    The issues of rational use of natural resources, ecological safety and environmental protection are extremely urgent and require immediate human influence on the optimization of technological processes, reducing the impact on the ecosystem. The implementation of food industry technology is accompanied by the formation of a significant amount of wastewater, into which about a third of processed raw materials go, and the concentration of polluting components in them is 10...100 times higher than in household water. The choice of wastewater treatment methods depends on their composition, prospects for further use, the economic feasibility of applying the methods, and the payback rate of the equipment. Therefore, the modern direction of the development of scientific research and wastewater treatment technology consists in the development of fundamentally new methods of deep wastewater treatment and the study of the possibility of using sorbents of natural and artificial origin.

    Ecological problems of enterprises of alcohol industry
    (Видавництво Львівської політехніки, 2020-02-10) Havryshko, Marianna; Popovych, Olena; Yaremko, Halyna; Lviv Polytechnic National University
    The issue of industrial water treatment and food waste disposal is particularly relevant, especially for the alcohol industry. The problem of wastewater treatment and waste accumulation in the process of alcohol production is due to high chemical and biological oxygen demand, specific colour and odour, a large number of suspended substances, low pH. Therefore, the choice of promising wastewater treatment technologies is of paramount importance to ensure the ecological safety of the environment. The purpose of the paper is 1) to analyze the state of the alcohol industry in Ukraine in recent years, and methods of its waste disposal; 2) to investigate and determine effective methods of waste disposal in the alcohol industry.
