Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment equipment, and particularly relates to a color-coated roll degreasing wastewater treatment equipment. BACKGROUND

[0002] The core purpose of degreasing wastewater treatment in the production process of color-coated rolls is to efficiently remove pollutants such as oil (including emulsified oil, dissolved oil), alkali substances, surfactants, suspended solids and high-concentration chemical oxygen demand (COD) in wastewater, to ensure that the water quality after treatment meets the national or local discharge standards, to meet the water quality requirements of enterprise internal recycling, and to avoid direct discharge to cause damage to the ecological environment of the receiving water body. Untreated degreasing wastewater discharged into the water body will lead to eutrophication of the water body, decrease of dissolved oxygen and increase of biological toxicity, seriously damaging the aquatic ecosystem; seepage into the soil will pollute the groundwater and threaten human health and agricultural safety. Through deep treatment, the wastewater is recycled for degreasing or rinsing process, which greatly reduces the fresh water consumption and water intake cost, and reduces the wastewater discharge treatment cost.

[0003] In the prior art, the biological membrane technology is often used for the treatment of color-coated roll degreasing wastewater. The injected wastewater is increased in pressure to pass through the top of the biological membrane, so that the dissolved organic matter is degraded by the biological membrane. However, when the water pressure is too high or too low, the time for the wastewater to pass through the inside of the biological membrane filler may deviate greatly, resulting in incomplete degradation of the wastewater. On the other hand, the oil part in the wastewater is also easy to adhere to the inner wall of the treatment equipment, so that even if the top adsorption material is specially used for adsorbing oil, the oil in the adhesion area cannot be removed, which is easy to cause the occurrence of cleaning dead angle.

By injecting micro-bubbles into the wastewater, the emulsified oil and colloidal particles adhere to the bubbles and float up, and the micro-bubbles are sprayed along the position close to the inner wall of the tank, so that the oil part adhering to the inner wall can also be diffused and floated up, enhancing the treatment effect of the oil.
