 BestBath said Fenton oxidation method is the use of catalytic chain reaction between Fe and H2O2 generate a strong oxidizing · OH to deep oxidation of toxic and refractory organic compounds in order to achieve the purpose of the removal of contaminants. The law in dealing with biodegradable or general chemical oxidation of organic waste to be ineffective, with simple equipment, mild reaction conditions, easy operation, high efficiency and other advantages. Left Chen Yan and other studies have shown that, Fenton oxidation can oxidize phenolic compounds in coking wastewater mechanical degreasing who to contact, thus greatly reducing the COD of wastewater. Bi strong effects of stainless steel and graphite as the anode gas diffusion electrode on a cathode Fenton system of semi-coke wastewater COD removal. The results showed that after treatment by electroporation Fenton, blue carbon wastewater COD removal rate can reach 78.62%. Fenton oxidation blue carbon wastewater COD removal obviously, but the removal of ammonia nitrogen is limited and subject associated with other methods to improve the wastewater biodegradability.吕永涛 other studies with Fenton oxidation - stripping blue carbon wastewater pretreatment, the results showed that under optimum conditions, COD, chroma and ammonia nitrogen removal rate reached 95.72%, 95% and 88%, B / C to 0.55, greatly improving the wastewater biodegradability. Fenton oxidation can degrade a variety of toxic and hazardous machinery refractory organic pollutants in addition to oil, but the reaction must be carried out under acidic conditions (pH between 3 to 5 best), the solution after the reaction and the need to consume large amounts of lye and the need to consider the disposal of iron clay. With phenol-based high concentration organic wastewater mechanical BestBath about coking wastewater in the production of coke, gas, tar and other coking products generated in the process in addition to oil to find any required pretreatment, biological treatment and depth of processing only after discharge [1]. Adsorption method can effectively remove a variety of contaminants in wastewater, treated water quality is good and relatively stable [2]. Calcium silicate is a kind of industrial waste fly ash produced after extraction of high aluminum, which is microscopic honeycomb structure, layered, curly layered, internal and surface porosity due to particle characteristics and development [3], which adsorption of pollutants has certain properties. But the direct use of calcium absorption contaminants adsorption capacity is limited, higher processing costs and other issues. Studies have shown that the modified calcium silicate after mechanical degreasing what brand, the adsorption performance can be improved, but some modification methods to improve the absorption effect and also increase the cost of water treatment. S. Wang et al. [4] with a base joint action by the ultrasonic modification treatment of fly ash, fly ash compared to the unmodified, the adsorption capacity of methylene blue was increased from 0.006 mmol / g to 0.012mmol / g. It uses ultrasonic cavitation caused by energy and mechanical effects on calcium modified its structure and surface chemistry changes, in order to improve their absorption capacity, and studied its effect on the absorption of coking wastewater.
