摘要：The present study is an attempt to have a comparative assessment of the efficiency of aquatic weeds like Typha latifolia, Eichhornia crassipes, Pistia stratiotes to treat the effluents from latex factory, in constructed wetlands. Ammonification of field latex, acid coagulation of skim latex and various chemical treatments during the production process of various products were found to be responsible for the high concentration of pollutants in this factory effluent. Phytoremediation for fifteen days by constructed wetland technology reduced the chemical oxygen demand, biochemical oxygen demand, pH, total solids of the effluent considerably.
