Embodiment 1

[0017] Example 1: A preparation method of soilless spray coating additives for covering materials, crushing 60 parts of reverse flotation phosphorus tailings into crushed stones with a diameter of 5-20 cm, and placing the crushed phosphorus tailings at 900-1000 °C Calcined for 1.5~2h, crushed again into particles with a particle size of 10~20 mesh, prepared pulp sludge: pine leaves: garden soil according to the ratio of 1:1:4 to make humus soil, and the calcined and crushed reverse flotation phosphorus The tailings were mixed with 20 parts of humus and 20 parts of cement.

Embodiment 2

[0018] Example 2: A preparation method of soilless spray coating additives for covering materials, crushing 60 parts of reverse flotation phosphorus tailings into crushed stones with a diameter of 5-20 cm, and placing the crushed phosphorus tailings at 900-1000 °C Calcined for 1.5~2h, crushed again into particles with a particle size of 10~20 mesh, prepared pulp sludge: pine leaves: garden soil according to the ratio of 1:1:4 to make humus soil, and the calcined and crushed reverse flotation phosphorus The tailings were mixed with 20 parts of humus and 30 parts of cement.

Embodiment 3

[0019] Example 3: A preparation method of soilless spray coating additives for covering materials, crushing 60 parts of reverse flotation phosphorus tailings into crushed stones with a diameter of 5-20 cm, and placing the crushed phosphorus tailings at 900-1000 °C Calcined for 1.5~2h, crushed again into particles with a particle size of 10~20 mesh, prepared pulp sludge: pine leaves: garden soil according to the ratio of 1:1:4 to make humus soil, and the calcined and crushed reverse flotation phosphorus The tailings were mixed with 30 parts of humus and 20 parts of cement.

Abstract

The invention discloses an additive of a soilless spraying covering material and a preparation method of the additive and belongs to the technical field of refuse landfill treatment. The additive is prepared from, by weight, 50-60 parts of phosphate tailings, 20-30 parts of humus and 20-30 parts of cement. The reverse flotation phosphate tailings are smashed into gravel with the diameter ranging from 5 cm to 20 cm, the gravel is put at the temperature of 900-1,000 DEG C and calcined for 1.5-2 h, the gravel is smashed into particles with the grain diameter ranging from 10 mesh to 20 mesh again, the particles are mixed with the humus and the cement in proportion, and the additive of the soilless spraying covering material can be obtained. According to the additive of the soilless spraying covering material, the reverse flotation phosphate tailings can be massively utilized, effective phosphorus is enriched through the humus and the cement, the alkalinity of the additive is reduced, and the use effect of the covering material is guaranteed.

Description

technical field [0001] The invention relates to the technical field of garbage landfill treatment, in particular to an additive for soilless spray coating covering materials and a preparation method thereof. Background technique [0002] While the economy continues to grow at a high speed, the living standard improves rapidly, and the urbanization process continues to accelerate, the output of urban domestic waste in my country is also increasing day by day. The harmful components contained and produced in garbage will pollute the atmosphere, soil, and water, which not only seriously affects the quality of the urban environment, but also directly threatens human health, becoming one of the social hazards. Therefore, the disposal of municipal solid waste has become a major environmental problem to be solved urgently. Municipal waste landfill is the most basic disposal method of municipal waste. Generally, urban waste is sorted and recycled, and then the non-recyclable garba...
