Abstract

The invention discloses an integrated sewage treatment unit and a method. The unit comprises a membrane biological reaction processor, an ozone generation system and a UV decomposition processor comprising at least one UV light source. A combined treatment method is employed to combine sewage separation by membrane and degradation of organic matters by activated sludge, and then the sewage is subjected to high-grade oxidation by hydroxyl free radicals. The integrated sewage treatment unit and method provided by the invention not only can remove macro-molecular organic matters, virus and microbes in sewage through aeration treatment by an aeration unit in the membrane biology reaction processor and degradation treatment by aerobic microbes in biological activated sludge, but also can generate hydroxyl free radicals with extremely strong oxidization through ultraviolet ray irradiation on gas-liquid mixture of ozone and water. Hydroxyl free radicals use extremely strong oxidization to thoroughly decompose organic matters in water, further remove microbes, and to generate carbon dioxide and water, so as to realize the purpose of excellent deodorization, decoloring, disinfection and removal of harmful substances including COD, BOD, ammonia, nitrogen and phosphor, etc.

Description

technical field [0001] The invention relates to a sewage treatment device and method combined with various sewage treatment technologies, in particular to the use of a membrane bioreactor (Membrane Bio-Reactor, referred to as MBR), and an advanced oxidation process (Advanced Oxidation Processes, referred to as AOP technology), etc. The invention relates to a sewage treatment method carried out by combining various sewage treatment technologies, and belongs to the technical field of water pollution treatment. Background technique [0002] Environmental protection of water resources is an issue of widespread concern in today's society. For a long time, people have used different technologies and methods to treat sewage. There are three types of commonly used sewage treatment methods. First, physical treatment methods such as grille, filtration, sedimentation, air flotation, and reverse osmosis are used for water pollution treatment; second, chemical treatment methods such as ...
