<p>PROBLEM TO BE SOLVED: To effectively remove suspended matters and oil-containing matters contained in waste water, to activate the biological treatment regardless of temp., to make the device compact by shortening the treatment time (cycle) and to transfer the device to a desired site. SOLUTION: Waste water from various sources supplied from a flow control tank 1 is continuously filtered by a waste-permeable sheet 4b, and the filtered water is heated to a specified temp., discharged into an anaerobic tank 12, then anaerobic biological treatment is activated, the material settled in the anaerobic tank 12 is retreated in a filtration tank 2, and the waste water is treated in a continuous flow. Consequently, the treating time is shortened, and the device is made transferable and compact.</p> |
