Problems solved by technology
[0004] In order to overcome the deficiencies in the residual pollution and other aspects of the prior art methods, the present invention proposes a method for purifying sodium hexadecyl diphenyl ether monosulfonate with ozone. By detecting the concentration of pollutants and adjusting the reaction temperature, ten Sodium hexaalkyldiphenyl ether monosulfonate is completely decomposed into water, Na + , SO 3 2- and carbon dioxide that can be emitted, and calculate the amount of ozone required for the complete decomposition of sodium cetyl diphenyl ether monosulfonate, and achieve efficient treatment of pollutants by adjusting and controlling the opening of the water outlet valve and the flow of ozone.

Embodiment Construction
[0014] Refer to attached figure 1 ,Specific steps are as follows:
[0015] 1. At a temperature of 10~40 , When the ozone content in the wastewater reaches 3.5mg / L or more, according to the reaction formula
[0016]
[0017] Ozone can completely oxidize and decompose sodium hexadecyl diphenyl ether monosulfonate, oxidatively break the double bond and further break the hydrogen bond to generate water, Na + , SO 3 2- and carbon dioxide that can be emitted, eliminating the hazards of the original sodium hexadecyl diphenyl ether monosulfonate molecule and its reaction derivatives to water quality;
[0018] 2. By detecting the concentration of pollutants in the wastewater, the temperature is controlled at 10~40 , the concentration of sodium cetyl diphenyl ether monosulfonate at the sewage water inlet is 600mg / L, and the relative molecular mass of sodium cetyl diphenyl ether monosulfonate is 496, so it can be calculated that ten The mass of sodium hexadecyl diphenyl ether ...

The invention belongs to the technical field of traffic environments, discloses an automotive wastewater treatment method and particularly relates to a method using ozone for purification treatment of sodium hexadecyl diphenyl ether monosulfonate. The sodium hexadecyl diphenyl ether monosulfonate is completely decomposed to water, Na+, SO32- and dischargeable carbon dioxide by means of pollutant concentration detection and reaction temperature adjustment so that the shortages of residual pollution and the like of existing technical methods are overcome, and efficient treatment of pollutants can be achieved by computing the ozone amount required by complete decomposition of the sodium hexadecyl diphenyl ether monosulfonate and adjusting and controlling openness of a water outlet valve and ozone feeding flow rate.
Description
technical field [0001] The invention relates to a method for treating automobile wastewater, in particular to a pollution-free and efficient treatment method, and belongs to the technical field of traffic environment. Background technique [0002] In recent years, with the rapid development of China's economy and the introduction of a series of national policies to stimulate automobile consumption, the number of motor vehicles on the street has increased geometrically, and the car wash industry has also developed rapidly. It is often discharged into sewers, streets, flowers and plants without any treatment to cause pollution, and sodium cetyl diphenyl ether monosulfonate is often used as the main pollutant in car wash wastewater. Therefore, it is essential for the treatment of sodium cetyl diphenyl ether monosulfonate in car wash wastewater. [0003] The commonly used car wash wastewater treatment methods include: physical and chemical treatment process, electrolysis method...
