竹园第一污水处理厂除臭工程设计

分析了竹园第一污水处理厂的臭气污染源，确定了该污水厂除臭工程的范围（生物絮凝反应沉淀池的进水端和出水槽、污泥浓缩池、污泥脱水机房）及内容（降低H2S、NH3和臭气浓度）。针对主要污染源，经方案比选确定了采用天然植物提取液除臭方法，介绍了该除臭工程的设计及运行效果。结果表明，采用天然植物提取液除臭方法可使该污水厂的H2S和NH3指标达到厂界排放要求，但对臭气浓度的去除效果尚待提高。

Design of Odor Removal Project for Zhuyuan First WWTP

The odor pollution source of the Zhuyuan first WWTP was analyzed. The paper determined the scope of the odor removal project including the inlet end and the outlet duct of the bioflocculation reaction and settling tank, sludge thickener, sludge dewatering house, and its object of reducing the H2S, NH3 and odor concentrations. Aimed at the main odor pollution source, the odor removal method using natural plant extraction solution was determined after the proposal comparison, and the design and application results of the odor removal project were introduced. The result shows that this method allows the index of H2 S and NH3 to achieve the discharge requirement at the plant boundary, but the odor removal efficiency is not good enough.
