Ensuring water supply and sewage management are among the primary tasks of every commune, and they are also the condition for multi-functional de-velopment of rural areas. Positive changes in the area of providing communes with the basic water mains-sewerage infrastructure mean an improvement in the living conditions for the population and for the functioning of companies. For many years intensive work has been going on in Poland, aimed at ensuring a suitable status of the environment, especially in rural areas where still a lot needs to be done in this respect. At the end of the 20th and the beginning of the 21st centuries numerous water supply and sewerage systems have been built in those areas, as well as many household and collective sewage treatment plants. One of the provinces where the largest number of household sewage treatment systems have been built is the Lublin Province. The technological most frequently applied here include systems based on the use of a septic tank and filtration drainage, systems with a biological bed or active sludge, as well as hybrid systems (biological bed + active sludge). Less popular, on the other hand, are constructed wetland systems, probably because their construction requires plots with ...
The paper presents issues concerning the construction and commissioning of a constructed wetland wastewater treatment plant on the example of an object, which was established in 2011 in the village Skorczyce (Lublin province). It was found that the costs of constructing this type of treatment plant pay for itself after about 5 years of operation. Calculated that the cost of materials accounted for 65% of the total investment costs incurred for the installation of the object. The remainder (about 35%) were the costs of services relating to the design and im-plementation of treatment plant and supervision of its construction and commis-sioning. In the first months of treatment plant operation was over 95% efficiency of the elimination of organic pollutants (BOD5 and COD) and total suspended solids removal. Optimum conditions for removal of pollutants were observed in the first bed with vertical flow. During start-up treatment plant the average total phosphorus removal efficiency was 84% and total nitrogen did not exceed 42%, which may be due to inadequate formation of biological membranes and unfavorable conditions for the normal processes of nitrification and denitrification.
