Abstract

The invention relates to a desulfurization wastewater concentration reduction treating system based on a nonsoftening and directional driving electrodialysis technology. The system comprises a wastewater raw water tank, a wastewater raw water pump, a directional driving electrodialysis device, an electrode water tank, an electrode water pump, a wastewater concentrated water tank, a wastewater concentrated water pump, a wastewater fresh water tank and a wastewater fresh water pump. Desulphurization wastewater is connected to an inlet of the wastewater raw water tank, an outlet of the wastewaterraw water tank is connected with a wastewater inlet of the directional driving electrodialysis device through the wastewater raw water pump; a concentrated water outlet of the directional driving electrodialysis device is connected with an inlet of the wastewater concentrated water tank; an outlet of the wastewater concentrated water tank is connected to a final treating system through the wastewater concentrated water pump; a fresh water outlet of the directional driving electrodialysis device is connected with the wastewater fresh water tank which is connected to a desulfurization system through the wastewater fresh water pump. The desulfurization wastewater concentration reduction treating system has the beneficial effects that the directional driving electrodialysis device is arranged, so that the desulfurization wastewater can be effectively concentrated and reduced on the premise of not removing the hardness of calcium and magnesium in the wastewater, namely nonsoftening.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment, and specifically relates to a coal-fired power plant wet desulfurization wastewater concentration and reduction treatment system and method based on non-softening and directional-driven electrodialysis technology. Background technique [0002] During the operation of the wet limestone desulfurization process, part of the discharged wastewater will be generated, commonly known as desulfurization wastewater. The main purpose of discharging desulfurization wastewater is to discharge the chlorine salts, fluorides, magnesium salts, heavy metals and some suspended solids that are continuously enriched during the operation of the desulfurization system, so as to ensure the continuous desulfurization reaction. Due to the large amount of desulfurization wastewater and high salt content, the terminal treatment of desulfurization wastewater (direct bypass flue gas evaporatio...
