Adding appropriate chemical reagents will play the role of catalytic oxidation [73], and these chemical reagents will also increase the active point of activation reaction, which is conducive to

the development of activated carbon pores.

Now at home and abroad the main research work is mainly the following aspects: a, additive in the functional mechanism of manufacturing activated carbon energy gao jun of China university of mining mechanism of additives in the manufacturing activated carbon made detail [4, pointed out that: the catalyst in the carbonization stage prompted carbon the destruction of the molecular structure of aromatic raw materials, to "structure" of disordering, provides a good initial activation reaction conditions, is an important factor to improve the activation of activated carbon pore. In the process of activation, potassium to strengthen the directionality of the pore, thereby reducing the unnecessary on ignition, and accelerated the process of pore forming,https://www.activated-carbon-pellets.com 

And pore distribution is given priority to with microporous activated carbon; refractory in the catalyst to ash content of SiO2 and Al, 03, etc, into acid soluble potassium nepheline chemical compounds such as magnesium and calcium silicon stone is the key to improve pickling deliming rate factor b and additives on the activated carbon adsorption properties, pore structure and pore size distribution - adding different additives. The influence of the activated carbon: c, chemicals for coking products. 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.carbon activated company 

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.
