Mechanical treatment device for highly polluted wastewater

Abstract

The invention discloses a mechanical treatment device for highly polluted wastewater. The device comprises a base plate, a stirring component, a filtering component and a reverse osmosis component. The stirring component is arranged on one side of the top side of the base plate, and a stirring rod is arranged in the stirring component. The filter component comprises a filter box and a filter plate, wherein the filter box is arranged in the middle of the top surface of the base plate and provided with two filter plates or more in the longitudinal direction, and the filter plate is provided withfilter holes. The top end of one side of the filter box is connected with a stirring cylinder through a first infusion pipe, and a second infusion pipe connected on the other side of the filter box is provided with two dividing pipes. The reverse osmosis component is arranged below the two dividing pipes and mounted on the other side of the top surface of the base plate, and comprises a housing,a lower press plate and an oil cylinder. A wastewater chamber and a fresh water chamber are arranged inside the housing. A reverse osmosis membrane is longitudinally arranged between the wastewater chamber and the freshwater chamber, and the wastewater chamber is pressurized by the lower press plate under the action of the oil cylinder. The invention improves the recycling rate of the wastewater and effectively improves the treatment efficiency of the wastewater.

Description

technical field [0001] The invention belongs to the field of waste water environmental protection treatment, in particular to mechanical treatment equipment for highly polluted waste water. Background technique [0002] At present, limestone-gypsum wet desulfurization is the mainstream desulfurization process in thermal power plants at home and abroad, but this process will produce desulfurization wastewater with high salt content, and its Cl ion content can reach 5000-2000mg / L. The existing desulfurization wastewater treatment process only removes heavy metal ions and SS in water, but due to the limitation of the process principle, the ability to remove salt is extremely weak, especially the ability to remove Cl ions is weak, so that Cl ions continue to flow in the water. Enrichment. [0003] At present, there are few power plants that realize the reuse of desulfurization wastewater and achieve zero discharge, and the evaporation and crystallization process is mainly used....

AI Technical Summary

Problems solved by technology

By evaporating, concentrating, and solidifying the desulfurization wastewater, recovering the condensed water generated during the evaporation process, and at the same time turning the wastewater into solid salt and transporting it abroad, realizing zero discharge of wastewater and reusing wastewater; the investment cost and operating cost of this process are both High, and the system is more complex, difficult to promote
