The development of a simple, low-cost method for making wastewater polluted with dioxins⁄furans (dioxins) harmless is one of the important assignments in a waste incineration and a sewage disposal plants. The purpose of the present study is basically to develop a simple removal method of dioxins in wastewater and to evaluate a basic removal ratio of dioxins. Removal method of dioxins in wastewater has been investigated by using fluidized bed with polyolefin particles, which have adsorption ability for fly carbonaceous matters (C∗) including almost all dioxins. The fly C∗ including almost all dioxins in wastewater can be removed by adsorbing on polyethylene (PE) particles. The removal ratio of dioxins (R_DW) from wastewater by using fluidized bed with PE particles is estimated from the following equation: R_DW (%) = 100×{ 1−exp(−8×10⁻⁴•S_S•t_C)}, where S_S (cm²⁄cm³) is a specific surface area of particles, and t_C (s) is a contact time between particles and wastewater.
