[0025] In recent years, the livestock and poultry farming industry has developed rapidly and has become the most active growth point and pillar industry in the rural economy, contributing to the promotion of rural economic development, adjustment of industrial structure and rural industry. At the same time, the pollution problem in the breeding industry has become increasingly prominent, and serious environmental pollution has also directly affected the sustainable development of the regional economy. Pollution prevention and control in the livestock and poultry farming industry has become an important part of rural environmental protection work, which is related to the sustainable development of the rural economy. Solving rural environmental problems has become an urgent and arduous task in the current rural economic and social development. There are large and small breeders in rural areas of my country, with different numbers of breeding. While bringing economic benefits to breeders, they also cause pollution to the environment. With the enhancement of people's environmental awareness and the increase in environmental protection rectification efforts of my country's environmental protection departments, these breeders also need to treat the generated breeding wastewater and discharge it in compliance with the standards. These breeders are limited in scale, and for them, sewage treatment equipment is far beyond their affordability.
