城市污水处理厂污泥的好氧处理研究

为了实现污泥的稳定化、减量化和无害化,对城市污水处理厂的浓缩污泥和厌氧消化污泥进行了好氧处理试验研究.试验结果表明,污泥好氧处理使污泥中有机物质含量降低,臭味减小.厌氧污泥经好氧消化处理后,一方面使污泥得到稳定化和减量化;另一方面,可以把污泥中的致病菌杀死.污泥经好氧消化后沉降性能有明显提高,絮凝剂的加入使其脱水性能也得到一定的改善.

Research on Aerobic Treatment of Sludge in Urban Sewage Treatment Plant

In order to realize sludge stabilization, reduction and innocuity, an experimental research on the aerobic treatment of thickened and anaerobic digestion sludge in urban sewage treatment plants was carried out. The results show that the aerobic digestion may reduce the content of organic substances and the sludge odor. The aerobic digestion of anaerobic sludge is performed, the sludge stabilization and reduction are reached, and the germs in sludge can be killed. The sludge settleability is enhanced after aerobic digestion. The addition of flocculant improves the dewaterability.
