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. It is a kind of water treatment method with great prospect.activated carbon for gold recovery  Laboratory studies have shown that ceramic honeycomb activated carbon catalytic ozone oxidation technology and removal of trace organic matter in water has more obvious advantages, but the catalytic oxidation and active carbon process characteristics to be in-depth study, therefore the pilot was investigated through honeycomb ceramic catalytic ozonation and activated carbon catalytic ozonation and activated carbon filter combination process operation characteristics. activated carbon wholesale

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.

In domestic has been eliminated. Specific surface area test unified the multi-point BET method at home and abroad, specific surface area measurement standards are developed at home and abroad is based on BET test method, please see our national standard (GB/T 19587-2004) - gas adsorption BET principle of solid material specific surface area measurement methods. Specific surface area testing is actually the more time-consuming jobs, as the adsorption capacity of sample is different, some sample testing may need to spend the whole dayTime, if the test process is not fully automated, the tester can not leave at any time, and should be highly focused, observe the dashboard, control the knob, a little careless will lead to the failure of the test process, which will waste a lot of valuable time of the tester.activated carbon for gold recovery  F - Sorb 2400 specific surface tester is really able to BET method detection instruments (both direct comparison method), the more important F - Sorb 2400 specific surface tester is by far the only specific surface area of the fully automated intelligent testing equipment, the test results with the international high consistency, the stability is very good also, at the same time reduce the human error, improve accuracy test results. activated carbon wholesale
