Abstract
Przedmiotem zgłoszenia jest sposób wytwarzania nawozów mineralno-organicznych na bazie osadów ściekowych, zwłaszcza o przedłużonym działaniu. Sposób wytwarzania nawozów mineralno-organicznych na bazie osadów ściekowych, zwłaszcza o przedłużonym działaniu, polega na przetwarzaniu osadów ściekowych, po analizie ich składu chemicznego, zawartości składników niebezpiecznych i dopuszczeniu, poprzez kondycjonowanie związkami fosforu, żywicami, korzystnie formaldehydowymi, mieszaniną składników mineralnych, substancjami wypełniającymi, korzystnie związkami wapna i dolomitów, ujednorodnianiu poprzez mieszanie, higienizacji chemicznej i termicznej, korzystnie z dodawaniem substancji aktywnych biologicznie, po granulowaniu otoczkuje się, korzystnie kompozycją polimerową. Osady ściekowe o zawartości wody od 10% do 75% ujednorodnia się kwasem ortofosforowym, a następnie kolejno z żywicą mocznikowo-formaldehydową, miesza się z dodatkowymi składnikami i substancjami wypełniającymi: akrylowym polimerem liniowym i/lub supersorbentem, w proporcji wagowej: osady ściekowe od 10% do 75%, kwas ortofosforowy w ilości 30% do 60%, żywica mocznikowo-formaldehydowa od 10% do 60%, mieszanina składników mineralnych: azotu N, fosforu P, potasu K, magnezu Mg, Wapnia Ca, żelaza Fe, manganu Mn, cynku Zn, miedzi Cu, boru B i/lub molibdenu Mo, w ilości od 5 do 50%, superabsorbent od 0,1 do 5%, substancje biologicznie aktywne od 0,1 do 1%, substancje wypełniające i spajające od 1% do 10%, korzystnie w postaci nieusieciowanego polikwasu akrylowego, po czym higienizuje się termicznie i granuluje.The subject of the notification is a method for producing mineral-organic fertilizers based on sewage sludge, especially with prolonged action. The method of producing mineral-organic fertilizers based on sewage sludge, especially with prolonged action, consists of processing sewage sludge, after analyzing their chemical composition, content of hazardous components and admission, by conditioning with phosphorus compounds, resins, preferably formaldehyde, a mixture of mineral components, fillers , preferably with compounds of lime and dolomites, homogenisation by mixing, chemical and thermal hygienization, preferably with the addition of biologically active substances, after pelleting, it is enveloped, preferably with a polymer composition. Sewage sludge with a water content from 10% to 75% is homogenised with orthophosphoric acid, and then successively with urea-formaldehyde resin, mixed with additional components and fillers: acrylic linear polymer and / or supersorbent, in weight proportion: sewage sludge from 10 % to 75%, orthophosphoric acid in the amount of 30% to 60%, urea-formaldehyde resin from 10% to 60%, a mixture of mineral components: nitrogen N, phosphorus P, potassium K, magnesium Mg, calcium Ca, iron Fe, manganese Mn , zinc Zn, copper Cu, boron B and / or molybdenum Mo, in an amount of 5 to 50%, superabsorbent from 0.1 to 5%, biologically active substances from 0.1 to 1%, fillers and binders from 1% up to 10%, preferably in the form of uncrosslinked polyacrylic acid, after which it is thermally hygienized and granulated.
