鼓风曝气系统管道噪声控制研究

Study on Noise Control of Aeration Pipeline

利用声压测量技术判知某城市污水处理厂鼓风曝气系统以管道再生噪声为主要噪声源,采取加大管道直径、减少管道截面变化、加接消声器等措施后,噪声污染已控制到国家允许标准以下。

It was found that regenerative noise of pipeline is the main noise source of aeration system in sewage treatment plant with sound pressure measurement. Increasing diameter of pipeline, decreasing variation of pipe cross section and insetting silencers could reduce noise to meet the National Standard.
