Valea Ierului (Érmellék) has 150.000 residents. In other specialists’ opinion the region of Valea Ierului (Érmellék) does not include Carei, Tasnad and other localities, as the number of the residents did not exceed 77.000 inhabitants. As there are more concepts related, we have to choose one of them. Therefore, we consider that Valea Ierului (Érmellék) is a region that has 80 localities and 77.000 inhabitants. The largest localities are the following: Carei (with 45.000 inhabitants), Marghita (Margita – 29.000 inhabitants), Valea lui Mihai (Ermihalyfalva – 21.000 inhabitants), Tăsnad (Tasnad – 20.000 inhabitants), Sacuieni (Szekelyhid – 18.000 inhabitants), Diosig (Bihardioszeg – 9.000 inhabitants), and on the Hungarian region border, Letavertes (12.000 inhabitants). Figure 1: The map of Valea Ierului (Érmellék) (Veliky J, 2005) The natural structure of Valea Ierului (Érmellék) The region is characterized - as it is situated in the middle of the Carpathian basin – by a continental climate and by some fluctuations of the temperature, though the average value does not pass 10°C. According to the measurements made at the Sacuieni Meteorological Station in 1996 the average precipitation wasn’t more than 800mm. The value of the atmospheric pressure is not more than 1000 milibar, the number of sunny hours are approximately 2000, and this fact indicates the equality of the number of sunny and cloudy hours. The surface water system of Valea Ierului (Érmellék) is composed by three rivers. The most important river is the Ier (Ér), which crosses the area from the north-east side towards south-west. The other rivers are Crasna (Kraszna) in the north and Barcău (Berettyó) in the south-west. The Valea Ierului (Érmellék) of our days is not the same with the one from the 40’s. In those times the region was a marshy, swampy area with a rich biodiversity, many floral and fish species. Some specialists considered that in that time the region could compete with the biodiversity from the Danube’s Delta. The flora was 600
characterized by marshy plants like the common reed, sedge and the rush. These plants are also present today, but unfortunately in a small number. Related to the characteristics of the soil we have to mention that in this area we can find chemozem, but the oxygen poor soils with an important content of clay are dominating the area (general characteristics of the marshes). The sandy soil can also be found in some places, but that is not characteristic. Wastewater treatment with constructed wetlands The wastewater purification with constructed wetlands is not a very new water cleaning technology. It has already been used since the 60’, when some German scientists discovered the purification capacity of the natural wetlands, and after that the idea of wastewater cleaning with plants was spread all of the word. Nowadays, in Hungary many systems like that are working and their efficiency is really high. The reduction of P, NOx, NH3, K, metals, phenols and other elements can compete in many cases with the classic wastewater treatment systems. The wetlands are very successful wastewater purification systems all over the world, and they are very various. They can be characterized by many criteria, as their genesis, location, functioning. By their genesis wetlands can be: • Marshes • Bugs • Flood area • Marginalized wetlands • Periodic wetlands From another point of view they can be natural or artificial wetlands, lakes or marshes, and some of them are complex piped systems, with a surface or a subsurface flow. In these complex systems the input wastewater generally enters in the pipe lines flowing through under the root zone of the plants (generally common reed), and after that is evacuated in the nature. At this time the water has to be cleaned and purified. The technology that is going to be used depends on the situation of the villages, the number of residents, the composition and quantity of the wastewater, external factors as climate, type of the soil and many other factors. The origin of the wastewater is another criterion that has to be taken into consideration in order to select the suitable methods, because there is a significant difference between the wastewaters coming from communal, industrial or agricultural use. The system of constructed wetlands is based on the absorption process of the pollutants by the emergent, submersed and floating plants, using the biofilters created under the water surface, and in that way the toxic elements are going to be eliminated from the water. There exist more physical, chemical and biological processes that make the treatment efficient. These processes generally are the following: sedimentation, filtration, adsorption and absorption, biological decomposing, and there are many other processes that assure together a complex purification. 601
