PROCESS OF WASTEWATER TREATMENT USING POST-ANAEROBIC STEP AND PHOTOSYNTHETIC STEP OF ALGAE

摘要

PURPOSE: A waste water treatment process is provided, which is characterized in that a post-anaerobic step and a photosynthetic step of algae for the removal of remaining salts are added in conventional process. CONSTITUTION: Remained organic substances which are treated by anaerobic bacteria will be disintegrated in an anaerobic digester(11). Organic salts which are made in the anaerobic digester(11) will be absorbed by a photosynthesis tank(12) using algae. Gas which is produced by the anaerobic digester(11) and the photosynthetic tank(12) will be exhausted by a ventilator(13). These sediments will be precipitated and separated in a separation tank(14) and concentrated in a concentration tank(16). The sludge will be stored(17), condensed, settled(15), and filtered(18). The method using anaerobic bacteria like nitrosomonas, nitrobacter will disintegrate organic substances and absorb organic salts using photosynthetic process to improve water quality.
