Abstract

The invention discloses a planting soil made through solidification of sludge, a preparation method thereof and application thereof. The planting soil comprises following components: lake bed sludge containing 55 to 60 % of water, a water and soil solidification agent which is 4 wt% of the sludge, and an organic fertilizer which is 1 wt% of the sludge. The preparation method of the planting soil made through solidification of the sludge comprises the following steps of exhausting flowing water for desilting a lake bed and generating sludge, adding the soil solidification agent in the sludge according to a formula, stirring to a uniform state, standing for 5 to 10 days, solidifying, smashing after solidification and mixing, adding the commercial organic fertilizer according to a formula, and mixing to obtain the planting soil made through solidification of sludge. The planting soil made through solidification of the sludge can be applied to plantation of vegetation. The planting soil accords with rules of nutrient absorption in the initial stage of the plantation of vegetation, and growth of the vegetation, and growth conditions of plants growing in the planting soil made through solidification of the sludge can be distinctly improved, the treatment is good in effect, environment can be protected, and resources can be recycled.

Description

technical field

[0001] The invention relates to a technique for converting silt solidification into planting soil, in particular to a planting soil prepared by silt solidification, a preparation method and application thereof. Background technique

[0002] A large amount of lake bottom silt is often produced during the construction of the lake bottom tunnel. In the face of such a large amount of silt, the traditional treatment method often adopts simple stacking and natural drying. Lasting for a long time, in the case of limited urban land area, it often causes a lot of waste of resources. On the other hand, the stacking process may also cause secondary pollution to the stacking area. Therefore, finding a reasonable sludge treatment method has always been a lake bottom dredging project. problems faced. There are many methods of sludge treatment, such as composting and fermenting sludge to make organic fertilizer, but due to relatively high production costs, this method of o...
