Method and equipment for producing humic acid from livestock and poultry breeding waste

Abstract

The invention discloses equipment for producing humic acid from livestock and poultry breeding waste, and belongs to the technical field of livestock and poultry breeding waste treatment. The equipment includes a multiphase mixer, a catalyst tank, a high-temperature anaerobic biochemical reactor, a high-temperature oxygen consuming biochemical reactor and a multiphase separator which communicate successively, and an extraction separator is arranged at the liquid output end of the multiphase separator to extract the humic acid. Through arrangement of the equipment, the livestock and poultry breeding waste, namely manure, is used and recycled, waste of resources is reduced, and meanwhile, environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding waste treatment, in particular to a method and equipment for producing humic acid from livestock and poultry breeding waste. Background technique [0002] With the rapid development of China's animal husbandry and breeding industry, the scale of the current breeding enterprises is also rapidly moving towards the direction of intensification and scale. At the same time, this large-scale breeding has exposed a variety of very serious problems. The most serious of these problems is the problem of environmental pollution. For example, some large-scale dairy farming enterprises, due to the large scale of breeding, have a breeding scale of more than 10,000 cows, and the feces produced by the 10,000-head dairy farm can reach 70,000 tons per year. As mentioned above, there are various problems in the commonly used treatment technologies such as feces produced every day. For example,...

Problems solved by technology

[0002] With the rapid development of China's animal husbandry and breeding industry, the scale of the current breeding enterprises is also rapidly moving towards the direction of intensification and scale. At the same time, this large-scale breeding has exposed a variety of very serious problems. The most serious of these problems is the problem of environmental pollution. For example, some large-scale dairy farming enterprises, due to the large scale of breeding, have a breeding scale of more than 10,000 cows, and the feces produced by the 10,000-head dairy farm can reach 70,000 tons per year. As mentioned above, there are various problems in the commonly used treatment technologies such as feces produced every day. For example, the treatment method of fermenting feces to generate biogas, the fermentation method is limited in the temperature conditions for generating biogas in cold northern regions, and the processing capacity Compared with such a huge feces production capacity, it is obviously not enough. What is more fatal is that if the pasture is disinfected, some fungi necessary for biogas generation will be killed, which will affect the generation of biogas. From this point of view, it is harmless The chemical treatment method cannot really carry out harmless treatment, and it is in conflict with the epidemic prevention measures of livestock breeding, and the epidemic prevention and disinfection of breeding places is one of the necessary measures to ensure the health of the livestock raised

In addition, because the livestock produced feces, urine, and wastewater for cleaning and disinfection have complex components, the discharge of organic fertilizers made after simple treatment and wastewater treatment will also pose serious pollution risks to the environment; The past few years in different breeding areas of the 10,000-cow dairy farm are the most intuitive manifestation of this serious consequence.
