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 for dodecyl sulfate monoethanolamine, by detecting the concentration of pollutants, adjusting the reaction temperature, making lauryl sulfate Monoethanolamine is completely decomposed into water, NH 4 + , SO 4 2- and the carbon dioxide that can be emitted, and calculate the amount of ozone required for the complete decomposition of monoethanolamine lauryl sulfate, and achieve efficient treatment of pollutants by adjusting and controlling the opening of the water outlet valve and the incoming ozone flow

Embodiment Construction

[0014] Refer to attached figure 1 ,Specific steps are as follows:

[0015] 1. At a temperature of 10~40 , pH value below 6, when the ozone content in the wastewater reaches above 3.5mg / L, according to the reaction formula

[0016]

[0017] Ozone can completely oxidize and decompose monoethanolamine lauryl sulfate, oxidatively break the double bond and further break the hydrogen bond to generate water and NH 4 + , SO 4 2- and carbon dioxide that can be emitted, eliminating the hazards of the original dodecyl sulfate monoethanolamine molecule and its 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 monoethanolamine lauryl sulfate in the sewage water inlet is 300mg / L, and the relative molecular mass of monoethanolamine lauryl sulfate is 325, and the quality of monoethanolamine lauryl sulf...

Abstract

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 monoethanolamine dodecyl sulfate. The monoethanolamine dodecyl sulfate is completely decomposed to water, NH4+, 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 monoethanolamine dodecyl 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 lauryl sulfate monoethanolamine is often the main pollutant in car wash wastewater. Therefore, it is essential for the treatment of lauryl sulfate monoethanolamine in car wash wastewater. [0003] The commonly used car wash wastewater treatment methods include: physical and chemical treatment process, electrolysis method, membrane bioreactor, magne...
