ASSESSMENT THE FACULTY OF JATROPHA CURCAS L. ON WASTEWATER TREATMENT OF NATURAL RUBBER

Abstract

Environmental pollution treatment is nowadays one of the most interested subjects in many countries and the treatment of wastewater of natural rubber has to be taken in priority. At the moment, there are many available technologies set up and operated for treatment wastewater of natural rubber. However, the effluent quality is still poor and the concentration of pollutants is higher than the required national technical regulation on the effluent of the natural rubber processing industry (QCVN 24:2009/BTNMT). Thus, this research used the phytoremediation method for wastewater treatment of natural rubber.  The phytoremediation is an emerging technology that uses various plants to degrade contaminants from soil and water. The phytoremediation is simple, lowly costs and friendly with the environment. It is currently used in many countries over the world. Our research cultivated Jatropha curcas in wetland with natural rubber wastewater. The results indicated that temperature were not significantly different among treatments. The temperature varied form 28 – 32.5^oC; the pH from 4,3 – 7,1. The treatment efficiencies of COD, BOD, N-NH₃ and SS were 46.5%; 46.1%; 66.3%; 61.09%.
