The subject of the paper is eco-technological procedure of the treatment of the sludge generated during conventional purification (Cn(-) oxidation, Cr(6+) reduction, chemical precipitation of the other metals) of the wastewater from galvanic process. The detailed analysis of the waste sludge with the determination of high flow (the water eluate) and low flow (HNO3-eluate) fraction as Cu(2+), Cr(3+), Cd(2+), Ni(2+), Pb(2+), Zn(2+). The point of the paper is the treatment of the sludge as the dangerous waste into useful product glass-ceramics, with eliminating of the generation of the dangerous and harmful materials in environment. Experimental investigation has achieved the point and approved that with this procedure it is possible to transform chemical active matters (Cu(2+), Cr(3+), Cd(2+), Ni(2+), Pb(2+), Zn(2+)) using the phase and chemical transformation into very stable structure where the pollutants can not be activated even under critical conditions as high temperature, influence of acids and alkalines, etc.

This paper deals with microbiological and chemical analysis of waste mud, produced in wastewater purification plants of the oil refinery. After digest, mud is removed to the filter press. Compressed mud is placed and stored on the storage yard. Content of organic, anorganic and oil matters and also heavy metals contents were determined. Microbiological analysis comprised determination of total count of aerobic organotrophic organisms and many physiological groups of bacteria. As the indicator of the general biochemical activity, enzymatic (dehydrogenase and phosphatase) activities were determined. Waste mud was mixed with soil (chernozem) in 20%, 40% and 60% amount relations. Changes of activities and quantitative fluctuations of the present microflora were observed after 15 and 30 days. Gained results should enable assessing of using-ability of waste mud in soil-quality improvement, in the sense of its utilization as the fertilizer.

Reduction of odours by spraying deodorisation products | Reduction des nuisances olfactives par pulverisation de produits de desodorisation

Face au developpement de l'utilisation de produits de desodorisation dits "neutralisants" ou "destructeurs" des odeurs, en pulverisation dans l'atmosphere, a l'emission ou a proximite immediate d'ouvrages responsables d'odeurs, l'INERIS (Institut national de l'environnement industriel et des risques) a procede, pour le compte du ministere de l'Amenagement du Territoire et de l'Environnement et de l'ADEME (Agence de l'environnement et de la maitrise de l'energie), a une etude visant une meilleure connaissance des performances de ces produits. Deux types de produits ont ete testes, en pulverisation ou en lavage sommaire des gaz, dans des conditions reelles d'effluents industriels, et dans des conditions de laboratoire, en determinant les efficacites de traitement olfactometriques (reduction de l'odeur) et physico-chimiques (abattement des composes responsables des odeurs) au moyen d'analyses simultanees. A l'issue de ces essais, on peut conclure que les produits de traitement des odeurs, proposes actuellement sur le marche pour desodoriser l'air vicie dans l'industrie, doivent etre utilises avec une grande prudence. En effet, la plupart des produits de pulverisation peuvent apporter un reel confort olfactif par effet de masquage (remplacement d'une mauvaise odeur par une odeur "agreable"), mais il ne faut pas en attendre, a priori, un abattement significatif des polluants presents dans l'air malodorant
