Embodiment Construction

[0015] A method for purifying earthworms polluted by heavy metals, comprising a sugar bowl containing sugar and a direct current electric field, the specific implementation process of the method is as follows:

[0016] (a) dissolving potentially contaminated earthworms in sugar bowls;

[0017] (b) earthworms form earthworm slurry under the action of sugar;

[0018] (c) Putting salt water into the earthworm slurry to make an earthworm slurry solution;

[0019] (d) Using electrophoresis technology to place the earthworm slurry solution in a DC electric field, at this time the metal ions in the solution are positively charged;

[0020] (e) A negative electrode is probed into the earthworm slurry solution.

[0021] The metal ions move toward the negative electrode.

[0022] The method for purifying earthworms polluted by heavy metals of the present invention has the following beneficial effects: the method for purifying earthworms polluted by heavy metals of the present inventi...

Abstract

The invention discloses a method for purifying earthworms contaminated by heavy metal. The method involves a sugar tank containing sugar, and a direct-current electric field, and includes the specific implementation process that the earthworms possibly contaminated are put in the sugar tank to be mixed in the sugar; earthworm jelly is formed by the earthworms under the effect of the sugar; saline is put into the earthworm jelly to form an earthworm jelly solution; the earthworm jelly solution is placed in the direct-current electric field through the electrophoresis technology, and metal ions in the solution carry positive charges at the moment; and a negative electrode stretches into the earthworm jelly solution, the metal ions move towards the negative electrode at the moment, the heavy metal is thoroughly extracted out of the earthworm jelly based on the electroplating principle, and therefore the earthworm jelly can be used without worry.

Description

technical field [0001] The invention relates to a method for purifying earthworms polluted by heavy metals. Background technique [0002] Now the general wastes in urban and rural areas (domestic garbage, livestock manure, waste straw, urban sewage sludge, etc.) have become several major cancers in society. In the face of these major cancers, the most important treatment modes at present are composting, incineration and landfill. These treatment methods will not only produce secondary pollution, but the heavy metals accumulated in the waste cannot be properly disposed of. And because of the high reproduction rate and amazing food intake of earthworms, they also use organic humus as food, and after eating, they excrete vermicompost that is non-toxic, odorless, high-grade organic fertilizer rich in N, P, and K, and does not produce secondary fertilizers. pollute. In addition, earthworms also have the unique ability to adsorb heavy metals, so it is imperative to use earthwor...
