1、 Overview of the Development of Aquaculture Waste Treatment Industry
Farming waste refers to the livestock and poultry emissions generated during the livestock and poultry breeding process, as well as the pollutants generated during the disposal or breeding of livestock and poultry carcasses. Animal husbandry waste treatment is the harmless, resourceful, and reduced treatment of the waste generated during the process of animal husbandry.
2、 Development status of aquaculture waste treatment industry
Poultry plays an important role in aquaculture production in China. In recent years, domestic poultry inventories in China have shown a fluctuating upward trend. According to data from the National Bureau of Statistics, the national poultry stock will reach 6.78 billion in 2020, an increase of 260 million compared to 2019.
3、 Policies related to the treatment of aquaculture waste industry
The Regulations on the Prevention and Control of Pollution in Large scale Livestock and Poultry Farming, which came into effect on January 1, 2014, is the first normative document in China specifically aimed at the prevention and control of pollution in livestock and poultry farming. From 2015 to 2018, it was the year with the strictest enforcement of prohibition policies. According to regulations such as the Environmental Protection Law, the Animal Husbandry Law, and the Technical Guidelines for Delimitation of Prohibited Areas for Livestock and Poultry Breeding, a series of regulations have been made on the closure, relocation, and related rewards and punishments of breeding farms in designated places such as environmental protection areas, scenic spots, residential areas, scientific and cultural areas. After 2018, environmental protection policies have been relaxed, emphasizing flexible management while adhering to environmental protection. Multiple departments of the country have issued documents to regulate the unreasonable phenomenon of "one size fits all" in the implementation of environmental protection policies.
4. Environmental protection measures for animal husbandry
In recent years, the development of modern society has greatly improved people's quality of life. At the same time, the demand for animal husbandry products is gradually increasing, and animal husbandry is flourishing. However, due to the lack of ecological and environmental protection concepts among some farmers, they do not have sufficient funds to introduce advanced environmental protection equipment and technology, resulting in serious environmental pollution problems. Therefore, major breeding farms should also adapt to local conditions and do a good job in animal husbandry and environmental protection. At the same time, in order to better ensure the economic benefits of breeding farms, major breeding farms should gradually increase investment, optimize relevant technologies, and improve the efficiency of the breeding industry. Development can be carried out under the premise of meeting environmental protection requirements, so that China's animal husbandry can achieve sustainable development.
