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 the sodium salt of n-butyl oleate sulfate, oxidatively break the double bond and further break the hydrogen bond to generate water, Na + , SO 4 2- and carbon dioxide that can be emitted, eliminating the hazards of the original sodium n-butyl oleate sulfate 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 oleic acid n-butyl sulfate sodium salt at the sewage water inlet is 600mg / L, and the relative molecular mass of oleic acid n-butyl ester sulfate sodium salt is 457.62, can calculate the oleic acid n-butyl ester sulfuric acid in one liter of waste water solution ...

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 butyl oleate sulfate. The sodium butyl oleate sulfate is completely decomposed to water, Na+, SO42- 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 butyl oleate sulfate 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 car wash wastewater often uses n-butyl sulfate sodium salt as the main pollutant. Therefore, it is essential for the treatment of sodium n-butyl oleate sulfate in car wash wastewater. [0003] The commonly used car wash wastewater treatment methods include: physical and chemical treatment process, electrolysis method, membrane bioreactor, magnetic ...
