Problems solved by technology

However, these sewage ponds are treated according to the existing facilities, which is costly and requires the construction of a large amount of infrastructure to complete
[0004] At the same time, during the deposition of manure, a large amount of body hair of cattle will be deposited at the bottom of the water. If it is not treated, the mud contaminated by cow manure will not be usable.

Embodiment example 1

[0015] 1. For the sewage pond polluted by cow manure for more than five years but less than ten years, about ten cattle are excreted in this sewage pond every year.

[0016] (1) Preparation of fermented yeast liquid

[0017] Add 150g of salt, 100g of glucose, and 5kg of corn flour into a glass jar in sequence. After fully stirring, add 100kg of water and stir fully again, then add 250g of starter, and then seal the glass jar.

[0018] (2), preparation of fermentation broth

[0019] The above fermented yeast liquid is placed in an environment with a temperature of 25° C. for 5 days to obtain a fermentation liquid.

[0020] (3) Sprinkle the fermented liquid evenly into the sewage pond containing cow dung according to 0.2 kg of fermented liquid per cubic meter of water area.

[0021] (4), once every half month. After four treatments, just go with one treatment per month.

[0022] The water quality was tested and the following results were obtained

Abstract

The invention belongs to a sewage treatment method, in particular to a treatment method for a small sewage pond containing cow dung. By using 100kg of water, 100-200g of salt, 100g of glucose, and 5kg of corn flour to make a biological fermentation yeast liquid, add 150-250g of starter to the yeast liquid, obtain a fermentation liquid by fermentation, and sprinkle the fermentation liquid on the manure in the sewage pond. The sewage treated by the above basically achieves no Escherichia coli, no sulfide, and no ammonia gas.

Description

technical field [0001] The invention belongs to a sewage treatment method, in particular to a treatment method for a small sewage pond containing cow dung. Background technique [0002] Now in general large-scale cattle farms, the methods of manure treatment are as follows: 1. The cow manure is anaerobically fermented to produce biogas, which is used for cooking, boiling water, cooking, heating, lighting, and biogas residues are applied to farmland or water nearby. In this treatment method, although the cow dung has been technically treated, the biogas slurry and cow urine are directly discharged, causing pollution, and the biogas residue has not been made into commercial fertilizer, so it can only be applied to the nearby farmland or The use of ponds is limited, and when the biogas production is greater than the use, it is discharged into the atmosphere, resulting in secondary pollution. In addition, when the amount of cow dung is large, the investment is also large; Oxyge...
