APPARATUS AND METHOD FOR TREATMENT OF WATER HAVING HIGH EFFICIENCY OF RECOVERING ORGANIC COMPOUNDS AND NUTRIENT BY USING MEMBRANE

摘要

A sewage disposal apparatus is provided to supply an anaerobic digester chamber in order to collect a methane gas, organic compounds, and nutritive salts efficiently by using a separation film. A sewage disposal apparatus comprises the following units. A pre-processing unit(20) removes impurities of sewage. A first separation film unit separates organic compounds and nutritive salts from pre-processed sewage. A second separation film unit separates the organic compounds and the nutritive salts from sewage which has passed through the first separation film unit. An anaerobic digester chamber discharges remaining organic compounds and nutritive salts.
