Opis:
The article deals with the problems of handling used motor oils on the railways of Ukraine. At the moment, this waste is transferred to other enterprises for disposal. But, based on international experience, it is advisable to be regenerated directly at the enterprise where it is formed. The purpose of this work is to develop a modern scheme for oil waste disposal. In this regard, various indicators were investigated, reflecting both the operational suitability of oils and their toxicological parameters. As a result, we proposed a scheme and selected special equipment for handling the used engine oils, which allows to reduce the technogenic load associated with their accumulation, handling and minimization, contributes to the return of oil to the technological process. The calculated value of the conditional environmental effect and the approximate payback period allowed us to draw conclusions about the undoubted environmental and economic effect of implementing the proposed scheme.

Opis:
Processing of metals by cutting under modern conditions becomes impossible without the use of effective cutting fluids. The main purpose of cutting fluids is cooling, lubrication of the workpiece processing area. Spent emulsion is a special type of wastewater, very dangerous to the environment, as it contains a large number of persistently emulsified petroleum products. The methods using various surfactants were tested for the cutting fluid disposal. The obtained results allowed proposing a general flow diagram of treatment of spent cutting fluids, as well as a block diagram of their purification. After processing the spent cutting fluids according to the proposed diagram, two products were obtained, namely water and sludge. This technology can be used in metalworking shops of railway enterprises, as well as the enterprises of machine-building, metallurgical and other industries where CF-effluents are formed within the wastewater complex. It will provide both an economic result through the reuse of water and will give a significant environmental effect by minimizing the amount of hazardous waste.
