Problems solved by technology

However, there are two problems with the liquid: one is that the liquid is highly anoxic; the other is that a series of organic substances (such as quinones) that cannot be decomposed by anaerobic bacteria are left in the liquid
This method not only requires a large investment in infrastructure, but also takes up a lot of land, consumes a lot of energy, and has no benefits.

Embodiment 1

[0037] A method for treating biogas slurry and dung water, specifically:

[0038]Step 1: Build 4 decomposition tanks after the biogas tank or septic tank. The volume of each decomposition tank is the volume of biogas slurry or manure discharged in three days, and add organic carbon to the biogas tank or septic tank Bacterial liquid, the biogas slurry or dung in the biogas tank or septic tank is discharged into the decomposition tank through the pipeline respectively, and the organic carbon bacterial liquid flows into the decomposition tank together with the biogas slurry or dung, in terms of volume, the The amount of organic carbon bacteria liquid added is 0.2% of the amount of biogas slurry or dung water, decomposed for 10-12 days, so that the organic matter in biogas slurry or dung water is converted into small molecule water-soluble organic carbon, and organic carbon water fertilizer is obtained; the organic carbon bacteria liquid Effective carbon content ≥ 130 g / L, functio...

Abstract

The invention discloses a biogas slurry and liquid dung treatment method which comprises the following steps: 1, decomposing, namely adding an organic carbon bacterium liquid into biogas slurry or liquid dung, so that organic matters in the biogas slurry or liquid dung are transformed into small-molecule water-soluble organic carbon, thereby obtaining an organic carbon water fertilizer, wherein the content of organic carbon nutrients in the organic carbon bacterium liquid is more than or equal to 12.5%, the content of the water-soluble organic matters is more than or equal to 25%, and the living bacteria count is more than or equal to 200 million / mL; and 2, discharging the organic carbon water fertilizer into a circular trench, planting submerged plants in the circular trench, and planting fungi on ridges on two sides of the circular trench. According to the method disclosed by the invention, the biogas slurry and liquid dung can be transformed and utilized in situ, so that circular economy is pushed, and a good ecological environment is promoted; and moreover, the organic carbon water fertilizer is used for plant cultivation, the dosage of chemical fertilizers and pesticides is reduced, and modernized agriculture shakes out shadow of chemical agriculture.

Description

technical field [0001] The invention relates to the technical field of environmental protection biological treatment, in particular to a method for treating biogas slurry and dung water. Background technique [0002] Biogas slurry and septic tanks decompose organic matter in a solid-liquid mixed state. This treatment causes a large amount of organic matter to be decomposed from macromolecules into macromolecular groups, and then partially decomposed into small molecules that are dissolved or suspended in the liquid. From the appearance Watch it change from solid to liquid. In this process, small organic molecules are partially decomposed into methane and carbon monoxide, and this mixed gas is biogas. However, there are two problems in the liquid: one is that the liquid is highly anoxic; the other is that a series of organic substances (such as quinones) that cannot be decomposed by anaerobic bacteria remain in the liquid. Dilute the untreated biogas slurry or manure with w...
