Embodiment 1

[0024] The embodiment of the present invention provides a production method of barium salt scallop shell powder used for soil restoration and fertilization, which relies on reaction equipment, and the reaction equipment includes a first measuring hopper 1, a first screw conveyor 2, Washing machine 3, second measuring bucket 4, second screw conveyor 5, first belt conveyor 6, dryer 7, second belt conveyor 8, third measuring bucket 9, third screw conveyor 10 , heating machine 11, fourth screw conveyor 12, third belt conveyor 13 and dust collection chamber 14, sixth screw conveyor 20, box conveyor 21 and product hopper 22;

[0025] The discharge port of the first measuring hopper 1 is set correspondingly to the feeding place of the first screw conveyor 2, and the discharge place of the first screw conveyor 2 is set correspondingly to the feeding port of the washing machine 3 , the discharge port of the cleaning machine 3 is set correspondingly to the feed port of the second measur...

Embodiment 2

[0035] The reaction equipment that embodiment 2 relies on is the same as embodiment 1, and embodiment 2 is the same as step 1) and step 2) of embodiment 1, the difference is that in step 3), the semi-finished scallop shell of storage is passed by the third screw The conveyor 10 transports the scallop shells to the heating machine 11, calcining and heating the scallop shells at 700° C., and the calcined and heated scallop shells are left for 6 hours to cool down to room temperature.

[0036] The content of alkali in the shell powder produced in Example 2 is 52%, the content of calcium acidified is 88%, and the pH value is 8.

Embodiment 3

[0038] The reaction equipment that embodiment 3 relies on is the same as embodiment 1, and embodiment 3 is the same as step 1) and step 2) of embodiment 1, the difference is that in step 3), the semi-finished scallop shell of storage is passed by the third spiral The conveyor 10 transports the scallop shells to the heating machine 11 , calcines and heats the scallop shells at 900° C., and leaves the calcined and heated scallop shells for 12 hours to cool down to normal temperature.

[0039] The content of alkali in the shell powder produced in Example 3 is 55%, the content of calcium acidified is 95%, and the pH value is 10.

[0040] The barium salt scallop shell powder for soil remediation and fertilization prepared by the above-mentioned embodiment 1, embodiment 2 and embodiment 3 of the present invention has the following advantages:

[0041] The shell powder produced by the invention is mixed with soil, which can seal the heavy metals in the soil, neutralize the acidity an...

Abstract

The invention discloses a barium salt technology for soil restoration and fertilization, and relates to the field of soil restoration and soil improvement technology. The invention has a simple production process, and does not destroy the molecular structure of calcium by calcining natural shells at a special temperature. By mixing a certain amount of scallop shell powder into the soil, the heavy metals in the soil are sealed, and the acidity and alkalinity of the soil are neutralized, so that the soil can effectively absorb the rich trace elements and good minerals in the scallop shell powder, soften the soil, Make crops no longer absorb harmful heavy metals, which is conducive to better growth of crops, and achieves soil restoration and improvement effects.

Description

technical field [0001] The invention relates to the technical field of soil remediation and soil improvement, in particular to a production method of barium salt scallop shell powder used for soil remediation and fertilization. Background technique [0002] In order to ensure food self-sufficiency, our country must have a large amount of arable land as a guarantee. With the development of our country's industrialization, we have paid a large price for resources and the environment. The ensuing environmental and soil pollution problems have raised the issue of food security and ecological environment protection. It warns that the ecological environment has become a shortcoming in building a well-off society in an all-round way, which has attracted widespread attention worldwide. [0003] As development enters the new normal, a good ecological environment has increasingly become a scarce resource. 16% of the country's soil is polluted by harmful substances exceeding the permi...
