Industrial wastewater advanced treatment cyclic utilization zero discharge equipment

Abstract

The invention relates to the technical field of industrial wastewater advanced treatment, and discloses industrial wastewater advanced treatment cyclic utilization zero discharge equipment which comprises a fixed base, a primary treatment box is fixedly connected to one side of the top end of the fixed base, and a primary wastewater treatment mechanism is arranged in the primary treatment box; the primary wastewater treatment mechanism comprises a filter plate, a driving rotating shaft, a driven rotating shaft, two groups of connecting rods and two groups of cleaning brushes, and a secondary wastewater treatment mechanism is arranged on the other side of the top end of the fixed base. According to the industrial wastewater advanced treatment cyclic utilization zero discharge equipment, solid impurities in wastewater can be filtered through the design of the first-stage wastewater treatment mechanism and the second-stage wastewater treatment mechanism, and after the industrial wastewater subjected to primary treatment is conveyed to a settling tank in the second-stage wastewater treatment mechanism, sufficient mixing and settling of the wastewater and a flocculating agent can be achieved; the mixing effect between the flocculating agent and the wastewater is improved, and the wastewater precipitation treatment effect and the discharge standard are ensured.

Description

technical field [0001] The invention relates to the technical field of advanced treatment of industrial wastewater, in particular to a zero-emission equipment for advanced treatment and recycling of industrial wastewater. Background technique [0002] Industrial wastewater refers to the wastewater and waste liquid discharged during the production process, which contains industrial production materials, intermediate products, by-products and pollutants generated during the production process that are lost with water, and is an important source of environmental pollution, especially water pollution. reason. [0003] The commonly used working wastewater treatment equipment is to physically and chemically treat the wastewater so that it can meet the discharge standards. Most of the existing wastewater treatment will add flocculants for precipitation, but the mixing effect is poor when adding, and the flocculation efficiency is low.

AI Technical Summary

Problems solved by technology

[0003] The commonly used working wastewater treatment equipment is to physically and chemically treat the wastewater so that it can meet the discharge standards. Most of the existing wastewater treatment will add flocculants for precipitation, but the mixing effect is poor when adding, and the flocculation efficiency is low. The treatment is inconvenient, and there are many fixed impurities in industrial wastewater. If priority treatment is not carried out, it will affect the effect of subsequent wastewater sedimentation treatment. Therefore, a zero-discharge equipment for industrial wastewater advanced treatment and recycling is proposed.
