Embodiment 1

[0025] Embodiment 1. Preparation of organic compost

[0026] (1) Prepare raw materials according to the following weight ratio: 35 parts of cassava residue, 10 parts of plant ash, 20 parts of chicken manure, 20 parts of cow dung, 3 parts of EM bacteria liquid (5-1 billion active bacteria per ml), 12 parts of water parts, cellulase (500,000 units per gram) 0.0002 parts.

[0027](2) Fermentation preparation method: evenly disperse the cassava residue in the fermentation tank (the area of ​​the fermentation tank is determined according to the daily output of the equipment, and the amount of fermentation materials in each fermentation tank is not less than the amount of production materials for one day), and then Evenly disperse the plant ash on the cassava dregs, turn it over 3-4 times with a compost turner, mix the cassava dregs and the plant ash evenly; then evenly disperse the chicken manure and cow dung on the mixture of the cassava dregs and the plant ash; At the same time,...

Embodiment 2

[0028] Embodiment 2. a kind of composite soil remediation agent containing microbial bacterium, comprises the component of following parts by weight:

[0029] 1 part of Bacillus Pasteur spore powder, 30 parts of phosphogypsum powder, 40 parts of organic compost, 20 parts of grass charcoal powder, 4 parts of potassium fulvic acid powder, 0.5 part of powdery bacterial powder carrier, 0.5 part of glycerin, and appropriate amount of water vapor.

[0030] combined with figure 1 Illustrate the preparation method of soil remediation agent of the present invention:

[0031] Add phosphogypsum powder, organic compost, peat powder, and potassium fulvic acid powder into the mixer 1 according to the above weight ratio and mix evenly, then send them into the disc or drum granulator, and add water vapor to granulate, The amount of steam to be added is moderate when the water content of the granules coming out of the granulator is 40%-50%. The tail temperature is not lower than 60°C), the d...

Abstract

The invention relates to a compound soil remediation agent containing microorganism bacteria and a preparation method thereof. The remediation agent comprises the following components in parts by weight: 0.01-3 parts of bacillus pasteurii spore powder, 5-50 parts of phosphogypsum powder, 10-60 parts of organic compost, 5-50 parts of turf powder, 1.5-5 parts of potassium fulvate powder, 0.2-0.5 part of powdery bacteria powder carriers and 0.15-1 part of glycerin. The remediation agent has round and smooth grains and high grain hardness, is harmless to seeds, can serve as a base fertilizer together with other fertilizers, can be sown together with seeds, integrates multiple remediation functions including organic complexation and passivation remediation, inorganic passivation remediation, microorganism passivation remediation and the like, has a comprehensive and strong soil remediation function, and can stimulate growth and reproduction of arbuscular mycorrhizal fungi at the roots of crops, accelerate heavy metal passivation, stimulate crop growth and enhance the immunities of crops.

Description

technical field [0001] The invention relates to a soil remediation agent and a preparation method thereof, in particular to a compound soil remediation agent containing microbial bacteria capable of passivating heavy metals and a preparation method thereof, belonging to the field of biochemical industry. Background technique [0002] In recent years, my country's industry has developed rapidly. At the same time, the large-scale discharge of industrial waste has caused changes in the physical and chemical properties of heavy metal content in large areas of land. The Ministry of Environmental Protection and the Ministry of Land and Resources jointly issued the "National Soil Pollution Survey Bulletin" not long ago. , the results show that the total exceeding rate of national soil is 16.1%, of which the proportions of slightly, lightly, moderately and heavily polluted sites are 11.2%, 2.3%, 1.5% and 1.1% respectively. Inorganic pollutants are the main type of pollution, followed...
