Method for producing mineral-organic fertilizers based on sewage sludges, preferably with prolonged action

摘要

the object of the application is way to produce fertilizers based on bituminous - organic sludge, especially prolonged action.method of manufacturing organic fertilizer bituminous - based sewage sludge, especially prolonged action, is the processing of sewage sludge, after analysis of their chemical composition.the content of hazardous constituents and release, by conditioning phosphorus compounds, resins, preferably formaldehydowymi, mixture of minerals, wypełniającymi substances,advantageously the lime and dolomitów, ujednorodnianiu through mixing, higienizacji chemical and thermal, preferably with additions of active biologically.after granulowaniu otoczkuje, preferably polymer composition.sewage sludge having a water content of from 10% to 75% ujednorodnia ortho phosphoric acid, and then successively with urea formaldehyde resin.mixed with additional ingredients and substances wypełniającymi: an acrylic polymer is linear and / or supersorbentem in proportion by weight: sludges from 10% to 75%.phosphoric acid of 30% to 60%, urea - formaldehyde resin resin, from 10% to 60%, the mixture of minerals: nitrogen phosphorus potassium n, p, k, mg, ca, magnesium, calcium, iron, manganese mn, fezinc zn, copper cu, boron b and / or molybdenum mo, in quantities of from 5 to 50%, superabsorbent from 0,1 to 5%, the biologically active substances from 0,1 to 1%, filling materials and spajające from 1% to 10%.preferably in the form of nieusieciowanego polikwasu acrylic acid, after which higienizuje are thermally and granuluje.
