Embodiment Construction

[0060] Below in conjunction with embodiment the present invention will be further described:

[0061] 1. The production method of diatomite compressed nutrient soil: (1) Input the ingredients of diatomite compressed nutrient soil into the running mixer and stir, and after stirring evenly, input it into the tablet press to compress into diatomite compressed nutrient soil flakes, silicon The thickness of the diatomaceous earth compressed nutrient soil sheet is controlled at 26mm; (2) The diatomite compressed nutrient soil sheet is transported to a microwave belt type drying and sterilizing machine for low-temperature sterilization and drying, and the temperature is controlled at 70-90°C , the time is controlled at 50 minutes, the water content of the sterilized and dried diatomite compressed nutrient soil sheet is ≤14%; (3) the sterilized and dried diatomite compressed nutrient soil sheet is transported to the heat preservation extinguisher In the bacterial bank, use the residua...

Abstract

The invention discloses a method for producing diatomite compressed nutrient soil. According to key points of the technical scheme, the method comprises the following steps: acidizing diatomite and sludge, stirring, compressing and performing low-temperature microwave sterilization on ingredients of the diatomite compressed nutrient soil, and packaging to obtain the finished product. The diatomite compressed nutrient soil consists of acidized diatomite, acidized sludge, instant sodium silicate, polyvinyl alcohol, ferrous sulfate, peat, flower ceramsite, high viscosity attapulgite clay, biogas slurry, biogas residue, crushed plant fibers, expanded vermiculite, expanded perlite, super absorbent resin and other materials. The diatomite compressed nutrient soil contains lots of nitrogen, phosphorus, potassium, organic matters and multiple trace elements, can provide necessary nutrient elements for plant growth and reduce harm of pathogenic bacteria and injurious insects to plants and contributes to normal plant growth and development, the ecological environment is protected, and the method for producing the diatomite compressed nutrient soil is suitable for producing diatomite compressed nutrient soil of different formulas.

Description

technical field [0001] The invention relates to nutrient soil, in particular to a production method of diatomite compressed nutrient soil. Background technique [0002] Diatomaceous earth is a kind of biogenic siliceous sedimentary rock, which is mainly composed of the remains of ancient diatoms. Since the formation of diatomite ore has gone through a long geological age, in addition to containing a large number of diatoms, it also contains many impurities Among them, quartz, hydromica, kaolinite, montmorillonite, iron minerals, carbonates, sulfates, volcanic ash and other mineral debris are common. [0003] Sludge is a kind of easily corrupt and smelly paste produced in the process of sewage treatment. It enriches the pollutants in sewage, contains a large amount of nutrients such as nitrogen and phosphorus, organic matter, virus microorganisms, parasite eggs, heavy metals, etc. Toxic and harmful substances will cause serious harm to the environment if they are not effecti...
