Improvement of the biotechnology of wastewater treatment from livestock and poultry farms

Abstract

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.
