Lead-zinc mine wastewater treatment equipment

Lead-zinc mine wastewater treatment equipment is a professional equipment for treating wastewater generated during lead-zinc mining and beneficiation. It is designed to remove harmful substances in wastewater and achieve wastewater purification and recycling. The following are some commonly used lead-zinc mine wastewater treatment equipment and their functions: 1. Pretreatment equipment - Vibrating screen: used to remove large suspended particles in wastewater. - Grit chamber: removes sand and heavy particles in wastewater by gravity sedimentation. 2. Solid-liquid separation equipment - Filter press: including belt filter press and plate and frame filter press, used for sludge dewatering. - Centrifuge: uses centrifugal force to separate solids and liquids, suitable for wastewater with finer particles. 3. Chemical treatment equipment - Coagulation sedimentation tank: by adding coagulants, the suspended matter in the wastewater is condensed into larger particles for subsequent treatment. - Neutralization tank: adjusts the pH value of the wastewater and removes acidic or alkaline substances in the wastewater through acid-base neutralization reaction. 4. Sedimentation equipment - Clarification tank: used to further remove suspended matter formed after chemical treatment. - Gravity sedimentation tank: Use gravity to settle suspended matter and discharge the upper layer of clear water. 5. Filtration equipment - Filters: Such as sand filter, activated carbon filter, etc., used to remove tiny suspended matter and organic matter. 6. Disinfection equipment - Ozone generator: Used to disinfect wastewater, remove odor and some organic matter. - Ultraviolet disinfector: Use ultraviolet light to irradiate wastewater for disinfection. 7. Reuse and discharge equipment - Reverse osmosis equipment: Used for deep treatment of wastewater to achieve water recycling. - Discharge pump: Used to discharge treated wastewater to a designated location. 8. Automatic control system - PLC programming controller: Used to automatically control the wastewater treatment process to ensure stable operation of the system. - Online monitoring instrument: Real-time monitoring of key parameters in the wastewater treatment process, such as pH value, suspended matter concentration, etc. When selecting lead-zinc mine wastewater treatment equipment, the following factors should be considered: - Wastewater characteristics: wastewater composition, water volume, solid content, etc. - Treatment target: Determine the degree of treatment according to the discharge standard or reuse requirements. - Equipment performance: equipment processing capacity, dehydration efficiency, energy consumption, degree of automation, etc. - Environmental regulations: ensure that the equipment can meet local environmental regulations. - Operating costs: equipment operation, maintenance costs and reagent costs. Reasonable configuration and operation of lead-zinc mine wastewater treatment equipment can effectively reduce pollutant emissions, protect the environment, and realize the recycling of resources.
