白酒工业废水中活性污泥性能指标的测定

The Determination of Activated Sludge Performance Indicators in Chinese Spirits Industry Waste Water

活性污泥是人工培养的生物絮凝体,它是由好氧微生物及其吸附的有机物组成的,具有吸附和分解废水中的有机物的能力,显示出生物化学活性。主要介绍白酒工业废水中好氧活性污泥性能指标的测定方法。活性污泥的性能指标一般有污泥沉降比(SV)、混合液悬浮固体浓度(MLSS)、污泥体积指数(SVI)、混合液挥发性悬浮固体浓度(MLVSS)、污泥灰分、污泥负荷(Ns)。

The activated sludge is artificial cultivation of biological floc, it is composed of aerobic microorganisms and adsorption of organic matter, with adsorption and decomposition of organic matter in wastewater and biological activity. This paper mainly introduces the determination method of aerobic activated sludge performance index in Chinese spirits industry waste water. The performance of activated sludge are generally sludge settling ratio（SV）, mixed liquor suspended solids concentration（MLSS）, sludge volume index（SVI）, mixed liquor volatile suspended solids concentration（MLVSS）, sludge ash, sludge load（NS）.
