In this 55 pages Master’s thesis on subject „Investigation of advanced oxidation factors influence on last stage industrial waste water treatment”, advanced oxidation processes which do not require any additional reagents are reviewed. In this paper, we investigate advanced oxidation factors, such as ozone, UV radiation, TiO2 catalyst, pH influence on last stage industrial waste water treatment efficiency. We evaluate relative total organic carbon degradation speed. This work tasks are scientific literature analysis, evaluate ozone and UV radiation effect on industrial waste water treatment efficiency, investigate if synergetic ozone, UV radiation and catalyst effect can be achieved, evaluate pH influence on industrial furniture waste water treatment efficiency and evaluate relative waste water treatment efficiency in open system. Master’s thesis consists of these parts: introduction, overview of literature, methodical part, results, conclusions. It has been found that the most efficient method for total organic carbon removal was using of ozone, UV radiation and TiO2 catalyst combined, after 3 hours it reached 99,35 % efficiency. A trend was observed that treatment of these specific waste water was more efficient when their pH was acidic (100 % after 3 hours), compared with neutral (99,07 % after 3 hours) and caustic (90,34 % after 3 hours). However, using this method pH influence on waste water treatment efficiency is minor. While investigating relative waste water treatment efficiency in open system it was found that waste water treatment is more efficient if total organic carbon concentration does not exceed 20 mg/L. 1,219 mg∙L-1∙min-1 degradation of total organic carbon was achieved while using ozone, UV radiation and TiO2 catalyst in parallel. |
