Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a multi-stage treatment device for industrial sewage based on sewage treatment. Background Art

[0002] With the acceleration of industrialization, the discharge of industrial wastewater has increased dramatically, which poses a serious threat to the environment and ecosystem. Industrial wastewater contains a large amount of harmful substances. If it is discharged directly without treatment, it will lead to the pollution of surface water, groundwater and soil, and then affect the growth of plants and animals and human health. Therefore, it is particularly important to develop efficient and multi-stage industrial wastewater treatment equipment. Industrial wastewater mainly includes production wastewater and production wastewater, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. In order to effectively deal with the hazards of industrial wastewater, it is necessary to develop multi-stage treatment equipment to gradually treat the wastewater to meet the discharge standards or realize the recycling of wastewater; The announcement number CN111747607B discloses a wastewater treatment device, including a treatment box with a water inlet pipe and a water outlet pipe, a vertical plate is fixedly connected to one side of the top of the treatment box, and a support mechanism is installed on the vertical plate in a sliding and lifting manner. A large number of adsorption particles are introduced into a rotatable storage bag, and the adsorption particles are fully diffused in the wastewater in the treatment box during the rotation of the storage bag and the stirring shaft. The adsorption layer on the adsorption particles adsorbs the suspended particles in the wastewater. The adsorption particles have magnetic properties, and the electromagnet layer arranged on the cap-shaped adsorption plate and the bottom end surface of the storage bag is convenient for adsorbing the adsorption particles floating in the wastewater. After the storage bag and the cap-shaped adsorption plate are lifted upward by the support mechanism, it is convenient for technicians to remove the adsorption particles without using a filter screen for filtering. When the above-mentioned prior art is used, during the sewage treatment process, the adsorption particles are only used to adsorb the suspended impurities in the sewage to achieve the effect of wastewater impurity treatment, but the method is relatively single, and the single-level sewage treatment method lacks the preliminary filtration and screening process. When the suspended impurities contain large particles of impurities, it will directly affect the adsorption efficiency of the adsorption particles. The large particles of impurities may occupy a large number of sites on the surface of the adsorption particles, resulting in the adsorption particles being unable to fully contact and adsorb finer suspended matter, thereby reducing the overall impurity removal effect, and therefore corresponding improvements are needed; The announcement number CN116808711A discloses a multi-stage sedimentation treatment device for industrial sewage, including a placement box, a cleaning mechanism is provided on the top of the placement box, and a sedimentation mechanism is provided on the left side of the placement box; the cleaning mechanism includes a servo motor, and the rear right end of the placement box is fixedly connected to the servo motor. Sewage enters the placement box, cooperates with the servo motor to drive the rotating rod to rotate, and then cooperates with the winding wheel to rotate the winding chain, so that the scraper slides under the action of the slide slot to block the floating objects, and the sewage flows into the central barrel, the floating objects are effectively treated, and the filter screen filters the sewage, and the sediment is left in the sedimentation barrel. Part of the sewage enters the collection plate through the holes, and the other part of the sewage enters the connecting pipe through the gap, and then enters the collection barrel through the connecting pipe, so that the sewage can be better precipitated and filtered. It has an automatic sewage discharge function and is more convenient to use. When in use, the above-mentioned prior art only utilizes a filter net to filter and treat sewage, but it is mainly a static filtration treatment, which usually relies on the gravity or pressure difference of the sewage to push the water flow through the filter medium to remove suspended matter. When treating a large amount of sewage, this method may take a long time to achieve the ideal filtration effect, especially when treating sewage containing a large amount of suspended matter, the filtration speed may be significantly reduced, and the overall filtration method is single, and only filtration is performed, and multi-stage treatment of sewage cannot be achieved. Therefore, corresponding improvements are needed. Summary of the invention
