Skład, charakterystyka oraz właściwości krwi pozwalają przypuszczać, że ścieki zawierające wysokie stężenia tego płynu ustrojowego będą wydajnie degradowane techniką pogłębionego utleniania z zastosowaniem odczynnika Fentona.

The paper presents possibility of Fenton reaction application in degradation processes of wastewater with large concentration of blood. Composition and character-istic make it possible to think that wastewater with large concentration of blood may be effectively treated by advance oxidation process with Fenton reagent. Iron included in blood can be potential source of Fe2+ or Fe3+ ions, catalysts of Fenton reaction. Proposed solution of blood coming from the meat industry neutralization is perspective, genuine and not described yet method based on advanced oxidation technique. Preliminary examinations and literature data let suppose it becomes the alternative, economically justified and effective technology of blood and wastewater with addition of body fluids neutralization. Effects of pollutants degradation with application of Fenton reaction assure: oxidation and coagulation of organic pollutants in wastewater with high concentration of blood, including removal putrescible substances; removal of odors; removal of biogenic compounds, mainly phosphorus; elimination of the red color. Other potential effects of advanced oxidation technique may concern: improvement in the sanitary properties of wastewater from the meat industry, through removal of pathogenic organisms and parasites; elimination or limiting the toxicity. Research in laboratory and technical scale showed that Fenton reaction is a effective method of wastewater with blood treatment. Decrease of organic compounds (COD) was about 70% in technical scale installation. There was used only 0.4 g Fe2+/dm3; 1.2 g H2O2/dm3 doses. Further research will confirm and substantiate the direct influence of blood composition and properties on the efficient course of Fenton reaction. It will be possible on its base to work out new pioneer technologies of utilization recycling of this fluid waste, but will also contribute to explaining chemical processes occurring in biological systems. It is very essential when taking into consideration, that many cellular mechanisms connected with free radicals and with their destructive influence on organelles remains solved insufficiently.
