Spray painting wastewater treatment equipment

With the improvement of people's living standards, there is an increasing demand for a better sense of novelty in items. From cars and equipment to household appliances and mobile phones. The processing of automobiles and their components is one of the industries that generates the most spray paint wastewater. Coating wastewater contains resins, surfactants, and heavy metal ions, Oil、PO43-、 Pollutants such as paint, pigments, organic solvents, etc. The use of traditional mixed wastewater for coagulation treatment has poor results. If the discharge is not treated, it will cause significant pollution to the surrounding water quality and environment.

2、 Introduction to the Process Flow of Spray Painting Wastewater Treatment Equipment

The wastewater generated in the production workshop during industrial spray painting wastewater treatment first enters the regulating tank. Before entering the coagulation reaction sedimentation tank, the larger particles and debris in the wastewater are intercepted by a grid. The debris intercepted on the surface of the grille is manually cleaned. After the reaction precipitation, the sediment is discharged into the sludge tank, and the remaining water is pumped to the coagulation reaction tank. Compressed air stirring is turned on, and after stirring for about 30 seconds, the dosing pump is turned on to automatically add the flocculant PAM solution for flocculation. After stirring the reaction for about 30 seconds, the effluent flows automatically to the inclined tube sedimentation tank for solid-liquid separation. The effluent from the inclined tube sedimentation tank flows automatically to the carbon filter, where the remaining organic matter and suspended solids are finally removed by the carbon filter. The effluent from the carbon filter flows automatically to the reuse tank for unified reuse. The sludge from the sedimentation tank is discharged to the sludge tank and regularly dried by a diaphragm pump sludge filter press. After drying, it is recycled by a professional recycling company.

4、 What should I pay attention to when purchasing paint wastewater treatment equipment?

1. Understand the materials used in the equipment

There are usually two types of materials used for buried equipment: fiberglass and carbon steel. When purchasing equipment, it is necessary to inquire with the supplier about the materials used. When the process and other conditions are the same, the price of different materials will vary greatly.

2. Go to the supplier's successful case site to observe the effect

Everything should be based on facts. No matter how the supplier who provides you with the equipment introduces its superior performance, you should ask the supplier to provide previous successful cases and then send someone to inspect its on-site sewage treatment effect. Although it may delay some time, it is indeed crucial.

3. Agreed execution standards for water discharge

Many units fail to specify the standard for sewage treatment in the contract when purchasing buried sewage treatment equipment, which can lead to disputes in the future when environmental protection requirements are raised. Due to different levels of treatment, the cost of sewage treatment can vary greatly.

4. Compare and sign contracts before purchasing, and specify the payment process

Choose several suppliers as references, and then compare their adopted processes, successful cases, prices, and other factors comprehensively.

Sign a formal contract and agree on the delivery, commissioning, and payment process before paying the deposit.
