专利汇可以提供Method for recovering valuable material from organic waste liquid专利检索,专利查询,专利分析的服务。并且PURPOSE:To recover with reduced time and equipment by acid-fermenting the organic waste liquid under high liquid pressure while supplying an oxygen-contg. gas, and then recovering the valuable materials with a selective permeable membrane. CONSTITUTION:The high-concn. organic waste liquid such as the waste liquid from foodstuffs is supplied into a deep tank-shaped bioreactor 2 from a supply passage 1, and circulated successively through a downward flow passage 2a, an upward flow passage 2b, and a pump flow passage 2c while blowing an oxygen- contg. gas such as air into the downward flow passage 2a by a blower B and nozzle 2d. Accordingly, organic acids such as acetic acid, propionic acid, and butyric acid are formed from the organic materials in the waste liquid. Then the liquid is sent into the first membrane separator 3 and the second membrane separator 4 to recover the organic acids.,下面是Method for recovering valuable material from organic waste liquid专利的具体信息内容。
