Embodiment Construction

[0039] Below in conjunction with embodiment the present invention will be further described:

[0040] 1. The method of using lake silt to produce ecological and environmentally friendly nutrient soil: add the ingredients of ecological and environmentally friendly nutrient soil to a twin-shaft mixer for mixing, and then transport it to the roller machine through a belt conveyor to squeeze into irregular particles after mixing evenly. The irregular particles are then input into the integrated soil sterilization and insecticide device for sterilization and drying. The irregular particles after sterilization and drying are the finished products of ecological and environmental protection nutrient soil. The mass fraction of water is ≤30%.

[0041] The ingredients of the ecological environment-friendly nutrient soil are composed of the following components by weight percentage: 72% of semi-finished products of ecological environment-friendly nutrient soil, 12% of fermented livestock ...

Abstract

The invention discloses a method for producing ecological environment-friendly nutrition soil by using lake sludge. The key point of the technical scheme is that the method comprises the following steps of: adding materials into a double-shaft mixer and stirring, after uniformly stirring, conveying to a roller machine, extruding into irregular particles, killing bacteria and insects, and drying to obtain an ecological environment-friendly nutrition soil finished product. The method has the characteristics of simplicity, high production efficiency and low cost; the lake sludge with high water content is not needed to be dehydrated; and the ecological environment-friendly nutrition soil of various formulas can be processed in the dredging fields of ports, channels, lakes and rivers, and a large amount of soil resources are saved. The ecological environment-friendly nutrition soil is complete in nutrition component, high in fertilizer efficiency, durable in water retention capacity, and is non-toxic, innocent and odourless, and can provide nutrient elements which are required by growth of plant, and reduce the damage of pathogenic bacteria and pests to plant. The method is suitable for producing the ecological environment-friendly nutrition soil of various formulas by using lake sludge as a main raw material.

Description

technical field [0001] The invention relates to the soil field, in particular to a method for producing eco-environmental protection nutrient soil by using lake silt. Background technique [0002] In order to improve the water quality of rivers and lakes, ensure the normal flood discharge capacity of rivers and the smooth flow of waterways and ports, my country has carried out large-scale dredging and dredging projects. The amount of dredged silt in the delta is about 80 million cubic meters. In the next ten years, dredging and dredging projects in water conservancy, rivers, lakes and ports will still produce a large amount of dredged silt, which has become an unavoidable reality. [0003] The dredged silt produced in the dredging project is usually disposed of by stacking or discarding. On the one hand, it not only causes a lot of waste of land resources, but also causes irreparable damage to the ecological environment. On the other hand, most of the dredged silt contains he...
