Problems solved by technology

[0002] A large amount of silt is often produced during the construction of lake bottom and river tunnels. In the face of such a large amount of silt, the traditional treatment method often adopts simple stacking and natural drying. On the one hand, it requires a large amount of land for silt stacking and natural drying. It usually lasts 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 the lake bottom dredging. Problems faced in engineering

Abstract

The invention provides a planting soil prepared by solidifying silt and its application. The planting soil is made of the following raw materials in parts by weight: 70-85 parts of silt, 5-12 parts of silt curing agent, lignin sulfonate 1‑3 parts, 2‑5 parts of potassium chloride, 3‑10 parts of plant ash, 2‑6 parts of calcium magnesium phosphate fertilizer, 1‑4 parts of ammonium bicarbonate. The planting soil prepared by solidifying silt in the present invention is applied to planting vegetation. The planting soil of the invention conforms to the nutrient absorption and vegetation growth law at the initial stage of planting, significantly improves the growth of plants planted in the soil after the sludge is solidified, has good treatment effect, protects the environment, and regenerates and utilizes resources.

Description

technical field [0001] The invention relates to the field of sludge treatment and its application, in particular to planting soil prepared by solidifying sludge and its application. Background technique [0002] A large amount of silt is often produced during the construction of lake bottom and river tunnels. In the face of such a large amount of silt, the traditional treatment method often adopts simple stacking and natural drying. On the one hand, it requires a large amount of land for silt stacking and natural drying. It usually lasts 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 the lake bottom dredging. problems in engineering. There are many methods of sludge treatment, such as composting and fermenting sludge to make organic fertilizer, but due t...
