The Combined Process Method and Unit Equipment using Ozone-Electrolysis/Semiconductor Catalysis for Treatment of Non-degradable Waste

摘要

The present invention, advanced oxidation treatment with OH radical: I by (AOP Advanced Oxidation Process) ozone for the treatment of biodegradable waste liquid-electrolyte / semiconductor composite device, and as a catalyst for its use, the waste water from I to generate the OH radical is much more than the conventional method for decomposing pollutants AOP decomposition, the waste water treatment efficiency and relates to a device for improving the economic efficiency. More particularly, the present invention is the electrolytic bath, the electrolytic bath is filled to handle the power, waste water for supplying a current to the electrode, the electrode comprising a cathode and an anode catalyst is, and for supplying the electrolytic bath ozone I comprising the ozone generator the ozone for the treatment of biodegradable waste-electrolysis / catalyst complex in the device, diffusion is provided in the electrolytic tank bottom to refine the ozone bubbles that maximizes contact of the waste water with ozone and seats; Wherein the catalyst is a tray filled with these trays are stacked in multiple layers monolayer catalyst support structure; The catalyst that each tray is filled the cathode and the anode to be installed on each end that sapchak; And be made of a mixture of ozone and the effluent continues to flow, equalizing space present in the upper semiconductor catalyst layer filled in each stage tray; Circulation system that enables oxidation decomposition treated waste water can be recycled at the bottom portion to the reaction vessel as necessary; And the uppermost layer of the catalyst support structure is a single-layer ozone treatment for recalcitrant waste liquid comprising the activated carbon is packed in the mesh net of the basket form - is for the electrolysis / catalyst composite device
