Desulfurization softening treatment device for industrial wastewater

Abstract

The invention discloses a desulfurization and softening treatment device for industrial wastewater. The device comprises a precipitation tank, wherein the top of one side of the precipitation tank iscommunicated with an external sewage pipe, the two ends of the bottom surface of the precipitation tank are fixedly connected with the top ends of damping springs respectively, a first filter box is mounted below the precipitation tank, the bottom of one side of the first filter box is fixedly connected with the input end of a water pump through a water pipe, the output end of the water pump communicates to the top of one side of a second filter box through a water pipe, the bottom of the other side of the second filter box is communicated with the top of one side of a desulfurization tank through a horizontally mounted water pipe, the top of the other side of the desulfurization tank is fixedly connected with the input end of an induced draft fan through a vent pipe, and the output end ofthe induced draft fan is communicated with the bottom of one side of a tail gas treatment device through a vent pipe. In the use process, the desulfurization efficiency of wastewater is improved, thezero emission function is realized, and the environmental protection effect of the equipment is improved.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a desulfurization and softening treatment device for industrial waste water. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. There are many types of industrial wastewater with complex components. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Therefore, it is necessary to develop comprehensive utilization, turn harm into benefit, and take corresponding purification measures for disposal according to the pollutant composition and concentration in the wastewater. can be discharged.

AI Technical Summary

Problems solved by technology

Desulfurization and softening is a very important step in the treatment of industrial wastewater, but the existing equipment does not have the function of tail gas treatment when desulfurizing and softening industrial wastewater, resulting in many waste gases generated during the treatment of wastewater being directly discharged to In the atmosphere, it greatly affects the air quality of the surrounding environment, and when wastewater is treated, the sewage in the wastewater must be filtered first. The existing equipment either directly lacks this step, or after filtering a part of the wastewater, it needs to be filtered. Filtration is performed after precipitation is completed. There is a lot of waiting time in this process, which greatly reduces the efficiency of wastewater treatment.
