Abstract

The article considers the urgent problem of formation, storage and recycling of sludge materials of various compositions, generated as a result of industrial enterprises wastewater treatment and sanitation. It is pointed out that in spite of a lot of designs concerning the wastewater neutralization sludges recycling, the share of their efficient usage is still negligible. So, one of the most relevant trends of nature protection activity and the rational use of natural resources is developing a technology of these wastes reclamation and applying them for useful products manufacturing. The research of chemical, mineral and grain composition of ferrovanadium production sludge wastes, generated at waste waters neutralization at the «EVRAZ Vanadii Tula», Tula, Russia, has been carried out. A method of obtaining pigments for silicate paints on the basis of these sludges has been considered. The influence of the sludges' thermal treatment conditions on their mineral composition and the properties of paints based on them has been evaluated. The pigments content varies from 1 to 3 %. It has been demonstrated that the most promising is the usage of initial sludges and heat-treated at temperature 1000°С sludges as pigments for high-performance silicate paints.

Abstract

1. A study was made of the electrophysical properties of a number of aromatic betaines which did not have bonding between charged atoms. 2. The dielectric permeability of the substances studies proved to be somewhat higher in comparison with the majority of organic compounds and lay within the limits 2.9 - 3.9. 3. The temperature dependence of the betaines taken is described by the usual exponential law for organic substances. 4. Internal molecular variations which result in easier excitation of the electron system lead as a rule to a lowering of the 'activation energy' of conductivity.
