Dry collection-based integrated manure treatment method for livestock farm and device

Abstract

The invention discloses a dry collection-based integrated manure treatment method for a livestock farm and a device for the integrated manure treatment method. The method comprises the steps of firstly carrying out solid-liquid separation on livestock manure to treat solid manure and manure wastewater separately, wherein the step of treating the livestock manure comprises the steps of straw mixing, feeding, anaerobic dry fermentation and discharging in sequence; the step of treating the manure wastewater comprises the steps of water feeding, anaerobic fermentation, aerobic pond, constructed wetland and water discharging in sequence. Meanwhile, the invention discloses a device for achieving the manure treatment method. The device comprises a dry manure treatment system, a sewage treatment system and a biogas purification system. Continuous treatment of livestock manure is achieved by using continuous closed feeding and discharging; sewage is treated by using an efficient anaerobic system, so that the floor space required for a manure yard can be reduced, the biogas production efficiency and the system operation stability are improved, stable up-to-standard discharge of breeding sewage treatment is ensured, and meanwhile, the manure treatment cost can be reduced.

Description

technical field [0001] The invention belongs to the field of treatment of livestock and poultry breeding manure. It relates to a biogas dry fermentation device and a high-efficiency anaerobic system. It is an integrated manure treatment method and equipment for livestock and poultry farms based on dry manure cleaning. Specifically, it uses manure as a raw material for anaerobic fermentation treatment. Equipment for manure treatment. Background technique [0002] In recent years, economic development has accelerated the development of livestock and poultry breeding industry, resulting in a large amount of livestock and poultry manure, which not only pollutes the environment, but also affects the sustainable development of the breeding industry. At present, large-scale aquaculture production occupies a dominant position, and the manure treatment process of these farms is particularly important. [0003] At present, according to the way of cleaning manure in farms, there are ...
