Original ecological treatment method and device for cattle manure in cattle farm

Abstract

The invention belongs to the technical field of domestic animal manure treatment and relates to a cattle farm cattle manure originally ecological treatment method and device. The treatment method comprises that 1), a manure storage tank 1, a manure storage tank 2, a filtered water storage tank, an oxidation pond and a fermented manure stacking place are built, 2), manure and washing water from a cattle farm are discharged into the manure storage tank 1, when the manure water in the manure storage tank 1 overflows from a manure water discharge outlet, the overflowing manure water flows into the manure storage tank 2, and the fixed manure is subjected to stacking natural fermentation in the manure storage tank 1, 3), after the manure water is subjected to natural sedimentation in the manure storage tank 2, and the treated manure water is discharged into the filtered water storage tank by a siphon and crops are irrigated with the filtered water in the filtered water storage tank, or the filtered water is discharged into the oxidation pond, is subjected to full oxidation and then is used for crop irrigation, and 4), the manure suspending in the upper layer of the materials in the manure storage tank 1 and the manure storage tank 2 is excavated by a manure excavator, then is fed into the fermented manure stacking place and then is stacked so that cattle farm cattle manure treatment is finished. The treatment method has the advantages of simple treatment processes and low treatment cost.

Description

technical field [0001] The invention belongs to the technical field of livestock manure treatment, in particular to an original ecological treatment method and device for cow manure in large-scale cattle farms. technical background [0002] Cow manure treatment is one of the worldwide problems. Cow dung is not only sticky and difficult to handle but also has low use value, and its pollution is very serious at the same time. Foreign countries have invested a lot of money to solve the cow dung problem. The way to deal with cow dung in Switzerland is to decompose it to generate biogas for power generation, which requires a huge investment and high technological content. The Japanese method of treating cow dung is to ferment cow dung to produce biogas, extract hydrogen and generate electricity, and the cost of this method is also high. In addition, there is also a method for producing bio-fertilizer using cow dung as a raw material, but the fermentation time is long, the ener...
