城镇污水处理厂噪声污染防治案例分析
- Title:
- Case Analysis of Noise Pollution Prevention in Urban Sewage Treatment Plant
- Keywords:
- sewage treatment plant; NIMBY effect; noise pollution
- 摘要:
- 随着城市发展，部分城镇污水处理厂厂界距离居民区越来越近，导致环境敏感度提升并极易引发“邻避效应”。污水处理厂应积极实施环境整治，提高环境管控标准和能力。某污水厂通过梳理分析找出厂内噪声污染关键点源和厂外周边环境关键敏感点，通过点源和面源治理，采用防止或减轻噪声的产生、阻断噪声传播、受众隔音等方法，实施一点一策的治理方案。厂内点源噪声平均下降8 dB（A），厂外居民楼噪声平均下降5~6 dB（A），取得良好降噪效果，多年来未发生居民投诉事件，达到“与邻为善，长期共存”的目标。
- Abstract:
- With the development of cities, the boundary between some sewage treatment plants is getting closer to residential areas, leading to increased environmental sensitivity and NIMBY effects. Sewage treatment plants should actively implement environmental remediation to improve environmental control standards and capabilities. By sorting and analyzing the key point sources of noise pollution in the plant and the key sensitive points of the surrounding environment outside the plant, a sewage treatment plant adopts the methods of preventing or reducing noise generation, blocking noise transmission and sound insulation of the audience to implement the one-by-one treatment scheme. The noise of point source in the plant is reduced by 8 dB (A) on average, and the noise of residential buildings outside the plant is reduced by 5-6 dB (A) on average, achieving a good noise reduction effect. There has been no complaint events from residents for many years, achieving the goal of “being friendly to neighbors and coexisting for a long time”.
