Problems solved by technology
[0004] In order to overcome the deficiencies in aspects such as residual pollution in the prior art method, the present invention proposes a method for purifying sodium cetyl sulfonate by ozone, by detecting the concentration of pollutants, adjusting the reaction temperature, and making cetyl sulfonate Sodium bicarbonate is completely decomposed into water, Na + , SO 3 2- and the carbon dioxide that can be emitted, and calculate the amount of ozone required for the complete decomposition of sodium cetyl sulfonate, and achieve efficient treatment of pollutants by adjusting 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 cetyl sulfonate, 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 hexadecylsulfonate 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 sulfonate in the sewage water inlet is 800mg / L, and the relative molecular mass of sodium cetyl sulfonate is 328.49, so the quality of sodium cetyl sulfonate in one liter of wastewater solution can be calculated , and then converted into a molar weight of about 0.0024mol...

The invention discloses an automobile wastewater treatment method, particularly a purifying treatment method of sodium hexadecylsulfonate with ozone, belonging to the technical field of traffic environment. By detecting the pollutant concentration and regulating the reaction temperature, the sodium hexadecylsulfonate is completely decomposed into water, Na<+>, SO3<2-> and dischargeable carbon dioxide, thereby overcoming the defects in residual pollution and other aspects in the method in the prior art; and the amount of ozone required by completely decomposing sodium hexadecylsulfonate is calculated, and the opening of a water outlet valve and the flow of the introduced ozone are regulated and controlled to efficiently treat pollutants.
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 sulfonate is often the main pollutant in car wash wastewater. Therefore, it is essential for the treatment of sodium cetyl sulfonate in car wash wastewater. [0003] The commonly used car wash wastewater treatment methods include: physical and chemical treatment process, electrolysis method, membrane bioreactor, magnetic seed and magne...
