Environment restoring method for manufacturing ecological crust by adopting anaerobic digestion residuals

Abstract

The invention discloses an environment restoring method for manufacturing an ecological crust by adopting anaerobic digestion residuals. The method comprises the following steps of: 1) obtaining a substrate: performing solid-liquid separation on the anaerobic digestion residuals by utilizing a solid-liquid separation device to obtain biogas residues; 2) adjusting the substrate: adding auxiliary materials, such as medical stone and water-retaining agent, into the biogas residues, and mixing uniformly; 3) forming the crust: placing the materials into a mould and pressing into the crust; and 4) outdoor paving: placing seeds into a seedling culture cave of the crust, placing the crust into different vertical habitats according to environmental condition to enable the seeds to automatically sprout and grow, and with the growth of the seedling and the weathering of the crust, integrating the plant, crust and soil into a whole. The method provided by the invention has the advantages of simpleness and easiness in operation, convenience in operation, environment-friendly property, and resource-saving property, and is suitable for the control of desertification and the restoring, rebuilding and improving practice of local ecology.

Description

technical field [0001] The invention relates to the field of ecology, and more specifically relates to a method for using anaerobic fermentation residues as substrates to prepare ecological crusts to restore the environment. Background technique [0002] my country's arid and semi-arid areas account for about 50% of the country's land area. The precipitation in this area is small, the evaporation is large, the vegetation is scarce, and natural disasters are frequent. The vegetation degradation and desertification caused by drought, wind and sand and soil erosion are becoming more and more serious. Huge direct and indirect economic losses also threaten people's normal production and life. With the implementation of the country's western development strategy, it has become an important measure to improve the ecological environment in arid and semi-arid areas by adopting vegetation restoration projects to prevent and control desertification. [0003] Usually, the occurrence of ...
