Multifunctional packed column for waste water treatment
This utility model disclosed a multifunctional packed column for waste water treatment, which is made up of the column, packing supporting device, packing compacting device, liquid distribution device, liquid collection and redistribution device, demister, special activated carbon packing device, and skirt support. The column, installed on the skirt support, is equipped with air inlet and outlet, water outlet and inlet, and installation holes. The special reactivated carbon packing device is mountered on the packing supporting device and compacted by the packing pressing device. The liquid collection and redistribution device is located in between the two layers of the special activated carbon packing. The liquid distribution device is connected to the water inlet. Due to large liquid contact area, this utility model achieves better blowing down effect, which may catalyze oxidation for many reducible substances, and the oxidant is the oxygen in the air, so, it is cheap and available. The special activated carbon packing may improve the mass transferring effect of the two phases of gas and liquid, as the liquid phase has good wettability on its surface and is able to adsorb and recover valuable materials, creating favourable economic benefit. It is simple in structure, easy to operate, energy saving, and no secondary pollution.
