PURPOSE:To efficiently produce a microbial flocculant by sending a part of waste water such as agricultural, livestock and fishery waste water to the culture equipment provided at its discharge place and cultivating the microbes belonging to rhodococcus with the culture medium using the waste water. CONSTITUTION:The waste water 5 generated when fishes 2 are processed into marine products 4 is sent to a waste water treating plant 6, a part of the waster water is sent to the culture equipment 7 in the plant 6, and the remainder is set to a solid separation process 8. A culture medium for producing a microbial flocculant is prepared by using the waste water 5 delivered to the culture equipment 7 in the process 9 for cultivating and producing the microbial flocculant, the microbial flocculant producing bacteria belonging to Rhodococcus or Nocardia are cultivated with culture medium, and a microbial flocculant is produced. The culture soln. 10 from the process 9 is added to the other waste water in the solid separation process 8, the waste water is left standing, and solid is separated. |
