Abstract

Sposób charakteryzuje się tym, że częściowo odwodnione osady ściekowe zawierające od 15 do 30% wagowych suchej masy osadu miesza się z biomasą roślinną, a uzyskaną mieszaninę formuje się mechanicznie poprzez wyciskanie do postaci nitek lub granulatu. Jako biomas roślinną stosuje się odpady roślinne o wilgotności do 25%, zawierające rozdrobnione włókna celulozowe o długości do 1 cm i wymiarze poprzecznym od 0,1 do 1,0 mm, które dodaje się do osadu ściekowego w ilości od 10 do 35% wagowych do uzyskania mieszaniny o wilgotności od 45% do 65%, odczynie pH 5,5-6,5 i zawartości substancji organicznej od 40%-80% przy stosunku C:N około 25-35. Następnie mieszaninę poddaje się procesom autotermicznym z udziałem bakterii termofilnych w czasie od jednej do siedmiu dób, po czym do uzyskanej mieszaniny o zawartości wody od 40 do 50% wagowych dodaje się ponownie odpady roślinne o wilgotności do 25%, zawierające rozdrobnione włókna celulozowe o długości do 1 cm wymiarze poprzecznym od 0,1 do 1,0 mm, w ilość od 5% do 10% wagowych, a po wymieszaniu poddaje się formowaniu poprzez wyciskanie a następnie sezonowaniu.The method is characterized in that partially dehydrated sewage sludge containing from 15 to 30% by weight of dry matter of the sludge is mixed with plant biomass, and the obtained mixture is mechanically formed by pressing into threads or granules. Vegetable waste with a moisture content of up to 25%, containing ground cellulose fibers up to 1 cm in length and transverse dimension from 0.1 to 1.0 mm, which is added to the sludge in an amount of 10 to 35% by weight is used as plant biomass. obtaining a mixture with a humidity of 45% to 65%, a pH of 5.5-6.5 and an organic content of 40% -80% at a C: N ratio of about 25-35. Then the mixture is subjected to autothermal processes with the participation of thermophilic bacteria for one to seven days, after which the resulting mixture with a water content of 40 to 50% by weight is again added vegetable waste with a moisture content of up to 25%, containing ground cellulose fibers up to 1 cm in transverse dimension from 0.1 to 1.0 mm, in an amount from 5% to 10% by weight, and after mixing is formed by extrusion and then seasoning.
