剩余有机污泥“零排放”工程性试验

采用活性污泥法处理有机废水产生的剩余污泥 ,一般较难处置 ,缺少有效的处理方法。通过实验室试验成功的基础 ,经过为期 1a的现场运行考核 ,采用常温兼氧酸化水解—生物反应的新工艺 ,解决了有机废水处理过程中产生的剩余污泥 ,实现了污泥“零排放”。将污泥处理与废水生物处理组合在同一系统 ,不仅操作管理方便 ,而且可提高原处理系统的CODCr达标率约 5%～ 1 5%。该工艺特别适用于含氮有机废水处理系统 ,可使NH_3 -N进一步脱氮去除。

ENGINEERING TEST OF "ZERO DISCHARGE" OF RESIDUAL ORGANIC SLUDGE

It is generally difficult to treat the residual sludge produced by treatment of organic wastewater through activated sludge process.Based on the successful laboratory tests and through the examination of field running for one year, a new process of normal temperature aerobic hydrolytic acidification biological reaction was used to eliminate the residual sludge produced during treating organic wastewater and realized “zero discharge” of the sludge.The new process features convenient operation and management, which can also increase the qualified rate of COD Cr of the original system by 5%～15%.Therefore it can be applied especially to the system of treating organic wastewater containing nitrogen.
