Abstract

The invention discloses a local reinforcement treatment method for preventing seepage in a garbage factory, which includes, in the first step, artificial refrigeration is adopted at the seepage place of the garbage landfill, a certain number of freezing pipes are arranged around the seepage place, and a low-temperature refrigerant agent is sent into the Formation, the water in the surrounding soil is frozen into ice and cemented together with the soil to form a freezing curtain, using a closed freezing curtain to block the seepage of leachate; the second step: use microbial grouting reinforcement under the freezing curtain , use the grouting pipe to introduce microbial solution, fixative solution and cementation solution, and react to produce calcium carbonate to fill the pores between soil particles and cement the soil particles to form a composite soil with high bearing capacity and low permeability. The invention has the advantages of high cost performance, strong stability, quick plugging effect, strong plugging ability and wide application range, can effectively control the seepage of leachate, and block the serious pollution of groundwater environment caused by garbage leachate, and can be widely used in The landfill project is under construction.

Description

technical field [0001] The invention relates to a treatment method for garbage seepage, in particular to a local reinforcement treatment method for preventing seepage in a garbage factory. Background technique [0002] Garbage is solid waste generated in human daily life and production. Due to the large amount of discharge, the composition is complex and diverse, and it is polluting. At present, the disposal methods of waste mainly include high-temperature composting, incineration and sanitary landfill. The high-temperature composting method is mainly used for the treatment of perishable organic matter in domestic waste, such as: kitchen waste, fruit peels, etc. The investment is low, the technology is simple, and the organic matter can be reused as fertilizer after decomposition to achieve the recycling of resources, but the requirements for waste classification High, the odor produced during the aerobic decomposition process will pollute the environment, and the high cost ...
