In the past two years, environmental pollution and environmental protection are concerned by the whole country. There are only two kinds of environmental problems in the pig farm: one is to prevent the pollution of the external environment to the pig farm, the other is the environmental pollution inside the pig house to the external environment. Therefore, China's aquaculture industry is facing serious environmental problems. How to do these measures well?

1. It is necessary to find out the source of the disaster inside the pigsty, that is, the problem of manure and sewage. The manure and sewage must be properly treated. After being treated by the solid-liquid separator, the manure and urine can be used as fertilizer or fish feed.

2. Reasonable planning of pigsty. The reasonable planning of pigsty can solve the internal and external pollution problems of pigsty in advance. The site selection of pig farm should be high and dry, sunny and leeward, with a certain slope, which is conducive to lighting, ventilation and drainage. The water source should be sufficient and the water quality should be good. And the traffic should be convenient.

3. Protect the water source, prevent the water source from being polluted, and pay attention to the control of drainage.

4. Green the pig farm. The afforesting of pig farm can improve the temperature, humidity and air flow in pig house, purify the air, block harmful gas, reduce noise and beautify the environment.

  The above suggestions are from my personal experience and environmental protection requirements, and I hope to help the majority of breeding friends!
