Embodiment 1

[0029] The present invention provides a method of repairing a hemp pool core repair agent for heavy metal contaminated soil, which includes the following steps:

[0030]Step 1. Preparation of Hanji Biocarbon Bio-Carbon Base Soil Repair: Collect the Henna Bell Core, will be pulverized by the collected Henasonic rod core, put the halve rod core in the pulverizer to smash, crushing the hemp The particle size of the roller is controlled between 32 mm, then the pulverized Henna rod is high-temperature carbonization, and the pulverized Henna rod core is placed in a high temperature oven, and the temperature is controlled at 180 ° C, and the time is controlled at 60 min. It is then taken out to make bio-activated carbon, and then bio-activated carbon is further pulverized, and bio-activated carbon is placed in a pulverizer for pulverization, and the particle size of bio-activated carbon is controlled between 10 mm, and 1000 parts of biological Activated carbon, add 2000 copies of pure wa...

Embodiment 2

[0041] The present invention provides a method of repairing a hemp pool core repair agent for heavy metal contaminated soil, which includes the following steps:

[0042] Step 1. Preparation of Hanji Biocarbon Bio-Carbon Base Soil Repair: Collect the Henna Bell Core, will be pulverized by the collected Henasonic rod core, put the halve rod core in the pulverizer to smash, crushing the hemp The particle size of the roller is controlled between 34 mm, then the pulverized hemp rod core is high-temperature carbonization, and the pulverized Henna rod core is placed in a high temperature oven, and the temperature is controlled at 200 ° C, and the time is controlled at 65 min. It was then taken out, and the biologically activated carbon was produced, and then bio-activated carbon was further pulverized, and the bio-activated carbon was placed in a pulverizer and pulverized, and the particle size of the bio-activated carbon was controlled between 11 mm, and 1000 parts of the biological Act...

Embodiment 3

[0053] The present invention provides a method of repairing a hemp pool core repair agent for heavy metal contaminated soil, which includes the following steps:

[0054] Step 1. Preparation of Hanji Biocarbon Bio-Carbon Base Soil Repair: Collect the Henna Bell Core, will be pulverized by the collected Henasonic rod core, put the halve rod core in the pulverizer to smash, crushing the hemp The particle size of the roller is controlled between 36 mm, and then the pulverized Henna rod is high-temperature carbonization, and the pulverized Henna rod core is placed in a high temperature oven, and the temperature is controlled at 220 ° C, and the time is controlled at 70 min. It was then removed, and the biologically activated carbon was produced, and then bio-activated carbon was further pulverized, and the bio-activated carbon was placed in a pulverizer and pulverized, and the particle size of the bio-activated carbon was controlled between 12 mm, and 1000 parts of the biological Activ...

Abstract

The invention discloses a hemp stem core repairing agent repairing method for heavy metal contaminated soil, and particularly relates to the technical field of contaminated soil remediation methods, the method specifically comprises the following steps: step 1, preparing a hemp stem core biochar-based soil repairing agent: collecting hemp stem cores, crushing the collected hemp stem cores, putting the hemp stem core into a crusher for crushing. The hemp stem core is used as a main raw material of the repairing agent, hemp stem core biochar is applied to improvement and treatment of polluted soil, the special hemp stem core biochar-based soil repairing agent applied to treatment of the polluted soil is formed, the problem of heavy metal pollution of the soil can be well solved, the hemp stem core is turned into wealth from waste, and the soil repairing agent is environmentally friendly. The treatment cost of the heavy metal contaminated soil is reduced, waste resources are reasonably utilized, the environment is protected, and the method conforms to the law of ecological sustainable development.

Description

Technical field [0001] The present invention relates to the technical findings of contaminated soil repair methods, and more particularly, the present invention relates to a repair method for the repairing method for the repair of heavy metal contaminated soil. Background technique [0002] At present, with the rapid development of urbanization, a large number of people are active, such as chemical enterprises produce sewage, sewage emissions, producing a large amount of pollutants into the soil and accumulate to a certain extent, causing soil pollution, soil quality deterioration, and others or others Biological hazards, soil pollution from the type of contamination, including inorganic contaminants caused by heavy metals such as mercury, cadmium, lead, arsenic, and various chemical pesticides, oil and their lysis products or other organic synthetic products Organic Pollutants. From the perspective of pollution, various types of domestic sewage and industrial wastewater are emis...
