摘要： This invention relates to processes for the removal of phosphorous from aqueous waste streams comprising phosphorus-containing compounds produced in the manufacture of glyphosate, in order to meet and typically exceed environmental regulations. More particularly, various embodiments of the present invention relate to the removal of phosphorous-containing compounds utilizing biological treatment system(s), oxidizing agent(s), and/or precipitant(s). The processes of the invention are also applicable to the removal of phosphorous compounds from phosphorous-containing waste streams other than those waste streams resulting from the manufacture of glyphosate.
