    1.1Wastewater Treatment Technology---UASB-A2/O Treatment Process
    译：污水处理技术-UASB-A2/O处理工艺
    1)Principle of anaerobic treatment
    译：厌氧处理原理
    Organic matter in the wastewater is degraded and treated through two steps of biochemical reaction by the facultative anaerobic bacteria such as acid-formation bacteria and the strictly anaerobic bacteria. In the first acid fermentation step, the organic matter is degraded into low-grade fatty acid, carbon dioxide, hydrogen and so on. In the next step for methane fermentation, the low-grade fatty acid is degraded and methane gas is produced. Through the UASB process, the acid fermentation and methane fermentation proceed correlatively both in the equalization tank and UASB reactor to degrade and remove organic substances.
    译：污水中的有机物质经半需氧菌两级生化反应后被降解和处理，使用的半需氧菌包括酸形成菌和严格意义上的厌氧菌。在最初的酸发酵工序，有机物质被降解为低度脂肪酸、二氧化碳、氢气等物质。下一道工序进行甲烷发酵，低度脂肪酸被降解，产生了甲烷气体。通过UASB工艺，酸发酵和甲烷发酵在平衡槽内交互进行，UASB反应器进行降解并转移有机物质。
    2) Granular Sludge
    译：颗粒状污泥
    Organic matter is degraded by utilizing granular sludge self-granulated to1-3mm diameter by anaerobic bacteria whose dominant is Methanothrix. This granular sludge is superior to others in having greater sedimentation velocity (20-40m/h) and very high organic degrading activity. These enable the equipment to be compact and economical.
    译：有机物质的降解采用颗粒状污泥，可以采用厌氧菌自行分散为一到三毫米直径的粒子，厌氧菌的主要物质是Methanothrix。这种颗粒污泥的好处在于沉降速度更快（20-40m/h），有机降解能力强。这些优点提高了设备效率，降低了生产成本。
    3) UASB reactor
    译：UASB反应器
    The following figure shows the structure of the UASB reactor and the general view of the installation. The reactor consists basically of influent water distribution device, reaction section (sludge zone) and three-phase separator. Wastewater entered from the influent water distribution device is distributed uniformly in the reactor, moves up the reaction section slowly and comes in contact with granular sludge where organic matter is degraded. The treated water is discharged from the reactor after the gas and fine granule are removed by the three-phase separator.
    译：下图说明了UASB反应器的结构以及安装流程。该反应器主要包括流入水分配设备、反应装置（污泥区域）和三级分离器。进入流入水分配设备的污水被统一分配进入反应器，缓慢流入反应区，并与有机物质降解所在的颗粒污泥区接触。经过处理的水经三级分离器滤除气体和微小颗粒后，进入反应器。
