A new practical application of waste biological treatment of municipal wastewater activated sludge as a raw material for the composite-selective adsorbent is presented for the first time. Composite-sorbent contains up to 85% of the surplus activated sludge, and the rest-diatomit partlandtsement. It is shown that the adsorption capacity and selectivity of the resulting composite material is stabilized after electrochemical activation. The implementation preliminary purification step of waste water from ions of heavy metals allows to clean water to the regulatory requirements at minimum cost.

The method of liquidation of the map of viscous production wastes of additives is developed. The special collector of waste is developed for selection of waste from the card. Complex influence of the ground of waste of the oil refinery including three sections, a pond evaporator, a pond store of synthetic fatty acids, a dump of solid industrial wastes, the map of viscous production wastes of additives on the environment is investigated. It is revealed that the main pollutant are oil products (oil hydrocarbons), a steady trend of their accumulation in the environment is noted. The main fields of purpose of production wastes of additives are defined. They are applied as special additives at production of concrete and concrete goods and designs with increased requirements on water permeability, frost resistance, in quality of the plasticizing additives in concrete mixes, as the additive increasing elasticity and extensibility of bituminous coverings. Production wastes of additives in production of paints water and composite the general and special purpose are introduced. Production wastes of additives are used for recultivation of the lands polluted by oil and also purification of oil-containing sewage.

Drainage systems are one of the most important types of engineering equipment providing the necessary sanitary and hygienic conditions for the population life and the safe operation of industrial enterprises. A necessary condition for the long-term and reliable operation of water intake facilities (hereinafter WIF) is their effective protection against corrosion caused by various factors. Search for new engineering solutions to solve the problem of corrosion and biofouling on WIF is relevant at the moment, as it gives an opportunity to provide effective protection of WIF metal surfaces, which is directly related to the increase in the environmental performance of water enterprises.

В статье рассматривается подход к анализу вариантов реализации проекта развития сложной системы (объектов) в условиях не полностью определенной количественной информации, характерных для ранней стадии их исследования. Для оценки значимости объектов в работе используется их унарная оценка по линейно упорядоченным градациям дискретной шкалы, причем знание количественной ценности каждой градации не является необходимым. На основании разработанного метода вычисляется нечеткое обратимое бинарное отношение на множестве исследуемых объектов. Для окончательной упорядоченности исследуемых альтернативных вариантов – определения их количественной оценки – используется метод аппроксимации бинарного нечеткого обратимого отношения потенциальным нечетким отношением. Приведенный численный пример иллюстрирует эффективность предложенного подхода.

A large number of vehicles in cities has a significant negative impact on the environmental situation. Today, economic measures are actively applied to reduce the number of vehicles used with internal combustion engines, and new technical solutions are being introduced to reduce exhaust toxicity. However, the potential of these approaches to improving the environmental situation in cities is very limited and has already been almost fully realized. Therefore, the huge potential to minimize environmental damage, in an increasing number of vehicles in large cities, is to optimize the parameters of traffic flows. The key role here is played by the scheme of traffic light control, to the consideration of the optimality parameters of which this work is devoted.
