Embodiment 1

[0057] Embodiment 1, the method for chlorine ion removal and chlorine removal slag regeneration chlorine removal agent for chlorine ion in power plant wastewater

[0058] In this embodiment, the dilute sulfuric acid solution of stannous sulfate is used as the chlorine removal agent, wherein the concentration of tin ions is 200g / L, and the concentration of sulfuric acid is 100g / L; The pH value of the wastewater is 9-10, and the chloride ion concentration in the wastewater is 800mg / L.

[0059] The specific implementation of this embodiment includes the following steps:

[0060] The first step is to obtain chlorine removal residue.

[0061] Measure the dechlorination agent according to 1.5% (volume ratio) of the total amount of wastewater to be treated, and dechlorinate the wastewater under the condition of constant stirring, which can reduce the chlorine ions in the wastewater to below 100mg / L. The dechlorination principle is:

[0062] sn 2+ +Cl - +H 2 O=Sn(OH)Cl↓+H +

Abstract

The invention discloses a chloride ion removal and dechlorination slag regeneration dechlorination agent integrated production line and method, the production line comprises a chloride ion removal system, a dechlorination slag regeneration system and a tail gas purification system, the dechlorination slag regeneration system comprises a dechlorination slag regeneration furnace, a hot blast stove, a regenerated catalyst container, a pH regulator container and a medicament adding pipe, one side of the chlorine slag removal regeneration furnace is provided with a furnace door through which a chlorine slag removal material boat enters and exits, the regenerated catalyst container and the pH regulator container are respectively converged and communicated with one end of a medicament adding pipe through a regenerated catalyst adding branch pipe and a pH regulator adding branch pipe, and the other end of the medicament adding pipe extends into the chlorine slag removal regeneration furnace; a regenerated catalyst adding valve and a pH regulator adding valve are respectively arranged on the regenerated catalyst adding branch pipe and the pH regulator adding branch pipe; and the chlorine slag removal regeneration furnace is communicated with a tail gas purification system through a tail gas exhaust pipe. The method has the advantages of simple process, low cost and small wastewater amount.

Description

technical field [0001] The invention belongs to the technical field of chlorine ion removal of harmful elements in aqueous solution, and in particular relates to an integrated production line and method for chlorine ion removal, chlorine residue removal and chlorine removal agent regeneration. Background technique [0002] Chlorine-containing wastewater has the characteristics of complex composition, large water volume and wide distribution. These wastewater mainly come from related chemical industries, iron and steel production, aluminum electrolysis and aluminum processing, acid production and sulfur-containing fertilizer production, glass product manufacturing and processing, non-ferrous metal smelting And industries such as thermal power generation. At the same time, the chlorine content in surface water and groundwater in some areas also seriously exceeds the standard. [0003] The existence of high concentrations of chloride ions in water has caused great harm to human...
