Embodiment 1

[0028] Example 1 A method for in-situ ecological restoration of steel slag hills based on discarded steel slag piles in the northern region

[0029] 1. Test points

[0030] The site for the vegetation restoration pilot experiment is the steel slag yard in the Taizi River Basin in Benxi. The steel slag storage yard in the Taizi River Basin in Benxi is formed by piled up abandoned steel slag into a steel slag mountain. According to the soil content and geographical location of the steel slag mountain, the steel slag mountain is divided into four areas: the top of the steel slag mountain, the body of the steel slag mountain, the foot of the steel slag mountain and the steel slag mountain surrounding area. The top of the steel slag mountain and the body of the steel slag mountain basically have no soil, and the composition is steel slag. The soil content of the foot of the steel slag mountain and the area around the steel slag mountain reaches more than 80%.

Abstract

The invention discloses a method for in-situ ecological restoration of a steel slag mountain heaped with waste steel slag in the northern area and belongs to the technical field of ecological restoration. For restoration areas of the peak of the steel slag mountain and of the body of the steel slag mountain, and matrix concrete is first sprayed on the surface of the steel slag mountain, and surface concrete containing mixed seeds of bluegrass, ryegrass and red fescue is again sprayed; for the foot and peripheral restoration areas of the steel slag mountain, nutrient soil containing rhizophagusintraradices, funneliformis mosseae and a rhizobium agent is added to the soil of the restoration areas, three plants including festuca arundinacea, lespedeza and rhus typhina are planted, and earthworms are introduced into the soil. The method has simple operation, the plant survival rate is up to 92%, the steel slag mountain can be maximally green again in a short time, the environment can be beautified, wind prevention and sand fixation can be realized, and the method has wide feasibility.

Description

technical field [0001] The invention belongs to the field of ecological restoration, and in particular relates to a method for in-situ ecological restoration of steel slag hills based on discarded steel slag piles in the northern region. Background technique [0002] Steel slag is a typical industrial solid waste produced in the steelmaking process of iron and steel plants. The amount of steel slag produced is increasing rapidly with the rapid development of the iron and steel industry. Therefore, the treatment and resource utilization of waste slag in iron and steel enterprises are also receiving more and more attention. Although researchers have developed nearly 40 methods related to the comprehensive utilization of steel slag, so far no effective way of large-scale resource utilization of steel slag has been found. The current status of China's comprehensive utilization is far from the plan. The waste steel slag is in the state of stockpiling and landfill. The placed ste...
