Environmental Safety of Motor Transport Enterprises within Urban Areas

摘要

Water resources are the main component of technological processes occurring in industry, therefore the issue aimed at increasing the level of environmental safety, in particular, wastewater treatment without adverse impact to the environment and human health is relevant. The preliminary environmental analysis of the motor transport enterprise (MTE) activity has been carried out. It has been established that about twenty environmental aspects identified in the departments of technical inspection and repair and service have an adverse impact on the state of the environment. Substantial impact on the environment occurs when sewage containing petroleum products, washing liquids, waste lubricants and contaminated by products of tissue origin enters the soil and water objects and their resources. On the basis of the preliminary analysis, the authors have identified the environmental aspects of the company's activity and proposed an environmental policy as an essential element for the implementation of the environmental management system. Researchers conducted with the aim of determination of motor transport enterprise sewage composition have revealed excessive content of polluting chemical substances and namely: suspended substances, phosphates, iron, fats, oil products and synthetic detergents. The expediency of the use of carbonaceous sorbents of vegetable origin, which were obtained from the waste wood industry for wastewater treatment of the enterprise, was investigated. It was revealed that the process of sorption purification improved the quality of waste water of the motor transport enterprise to the standard values. The proposed recommendations for the implementation of the environmental management system will gradually reduce the impact of the company on the main components of the biosphere. Effective implementation of the environmental management system will help to increase the competitiveness of the enterprise and lead to an economic effect by saving raw materials, materials, energy resources, reducing environmental payments and penalties.
