Description

Technical Field

[0001] The invention belongs to the technical field of tourist signboards, and in particular relates to a chlorine ion removal sewage treatment agent and a production device thereof. Background Art

[0002] In the prior art, the following methods are generally used to treat chloride ions in sewage:

[0003] 1. Flocculation precipitation and solvent extraction: Flocculation precipitation mainly uses flocculants to act on chloride ions and remove them by flocculation and precipitation, such as composite flocculants; solvent extraction uses extractants to extract and remove compounds containing chloride ions.

[0004] 2. Oxidation-reduction method: Chloride ions are removed by electrolysis, electrodialysis, or reduction. Application methods include electrolysis, electrodialysis, and adding oxidants. Electrolysis is when electricity is applied to sewage, and a potential difference is generated between the positive and negative electrodes of the electrolytic cell, causing anions in the sewage to move to the anode for oxidation reaction, and cations to move to the cathode for reduction reaction, so that pollutants in the wastewater are oxidized at the anode, reduced at the cathode, or react with electrode reaction products to be converted into harmless components that are separated and removed.

[0005] 3. Silver volume method: Combine silver ion-containing substances with chloride ions to generate silver chloride precipitate, thereby achieving the purpose of removing chloride ions.

[0006] 4. Bismuth oxide method: After adding bismuth oxide reagent to the stock solution, the bismuth ions formed under acidic conditions will hydrolyze with chloride ions within a certain pH range to form water-insoluble bismuth oxide precipitates to remove chloride ions from the stock solution.

[0007] 5. Ultra-high lime aluminum method: also known as Freund's salt method, calcium oxide and sodium aluminate are added to chlorine-containing wastewater, and after reaction under certain conditions, calcium-chloroaluminum compound precipitates are formed to achieve the purpose of removing chloride ions.

[0008] 6. Physical adsorbent (activated alumina): can reduce the concentration of hydrogen chloride to about 3×10-7. Through industrial tests, the operating conditions are: the raw material is hydrogen circulating gas, the temperature is 93°C, the pressure is 0.78Mpa, the air velocity is 2400h-1, the volume fraction of hydrogen chloride in the raw material is 3×10-6, the dechlorinating agent reacts with hydrogen chloride in layers, and when using the physical absorption method (activated alumina) for dechlorination, it needs to be replaced every 4 months, and the penetration chlorine capacity is about 5%.

[0009] These methods have certain effects in different application scenarios, but they also have some limitations, such as high cost, complex operation, and possible secondary pollution. With the increasingly stringent environmental protection requirements, the development of more efficient, economical and environmentally friendly chloride ion removal technology is the future development direction.
