Abstract :

The operation of fish ponds washing increases the risk of using these wastewater in drip irrigation by raising the amount of suspended solids and organic matter in the wastewater. In this paper, three drip irrigation treatments were performed. For each treatment, Netafim and Microflapper emitters were used with 4, 8 and 12 l/h discharges. During a season, 42 irrigation events were conducted with conventional water (as control) and fish farming effluent (with depletion and without depletion of tubes). Several samples were collected from wastewater, in the usual mode and in washing the fish ponds, in three replicates. The physical, chemical and biological properties of all samples were measured and compared. The filtered materials by sand and grid filters of the control and wastewater systems were analyzed by Master Sizer device. The results showed that washing has a significant effect on the concentration of suspended solids (p < 1%) and the concentration of organic matter (p < 5%). But the effect of washing on the concentration of nitrate and the number of bacteria in the wastewater is small and negligible. The results also showed that the discharge of 8 L/h Microflopper emitters had a significant correlation (p < 1%) with pond washing in both effluent treatments, and the discharge rate of Microflapper emitters was more correlated with the washing operations compared to the Netafim emitters. The results also showed that the efficiency of grid filters are more than sand filters when fish farm effluent is using, and the presence of these filters is more necessary.
