Environment-Friendly Technology of Airport’s Sewerage

Abstract

Several types of sewage waters are generated during airport functioning. They can be divided into industrial, domestic, and rain waters. It is known that 1 m 3 of discharged sewages, which have been not sufficiently purified, can result in a situation when from 10 to 50 m 3 of natural clean water becomes unsuitable for many types of usage. In [17], treatment technologies, employed at treatment plants, depend on sewage water types and their compositions and can differ substantially. Quality of treated waters can also differ depending on technology. Considerable amount of harmful sediments are created during all types of treatment processes. They also require to be utilized. In [2], at the same time, treatment plants are objects, where it is possible to get additional alternative energy sources and other valuable materials. Therefore, searching for environmentally friendly and energy-efficient ways to organize airport sewage systems is an actual task. 11.2 Research Methods There was a system approach applied while doing this research. The approach was used to analyze different methods of anaerobic digestion intensification and to form new technological requirements to digestion organization. The approach was also used to analyze highs and lows of conventional methods of microalgae cultivation and to form propositions to organize the cultivation more effectively. There were

Improving the photobioreactor operation efficiency in the technological scheme of wastewater treatment

“…2, a). Besides the above items, a diagram including a photobioreactor installed downstream of the secondary settler [37] can be recommended (Fig. 2, b).…”

“…They must be added to the culture medium [28][29][30]. To reduce the cost of cultivation and provide its higher ecological and economic efficiency, it is proposed to use mechanically purified municipal wastewater as cultural medium [31][32][33]. The wastewater can contain significant amount of nutrients, especially nitrogen and phosphorus compounds.…”
