摘要： PROBLEM TO BE SOLVED: To provide an external circulation type fluidized incinerator and its operating method capable of measuring a height of a sand layer interface of a lower seal chamber of a downcomer, regardless of an operating condition of a furnace. SOLUTION: This external circulation type fluidized incinerator provided with a cyclone for separating fluidized sand, comprises the fluidized sand downcomer 4 for connecting cyclones 3 and a fluidizing part 13 for circulating the separated fluidized sand to the fluidizing part 13, and a sealed chamber 5 communicated to the fluidizing part 13, at a lower part of the downcomer 4. A laser beam level meter 17 is mounted to detect the height of the sand layer interface in the sealed chamber 5 by irradiating the laser beam in the vertical direction, or in a state that an angle to the vertical direction is within a range of an inclination angle θ to the horizontal direction of the seal chamber sand layer interface. A sheath pipe 18 having a diameter more than an outer diameter of the laser beam is mounted on the laser beam level meter 17 by the total length of the beam (flux of light) part from the laser beam emitting part to the sane layer interface height or its partial length part, and the sheath pipe 18 preferably has an air supply pipe for supplying the air for purging, inside thereof.

摘要： PROBLEM TO BE SOLVED: To provide a water treatment method and apparatus which can improve separation performance and maintainability for water treatment, and can perform efficient filtration using a separation membrane.
SOLUTION: This method carries out water treatment by the filtration using the separation membrane 3. The separation membrane 3 is made of vinyl chloride-based resin and/or chlorinated polyethylene to which hydrophilicity is given. The filtration is carried out while maintaining the concentration of a membrane surface contamination preventing agent in water to be treated or membrane permeate of the separation membrane within a range capable of preventing the propagation of microorganisms. It is desirable that the separation membrane has such a permeability that pure water flux at an operating pressure of 0.1 MPa is equal to or larger than 5 m
3 /m
2 /day (at a water temperature of 25°C). The separation membrane can be made of a material with hydrophilicity derived by adding a compound with a hydrophilic group to vinyl chloride-based resin or chlorinated polyethylene and reacting them with each other. The separation membrane is a hollow fiber membrane, and it is desirable that tensile breaking strength per one hollow fiber is equal to or larger than 3.5 N.
