The use of centrifugal dehydrator for aquaculture wastewater dehydration equipment

Centrifugal dehydrator is a commonly used dehydration equipment in aquaculture wastewater treatment. It can effectively separate solid particles and suspended matter in wastewater, reduce the pollution load of wastewater, and facilitate subsequent treatment or discharge. The following are the use methods and precautions of centrifugal dehydrator in aquaculture wastewater treatment: Working principle of centrifugal dehydrator Centrifugal dehydrator separates solid particles and liquid in wastewater through the centrifugal force generated by high-speed rotation. Because of their high density, solid particles will be thrown to the inner wall of the drum, while the liquid will be discharged through the pores on the drum wall. Steps for using centrifugal dehydrator 1. Pretreatment: Before centrifugal dehydration, wastewater usually needs to be pretreated, such as adjusting the pH value, adding flocculants, etc., to improve the dehydration efficiency. 2. Feeding: Feed the pretreated wastewater into the centrifugal dehydrator. 3. Dehydration: Solid-liquid separation is carried out by centrifugal force, solids form mud cakes, and liquids are discharged. 4. Mud cake treatment: The dehydrated mud cake can be composted, landfilled or further treated. 5. Discharge or reuse: The treated wastewater is discharged or reused according to local environmental protection standards. Centrifugal dehydrator precautions 1. Equipment selection: Select the appropriate centrifugal dehydrator model according to the characteristics and treatment capacity of aquaculture wastewater. 2. Operating parameters: Reasonably adjust the speed, differential speed, feed rate and other parameters to obtain the best dehydration effect. 3. Pretreatment: The purpose of pretreatment is to improve the flocculation effect of solid particles and facilitate centrifugal dehydration. 4. Wear protection: Since the wastewater may contain hard particles, wear-resistant materials should be selected or corresponding protective measures should be taken to reduce equipment wear. 5. Environmental protection requirements: Ensure that the treated wastewater meets environmental discharge standards. 6. Safe operation: Operators should comply with safety regulations and use appropriate personal protective equipment. 7. Maintenance: Regularly maintain and maintain the centrifugal dehydrator to ensure long-term and stable operation of the equipment. Specific applications in aquaculture wastewater treatment-solid-liquid separation: Centrifugal dehydrators can quickly separate suspended solids in wastewater and reduce SS (suspended solids) content. - Concentration reduction: Through dehydration, the concentration of wastewater is significantly reduced, reducing the burden on subsequent treatment facilities. - Resource utilization: The separated solid matter can be further utilized as a resource, such as fertilizer or feed. The use of centrifugal dehydrators in aquaculture wastewater treatment helps to improve treatment efficiency and reduce the impact on the environment. It is one of the key equipment for achieving aquaculture wastewater reduction, resource utilization, and harmless treatment.
