The invention discloses a composite ecological restoration technology suitable for an open-pit coal mine waste dump. The technology comprises the following steps: (I) planting water-saving and convergence-increasing plants: sowing the water-saving and convergence-increasing plants to the open-pit coal mine waste dump to be restored in a shrub and grass seed broadcast sowing manner; (II) preparation and spraying of a prokaryotic microbial strain: culturing the separated and purified pseudoarthrobacter sp.xwn1, microbacterium sp.xwn2 and Acinetobacter sp.xwp1, carrying out enlarged culture on the cultured microbial agent, and then spraying and applying the microbial agent to the open pit coal mine waste dump after the microbial agent is applied to the open pit coal mine waste dump after the microbial agent is applied to the open pit coal mine waste dump after the microbial agent is applied to the open pit coal mine. By using the composite ecological restoration technology, the carbon sequestration capacity of plants is promoted, the organic carbon content of soil is increased, and ecological carbon sequestration restoration of the open pit coal mine waste dump is facilitated.

To provide a garbage collection work notification system capable of notifying users with sufficient alert effectiveness that a garbage truck is approaching a garbage dump site for each type of garbage.SOLUTION: A garbage collection work notification system includes a management server, an on-board terminal device, and a user terminal device. The management server acquires and stores the trajectory of each work vehicle using location information transmitted from each on-board terminal device. The management server calculates the required time from the current location of the work vehicle on a patrol route of garbage dump sites to each garbage dump site for each type of garbage used by each user based on the past trajectory of the work vehicle on the patrol route, and then sends a work vehicle approaching notification to the user terminal device of each user who is registered for each uncollected garbage dump site located within a predetermined time distance from the current location of the work vehicle. This minimizes the frequency of work vehicle approaching notifications, prevents a decline in alert effectiveness due to habituation, and ensures that notifications are delivered with sufficient alert effectiveness.SELECTED DRAWING: Figure 1

The application provides a flexible drainage ditch construction method, comprising the following steps: S1, designing the drainage ditch trend and size according to the gas collection shaft distribution in the landfill; S2, excavating the trench foundation pit of the drainage ditch by the excavator, and filling the broken stones in the excavated trench foundation pit; S3, excavating the foundation pit by using the shaped excavator, and shaping the broken stones into the trench shape; S4, processing the geocell according to the trench section shape, and laying the geocell in the trench; S5, filling the plain concrete in the geocell and smoothing; S6, laying the geotextile on the upper surface of the plain concrete before the plain concrete solidifies, and then pouring the plain concrete again and curing the plain concrete. The broken stones are filled in the foundation pit, the settlement stress of the landfill is resisted by the broken stones, the drainage ditch is prevented from being damaged, the drainage ditch can bear a certain deformation tensile stress through the geocell, the overall stability of the drainage ditch structure is maintained when the settlement occurs, and the anti-seepage performance of the landfill can be further improved.

This invention relates to the field of solidification materials, and discloses a solidification material that combines seepage prevention and pollution remediation functions with its application. The solidification material comprises a first component, a second component, and a third component; the first component comprises cement; the second component comprises slag; and the third component comprises hydrotalcite and a piezoelectric catalyst. Through the rational matching and compounding of its components, this solidification material forms a synergistic effect, significantly improving the crack resistance, seepage resistance, and corrosion resistance of vertical seepage barriers. It can simultaneously meet the requirements for seepage prevention performance and has the function of remediating heavy metals and organic pollution, thereby achieving the goal of long-term vertical seepage prevention in solid waste dumps. Furthermore, it simultaneously realizes the reduction and utilization of bulk solid wastes such as blast furnace slag and fly ash, resulting in excellent economic and equipment benefits.
