Description

Waste water treatment device and glass cleaning machine Technical Field The invention belongs to the technical field of wastewater treatment, and particularly relates to a wastewater treatment device and a glass cleaning machine. Background Automotive glass, as a key component affecting driving safety and vehicle appearance, has extremely high requirements on its appearance quality and optical properties (e.g., light transmittance, optical distortion). The achievement of these properties depends to a large extent on the degree of surface cleanliness of the glass after it has been processed, for example, by dicing, edging. Impurities such as glass dust, edging slurry and the like remained in the cleaning link can become a defect source in the subsequent tempering or interlayer process if not thoroughly cleaned, so that the problems of unacceptable optical distortion, inclusion and the like of finished glass are caused, and the grade and safety performance of the product are seriously affected. At present, a cleaning machine is generally adopted in the industry to clean the processed glass. Conventional washers typically have a separate water tank configured to supply and circulate water. In the aspect of water treatment, it is common practice to simply arrange coarse filter media such as filter cotton in a water tank, and to perform disposable filtration on the returned cleaning wastewater. The treatment mode can not ensure the final cleaning quality of the glass due to insufficient cleanliness, becomes a potential cause of optical defects of the product, and often has to adopt a strategy of frequently changing water, such as discharging and replacing the whole tap water every day, in order to avoid the influence of water quality deterioration on the production. The mode temporarily maintains the cleaning effect, but causes huge consumption of water resources, and increases the energy cost of water treatment and heating, which is seriously different from the current development trend of energy conservation, consumption reduction and green production in the manufacturing industry.
