Abstract

The invention provides a bioactive preparation. The bioactive preparation is prepared from the following components in parts by mass: 20 to 30 parts of biochar, 40 to 50 parts of medical stone, 10 to20 parts of humate and 5 to 10 parts of polyacrylamide. The preparation method of the bioactive preparation comprises the following steps: carrying out anoxic pyrolysis on household garbage in a pyrolysis furnace at 300-600 DEG C for 1-2 hours, crushing the obtained biochar, medical stone, humate and polyacrylamide to 200 meshes, uniformly mixing according to a ratio, adding 15-20% of water, and carrying out extrusion granulation to obtain the bioactive preparation. The bioactive preparation provided by the invention can reduce the heavy metal Cr (VI) water-soluble state, exchangeable state and carbonate binding state of calcareous soil, can increase the organic binding state and residue state, and promote the conversion of the heavy metal Cr (VI) from an effective state to a slow / delayedstate. Meanwhile, the granular structure is easy to use; compared with the prior art, the adsorbing and fixing effect on Cr (VI) is remarkable, and good application and popularization prospects are achieved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a biologically active preparation, and more specifically to the technical field of preparing a heavy metal Cr(VI) fixative suitable for calcareous soil with biological activity. Background technique [0002] As a persistent pollutant, heavy metals have been paid more and more attention to. Soil heavy metal pollution refers to the heavy metals brought into the soil due to human activities, resulting in the heavy metal content in the soil being significantly higher than the background content. In recent years, with the growth of people's awareness of environmental protection, the secondary pollution generated in the recycling process of electronic waste has received widespread attention, especially the heavy metal pollution and organic pollution in soil are worrying. Heavy metals in environmental pollution research mainly refer to elements with significant biological toxicity such as Pb,...
