Reed Bed

Macrophyte plants e.g. reed, cattails, bulrush, can be applied to sewage sludge utilisation. One of the first facilities of this type in the Gdansk region (Northern Poland) was established in Darzlubie in 1995 and primary sludge has been utilised in reed beds there. The objective of the undertaken research was evaluating the influence of sewage sludge storage on its chemical and biological properties. A total of 5.5 m thick layer of primary, anaerobically stabilised sludge (moisture 90-96%) was loaded to the reed bed during 6 years of operation. As a consequence of dewatering and biochemical transformation, the sludge layer decreased to 30 cm. Moisture, organic matter, total nitrogen and total phosphorus contents, as well as coli index, Clostridium perfringens index and the number of Ascaris lumbricoides ova were measured. Also the contents of heavy metals (Cu, Pb, Zn, Ni, Cr and Cd) were determined in sludge samples. The study showed that sludge storage in reed beds results in dewatering and partial stabilisation. In the reed lagoons in Swarzewo and Zambrow, dewatering of secondary sludges was investigated. The results of measurements of the quality of sludge and effluent from the reed lagoon in Zambrow are also presented.

Reed Bed

The problem of utilization and management of sewage sludge originating from small wastewater treatment plants is still unsolved in Poland. One of the waste-free technologies of sludge utilization is the reed bed method. Two experimental facilities of this type have been operating for four years in the Gdansk Region: a reed bed in Darżlubie and a reed lagoon in Swarzewo. The investigation was aimed at evaluating the influence of the storage on chemical and biological properties of sewage sludge deposited in beds. Tests were carried out in the period of two years. Moisture, organic matter, total nitrogen and total phosphorus contents as well as coli index, Clostridium perfringens index and number of Ascaris lumbricoides eggs analyzes were measured. Analyses of contents of heavy metals Cu, Pb, Ni, Zn, Cr and Cd for sludge samples from Darżlubie were additionally carried out. Tests proved that the utilization of sludge in reed beds allows using the end product as a fertilizer in agriculture. The most important problem is increasing of heavy metals content and number of Ascaris lumbricoides per mass of sludge during long time storage.

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.
