With the rapid development of economy, the national living standard of China is continuously improved, and the matching of grains, vegetables, meat and eggs tends to be reasonable on diet, so that people not only seek to be full but also need to eat well, which means that higher requirements and challenges are provided for the livestock breeding industry, such as the quality and the yield of the meat and the eggs of livestock. However, after the source channels of live pigs in China are diversified, infectious diseases with extremely strong infectivity, such as African swine fever, cause great loss to farms or farmers, and the intelligent, harmless and remote treatment of the pig raising industry is urgent.
At present, the development of livestock breeding industry faces a plurality of bottlenecks, for example, the excrement of livestock can not be cleaned quickly to cause pollution to the atmospheric environment, the breeding mosquitoes of the excrement cause bacteria and virus infection among animals, and the excrement of livestock can not be collected well and recycled to cause serious waste of resources.
In recent years, relevant departments in various regions have developed pollution management methods for livestock breeding industry, and breeding units and individuals are required to complete air pollution correction work of the livestock breeding industry. The environment-friendly attack and solidness fighting is well established, the ecological environment of the blue sky with blue water is created, and the available resources are recycled efficiently, which not only concern the living quality of people, but also concern the future survival of descendants of people. The informatization and networking technology is fully utilized, and the remote treatment of the live pig manure is realized, which is very necessary.
The related data show that: about 38 hundred million tons of livestock and poultry waste is generated in China every year, and about 40 percent of the waste is not reasonably treated and used, so that a great deal of resources are wasted. The recovered excrement can be used for the following purposes after being treated by a relevant physical method, a chemical method, microbial fermentation and the like: (1) the feed can be used for culturing fish and shrimp without polluting water quality, and can be used as fish and shrimp feed and a fertilizer water product; (2) the ecological breeding mode can be established for breeding yellow mealworms, fly maggots and earthworms; (3) and can be used for preparing bio-organic fertilizers for planting, flowers and the like. (4) The excrement in the storage tank is fermented to generate biogas to provide energy for cooking and lighting for residents in rural areas or remote mountain areas. For the above reasons, there is an urgent need for an intelligent, high-recovery-efficiency, low-pollution livestock metabolite treatment and recovery method.
