A kind of recycled composite garden soil prepared by using construction waste and industrial waste

Abstract

The invention relates to regenerated compound landscape soil prepared on the basis of recycling of building rubbish and industrial waste as well as a preparation method of the regenerated compound landscape soil. The landscape soil is prepared from the following components in percentage by weight: 60-75 percent of soil separated from the building rubbish, 10 percent of regenerated sand stones, 10 percent of humus soil and 5-20 percent of burnt coal cinders. Since the main components of the regenerated compound landscape soil are the soil separated from the building rubbish and the regenerated sand stones, the building rubbish is effectively recycled, and the problems about disposal of the building rubbish and the deficiency of the landscape soil can be solved; meanwhile, as the industrial waste (the burnt coal cinders) is creatively used as a raw material, the sustainable development of resources is realized; the prepared regenerated compound landscape soil has good performance in water retention, fertilizer retention, breathable ability and water permeability; and plants cultivated by the regenerated compound landscape soil are good in the growth vigor and are luxuriant in foliages.

Description

technical field [0001] The invention relates to a regenerated composite garden planting soil, in particular to a regenerated composite garden soil prepared by resource utilization of construction waste and industrial waste. Background technique [0002] With the rapid development of urbanization and economy, cities have accelerated the speed of "metabolism", and a large number of old buildings have been demolished. In this process, a large number of "metabolites" that hinder urban construction - construction waste has been formed. According to statistics, construction waste has accounted for 30%-40% of the total urban waste. Construction waste is mainly composed of muck, crushed stones, broken bricks, waste mortar blocks, waste concrete blocks, waste glass, waste ceramics, waste asphalt blocks, waste plastics, waste metal materials, waste bamboo and wood, etc. At present, the main ways to deal with construction waste in my country are as follows: First, the construction was...

Problems solved by technology

However, although there are occasional reports on the use of construction waste in the current regenerated garden soil, due to the unreasonable configuration of its raw material components, the synergistic effect between the components is not fully considered, but the simple superposition of component functions is carried out, which often leads to Strong water and fertilizer retention capacity, but poor water permeability and air permeability; water and fertilizer retention ability becomes poor after water permeability and air permeability are guaranteed, and it is difficult to make both, so soil compaction, waterlogging or severe water loss often occur and frequent watering and irrigation are required. It is very easy to cause difficult plant germination, stunted growth, and rotten roots.
