Method for reforming closure pile for refuse landfill site

Abstract

A method for reforming a closure pile for a refuse landfill site belongs to the technical field of soil improvements, biological cultivation and revegetation. The method is characterized in that wildflower groundcover plant seeds, and includes: screening groundcover plant seeds; matching; coating; preparing water-holding gel resin; making ditches on the landfill site; fertilizer scattering; spraying gel resin to the fertilizer; and sowing seeds. The method has the advantage that large-scale wildflower groundcover plant seeding is performed on a final earth layer of the dry and barren closure pile of a beach type refuse landfill site so that environmental beautification and refuse landfill site closure pile reformation are achieved by the simple and economical method. By the method, seed germination rate is high, seeds grow well, natural wildflower groundcover plant landscape with rustic charm is easy to form, and conditions for large-scale effective reform of the refuse landfill landscape and promotion of revegetation are created. The closure pile is simple in structure and low in cost, and the method is simple in operation and effective.

Description

technical field [0001] It belongs to the field of soil improvement technology, biological cultivation and vegetation restoration technology. To be precise, it is a method for realizing low-cost sowing and high germination rate ground cover plant sowing and germination technology on the arid and barren soil layer of the garbage landfill. [0002] Background technique [0003] The landfill adopts the method of sanitary landfill (Sanitary landfill) for waste disposal. Sanitary landfill uses engineering means and takes effective technical measures to prevent leachate and harmful gases from polluting water and the atmosphere, and compact the waste to reduce its volume. It is a method of land disposal garbage that is minimized and regularly covered with soil so that the whole process has no harm to public health safety and environmental pollution. At present, the sanitary landfill treatment rate of municipal solid waste in my country has reached more than 85%. The number of lan...

[0005] In order to save costs, the final covering soil of tidal flat landfills is usually blown mud from tidal flats or deep soil from tunnels, which has the characteristics of poor water retention, high salinity and low organic matter content, etc. The germination rate of the plant sowing method is extremely low, and individual germinated plants are difficult to compete with vicious weeds due to lack of nutrients. At the same time, if high-intensity maintenance is carried out to improve the germination rate and growth, the initial investment cost will be greatly increased, which is not conducive to landfill closure.
