The use of sewage sludge in agriculture decreases the pressure on landfills. In Romania, massive investments have been made in wastewater treatment stations, which have resulted in the accumulation of important quantities of sewage sludge. The presence of these sewage sludges coincides with large areas of degraded agricultural land. The aim of the present article is to identify the best technological combinations meant to solve these problems simultaneously. Adapting the quality and parameters of the sludge to the specificity of the land solves the possible compatibility problems, thus reducing the impact on the environment. The physico-chemical characteristics of the fermented sludge were monitored and optimal solutions for their treatment were suggested so as to allow that the sludge could be used in agriculture according to the characteristics of the soils. The content of heavy metals in the sewage sludge was closely monitored because the use of sewage sludge as a fertilizer does not allow for any increases in the concentrations of these in soils. The article identifies those agricultural areas which are suitable for the use of sludge, as well as ways of correcting some parameters (e.g., pH), which allow the improvement of soil quality and obtained higher agricultural production.

在农业土地上使用污泥的最佳解决方案

农业中使用污水污泥可减轻垃圾填埋场的压力。在罗马尼亚，对废水处理站进行了大量投资，导致大量污泥的积累。这些污泥的存在与大面积的退化农业土地相吻合。本文的目的是确定旨在同时解决这些问题的最佳技术组合。使污泥的质量和参数适应土地的特殊性可以解决可能的兼容性问题，从而减少对环境的影响。监测了发酵污泥的理化特性，并提出了最佳的处理方案，以便根据土壤的特性将污泥用于农业。污水污泥中的重金属含量受到密切监测，因为使用污水污泥作为肥料不会增加土壤中这些重金属的浓度。该文章指出了那些适合使用污泥的农业地区，以及一些校正参数（例如pH值）的方法，这些方法可以改善土壤质量并获得更高的农业产量。污水污泥中的重金属含量受到密切监测，因为使用污水污泥作为肥料不会增加土壤中这些重金属的浓度。该文章指出了那些适合使用污泥的农业地区，以及一些校正参数（例如pH值）的方法，这些方法可以改善土壤质量并获得更高的农业产量。污水污泥中的重金属含量受到严密监控，因为使用污水污泥作为肥料不会增加土壤中这些重金属的浓度。该文章指出了那些适合使用污泥的农业地区，以及一些校正参数（例如pH值）的方法，这些方法可以改善土壤质量并获得更高的农业产量。
