Abstract

The invention relates to a resourceful treatment system and treatment method for livestock excrements. The resourceful treatment system comprises an excrement collecting tank, a stirring tank, an up-flow solid anaerobic reactor, a dry-wet separator, a biogas slurry storage tank, a biogas purification system, a gas storage film and a power generation system. The invention has the advantages that aprocess route of anaerobic treatment of all the faeces and urine in a farm is adopted, and a large amount of livestock excrements and urine of the farm are subjected to harmless treatment through a biogas ecological project, so pollution sources can be greatly eliminated, the environment is protected, ecology is improved, zero emissions of pollutants is finally achieved, ecological balance is maintained, aquaculture production is allowed to be a virtuous circle, and the adjustment of agricultural structure is promoted.

Description

technical field [0001] The invention belongs to the field of manure resource treatment, and in particular relates to a livestock and poultry manure resource treatment system and a treatment method thereof. Background technique [0002] The livestock and poultry breeding industry is a pillar industry of the rural economy and an important source of farmers' income. However, with the rapid development of the livestock and poultry breeding industry, environmental problems have become increasingly prominent, and it has become one of the main sources of rural environmental pollution. The sewage produced by livestock and poultry breeding has a high concentration of COD and a lot of scum, so it is not suitable to be directly discharged into the domestic sewage treatment station and needs to be treated separately. [0003] The construction of biogas projects and the realization of ecological breeding are the needs of national environmental protection, the need to purify the agricultu...
