Study On Organic Industrial Wastewater Degradation By Advanced Catalytic Oxidation Method

In recent years, more researches are carried out on refractory persistent organic mathods about pollutant and waste water treatment at home and abroad, one senior oxidation method has great potential and unique advantages. Compared with other treatment methods, advanced oxidation method has the following characteristics: â‘ A large amount of reactive hydroxyl radical HO ?, which after oxidation of fluorine,as an intermediate product of the reaction, chain reaction can be induced as the reason.â‘¡HO ? No selectively react directly with the wastewater pollutants which degrade into carbon dioxide, water and harmless salt and this process does not produce secondary pollution; â‘¢ Since it is a physical- chemical treatment process, it is easy to be controlled to meet the processing needs, or even degradation of pollutants stage10-9; â‘£ As a separate treatment, also to match with other processes, such as biological treatment and after the treatment, it can reduce processing costs. Therefore,it is imperative for wide scope, less investment, energy efficient ways. The technology is almost all wastewater treatment, and the device is simple, small footprint, consume less(can use solar energy) which is very suitable for our country.Apart from high Efficiency, there are many benefits, such as energy saving, Low operating costs, and wide applicability, fast, not only with the advanced oxidation processes(AOPs) features. And saving energy is appropriate with Chinese national conditions, practical and effective method for treating wastewater and this technology amplifies experiments and research development of advanced catalytic oxidation of the corresponding processing device with high research value and application value,will make the bottleneck restricting water- high running costs can be completely resolved. This technique can be used for water quality in urban sewage, industrial wastewater and the purification of rivers, lakes and depth of processing water reuse,the market prospect is very broad, it will generate significant economic, social and environmental benefits.
