“…H 2 O 2 concentration was determined by the DMP (2, 9-dimethyl-1,10-phenanthroline) method (Kosaka et al, 1998). (Gunten, 2003;Rosenfeldt et al, 2006;Tizaoui et al, 2007;Wu et al, 2007;Bandyopadhyay and Chattopadhyay, 2007;El Diwani et al, 2009). Therefore, these abnormal results could be due to interference by H 2 O 2 since overestimation was not observed during treatment with ozone alone or O 3 /UV.…”

It is known that hydrogen peroxide interferes with chemical oxygen demand analysis by consuming oxidation agents such as potassium dichromate, thus leading to overestimation of the chemical oxygen demand measurements. The objective of the study was to investigate the effects of hydrogen peroxide interference and to determine true chemical oxygen demand values on interpreting treatment performance during ozone-based advanced oxidation of livestock wastewater in which hydrogen peroxide concentration and chemical oxygen demand values are dynamically changing. According to the chemical oxygen demand monitoring data, chemical oxygen demand values were always higher than the initial chemical oxygen demand load when hydrogen peroxide was involved and the treatment performance with ozone alone or ozone/ultraviolet was better than with coupled hydrogen peroxide. The extent of overestimation was proportional to the remaining hydrogen peroxide concentration and the average overestimation ratio in livestock wastewater was in the range of 0.50~0.58 mg per 1 mg of hydrogen peroxide, depending upon the quality of the wastewater treated. True chemical oxygen demand values were estimated by correlating the extent of overestimation with the remaining hydrogen peroxide concentration during treatment. The extent of overestimation decreased to zero gradually as the amount of hydrogen peroxide also approached zero as oxidation proceeded. The corrected chemical oxygen demand values indicated underlying tendency of oxidation, which could not be seen in the original chemical oxygen demand monitoring data. Application of ozone/hydrogen peroxide was more efficient for reducing chemical oxygen demand than ozone alone, as was ozone/hydrogen peroxide/ultraviolet compared to ozone/ultraviolet. When coupled with ozone, ultraviolet irradiation was more efficient than hydrogen peroxide for decreasing chemical oxygen demand during treatment of livestock wastewater.

“…As previously mentioned, ozonation as a single process was not considered as very effective (COD reduction is about 15-50%) [15,16,[24][25][26][27][28][29]. Thus, most researchers used ozonation process as pretreatment before biological treatment or tertiary treatment prior to discharge in the environment.…”

“…In such a process, in fact, under acidic condition, a Fe 2+ /H 2 O 2 mixture produces •OH radicals in a very effective way [49]. Tizaoui et al [27] estimated the treatment cost of O 3 /H 2 O 2 system was about 2.3 US$/kg COD. Kurniawan et al [17] showed that the treatment coat of leachate using ozone-GAC adsorption varies between US$ 2 and 4 per m 3 of the treatment effluent.…”

In most countries, sanitary landfill is nowadays the most common way to eliminate municipal solid wastes (MSWs). However, sanitary landfill generates large quantity of heavily polluted leachate, which can induce ecological risk and potential hazards towards public health and ecosystems. The application of advanced oxidation processes (AOPs) including ozone-based oxidation, Fenton oxidation, electrochemical oxidation, and other AOPs to treatment of landfill leachate was reviewed. The treatment efficiency in term of chemical oxygen demand (COD) of various AOPs was presented. Advantages and drawbacks of various AOPs were discussed. Among the AOPs reviewed, Fenton process should be the best choice, not only because it can achieve about 49∼89% of COD removal with COD ranging from 837 to 8894 mg/L, but also because the process is cost-effective and simple in technological aspect, there is no mass transfer limitation (homogeneous nature) and both iron and hydrogen peroxide are nontoxic.
