Problems solved by technology

[0004] In order to overcome the deficiencies in aspects such as residual pollution that exists in the prior art method, the present invention proposes a kind of ozone purification treatment method to alkyl sulfate sodium salt, by detecting pollutant concentration, adjust reaction temperature, make alkyl sulfate sodium salt Completely decomposed into water, Na + , SO 4 2- and the carbon dioxide that can be emitted, and calculate the amount of ozone required for the complete decomposition of the sodium alkyl sulfate, and achieve efficient treatment of pollutants by adjusting and controlling the opening of the water outlet valve and the flow of ozone.

Embodiment Construction

[0015] Refer to attached figure 1 ,Specific steps are as follows:

[0016] 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

[0017]

[0018] In the formula: ;

[0019] Ozone can completely oxidize and decompose the sodium salt of alkyl 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 alkyl sulfate molecule and its reaction derivatives to water quality;

[0020] 2. By detecting the concentration of pollutants in the wastewater, the temperature is controlled at 10~40 , the concentration of alkyl sulfate sodium salt at the sewage inlet is 600mg / L, and the relative molecular mass of alkyl sulfate sodium salt is , can calculate the mass of alkyl sulfate sodium salt in one liter of wastewater solution, and then convert it into molar mass ...

Abstract

The invention relates to a method using ozone for purification treatment of alkyl sulfate sodium salt. The alkyl sulfate sodium salt 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 alkyl sulfate sodium salt 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 the sodium alkyl sulfate is often the main pollutant in car wash wastewater. Therefore, it is essential for the treatment of sodium alkyl 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 seed and magne...
