Embodiment Construction

[0023] 1. Preparation of litter biochar:

[0024] The litter is a mixture of rice husk, sawdust, bark and sawdust, distiller's grains, crushed straw, etc. After being used in a pig house, it is air-dried and then ground, and the granules passed through a 60-mesh sieve are obtained as Fermented mattress material, set aside.

[0025] Put the fermentation mattress material into a 25mL small crucible, compact it, cover the small crucible, then put the small crucible into a 50mL large crucible, and then cover the large crucible with a lid.

[0026] Put the large crucible into the muffle furnace, raise the temperature to 300°C at a rate of 5°C / min, then burn at a constant temperature for 6 hours, and take it out after cooling to room temperature to obtain litter biochar (D300) at 300°C.

[0027] According to the above steps, litter biochars (D400 and D500) at 400 °C and 500 °C were prepared by burning at constant temperatures of 400 °C and 500 °C, respectively.

Abstract

Charcoal preparation method based on mattress fermented feed and application thereof belong to the field of environmental restoration technologies. The mattress fermented feed is grinded after air drying, to obtain a raw material with the diameter of 60 meshes. The raw material is sealed in a crucible, the crucible is put in a muffle furnace, and after calcination of 300 to 500 DEG C and cool to ambient temperature, bedding biochar inside the crucible is taken out. Advantages of the invention lie in that: materials are easy to get, costs are low, a preparation process is simple, and an effect of processing heavy metal pollutants in waste water is obvious. Further, organic wastes such as waste padding are also recycled.

Description

technical field [0001] The invention belongs to the technical field of environmental restoration, and in particular relates to a preparation method of a material capable of removing heavy metal pollutants in water bodies and soil environments. Background technique [0002] With the increasing development of industry, the amount of heavy metals contained in sewage is also increasing day by day. And when heavy metals in sewage seep into the earth, and industrial and mining solid waste pollution, etc., the heavy metals in the soil can no longer be ignored. Therefore, how to remove heavy metal pollutants in water and soil environment has become an urgent scientific problem to be solved. [0003] At present, there are usually two methods for the treatment of heavy metals in sewage. One is to transform the dissolved heavy metals in the sewage into insoluble heavy metal compounds or elements, which are removed from the waste water by precipitation and flotation. Neutralization and...
