摘　　要：用铁氧体法处理含铬和镉废水， 在ｐＨ 值为１２ 、温度为７０ ℃、滴加适量双氧水时， 即可得磁性较强的铁氧体， 同时，被处理后的废水中铬和镉的含量分别降低至０－００８ ｍｇ／Ｌ 和０－０４１ ｍｇ／Ｌ， 均达到排放标准。The wastewater containing chromium and cadmium was treated by means of producing ferrite. When the pH was controlled at 12 and temperature at 70℃,ferrite of strong magnetism could be obtained by adding appropriate content of H 2O 2.The concentrations of chromium and cadmium in treated wastewater could be decreased at magnitudes of 0 008mg/L and 0 041mg/L,respectively, which were all below the drainage standards.
