MULTISTAGE DAF-ADVANCED OXIDATION SYSTEM |
摘要 |
<p>A multistage dissolved air flotation and advanced oxidation (MDAF-AO) system/method with multi-functions in oil recovery, solids removal, emulsion breaking, and advanced oxidation. Influent, with oil and suspended solids, enters a first stage for oil recovery includes a gas ionizer and an air dissolving pump. A second stage includes of two coagulation/flotation compartments connected in serial to enhance solids removal efficiencies. Micro air bubbles are created by air dissolving pumps in each compartment. A third stage is for the emulsion breaking unit to further remove or recover the emulsified oils. A fourth stage includes advanced oxidation by using ultraviolet (UV) and hydrogen peroxide to oxidize and disinfect the bacteria and microorganisms.</p> |
