A kind of manufacturing device and method of ecological nutritional blanket base for breeding

Abstract

The invention discloses a preparation device for a breeding eco-nutritional blanket medium. The preparation device comprises a deodorization and sterilization tank, a mixing agitator, a regulating tank, a slurry homogenizing box, a dewatering device, a simple presser, a drying device and a cutting device, wherein the deodorization and sterilization tank, the mixing agitator, the regulating tank and the slurry homogenizing box are connected through slurry delivery pumps and pipelines in sequence; the dewatering device is arranged at the discharge opening of the slurry homogenizing box; the simple presser is arranged at the discharge opening of the dewatering device; the drying device is arranged at the discharge opening of the simple presser; and the cutting device is arranged at the discharge opening of the drying device. The invention further provides a preparation method for the breeding eco-nutritional blanket medium. According to the invention, resource regeneration and efficient utilization of industrial sludge, domestic sludge and agricultural waste are realized, the produced breeding eco-nutritional blanket medium can avoid soil impoverishment, and a novel ecological breeding nutritional medium with a low production cost is provided.

Description

technical field [0001] The patent of the invention relates to a new type of ecological material for agriculture, forestry and horticulture breeding. It is a kind of high-efficiency, ecological and environment-friendly medium material produced by using various industrial or domestic sludge as the basic material, and belongs to the new technology of solid waste regeneration and ecological restoration. Background technique [0002] With the rapid development of industry and the increase of urban scale, the amount of industrial sludge and urban sludge is increasing. At present, most of the methods to solve this problem are simple burial or burning, but due to the existence of industrial sludge A large amount of toxic heavy metal elements, urban sludge is prone to irritating odor due to the high content of organic matter, traditional burial methods or burning methods cannot completely solve these pollution problems, and the cost of treatment is relatively high.

Problems solved by technology

[0002] With the rapid development of industry and the increase of urban scale, the amount of industrial sludge and urban sludge is increasing. At present, most of the methods to solve this problem are simple burial or burning, but due to the existence of industrial sludge A large number of toxic heavy metal elements, urban sludge is prone to irritating odor due to the high content of organic matter, the traditional landfill method or burning method can not completely solve these pollution problems, and the cost of treatment is relatively high

[0003] Traditional agricultural garden breeding, especially the nutrient base of greening turf, generally uses organic fertilizers added to the soil. After the seeds develop into seedlings, the plants and the lower nutrient base are generally removed together when transplanting, which will cause the nutrient-rich surface of the land to become nutrient-rich. Erosion and land impoverishment

[0004] Therefore, the current status quo is that on the one hand, a large amount of toxic and polluting industrial sludge and urban sludge are produced in large quantities and cannot be effectively treated; drain
