The remediation of VOC contaminated soil and underground water has been an social problem nationwide. We recently developed a new water treatment system for VOCs abatement by using a combination technology of aeration and combustion. In this system, VOC contaminated water is at first aerated to get VOCs out of water. The VOCs containing air is premixed with city gas and then burned. Combustion heat is used to warm the untreated water, so that the water is aerated around the temperature of 40℃. Comparing with the exiting treatment method of activated carbon adsorption, this system has higher VOCs removal rates without generating industry wastes. The burned gas was analyzed to check the concentration of dioxins and unburned VOCs.
