Abstract

Disposal of poultry sludge is one of the great challenges facing cities because of very strict requirements for landfilling and the scarcity of space for landfills. The present study was therefore aimed at evaluating the physical and chemical properties of poultry sludge and its suitability for reuse in agricultural and non-agricultural applications. Three samples were collected from sludge at the wastewater treatment plant of Al-Thuraya slaughterhouse in Al-Mafraq District, Jordan. The physical and biochemical properties of these samples were analyzed. Also, elemental composition and heat value were determined. The results indicated that poultry sludge had a slightly alkaline pH and a total moisture content of 20%, as well as an average total solid of 80%. The dry solid sludge had a volatile solid content of 94.9% and 5.1% of ash. Also, dry sludge had a high protein content (62 %) followed by carbohydrate (20%) and fiber (17%), with fat being around 1%. The major elements in the sludge were carbon (65.5%) followed by nitrogen (16%), phosphorous (5 %) and sulfur (2%). Heavy metal concentrations in dry sludge ranged from 0.01 to 2 mg/kg. These heavy metal concentrations were well below the safe limits recommended by legislators for sludge used as a fertilizer. The findings from this study revealed that dry poultry sludge offers a wide range of potential uses as fertilizer, animal feed and a source of energy, and it should be considered as a potentially valuable and sustainable resource rather than a waste product.

家禽污泥理化性质评价及其在农业和非农业应用中的适用性

家禽污泥的处理是城市面临的巨大挑战之一，因为填埋要求非常严格，而填埋空间稀缺。因此，本研究旨在评估家禽污泥的物理和化学性质及其在农业和非农业应用中重复使用的适用性。从约旦Al-Mafraq地区Al-Thuraya屠宰场废水处理厂的污泥中收集了三个样本。分析了这些样品的物理生化特性。测定了样品的元素组成和热值。结果表明，家禽污泥pH值为微碱性，总含水率为20%，平均总固形物为80%。干燥固体污泥挥发性固体含量为94.9%，灰分含量为5.1%。此外，干污泥的蛋白质含量较高(62%)，其次是碳水化合物(20%)和纤维(17%)，脂肪含量约为1%。污泥中主要元素为碳(65.5%)，其次为氮(16%)、磷(5%)和硫(2%)。干污泥中重金属浓度为0.01 ~ 2 mg/kg。这些重金属浓度远远低于立法者建议的用作肥料的污泥的安全限值。这项研究的结果表明，干燥的家禽污泥具有广泛的潜在用途，可作为肥料、动物饲料和能源来源，应将其视为一种潜在的有价值和可持续的资源，而不是废物。
