摘要
PURPOSE:To enhance flocculation efficiency of harmful polluting components of wastewater by preparing a flocculant mainly comprised of cultured strain of microbe having flocculant producing function and belonging to alkaligenese cupidas or treated one. CONSTITUTION:Polysaccharide is recovered from a cultured material after cultivation of a microbe belonging to alkaligenese cupidas KT 201 strain (FFRM P-10609) and having a flocculant producing function in a culture substrate. Using the polysaccharide as a flocculant, it is brought into contact with various kinds of polluting materials,various kinds of wastewater from industries, and water to be treated such as municipal sewage so as to flocculate, precipitate, and remove the pollutants and harmful components in the water to be treated. When an inorganic salt which produces acationic inorganic salt preperabaly polycation, more than univalent, such as calcium chloride, aluminum sulfate, magnesium sulfate, etc. is added to the flocculant, the flocculation effect is further improved.
