Energy-saving and environment-friendly coating production wastewater recycling device

Abstract

The invention discloses an energy-saving and environment-friendly coating production wastewater recycling device. The wastewater recycling device structurally comprises a coating production main body,an observing and monitoring platform, a circulation water suction pump, a ladder, an operation control cabinet and a wastewater purifying, treating and recycling device, wherein the right end surfaceof the coating production main body is connected with the wastewater purifying, treating and recycling device; the observing and monitoring platform is mounted on the outer surface of the coating production main body and is connected with the coating production main body through a welding manner. According to the energy-saving and environment-friendly coating production wastewater recycling device, the gravitational potential energy generated when the wastewater enters a treatment device is fully used and is taken as driving force for purifying and treating the wastewater, so that the energyis greatly saved; the wastewater and treatment liquid can be fully stirred and uniformly mixed; meanwhile, the wastewater is continuously aerated; the gas is in full contact reaction with the wastewater during stirring, so that microorganisms and impurities in the wastewater are further dissolved; sediment and silt can be cleaned in time; corrosion and oxidation to the device can be avoided; the service life of the device can be prolonged.

Description

technical field [0001] The invention relates to the field of waste water recycling, more precisely, an energy-saving and environment-friendly coating production waste water recycling equipment. Background technique [0002] Circulating water is a closed-loop water circulation system composed of the water supply and drainage systems of a factory, workshop or section. The waste water generated in the system will be reused after proper treatment, and fresh water will not be supplemented or added in a small amount, and will not be discharged or in a small amount. However, the current recycling of waste water has the following disadvantages: [0003] 1. The uneven mixing of wastewater and treatment solution reduces the utilization rate of treatment solution, resulting in waste, and the degree of aeration treatment for anaerobic microorganisms is relatively light, resulting in a large amount of microorganisms in wastewater, which affects the production of subsequent coatings. [...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an energy-saving and environmentally friendly paint production wastewater recycling equipment to solve the problem of the prior art that the uneven mixing of wastewater and treatment liquid reduces the utilization rate of the treatment liquid, resulting in waste, and The degree of aeration treatment for anaerobic microorganisms is relatively light, resulting in a large amount of microorganisms in the wastewater, which affects the production of subsequent coatings. It is necessary to provide a large power to drive the equipment to treat wastewater, resulting in a waste of energy, and for sediment and sludge. If the removal is not timely and effective, the microorganisms and impurities contained in the sediment and sludge will corrode the defects of the equipment
