摘要/Abstract

摘要：

城市污水处理厂产生的污泥按照来源的不同可以分为初沉污泥和剩余污泥，总量约占处理水量的0.3%-0.5%(以含水率97%计)。国内外对污泥厌氧水解产酸的研究多集中于使用初沉污泥或初沉和二沉污泥的混合污泥。污泥经过水解发酵后，既能产生生物除磷过程所需的有机酸，又减少了剩余污泥对环境的污染。将城市污水厂污泥生物转化为挥发性有机酸并用于强化生物除磷丰富了生物除磷和污泥处理与资源化等研究内容，同时对于许多南方污水厂碳源少的情况也有着一定的实际应用价值。

关键词: 污泥发酵产酸, 强化生物除磷, 挥发性脂肪酸

Abstract:

There are mainlytwokinds ofsludge in the municipal wastewater treatment plant, i.e., primaryand secondary sludges. They account for 0.3%-0.5% of the treatment wastewater quantity, if the water containing ratio of sludge is 97%. The studies on the fermentation of sludge in the literature mainly focus on the treatment of the primary or its mixture with excessive sludge. After hydrolysis and fermentation of the sludge, the VFAs that are needed for the enhancing biological dephosphorization are produced, and at the same time, the pollution of sludge to the environment is reduced. It specially makes sense that the technology of sludge acidogenesis applied to the southern municipal wastewater treatment plant where the quantity of the carbon source is low.

Key words: fermentation and acidogenesis of sludge, enhanced biological dephosphorization, volatile fatty acids
