Device for mixing, reclaiming and recycling steel waste water and municipal sewage

Abstract

The invention discloses a device for mixing, reclaiming and recycling steel waste water and municipal sewage. The device for mixing, reclaiming and recycling the steel waste water and the municipal sewage comprises a steel waste water pretreatment tank and a municipal sewage pretreatment tank; liquid filling openings are formed in the tops of the steel waste water pretreatment tank and the municipal sewage pretreatment tank; filter screens are arranged in the steel waste water pretreatment tank and the municipal sewage pretreatment tank; stirring rolls are arranged on one sides of the filter screens; the steel waste water pretreatment tank and the municipal sewage pretreatment tank are both connected with a mixed reaction tank through pipelines; a rotating rod is arranged in the mixed reaction tank; a stirring paddle is arranged on the rotating rod; a medicine filling opening is formed in the top of the mixed reaction tank; the mixed reaction tank is communicated with a sedimentation tank through a pipeline; the sedimentation tank is communicated with a filter tank through a pipeline; an active carbon layer is arranged in the filter tank; and a permeable membrane is arranged at the bottom of the active carbon layer. The water usage for steel production is guaranteed; meanwhile, large amounts of fresh water resources are saved in the steel production; therefore, the device for mixing, reclaiming and recycling the steel waste water and the municipal sewage, disclosed by the invention, is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of sewage, in particular to a device for mixing, regenerating and reusing iron and steel wastewater and municipal sewage. Background technique [0002] A lot of sewage is produced every day in our life, and the sewage is discharged into the municipal sewage system. This is a kind of water resource that can be reused, and the amount of water resource is huge. Similarly, a lot of wastewater will be produced in industry, especially in steel production enterprises. Steel production will use a lot of water for cooling and dust removal, which consumes a lot of water resources. If pure groundwater is used every time, it puts enormous pressure on the groundwater. If it is possible to combine steel wastewater and municipal sewage into the grid and use the treated sewage for steel production, it will bring about huge changes in steel production and save a lot of water resources.
