The new oxide flocculation reactor (OFR) technique for wastewater treatment was successfully developed. The OFR is filled with the high effect non toxic special material

catalyst and other auxiliary ingredients between the main electrodes.Under physical chemical optimal condition

inorganic and organic contaminants in wastewater are rapidly removed by subjecting to oxidation reduction

coagulation

adsorption

complexation

replacement and so on in the OFR Two types of organic pollutants

phenol and chloral hydrate as the objects of the catalytic degradation mechanism with the OFR technique were studied The results indicate that is actually the oxidation of hydroxyl radical (·OH) which can be produced rapidly from the first yielded H2O2 in the OFR·OH in the treating process of the OFR with the method of spin trapping ESR was discovered Finally

the treatment for various wastewater(domestic sewage

printing and dyeing wastewater

pharmaceutical industry wastewater ) with the OFR were investigated
