TECHNOLOGICAL FOUNDATIONS OF ENVIRONMENTALLY FRIENDLY ORGANIZATION OF A SEWAGE SYSTEM
Modern sanitary sewage systems, which apply traditional methods of sewage water treatment, not always can provide acceptable quality of treated waters for their environmentally safe discharge into water bodies. In addition, applied methods of sewage sludge utilization, which are produced during treatment processes, lead to substantial negative influence on environment. All of these things result in appearance of ecological risks, related to functioning of sewage systems. Because of this, there is a necessity for additional sewage water treatment and for improvement sewage sludge utilization methods. Virtues and shortcomings of modern methods of sewage water aftertreatment and sewage sludge utilization are analyzed in this paper. There is proposed a new arrangement of a sanitary sewage system. The system applies sewage water aftertreatment in photobioreactors by using the water as environment for energy microalgae cultivation and producing liquid biofuel of the third generation out of them. It also applies sewage sludge digestion in anaerobic installations with producing methane enriched biogas, environmentally safe organic fertilizer and carbon dioxide. There is also proposed to utilize carbon dioxide in photobioreactors for providing the process of photosynthesis. Bibl. 18, Fig. 1.
