AEROBIC WASTEWATER TREATMENT SYSTEM OF ORGANIC AND INORGANIC MATTER

摘要

PURPOSE: An aerobic wastewater treatment system of organic and inorganic matter is provided, which can supply much oxygen bubble of 0.5-10m by oxygen generator(5) without any air sparger, remove extremely fine particles through fixed mixers(9) in which baffles are set and provide vegetation community place for microorganism, so that can remove suspended organic and inorganic matter contained in wastewater. CONSTITUTION: The system comprises a primary treater(3), a bellow pipe, three secondary treaters, an ultraviolet ray irradiation device and a discharge pipe. The primary treater(3) that is connected to primary settling basin(1) consists of four chambers, oxygen generators(5a,5c,5d,5e), venturi pipes(7a,7d,7e) and fixed mixers(9a,9b,9c,9d,9e). Each oxygen generator takes in air and water and further mixes with air at venturi pipe with air taken through the other air inlet and at the fixed mixer formed by many baffles set in zig zag form. The unit mixing system is set at the all chambers in same manner. At the bellow pipe, microorganism biologically decomposes inorganic or organic matter. The secondary treaters are formed in same structure as the primary treater(3).
