Abstract
Przedmiotem wynalazku jest sposób utylizacji osadów pofermentacyjnych z procesu współfermentacji osadów z uzdatniania wody i z oczyszczania ścieków komunalnych. Przeznaczony do utylizacji osad pofermentacyjny jest odwadniany do wilgotności mniejszej niż 20%<sub>mas</sub>, rozdrabniany mechanicznie do wielkości ziaren <10 mm, wprowadzany do pieca fluidyzacyjnego nad rozpalone złoże fluidalne w sposób ciągły i spalany przy utrzymywaniu stałej temperatury złoża w granicach 650°C do 1000°C. Czynnikiem fluidyzującym materiał złoża jest powietrze, które wdmuchuje się, przeciwprądowo w stosunku do wprowadzanego materiału, w ilości zapewniającej wytworzenie strefy utleniającej w całej objętości złoża. W przypadku obniżenia temperatury złoża poniżej 850°C wprowadza się regulowany strumień dodatkowego paliwa gazowego. Po usunięciu części palnych substancja mineralna jest odbierana ze złoża fluidalnego. Głównymi składnikami uzyskanego materiału są kwarc, glinokrzemiany oraz tlenki żelaza. Proporcje składników są uzależnione od materiału wsadowego. Uzyskany tym sposobem inertny chemicznie materiał mineralny znajduje zastosowanie jako neutralny dla środowiska materiał podsypkowy lub też jako dodatek do zapraw i betonów oraz ceramiki budowlanej.The subject of the invention is a method of utilization of post-fermentation sludge from the process of co-fermentation of sludge from water treatment and municipal sewage treatment. The post-fermentation sludge intended for disposal is dehydrated to a moisture content of less than 20% <sub>mass</sub>, mechanically comminuted to a grain size of <10 mm, introduced into a fluidizing furnace over a heated fluidized bed in a continuous manner and incinerated while maintaining a constant bed temperature at between 650°C and 1000°C. The agent that fluidizes the bed material is air, which is blown in counter-current to the introduced material, in the amount ensuring the creation of an oxidizing zone in the entire volume of the bed. If the bed temperature drops below 850°C, a regulated stream of additional gaseous fuel is introduced. After the combustible parts are removed, the mineral substance is collected from the fluidized bed. The main components of the obtained material are quartz, aluminosilicates and iron oxides. The proportions of the ingredients depend on the input material. The chemically inert mineral material obtained in this way is used as an environmentally neutral ballast material or as an additive to mortars, concretes and building ceramics.
