Embodiment 1
[0030] Add 878.5g of tert-butanol and 255g of water into a 5000ml four-neck flask, add 292.5g of phenylhydrazine under a nitrogen atmosphere, stir vigorously, add 112.5g of acetaldehyde dropwise at 15-20°C, keep warm for 30min, add 203.5g of cyanic acid after the reaction is complete Sodium, add 632g of 36% acetic acid aqueous solution dropwise to the flask until the temperature is less than 0.5%, add 2142.5g of sodium hypochlorite dropwise to the flask, and keep the temperature at 35-40°C. After the reaction was completed, 1035 g of the tert-butanol solution was distilled, and the aryl triazolone solid was filtered out, washed with water and then dried. The remaining 2781 g of the filtrate was aryl triazolone high-salt wastewater, which was used for the treatment of subsequent examples.
Embodiment 2
[0032] Add aryl triazolone high-salt waste water 100g in the 250ml four-necked flask, add 19.1g of caustic soda at a uniform speed in the rapid stirring until the alkali content is 16%, exothermic heat rises in the dissolving process of caustic soda, slowly cools down to 50°C, after the crystallization is complete, filter to obtain 5.8g of yellow solid salt, which is the crude sodium chloride; The temperature was 4°C, and then chlorine gas was introduced under rapid stirring until the free alkali content was lower than 1%. During the process of chlorine gas introduction, crystals were precipitated, stirred at a uniform speed until the crystallization was complete, and then filtered to obtain 9.3 g of filter cake, which was crude sodium chloride. After the removal of sodium chloride, the sodium hypochlorite-containing wastewater was tested to have an effective chlorine content of 13.5%, a sodium chloride content of 7.2%, and a sodium acetate content of 8.5%.

Embodiment 3
[0035]In the 250ml four-necked flask, add aryl triazolone high-salt waste water 100g, add cauline soda 21.9g at a uniform speed in the rapid stirring until the alkali content is 18%, exothermic heat rises during the caustic soda dissolving process, slowly cools down to 55°C, after the crystallization is complete, filter to obtain 5.6g of yellow solid salt, which is the crude sodium chloride; The temperature is 6°C, and then chlorine gas is introduced under rapid stirring until the free alkali content is lower than 1%. During the process of chlorine gas ventilation, crystals are precipitated, stirred at a uniform speed until the crystallization is complete, and then filtered to obtain 9.8g of filter cake, which is crude sodium chloride. After the removal of sodium chloride, the sodium hypochlorite-containing wastewater was tested to have an effective chlorine content of 12.8%, a sodium chloride content of 7.5%, and a sodium acetate content of 8.1%.
