Test of Potassium Permanganate Cooperating with Ultrasonic and Air to Treat Micro-polluted Water of Low Temperature

The paper uses potassium permanganate as oxidation and coagulation cooperating with ultrasonic and air to treat micro-polluted water of low temperature.There are 4 methods,including potassium permanganate cooperating with ultrasonic and air(PCUA),ultrasonic,potassium permanganate and permanganate cooperating with ultrasonic.The test indicates that oxidizing and coagulating result of PCUA is best,which can remove organic matter in water,COD_(Mn),by 16.9% by oxidation,and by 48.82% by oxidation and coagulation.Assist-coagulating result of PCUA for turbid and color is a little bit lower than potassium permanganate alone.The former rate for the turbid is 74.57%,for the color is 64.1%;the latter rate for the turbid is 86.67%,for the color is 76.19%.So PCUA can treat COD_(Mn),the organic matter,from water.
