摘要
在全区范围随机抽查部分湿垃圾就地处置设施,进行废水、环境空气和噪声监测,发现:35.1%的废水点位超标,铁、粪大肠菌群、化学需氧量等12项指标超标;臭气浓度超标点位约占52.6%,且上风向与下风向均存在不同程度超标情况;声环境基本满足二类昼间环境标准限值要求。研究结果可了解湿垃圾就地就近处理设施环保达标情况,及时规避相关环境风险。
A random check was carried out for part of wet waste in-place disposal facilities within the whole district to monitor the effl uent,ambient air and noise.It has been found that at 35.1%of the effluent releasing spots,twelve variables including iron,fecal coliform,COD and etc.were incompliant with the standard,and odour content was out of standard limit with varying degree at 52.6%spots even in the both upwind and downwind directions,whilst the acoustic environment basically fulfil the Class 2 diurnal standard limit requirements.Those fi ndings could reveal the compliance situation of in-place or nearby facilities for wet waste disposal so as to timely avoid related environmental risks.
