چکیده
Wastewater treatment in semi-natural systems, such as a hydroponic lagoon operating the third stage of treatment, is becoming more and popular because efficiency organic matter nutrient removal. The article presents an analysis pollutant removal at mechanical-biological wastewater plant Gronów with capacity Q<sub>d</sub> = 1125m<sup>3</sup>/day load 9375 PE. operates on basis activated sludge biomass settling technology submerged flow beds. characterized by very high variability inflow during year due to periodic from tourist resorts Łagów. average removing pollutants was: BOD<sub>5</sub> - 98.5%, COD 92.8%, total suspended solids 93.2%, nitrogen 86.1% phosphorus 69.5%. study showed that use technological system improved 1.7% for BOD<sub>5</sub>, 0.9% COD, 4.3%, 6.4% phosphorus- 3.3%.

Investigating the efficiency and kinetic coefficients of nutrient removal in the subsurface artificial wetland of Yazd wastewater treatment plant
Background: Investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. The advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. Th...
متن کاملPAHs in wastewater: removal efficiency in a conventional wastewater treatment plant and comparison with model predictions.
Polycyclic aromatic hydrocarbons (PAHs) are very hazardous compounds and, owing to their lipophilicity, they can easily cross biological membranes and accumulate inside organisms, causing damage to the genetic material. The scientific interest in PAHs is related to their demonstrated or supposed genotoxicity (cancer-causing characteristics of B[alpha]Py and dB[alpha, h] first suspected in the 1...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Removal of selected organic pollutants in anaerobic wastewater treatment process
Aromatic compounds belong to one of most widely distributed classes of organic substances used in industry, services and households and, therefore they are relatively often measured in municipal wastewater. Their efficient biological degradation is essential to reduce the subsequent disposal of such substances into the waters of the receiver, or release into the atmosphere. The mineralization o...
