Abstract

The ability of aquatic plants to absorb heavy metals and reduce their concentration in the WASTEWATER flow is shown in many studies. However, due to its low cost and adaptability of this technology, it is considered by many experts. MERCURY is one of the most dangerous metals, which can be found in some industrial WASTEWATER. In this study, MERCURY uptake by four species of DEZFUL endemic aquatic plants include PHRAGMITES australis, TYPHA latifolia, Scirpus bulrush and Alisma plantgo were evaluated and identified two sufficient species. After selecting the appropriate species, the effect of system type (containing two aquatic plants and control system) and reten on me (1, 3, 7, 10 and 14 days) on the MERCURY REMOVAL EFFICIENCY on pollu on level of 100 mg/kg Hg in soil was studied. For this purpose, first through the pot experiment, soil was polluted by three different levels of MERCURY (50, 100 and 200 mg/kg Hg in soil) in 60-day period and plants were cultivated. This part of experiment was performed in a completely randomized design with three replications. The results showed that two plant species PHRAGMITES australis and TYPHA latifolia, measuring 6.23 and 2.23 mg/kg Hg in dry material of plant underground tissues showed the highest accumulation of MERCURY. There were significant differences in the rate of MERCURY accumulation in aboveground and belowground tissues. The two species selected at previous stage were cultivated at constructed pond with a size of 5 m length, 0.5 m wide and 0.4 m depth which they were isolated. A drainage pipe was places at the end of ponds for outflow of WASTEWATER. A pond as a control (without plant) was considered also. These tests also formed a completely randomized design with three replications. The results showed that the HRT and type of system on REMOVAL EFFICIENCY of MERCURY were significant, but interaction effect of these two factors was insignificant.
