At present, the organic pollution of drinking water source is relatively serious. The organic pollutants themselves are not only highly toxic, but also may generate halogenated disinfection by-products (DBPs) after chlorination disinfection. Meanwhile, the existence of organic compounds will reduce the biological stability of drinking water and lead to the secondary reproduction of microorganisms in the pipe network. Therefore, it is important to reduce the content of organic pollutants in drinking water. Conventional water treatment process has low removal efficiency for organic pollutants, so it is imperative to seek economic and efficient treatment technology. On the basis of giving full play to the advantages of ozone oxidation to remove organic matter, ozone catalytic oxidation technology can induce the formation of highly oxidizing hydroxyl radical (-Oh), which can effectively remove trace organic pollutants that are difficult to degrade in water and reduce the content of ozone oxidation by-products.

The effect of the amount and adding method of activated carbon on smoke emission of cigarettes was investigated. It was found that the filtration efficiency of ternary compound filter was higher than that of binary compound filter under the influence of plasticizer when the amount of activated carbon was constant. With the increase of the amount of activated carbon, the filtration efficiency of the two kinds of composite filters increases. The effects of the amount of activated carbon on the filtration efficiency of the compounds with different volatiles are different. The effects of the amount of activated carbon on the filtration efficiency of the isomers are similar due to their close molecular weight and boiling point. When the dosage is small, the competitive adsorption is easy to occur. The adsorption amount of refractory components such as acetaldehyde is small, and the competition can be reduced by increasing the dosage. The filtration efficiency of refractory components shows an obvious upward trend with the increase of the dosage. It was found that the contents of volatile compounds and flavor components were related to the type of cigarettes and the amount of tar. The contents of volatile compounds and flavor components were higher in the flue-cured cigarettes than in the mixed cigarettes, and higher in the high tar cigarettes than in the low tar cigarettes. The types of fragrance components in smoke of different types of cigarettes are basically the same, but there are great differences in content. The contents of furfural, furfuryl alcohol, maltol, 5-hydroxymethylfurfural, linolenic acid, methyl linolenic acid, linoleic acid, methyl palmitate and other components in flue-cured cigarettes were significantly higher than those in mixed cigarettes. This is related to the higher carbohydrate content in flue-cured cigarettes. Mixed-type cigarettes contain high content of 3-methylpentanoic acid and nitrogen heterocyclic compounds such as cotinine, ho ah, and methamine due to their formulations of burley tobacco and spice tobacco. The filtering law of activated carbon for different types of cigarettes is basically the same, that is, the filtering efficiency is related to the properties of compounds, especially with the molecular weight and boiling point of compounds. The filtration efficiency of activated carbon on flue-cured cigarettes was lower than that of mixed cigarettes.

The maintenance sewage contains a large number of complex biodegradable substances, biodegradability is poor, for many years mainly rely on fresh water dilution treatment and combustion furnace treatment, but these two methods are low efficiency and high cost, so it is necessary to develop new wastewater treatment methods.www.chinactivecarbon.com   Although we have studied the upflow anaerobic sludge bed reactor (UASB) for the treatment of high concentration sewage of the natural gas purification plant, the start-up test results of 133 days show that the effluent COD removal rate is only about 40% when the influent COD is 6000mg/L, and the treatment effect is not good. Therefore, it is of practical significance to explore and seek an effective pretreatment method.gold adsorption on activated carbon  In this paper, Fenton oxidation and activated carbon adsorption were combined to pretreat the wastewater from natural gas purification maintenance, in order to improve the subsequent operation efficiency of UASB. This experiment by orthogonal test to determine the Fenton reagent oxidation first preliminary operating conditions, on this basis, carries on the single factor analysis method, the main factors influencing the Fenton reagent treatment effect for each study, investigation of its influence on wastewater COD removal rate, the results show that Fenton oxidation method the optimum operating conditions for natural gas purification overhaul wastewater treatment: HO2 dosing quantity 0.3 mol/L, n (HO)/n (Fe) = systematically, initial pH = 3, reaction temperature 70 ℃, reaction time, 40 min. Under these conditions, the COD removal rate reached 78.6%, the BOD /COD value increased from 0.168 to 0.353-0.403, and the biodegradability was greatly improved. If Ho is added in three times and the interval time is 10min, the COD removal rate will increase from 78.6% to 80.3%. Therefore, it can be seen that H0: batch addition will further improve the reaction effect. After Fenton oxidation treatment, wastewater and activated carbon adsorption, this topic activated carbon adsorption experiments using single factor method, examines different PH, activated carbon adsorption dosing quantity and the influence of adsorption time of wastewater COD removal rate, the results show that after Fenton oxidation treatment without having to adjust PH value, according to the 20 g/L after adding the activated carbon reaction 3 h at room temperature, COD removal rate was 47.3%,, BOD/COD value of 0.438 to 0.625. The research in this paper has laid a theoretical foundation and provided an experimental basis for the practical application of Fenton oxidation and activated carbon adsorption in the pretreatment of natural gas purification maintenance wastewater in UASB reactor.
