Abstract

The invention discloses a desulfurization waste water concentration decrement device. The device comprises a pre-treatment unit and a first electrodialyzer; the first electrodialyzer comprises a firstcompartment, a second compartment, a third compartment and a fourth compartment, wherein the pre-treatment unit is communicated with the second compartment, and a nanofiltration system is installed at a water outlet end of the first compartment; a first concentrated water pipeline and a first fresh water pipeline are arranged at a water outlet end of the nanofiltration system, and the first freshwater pipeline is communicated with a water inlet end of the fourth compartment; a salt adding unit is arranged at the water inlet end of the fourth compartment; a water outlet end of the fourth compartment is communicated with a water inlet end of the first compartment through a pipeline; the desulfurization waste water concentration decrement device further comprises a pure water supply unit, and the pure water supply unit is communicated with water inlet pipelines of the first compartment, the third compartment and the fourth compartment through pipelines. According to the desulfurizationwaste water concentration decrement device, assemblies are little, the cost is low, and the use effect is good.

Description

technical field [0001] The invention relates to separation equipment, in particular to a desulfurization waste water concentration and reduction device. Background technique [0002] The water quality of desulfurization wastewater has the characteristics of high scaling tendency, complex ion composition and high salt content, and the calcium sulfate and calcium sulfite in desulfurization wastewater are in a supersaturated state, which can easily cause scaling problems to wastewater treatment equipment. When concentrating and reducing desulfurization wastewater or performing zero discharge treatment, desulfurization wastewater must be pretreated to solve the problem of easy fouling of desulfurization wastewater. The conventional double-alkali softening pretreatment process needs to add a large amount of chemical agents, which are expensive and produce a large amount of sludge. [0003] The invention patent application with the application number CN201710312017.4 discloses a ...
