Search and development of non-waste and environmental technology solutions of bioconversion of manure and waste water, providing extraction of valuable nutrients additional feed for livestock and poultry, as well as allowing to reduce (or eliminate) the discharge of wastewater into the environment is an important direction of development of modern science, which is of crucial economic and social importance. The purpose of the research was to improve the biotechnology of wastewater treatment from livestock and poultry farms. The problem of protection of water objects from contamination by surface wastewater from the catchment area of livestock and poultry farms has been considered by the authors of the article. A new methodological approach to protecting the environment from waste pollution consists in minimizing wastewater discharges to theoretically achievable limits; using drinkingquality water exclusively to ensure technical and sanitary conditions for the normal functioning of livestock farms; full utilization of off -balance water directly at the farms. The implementation of the strategic goal should be translated into a waste-free water supply for all enterprises in the industry. No waste water discharge – there is no problem of land and water contamination. A new technology has been developed for the treatment of manure-containing and litter-containing waste water. The researches has been confi rmed the possibility of using modern biotechnologies for the treatment of contaminated wastewater from livestock and poultry farms. The use of an accumulative phytofi lter is an eff ective method of protecting water ecosystems from contamination by surface wastewater from catchment areas of livestock and poultry farms. The proposed construction provides not only environmental friendliness of the technology, but also naturally fi ts into the landscape of the area.

During the operation of poultry farms a large amount of poultry manure is accumulated. Surface wastewater from landfills for storing poultry manure can become the main source of pollution of natural waters. Thus, one of the most important problems of environmental protection is the development of effective systems for protecting aquatic ecosystems from pollution by waste water generated at landfills for storing poultry manure. The purpose of research was the analysis of water protection systems for treatment of surface wastewater from the territory of poultry farms. The authors of the article consider the problem of protection of water bodies from contamination by surface wastewater from the catchment area of poultry farms. The example of surface wastewater from the catchment area of the poultry farm “Sverdlovskaya” has shown the negative impact on water ecosystems. Our own studies of snow contamination from the catchment area of the poultry farm have shown a high content of not only organic and biogenic substances, but also heavy metals. A biotechnology of wastewater treatment using natural ion-exchange materials, followed by bioregeneration of the latter by higher aquatic vegetation, has been developed. The use of an accumulative phytofilter is an effective method of protecting water ecosystems from contamination by surface wastewater from catchment areas of poultry farms, and the design ensures not only the environmental friendliness of the technology, but also naturally fits into the landscape of the area.

Currently, there is no a generally accepted classifi cation of the sorbents used in the technologies for wastewater treatment from oil products. The purpose of this work is to more fully systematize the sorbents used in wastewater treatment, depending on their main characteristics, as well as on the economy and environmental friendliness. Based on the existing classifi cations, the generalized classifi cation of the sorbents designed for wastewater treatment from oil products in the dissolved and emulsifi ed forms, and additionally in the fi lm form, was developed and supplemented with the new parameters. A special algorithm, that allows one to make an informed choice of the sorbent in terms of its application effi ciency, environmental protection and material costs, is formed. In this regard, as an example, the classifi cation of pine sawdust has been performed. It can be considered as an eff ective sorbent base.

The presented study examines the concepts of “environmental marketing” and “environmental product”. The study attempts to conceptualize these terms in Russian language with allowance for the concept of sustainable development and the principles of the circular economy.Aim. The study aims to develop the conceptual foundations of environmental marketing and its derivative — environmental product, laying the groundwork for future research in specifying the concepts of “environmental marketing” and “environmental product”.Tasks. The authors examine the current state of environmental marketing and environmental product in Russia in terms of legislation and market practices; analyze the evolution of these concepts in foreign and Russian publications; systematize experience in this field; provide an original conceptualization of these terms; operationalize their key characteristics and features.Methods. This study is based on qualitative empirical research using such methods as content analysis, synthesis, formalization, and systematization. The theoretical and methodological approach of the study is based on the works of foreign and Russian scientists in the field of environmental marketing, the “green” approach to the promotion of goods, and sustainable enterprise development.Results. A research gap in the conceptualization of “environmental marketing” and “environmental product” in Russian language is identified. The authors provide an original interpretation of these concepts with allowance for the principles of sustainable development and “green” promotion.Conclusions. This study serves to elaborate on the scientific meaning of the concept of “environmental friendliness” applicable in marketing, changing the trend of the increasing number of products that fall under the definition of greenwashing. The published materials can be useful for environmental consultants, marketers, and representatives of legislative authorities in certifying products according to environmental standards.

Water is the basis of natural resources and strategic economic resources.Deteriorated water environment of streams in Shenzhen city could have a great impact on ecological safety, people's health,and economic development.Based on the data of field observation and Remote sensing (RS) image,integrated analysis of the water degradation causes,and the changes of biochemical oxygen demand in five days(BOD5)concentration by mathematical model were carried out,which is on basis of percentage of waste water disposal,fresh water transformation,and harbor excavation, respectively.The results show that degradation causes of water quality were resulted from waste water discharge, harbor construction,and ecological environment damage, which could lead to slowly water exchange. Accordingly,the pollution can be easily to store in the bay,which result in water quality changes.The most important improved countermeasure is the control of waste water, which could be had a great effectiveness to decrease pollution.In addition, fresh water must be supplied after polluted water was cut off,which can be better improvement for water quality.This would be extreme improvement for hydrological dynamics due to 15m harbor excavation,which can significantly reduce BOD5 concentration.The innovation points of this paper is to mathematical model,which is based on the basis of qualitative analysis.

What makes for a good scientist or a good engineer? How does using a new technology or working in a research lab begin to shape our thought and behavior? How can we best anticipate and navigate the ethical dilemmas created by modern scientific research and technology? Scholars across multiple disciplines have begun turning to a surprising resource to address these questions: discussions of virtue that have their roots in ancient philosophical and religious traditions. This volume gathers a number of these perspectives to show how concepts of virtue can help us better understand, construct, and use the fruits of modern science and technology.
