a kind of water level fluctuation river beach zone degraded wetland Juncus effusus community directional recovery method, belongs to wetland water environment ecological management and landscape restoration technical field.The application includes the following steps: (1) the hydrological condition of river beach zone degraded wetland is investigated, and the target recovery area and the transplanting height and time of Juncus effusus are determined: the transplanting height of low-lying area is greater than or equal to 30 cm, and the transplanting is carried out in early May; the transplanting height of water level change area is greater than or equal to 25 cm, and the transplanting is carried out in early May; the transplanting height of humid area is greater than or equal to 20 cm, and the transplanting is carried out in mid-late May; (2) the degradation degree of Juncus effusus in the target recovery area is investigated, and the transplanting density of Juncus effusus is determined: the natural recovery is carried out in slight degradation area, 20-30 plants / m 2 are transplanted in moderate degradation area, and 40-60 plants / m 2 are transplanted in severe degradation area.The application can not only improve the growth adaptability of Juncus effusus, but also enhance the ecological function of wetland, and provide a new solution for ecological protection and sustainable development.
