沈阳市污泥堆放场恶臭监测与评估技术

为治理祝家污泥堆放场恶臭污染问题,对污泥堆放场实施综合治理工程,同时针对污泥自身及环境影响特征,采用臭气浓度和臭气强度指标的监测,并扩展性应用快速判定和检测技术,对工程进度不同阶段的治理进行即时监测。结果表明:工程实施前后期上下风向厂界指标分别为:臭气强度4⁵级、25级、2².5级;臭气浓度602.5级;臭气浓度60⁸0、1080、10²0;50020;500¹500、401500、40⁵5;硫化氢0.08 mg/m3、0.002mg/m 3、0.003mg/m3、0.001 mg/m3。工程实践证明,此类堆放场处理前厂界相关指标严重超标,处理后厂界达标率100%。

Monitoring and Evaluation Technologies of Sludge Yard Odour in Shenyang

Comprehensive treatment project was implemented to solve the odour pollution of Zhujia sludge yard. According to the characteristics of sludge and its environmental impacts, the odour concentration and density were monitored in different periods of treatment, also the snap judgement and determination technologies were used.The results showed the upwind and downwind boundary indexes before and after the treatment as follows： odour densities of 2-3 degree, 0-1 degree,and 4-5 degree, 2-2.5 degree, odour concentrations of 60-80, 10-20, and 500-1500, 40-55, H2S of 0.08 mg/m^3, 0.002mg/m^3, and 0.003mg/m^3, 0.001mg/m^3. It indicated that the treatment efficiency was significant,the compliance rate of boundary indexes was 100% after treatment, while the indexes were seriously exceed the standard before.
