Abstract

Przedmiotem wynalazku jest sposób wytwarzania nawozu wieloskładnikowego, zawierającego aminokwasy oraz mikro i makroskładniki nawozowe ze strużyn skór, pochodzących z przemysłu garbarskiego. Sposób polega na tym, że rozdrobnione chromowane lub niechromowane strużyny poddaje się procesowi hydrolizy kwasowej i ewentualnie zasadowej, w temperaturze od 20 do 150 C, w obecności jonów mikroelementów z grupy Cu, Mn Zn, pochodzących z soli siarczanowych, w stężeniu od 0,01 do 5% każdy, w proporcji strużyn garbarskich do czynnika hydrolizującego od 0,5 : 1 do 100 : 1. Hydrolizat neutralizuje się do uzyskania pH od 2,0 do 6,0. Przy czym strużyny poddaje się hydrolizie w mieszaninie kwasów: fosforowego (V) w stężeniu od 10 do 40%, fumarowego w stężeniu od 0,5 do 10%, szczawiowego w stężeniu od 0,5 do 10% oraz cytrynowego od 0,5 do 10%. Alternatywnie strużyny poddaje się hydrolizie w mieszaninie kwasów: siarkowego (VI) w stężeniu od 10 do 40% i fosforowego (V) w stężeniu od 10 do 40%, w temperaturze od 20 do 150°C. Zneutralizowany materiał pochodzący z hydrolizy kwaśnej filtruje się w nuczy filtracyjnej, uzyskując nawóz płynny oraz nawóz stały. Korzystnie oddzielony osad granuluje się z popiołem pochodzącym ze spalania biomasy w proporcji osadu do popiołu od 0,2 : 1 do 1 : 1. W odmianie sposobu, równolegle z hydrolizą kwasową strużyn skór garbarskich, część materiału poddaje się hydrolizie alkalicznej, przy użyciu wodorotlenku potasu, o stężeniu od 5 do 80% m/m, w temperaturze od 20 do 100°C, zachowując stosunek strużyn do zasady w zakresie od 0,5 : 1 do 100 : 1. Wytworzone hydrolizaty kwaśny i alkaliczny miesza się ze sobą do uzyskania pH od 5,0 do 6,0 w proporcji od 0,5 : 1,5 do 2 : 0,5 odpowiednio hydrolizatu kwaśnego i alkalicznego.The subject of the invention is a method of producing a multi-ingredient fertilizer containing amino acids as well as micro- and macro-nutrients from leather shavings from the tanning industry. The method is based on the fact that shredded chromium-plated or non-chromium-plated shavings are subjected to the process of acidic and possibly alkaline hydrolysis, at a temperature of 20 to 150 C, in the presence of ions of microelements from the group Cu, Mn Zn, derived from sulphate salts, in a concentration of 0.01 up to 5% each, in the ratio of tanning shavings to hydrolyzing agent from 0.5:1 to 100:1. The hydrolyzate is neutralized to a pH of 2.0 to 6.0. The shavings are hydrolyzed in a mixture of acids: phosphoric (V) at a concentration of 10 to 40%, fumaric at a concentration of 0.5 to 10%, oxalic at a concentration of 0.5 to 10% and citric acid from 0.5 to 10% 10%. Alternatively, the shavings are hydrolyzed in a mixture of acids: sulfuric (VI) at a concentration of 10 to 40% and phosphoric (V) at a concentration of 10 to 40%, at a temperature of 20 to 150°C. The neutralized material from the acid hydrolysis is filtered in a slurry filter to obtain a liquid fertilizer and a solid fertilizer. Preferably, the separated sludge is granulated with ash from biomass combustion in a sludge to ash ratio of 0.2:1 to 1:1. , with a concentration of 5 to 80% m/m, at a temperature of 20 to 100°C, maintaining the ratio of shavings to alkali in the range of 0.5: 1 to 100: 1. The acidic and alkaline hydrolysates produced are mixed together until obtaining pH from 5.0 to 6.0 in the proportion of 0.5 : 1.5 to 2 : 0.5 of acidic and alkaline hydrolyzate, respectively.
