Definitions

  • the invention relates to sludge from sewage treatment plants.
  • Sludge from sewage treatment plants is often treated with the purpose of obtaining material for soil recultivation and for use in agriculture and forestry. It is for this purpose that the sludge is being enriched, depending on its determined usage, for example by ash from heating power plants, products accrued from desulphurization of heating power plants, and organic material of animal or plant origin.
  • the resulted material is then used for filling an area that has been depreciated by previous usage.
  • a disadvantage of using such materials is the release of various forms of nitrogen, nutrients, heavy metals and their chemical forms, which cause unwanted contamination of soil and consequently also water.
  • Another disadvantage of stowing such a material is also a possible occurrence of gas production causing a green house effect, which is caused by the imperfect degradation of organic mass, for example of methane and carbon dioxide.
  • the objective of this invention is therefore to create such a substance for recultivation that is physically as well as biologically stable and significantly decreases the production of environment contaminants, while it is also suitable for usage in the areas of agriculture and forestry.
  • the essence of the sludge from sewage treatment plants according to this invention lies in the fact that it contains an addition of a biologically enzymatic compound with bound microorganisms.
  • the basic material can possibly contain an addition of mineral or nutritive material on a base of crushed mineral or organic mass.
  • the weight concentration of the biologically enzymatic compound with bound microorganisms is in the range of 0.02 through 5 percent when measured as of the laboratory sludge dry residue of the basic material.
  • the material advantageously contains ash from burning coal and solid reaction products on a calcium base from flue gas desulphurization.
  • the material When used in the areas of agriculture, forestry, and horticulture, the material contains waste of plant tissues, animal excrement, and manure including polluted straw and farm organic products, possibly also forestry waste.
  • a biologically enzymatic compound with bound microorganisms is added to the sludge from sewage treatment plants.
  • the weight concentration of the biologically enzymatic compound with bound microorganisms in the sludge is in the range of 0.1 through 1 percent.
  • the biologically enzymatic compound is represented especially by saprophyte microbiological strains that decompose organic mass under aerobic or anaerobic conditions; these strains can be possibly bound to a suitable mineral protective medium.
  • the biologically enzymatic compound with bound microorganisms is, before added to the sludge, mixed with yet another addition, for example with mineral or nutritive material on a base of crushed mineral or organic mass
  • the final content of the biologically enzymatic compound with bound microorganisms in the sludge is proportionately higher by the added addition.
  • the content of this bio compound in the sludge moves within the optimal effective range of 0.1 through 5 percent.
  • Sludge modified in this way is advantageously used not only for soil recultivation, but also as a fertilizer especially in agriculture, forestry, and horticulture.
  • the sludge When using the sludge for soil recultivation, it contains, as yet another addition, ash from burning coal and solid reaction products on a calcium base from flue gas desulphurization.
  • another addition of the sludge is the waste of plant tissues, animal excrement, and manure including polluted straw and farm organic products, possibly also forestry waste.
