WETLAND AS POLLUTION CONTROL TREATMENT SYSTEM FOR AGRICULTURAL DRAINAGE

Abstract

Agriculture drains are fundamental in the analysis of water conditions in the Nile system. They receive municipal and industrial efiluents and discharge them into the River Nile. This increases the River Nile pollution loads, which requires treatment before discharging into the River Nile. This study has investigated the possibility of extending the application of aquatic treatment technology to achieve a certain reduction of the pollution loads discharging into the Nile. From a simple observation of the natural conditions in the agricultural drains in Egypt, it is clear that they are stocked with water hyacinth. The potential of application of the proposed methodology to the agriculture Saba! drain is evaluated under comprehensive field program along three stages. First stage was to present water quality conditions for the study area. The second stage was to perform field observation for six months of the natural aquatic treatment system (water hyacinth) found in the Saba! drain to study the use of aquatic plants in improving agricultural drainage water. Third Stage was to present a pilot field experiment for constructed wetland to adjust full-scale design of wetland area to locate it at the mouth of the drain and analyze the effect of this pilot experiment.
