Problems solved by technology

In addition, some biological waste, livestock and poultry manure and other sundries will be mixed in the vermicompost, and some odor will remain to some extent, which is difficult to completely remove. Various reasons cause some earthworm larvae to die, and those dead earthworm larvae are mixed in debris and will also produce odor. This is also a serious problem faced by vermicompost as a deodorant. Countries have not yet found a fundamental solution. Solution

Abstract

The invention relates to the technical field of the preparation of novel environment-friendly absorbing agents, and in particular relates to a method for preparing vermicompost activated carbon by utilizing vermicompost. The method comprises the following steps of: airing and drying vermicompost; then crashing, grinding and screening; then immersing by a composite activated agent water solution; then filtering; putting a solid obtained through filtering into an activating oven; heating, preserving the temperature and activating, and then taking out; then immersing by diluted hydrochloric acid; then filtering; washing a filtered cake in an ultrasonic reactor, and then rinsing by deionized water to be neutral; and then drying, crashing and screening, thereby obtaining the vermicompost activated carbon. The vermicompost activated carbon prepared by the method provided by the invention has high absorption capability, has high particle intensity, has a good effect for removing pollutants, is a favorable absorbing agent and a favorable deordorant, and has favorable absorption effect for waste water, heavy metal and foul gases. The method for preparing vermicompost activated carbon by utilizing vermicompost provided by the invention has dual beneficial effects of environment friendliness and economy.

Description

technical field [0001] The invention relates to the technical field of preparation of novel environmentally friendly adsorbents, in particular to a method for preparing vermicompost activated carbon by utilizing vermicompost. Background technique [0002] Earthworms are commonly known as "earth dragons" in my country, and earthworms play an important role in the decomposition of organic matter and the release of soil nutrients. Earthworms have a strong digestive ability, and their digestive tract can secrete protease, lipase, cellulase, chitinase and amylase, etc. Under the action of these enzymes and microorganisms, organic substances will be hydrolyzed into simple carbohydrates, These substances combine with minerals in the soil to form a highly integrated organic-inorganic complex, which is finally discharged in the form of vermicompost. Earthworms eat a lot, and 100 million earthworms can swallow 40-50 tons of garbage a day and discharge about 20 tons of vermicompost. ...
