摘    要:造纸污泥经过交替好氧厌氧堆肥处理后施加到菜园土中,进行了盆栽实验.实验结果表明,造纸污泥堆肥作为农业肥料,可以增加作物的生物量,提高土壤的养分含量,有效改良土壤的物理性状:土壤中的重金属在作物中的累积行为呈现不同的规律,但最后均趋于一个极值;重金属生物累积的峰值均低于国家蔬菜重金属含量标准.

关 键 词:造纸污泥  堆肥  农业利用  重金属

Abstract:Agriculture test of kailyard soil mixed with paper mill sludge, which had been alternatively treated with aerobic and anaerobic composting for 40 days, was carried out in a basin scale. The results showed that this soil amendment could promote the biomass amount of the crop, increase the nutrients of the soil and improve the physical characteristics of the soil. The accumulation amount of heavy metals in the plant finally reached the maximum value although the accumulation behavior of the heavy metals was various. The measurement results demonstrated that the total amount of heavy metal in the crop was lower than the allowance of the national standard of foods. So the pulp and paper mill sludge compost was safe manure for the agriculture.
Keywords:paper mill sludge  compost  agriculture  heavy metals
