Biological treatment of water
专利汇可以提供Biological treatment of water专利检索，专利查询，专利分析的服务。并且PURPOSE: To separate easily solid from liq. without necessitating a deposited medium in a biological membrane method by bringing water to be treated into contact with pelletal composite particles obtained by adding zeolite mineral powder and an org. high molecular flocculant to a suspension of microbes previously cultured.
CONSTITUTION: A powdery or finely powdered zeolite mineral or activated carbon is added to a suspension of microbes previously cultured and then an org. high melucular flocculant is added. The mixture is agitated, flocculated and granulated to form pelletal composite particles of microbes and an adsorbent. The pelletal composite particles are charge into a biological treating vessel and brought into contact with water to be treated aerobically or anaerobically. Consequently, solid and liq. separation is facilitated in an activated sludge process. Moreover, a microbe-deposited medium can be dispensed with in a biological membrane method. Accordingly, microbes which are poorly adhesive to a medium can be adsorpted. Furthermore, a microbe immobilizing method suitable for easy production and mass production on an industrial scale can be provided.
