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 kind of ozone purification treatment method to glycerol laurate monostearate, by detecting pollutant concentration, adjusting reaction temperature, pH value, Make glyceryl laurate monostearate completely decompose into water and carbon dioxide that can be discharged, and calculate the amount of ozone required for the complete decomposition of glycerol monostearate laurate, control the opening of the water outlet valve and Introduced ozone flow to achieve efficient treatment of pollutants

Embodiment Construction
[0014] Refer to attached figure 1 ,Specific steps are as follows:
[0015] 1. When the temperature is 10~40, the pH value is below 6, and 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 glyceryl laurate monostearate, oxidatively break the double bond and further break the hydrogen bond, generate water and carbon dioxide that can be emitted, and eliminate the original glycerol monostearyl laurate The hazards of ester molecules and their reaction derivatives to water quality;
[0018] 2. By detecting the concentration of pollutants in the wastewater, adjust the wastewater solution to a pH value below 6, and the temperature is between 10 and 40 , the concentration of lauric acid glycerol monostearate at the sewage water inlet is 600mg / L, and the relative molecular mass of lauric acid glycerol monostearate is 540.86, which can be calculated in one liter of wastewater s...

The invention discloses an automobile wastewater treatment method, belongs to the technical field of traffic environment, and particularly relates to a method of using ozone for purifying lauric glycerol monostearate. The method includes that reaction temperature and pH (potential of hydrogen) values are adjusted by detecting pollutant concentration to enable lauric glycerol monostearate to be completely decomposed into water and dischargeable carbon dioxide. The defects of residue pollution and the like in the prior art are overcome, ozone quantity required by complete decomposition of lauric glycerol monostearate can be worked out, and high efficiency in treatment of pollutants can be achieved by regulating openness of a water outlet valve and flow of fed ozone.
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 glycerol monostearate as the main pollutant. Therefore, it is essential for the treatment of glyceryl laurate monostearate 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 a...
