Purification process of contaminated soils, water and deposits

Rešení se týká zpusobu cištení kontaminovaných zemin, vod a usazenin, které je charakterizováno tím, že se biotický a abiotický rozklad halogenovaných látek podporí prídavkem syrovátky a železné drte za soucasného strídání anaerobních a aerobních podmínek, pricemž se syrovátka pridává v dávce od 0,5 do 50 % hmotn., vztaženo na hmotnost zeminy, vody nebo usazeniny a železná drt v dávce od 0,005 do 10 % hmotn. vztaženo na hmotnost zeminy, vody nebo usazeniny, pri hodnote pH v rozmezí 5 až 10, teplote inkubace od 0 .degree.C do 60 .degree.C a obsahu sušiny zeminy, vody nebo usazeniny 1 až 90 % hmot. a pricemž se strídání anaerobních/aerobních podmínek provádí v intervalu 1 až 15 dní. The present invention relates to a purification process of contaminated soils, water and deposits, which purification process is characterized in that both biotic and abiotic degradation of halogenated substances are supported by the addition of whey and iron crushed material under simultaneous alternation of anaerobic and aerobic conditions, whereby whey is added in an amount of from about 0.5 to about 50 percent by weight, based on the soil, water or deposit total weight and the iron crushed material is added in an amount from about 0.005 to about 10 percent by weight, based also on the soil, water or deposit total weight, at a pH value within the range of 5 to 10, incubation temoperature in the range of 0 to 60 degC and dry matter content of soil, water or deposit in the range of 1 to 90 percent by weight and wherein the alternation of the anaerobic and aerobic conditions is carried out in the interval of 1 to 15 days.
