Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and more specifically to a chicken farm wastewater treatment device. Background Art

[0002] Nowadays, the pollution of water bodies by wastewater from chicken farms is becoming increasingly serious. Chicken houses are often flushed and hatcheries are also regularly flushed and disinfected, generating a large amount of wastewater. Chicken manure wastewater not only contains high concentrations of organic pollutants and high concentrations of solid suspended matter, but is also rich in nutrients such as nitrogen and phosphorus, and has a high ammonia nitrogen content. This brings great difficulties to the biochemical treatment of chicken manure wastewater, especially denitrification treatment. Before treating the wastewater, sedimentation treatment is usually required to remove larger particles of chicken manure in the wastewater.

[0003] In the current aquaculture wastewater treatment process, wastewater from chicken farms is first introduced into a sedimentation tank, where it undergoes a natural settling process to achieve initial solid-liquid separation. Subsequently, the relatively clear upper water layer is discharged, while the sediment rich in chicken manure remains at the bottom of the tank. However, a significant technical challenge is that the precipitated chicken manure, due to its inherent viscosity, tends to adhere tightly to the inner wall of the sedimentation tank, increasing the complexity and labor intensity of subsequent cleanup work.
