Application of centrifugal dehydrator in aquaculture wastewater

The application of centrifugal dehydrators in the breeding industry is mainly reflected in the treatment of breeding wastewater, especially the solid-liquid separation of a large amount of feces and wastewater generated during the breeding process. The following are several aspects of the application of centrifugal dehydrators in breeding: 1. Feces treatment: Centrifugal dehydrators can effectively dehydrate animal feces and separate solids and liquids. The dehydrated solid feces can be sold as organic fertilizer or used to make pellet feed, bringing additional economic benefits to the farm. 2. Wastewater purification: Through centrifugal dehydration, the content of suspended solids in wastewater can be reduced, the chemical oxygen demand (COD) and biological oxygen demand (BOD) can be reduced, thereby reducing pollution to the environment. 3. Reduce odor: Due to the reduction in water content, the dehydrated solid feces can significantly reduce the generation of odor and improve the environmental quality around the farm. 4. Resource utilization: Solid waste such as dry cow dung treated by the centrifugal dehydrator can be used as fertilizer or mixed with straw bran and fermented to make compound organic fertilizer, which helps to realize the resource utilization of breeding waste. 5. Energy saving and emission reduction: It reduces the discharge of wastewater, reduces the burden on sewage treatment facilities, and reduces energy consumption and operating costs. 6. Convenience and adaptability: Centrifugal dehydrators are usually compact in design, occupy a small area, are easy to install and carry, and are suitable for farms of various sizes. 7. High degree of automation: Centrifugal dehydrators can usually achieve automatic control, reduce manpower requirements, and improve processing efficiency. In actual applications, centrifugal dehydrators usually need to be used in conjunction with other processing units (such as pretreatment units, flocculation units, etc.) to achieve the best dehydration effect and processing efficiency. In addition, the operation and maintenance of centrifugal dehydrators also require professional technicians to ensure their stable operation and long-term benefits.
