好氧生物处理法是利用好氧微生物（包括兼性微生物）在有氧气存在的条件下进

Aerobic biological treatment using aerobic microorganisms (including facultative organism) in biological metabolism carried out under the presence of oxygen to degrade organic matter, stabilized, treatment harmless. Microorganisms using organic pollutants present in the water as substrate for the aerobic metabolism, after a series of biochemical reactions, gradual release of energy, low energy bit inorganic eventually stabilized, achieve sound requirements, or to return the natural environment further processing. Sewage treatment works, the aerobic biological treatment activated sludge and biofilm two categories. <br>Keywords aerobic biological treatment, activated sludge, biofilm

Aerobic biological treatment is a method of using aerobic microorganisms (including co-organisms) to carry out biometabolism under the condition of the presence of oxygen to degrade organic matter, so that it is stable and harmless treatment. Micro-organisms use organic pollutants present in water as the substrate for aerobic metabolism, after a series of biochemical reactions, step-by-step release of energy, and finally with low energy level inorganic matter stabilized, to achieve the requirements of harmless, in order to return to the natural environment or further treatment. In sewage treatment project, aerobic biological treatment method has two major categories: activated sludge method and biofilm method.<br>Keywords Aerobic biological treatment method, activated sludge method, biofilm method

Aerobic biological treatment is a kind of treatment method which uses aerobic microorganisms (including facultative microorganisms) to carry out biological metabolism in the presence of oxygen in order to degrade organic matters and make them stable and harmless. Microorganisms use organic pollutants in water as substrate for aerobic metabolism. After a series of biochemical reactions, energy is released step by step. Finally, inorganic substances at low energy level are stabilized to meet the requirements of harmless treatment, so as to return to the natural environment or further treatment. In the sewage treatment engineering, there are two kinds of aerobic biological treatment methods: activated sludge method and biofilm method.<br>Key words: aerobic biological treatment, activated sludge, biofilm<br>
