Abstract

Using microwave technology enhanced flocculation treatment of oilfield wastewater containing polymer .Chose the wastewater COD removal efficiency as an evaluation index, investigated four kinds of flocculants, such as AlCl3, FeCl3, PAC, PAF in the microwave irradiation and no microwave irradiation two types of test flocculation conditions, and offered to fly ash as adsorbent adsorption-microwave flocculation combined process to enhance wastewater treatment effect, with no secondary pollution can be achieved by waste. The experimental results show the effect of microwave has a significant promote to ferric flocculants’ flocculation process, and fly ash adsorption-microwave process is better than simple microwave flocculation process, in the solid-liquid ratio of 1: 100, stirring speed 200 r•min-1, the adsorption time 30min, microwave flocculation time 90s, the conditions under microwave irradiation power of 400W, COD removal rate can be increased by 25%.
