Analysis And Treatment Of The Organic Pollutants In Petrochemical Industry Wastewater

Petrochemical industry is a complex trade. There are a lot of organic pollutants in the petrochemical industry wastewater. Some of these organic pollutants can't be decomposed, and will build-up in organism and carcinogenic, such as polynuclear aromatic hydrocarbon, aromatic amine, nitrogen heterocyclic compounds etc. Therefore, it is significative for protect water environment to find some methods to treat the organic pollutants in the petrochemical industry wastewater. It is the most important task interested in all over the world to develop a simple and high efficiency method for treating wastewater.From systemic studying a novel method for separating and enriching and analysing the organic pollutants in the petrochemical industry wastewater was proposed that is the solvent sublation-GC-MS technique. The effects of the pH of the solution, air flow rate, the ion strength of the solution, sublation time, the phase ratio and different solvents on the solvent sublation were investigated in details. In the optimal conditions selected the solvent sublation efficiency of the organics is more than 95%. The experimental results proved that this method could be used to separate,...
