Advanced oxidation equipment and sewage treatment system

Abstract

The invention belongs to a sewage treatment system. A Fenton method is high in reagent cost and sewage treatment expense when being used for treating sewage and thus operating cost is high. The invention provides advanced oxidation equipment, wherein a pull rod is in perforated connection with an insulating sleeve (2), the pull rod (1) and the insulating sleeve (2) are integrally in perforated connection with an electrode plate (7), the pull rod (1) fastens the electrode plate (7), an insulating gasket (3) is in perforated connection with the insulating sleeve (2), a first connector (4) is fastened and connected with the insulating sleeve (2), a fixing bottom angle (5) is fixedly connected with the first connector (4), a power source connector (6) is fixedly connected with the electrode plate (7), and the electrode plate (7) is covered with a conductive manometer film through which only H<+> can pass. The invention discloses the sewage treatment system composed of the advanced oxidation equipment. The sewage treatment system has the advantages of low yield of sludge, low operating cost and simplicity and convenience in operation.

Description

technical field [0001] The invention belongs to a sewage treatment system, in particular to a sewage treatment combined process using advanced oxidation equipment. Background technique [0002] With the rapid development of our country's social economy, a large amount of sewage and wastewater are inevitably produced, which leads to serious environmental pollution and ecological damage. Traditional treatment methods cannot completely eliminate degradation pollutants, and are likely to cause secondary pollution, with narrow application range and high energy consumption. In recent years, the use of advanced oxidation methods to treat sewage and wastewater has received widespread attention. [0003] The advanced oxidation method will produce highly oxidizing OH, and OH reacts quickly with most organic matter, odorous substances, and heavy metal substances, and has a fast removal rate and high efficiency for organic matter; it can quickly oxidize polluted sediment, remove Odor,...

AI Technical Summary

Problems solved by technology

However, the Fenton method also has the problems of requiring low influent concentration, high cost of chemicals, large amount of mud, and being easily affected by experimental conditions, and hydrogen peroxide has strong oxidizing properties. If the protection is not good, it will corrode the human body to a certain extent. Sulfuric acid Ferrous iron also has certain corrosiveness, therefore, the application of Fenton's method in actual engineering is subject to certain restrictions
