Description

Technical Field

[0001] The invention relates to the technical field of laying duck breeding, and in particular to a laying duck biological purification green treatment system. Background Art

[0002] Laying duck refers to the stage from the beginning of egg-laying to the elimination of female ducks. Generally, the utilization period of egg-laying ducks is about 350 days (150-500 days old), which is called the first egg-laying year. Some ducks are utilized in the second and third years after molting, but their production performance declines year by year and they should not be retained. Due to continuous egg-laying, they consume a lot of nutrients. For example, if one egg is laid every day and the egg weight is 65g, 8.75g of crude protein is required (calculated based on 13.5% crude protein in the whole egg) and 9.43g of crude fat (calculated based on 14.5% crude fat content in the whole egg). In addition, a large amount of inorganic salts and various vitamins are needed. If the nutrients in the feed are not comprehensive or lack certain elements, the egg production will decrease, such as a decrease in the number of eggs, delayed egg laying, rough eggshells or weight loss of ducks, loose feathers, loss of appetite, slow reaction, fear of going into the water, etc. Therefore, laying ducks require higher quality feed. In the mass breeding of laying ducks, a large amount of feces will be produced, which will lead to eutrophication of water quality. Therefore, biological purification treatment equipment is needed to treat the water.

[0003] However, in actual application, most of the treatment methods are to replace water, which causes eutrophic water to affect the environment after discharge. At the same time, it will also affect the water quality when it flows into other water sources. It is impossible to carry out biological purification and recycling of water, which affects the ecology. Summary of the invention
