- Abstract
Several intensive flow-through fish production plants were established in Hungary in the last decades, representing a significant share of the total fish production. However, the full management of the discharged waste from such systems is still unsolved. Searching new sustainable methods for treatment and utilisation of output nutrients a pilot-scale constructed wetland system was built in Szarvas in 2000. The pilot-scale system consisted of two subsystems (total area of 1.4ha) of similar structure: one stabilisation pond and one fishpond connected serially; the water was channelled from the fishpond into macrophyte ponds (surface-flow wetlands) and additionally spread on one irrigated field. The nutrient removal of the wetland units was most efficient in the case of organic carbon in the subsystem "A"; for all nutrients the removal efficiency reached 90%, except for the phosphorus in the "A" subsystem, where the lowest efficiency was found (80%).
