Abstract

A kinds of Methamidophos wastewater was pretreated by acidification and Fenton oxidation process, and the results demonstrated that, at pH value of 2.0 and reaction temperature 100degC, a removal efficiency of TOC and sulfide of was reached to 18.33% and 90.7% respectively, at pH value of 4.0, n(H₂O₂):n (Fe²⁺) of 30 and 3.0% of H₂O₂, that of TOC was reached to about 24.3%, while at addition of 20% Ca(OH)₂ and pH value of 11.0 to 12.0, total of inorganic phosphorus was precipitated completely from the wastewater.
