POSSIBILITY OF USING EXCESSIVE ACTIVE SLUDGE AS ORGANOMINERALFERTILIZER
The article discusses the existing approaches to the separation of heavy metal ions from excess activated sludge for its further use as an organic fertilizer. Research has been carried out to determine the content of heavy metal ions in the formed excess activated sludge from the Makeevka treatment facilities. There is no data on the migration of metal ions from precipitates treated with calcium oxide under the influence of rain and melt waters. Therefore, studies of the migration of ions of heavy metals, were carried out using the example of zinc, cuprum and iron, from untreated activated sludge, and treated with quicklime.
