AUTONOMOUS PLATFORM COLLECTING THE VEGETATION IN EXCESS FROM NATURAL RESERVATIONS LAKES USED AS A FUTURE BIOMASS RESOURCE

摘要

In Romania, near the Black Sea are two Natural Reservations lakes with salt water, Techirghiol, and Mangalia nowadays confronted with new environmental issues. Lake never freezes. Under these conditions, there are always birds in transit or in wintering; some of them protected species as endangered. There are no known or available solutions at present that can be used here, without disturbing the biological balance. This paper presents a prototype, patent pending in Romania, which has achieved significant results in protection of the natural environment. The prototype is an autonomous pilot station, placed on a mobile pontoon, powered by photovoltaic panels. It can collect and partially dry the aquatic vegetation developed in excess due to eutrophication. The harvested vegetation is used as the biomass resource to warm the Research Centre on shore, the greenhouse for the protected plant species and the poultry incubator. The prototype now is implemented in Techirghiol Lake as to diminish the local environmental problems: the massive mass of vegetation, the invasive species that appeared, as the invertebrates, the interference scallops, and the predator fish. Due to the permanent decreasing the number of the specific fish, all bird colonies are affected. The proposed solution is innovative, perfect ecological and energetic independent. The mobile pontoon is commanded from distance. The solar panels ensure the pontoon movement and the supply of the collecting, compacting, and partially drying the vegetation. The detailed functioning of the prototype is further detailed presented. The main advantage of this solution is that the vegetation can be collected during the entire period of vegetation without disturbing the biologic environmental, nests period of construction, laying eggs, rearing birds, etc. A second major advantage is that the extracted vegetation can be consumed immediately and integrally into a biomass power plant. The third advantage of this technology is that the platform is placed on a mobile pontoon energetically independent, entirely automated and with a constant adaptation of the operating parameters in accordance with climatic conditions. This innovative solution is accordance to the Romanian reply for EU Council Directives, UE EUCO 75/13 CO EUR 7 signed in Brussels at 22/05/2013, referring to the promotion of the new solutions based on utilization of renewable technology with environmental effects. The prototype has a multi- and a cross-disciplinary character due to the main components. It represents a powerful applicative research requested and co-financed by the National Authorities and the private sector, as to solve this problem appeared into these Natural Reservations.
