RESERVOIR ET PROCEDE DE TRAITEMENT ET DE PURIFICATION D'EFFLUENTS

摘要

The treatment tank (T) for purification of effluent, comprises compartments (1, 2, 3, 4, 5, 6) traversed by the effluents to be treated along a horizontal axis of organic filter elements. The effluents pass over the three types of organic filter elements, which include a first type of organic filter element (7) constituted of natural vascular plant, hollow fiber stem, sub-species of Bambusoideae, grass species and stems (12, 13, 15) that are provided by internal and external diagonal slits in which colonies of photosensitive self-sustaining microorganisms grow, react and multiply. The treatment tank (T) for purification of effluent, comprises compartments (1, 2, 3, 4, 5, 6) traversed by the effluents to be treated along a horizontal axis of organic filter elements. The effluents pass over the three types of organic filter elements, which include a first type of organic filter element (7) constituted of natural vascular plant, hollow fiber stem, sub-species of Bambusoideae, grass species and stems (12, 13, 15) that are provided by internal and external diagonal slits in which colonies of photosensitive self-sustaining microorganisms grow, react and multiply to form a retention chamber, a second type of organic filter element constituted of stems of same vascular plant cut into pieces and a third type of organic filter element constituted of stems of the same vascular plants, which are trimmed and transformed into carbon (14, 16). The microorganisms have the function to filter and digest the organic matter to be treated. The first compartment allows the effluent to be treated and contains the first organic filter element of which the stems are arranged horizontally and fill the tank at the base leaving 22% free space of the compartment for micro-organisms to proliferate. The second compartment receives the effluent obtained from first compartment, and is filled with first and second type of organic filter elements, which occupy 22% of internal space of the compartment. The third compartment receives effluent obtained from the second compartment, and is filled with the first type of organic filter element of which the stems fill the tank leaving 22% of free space at the bottom of the compartment. The fourth compartment receives effluent from the third compartment, and is filled with the first and third type of organic filter elements, which are placed at the bottom of the fourth compartment and occupy 22% of its internal space. The fifth compartment receives the effluent from the fourth compartment, and is filled with first and second type of organic filter elements, which are placed at the bottom of the fifth compartment and occupy 22% of its internal space. The sixth compartment receives the effluent from the fifth compartment, and is filled with first and third type of organic filter elements, which are placed at the bottom of the sixth compartment and occupy 50% of its internal space. An independent claim is included for a process for treating and purifying an effluent.
