A device for reducing seepage and diffusion of landfill seepage based on forward osmosis

Abstract

The invention discloses a device for reducing seepage and diffusion of garbage leachate based on a forward osmosis effect. The device is composed of a permeable membrane protection shell, a permeable membrane and a cover plate, wherein the permeable membrane protection shell is bottle-shaped, and a plurality of through holes are formed in a side wall of the permeable membrane protection shell; the permeable membrane is of a hollow cylinder shape; the top end of the permeable membrane is embedded into a bottle shoulder of the permeable membrane protection shell, and the bottom end of the permeable membrane is embedded into a bottom surface of the permeable membrane protection shell; an NH4HCO3 solution is stored in the permeable membrane protection shell; and a cover plate is arranged at a bottleneck of the permeable membrane protection shell. According to the device disclosed by the invention, water in the garbage leachate is absorbed so that seepage and diffusion of the seepage and diffusion are reduced, and the effect of preventing a pollution range of the garbage leachate from being enlarged is realized; and the permeable membrane protection shell with a hole can protect the permeable membrane from being squeezed and damaged by solid garbage. By adopting the device disclosed by the invention, a process of reducing the seepage and diffusion of the garbage leachate is realized by utilizing the spontaneity of the forward osmosis effect, and other power equipment is not needed, so that the device has the advantage of low energy consumption.

Description

technical field [0001] The invention relates to the field of garbage seepage treatment, in particular to a device for reducing seepage and diffusion of garbage seepage based on forward osmosis. Background technique [0002] Due to the residual moisture of the garbage itself or the impact of rainfall, the landfill will produce a certain amount of garbage seepage. Landfill leachate is a complex solution containing water, organic compounds, heavy metals, organic or inorganic nitrogen and a large amount of dissolved solids, and its treatment is a major problem. After the landfill seepage is produced, it will further seep and spread, which may continue to increase the scope of its pollution, affecting places far away from the landfill, which is not conducive to environmental protection and the normal safety of humans and other organisms (including crops); On the one hand, landfill leachate also directly affects the anti-seepage treatment of landfills. When there is more landfill...

Problems solved by technology

After the landfill seepage is produced, it will further seep and spread, which may continue to increase the scope of its pollution, affecting places far away from the landfill, which is not conducive to environmental protection and the normal safety of humans and other organisms (including crops); On the one hand, landfill leachate also directly affects the anti-seepage treatment of landfills. When there is more landfill leachate, the cost of landfill leachate control system construction will increase accordingly.
