Design and Application of Copper Metal Material Cleaning Pollution Water Treatment Equipment

Design and Application of Copper Metal Material Cleaning Pollution Water Treatment EquipmentCopper metal materials are widely used in industrial production, and the surface cleaning process generates polluted water containing heavy metal ions, grease, and cleaning agent residues. If this type of wastewater is directly discharged, it will not only cause serious pollution to soil and water bodies, but may also pose a threat to human health through the food chain. Therefore, the development of efficient and economical copper metal material cleaning and pollution water treatment equipment has important environmental significance and application value.

Design and Application of Copper Metal Material Cleaning Pollution Water Treatment EquipmentWorking principle and core technology of equipment

Copper metal material cleaning pollution water treatment equipment usually adopts a three-stage process design of pretreatment deep treatment reuse. In the pretreatment stage, suspended particles and copper shavings in the water are removed through grid filtration, and then enter the regulating tank to balance the water quality and quantity; The deep processing unit is the core component, and currently mainstream technologies include chemical precipitation, ion exchange, and membrane separation. Among them, the chemical precipitation method forms copper ion precipitates by adding hydroxides or sulfides, which is suitable for the treatment of high concentration copper containing wastewater; The ion exchange method utilizes selective adsorption of copper ions by resin to achieve separation, which can reduce the concentration of copper ions to below 0.1mg/L; The reverse osmosis process in membrane separation technology can effectively intercept heavy metal ions and organic matter in water, and the effluent quality can meet the standards for reuse.

The device integrates an intelligent control system, which collects key parameters such as pH value, copper ion concentration, and turbidity in real time through online monitoring sensors, and automatically adjusts the dosage and processing flow of chemicals. For example, when the copper ion concentration exceeds the set threshold, the system will activate the backup ion exchange column to ensure that the effluent is stable and meets the standard. In addition, the equipment is equipped with a sludge dewatering device, which compresses the copper containing sludge generated by chemical precipitation into a sludge cake for subsequent resource recovery.

Equipment structure and performance characteristics

A typical copper metal material cleaning and pollution water treatment equipment consists of the following modules:

Inlet unit: including grid machine, lift pump, and flow meter, responsible for collecting and preliminary filtering wastewater

Reaction unit: composed of pH regulating tank, flocculation reaction tank, and sedimentation tank, which removes most copper ions through chemical reactions

Deep processing unit: Configure ion exchange columns or membrane components according to processing requirements to achieve the removal of trace pollutants

Disinfection unit: UV or ozone disinfection is used to kill microorganisms in water and ensure safe reuse

Self control unit: PLC control cabinet and touch screen, supporting manual/automatic switching and remote monitoring

The core performance indicators of the equipment include: processing capacity of 5-50m ³/h, copper ion removal rate ≥ 99.5%, effluent copper ion concentration ≤ 0.5mg/L (in accordance with the "Emission Standard for Electroplating Pollutants" GB21900-2008), and water reuse rate of over 70%. Compared with traditional processing equipment, this equipment has the advantages of small footprint, high degree of automation, and low operating costs, making it particularly suitable for small and medium-sized copper processing enterprises.
