Description

Technical Field

[0001] The invention relates to the technical field of breeding, and in particular to adjustable livestock and poultry breeding wastewater treatment equipment. Background Art

[0002] Farm wastewater contains a large number of pathogens (E. coli, roundworm eggs, etc.) and high levels of organic matter, suspended solids and ammonia nitrogen. If not properly treated, it can enter the groundwater layer through surface runoff and infiltration and pollute the groundwater. A certain amount of farm wastewater is generated during livestock and poultry farming. Since the wastewater contains a large amount of feces, professional wastewater treatment equipment is needed to treat the feces in it to avoid feces in the wastewater from polluting the environment.

[0003] Most of the existing sewage treatment equipment uses a filter to filter out solid feces in the sewage, and then treats the liquid pollutants in the sewage. When the pollutant concentration in the sewage is reduced to the emission standard, the water is discharged. Although this treatment method can treat sewage, during use, a certain amount of liquid sewage will still remain in the solid feces in the sewage. At this time, the solid feces with a certain amount of liquid sewage is not only heavy, but also continuously releases leachate, which makes subsequent treatment inconvenient. Summary of the invention
