- 摘要:
- 城镇污水污泥中聚集了很多污染物，是以污泥在燃煤电厂协同燃烧时，排放值中会较着增添额外的重金属输入（特别是诸如汞等高挥发性物资），这是应将污水污泥燃煤电厂协同燃烧量限制在很小比例的缘由之一；限制污水污泥协同燃烧量的另外一缘由是凡是用作建筑材料的粉煤灰的质量必需合适相干建筑材料尺度。污泥燃煤电厂协同燃烧如简单沿用《火电厂年夜气污染物排放尺度》(GB 13223—2011),而不连系污泥的污染物特征（特别在污泥中的重金属浓度遍及高在燃煤的重金属浓度的环境下），则具有电厂“稀释排放”或二口恶英类等其他未检测污染物的浓度超标的嫌疑。污泥电厂协同燃烧须留意污泥的“污染物”特征，而不成简单将污泥视作“生物资”，污泥的协同处置并不是简单无前提的协同，而须周全遵守HSE准绳。
- Abstract:
- Urban sewage sludge is a sink for a number of pollutants，and when the sewage sludge is co-incinerated in coal-fired power plants, the additional input of heavy metals (particularly highly volatile substances such as mercury) becomes a remarkable emission issue. This is one of the reasons that the sewage sludge co-incineration in coal-fired power plants should be limited to a very small amount. Another reason for limiting the co-incinerated sewage sludge quantity is the quality of the fly ash which is usually used as a building material, which must be evaluated by the relevant building material standards. Since the concentration of heavy metals in the sludge is generally higher than that in coal, the sludge co-incineration in coal-fired power plants may be suspected of excessive concentrations of power plants such as “dilution emissions” or other undetected pollutants such as dioxins when the Emission Standard of Air Pollutants for Thermal Power Plants (GB 13223-2011)is simply used without considering the pollutant characteristics of the sludge. The co-incineration of sludge in power plants must pay attention to the “contaminant” characteristics of the sewage sludge, rather than simply treating the sludge as a kind of “biomass”. The synergistic treatment of sludge is not a simple and unconditional synergy, and the HSE principle must be fully applied.
