  • Publication number: 20150368130
    Abstract: A process for purification treatment of wastewater according to the present invention is a process for conducting a purification treatment of wastewater containing polyvinyl alcohol by using a membrane bioreactor process, the process including adding a nutrient to a treatment system. The nutrient is preferably added to an aeration tank. The nutrient preferably contains nitrogen. An amount of the nutrient initially added is preferably 5% or more and 25% or less in terms of nitrogen. The process for purification treatment of wastewater preferably includes a step of measuring a nitrogen content after a treatment, and an amount of the nutrient added is preferably adjusted on the basis of the result of this measurement while checking the effect on the basis of a chemical oxygen demand. The nutrient may be added to the aeration tank by a mechanism that adds the nutrient to the treatment system or by feeding the nutrient manually to the treatment system.

  • Patent number: 8100675
    Abstract: A fluid transporting device comprises a tube frame having a tube guide wall for arranging a tube having an elasticity in an arcuate shape, and a rotary pressure mechanism having a plurality of rollers. The rotary pressure mechanism is arranged, when the tube is arranged in the tube frame, on the side opposite to the guide wall side of the tube, such that its center of rotation is aligned with the center of the arc of the tube guide wall. A plurality of push pins are interposed between the tube and the rotary pressure mechanism and are arranged radially of the center of rotation of the rotary pressure mechanism. A switching mechanism moves at least one of the rollers to a position for the push pins to release the tube and a position for the push pins to press the tube.
