Mobile biogas slurry concentration integrated equipment

Abstract

The invention discloses movable type biogas slurry concentrating integrated equipment. The movable type biogas slurry concentrating integrated equipment comprises a container, a biogas slurry storage pool, a sand filtering tank, a core type filter and a disc-tube type reverse osmosis membrane concentration device, wherein an operation space is defined in the container; the biogas slurry storage pool is arranged in the operation space and is used for storing biogas slurry to be treated; the sand filtering tank is arranged in the operation space, is connected with the biogas slurry storage pool and is used for carrying out primary filtering on the biogas slurry to be treated; the core type filter is arranged in the operation space, is connected with the sand filtering tank and is used for carrying out secondary filtering on the biogas slurry subjected to primary filtering; the disc-tube type reverse osmosis membrane concentration device is arranged in the operation space, is connected with the core type filter and is used for concentrating the biogas slurry subjected to secondary filtering so as to obtain concentrated biogas slurry and penetrating fluid. According to the movable type biogas slurry concentrating integrated equipment disclosed by the invention, the structure is simple, the operation is stable, the biogas slurry utilization rate is high, the operation and the management are easy, the operation is convenient, the expandability is achieved, and volume reduction of the biogas slurry and concentration of nutrient substances can be realized simultaneously.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular, the invention relates to a mobile biogas slurry concentration integrated equipment. Background technique [0002] my country is a big country in the livestock and poultry breeding industry, and the output of meat and eggs ranks first in the world. In recent years, with the improvement of breeding level, the proportion of large-scale breeding in my country's livestock and poultry breeding industry has gradually increased. At present, livestock and poultry breeding industrialization organizations have accounted for more than 50% of the national agricultural industrialization organizations. However, while large-scale livestock and poultry farming brings economic benefits, it also brings great pressure to the environment. According to the Bulletin of the First National Survey of Pollution Sources, in 2007, the total discharge of livestock and poultry manure from pigs, cattle, and chi...

AI Technical Summary

Problems solved by technology

The main reason is that the agricultural application of biogas slurry requires a large amount of land for consumption, and its agricultural demand also has obvious seasonality, but the production of biogas slurry is huge all the year round, and there are often not enough agricultural facilities for the consumption of biogas slurry near the biogas project. land, resulting in high storage and transportation costs

In addition, the content of nutrients such as nitrogen, phosphorus and amino acids in biogas slurry is relatively low, which also limits the high-value utilization of biogas slurry
