摘要： PROBLEM TO BE SOLVED: To prevent the increase of disposal cost and the deterioration of the return material to the green and agricultural land, construction material, etc., by keeping the water content of treated sludge constant even when the sludge having the composition and concentration different from those of normal sludge is supplied as a large quantity of sediment flows in due to a heavy rain, and the composition of sludge is changed. SOLUTION: The proper discharge of sludge from a sludge treating device 4 is found by an arithmetic unit 7 based on the target water content of treated sludge and the concentration and flow rate of the sludge supplied from a sewage treating system obtained by a concentration meter 2 and a flow meter 3. When the proper discharge deviates from the actual discharge from the device 4, a control parameter correction is obtained by the arithmetic unit 7, and the concentration rate, drying time, etc., of the sludge treating device 4 are adjusted.

摘要： PROBLEM TO BE SOLVED: To preclude the invasion of a fibrous substance, contained in sludge, into a drying machine body by a method wherein a sludge supplying pipeline near the charging port of sludge for the drying machine body is provided with a filter while the filter is provided with a cutting member in the same. SOLUTION: A filter 17, having a cutting member in the same, is attached to the sludge charging port 8 of a drying machine body 2. Sludge is passed through the filter 17 and a sludge supplying pipeline 18 to supply the same into the sludge charging port 8 of the drying machine body 2. In this case, the filter 17 is formed of a metallic material, not corroded easily and having an elasticity, while the kind of filter is made changeable in accordance with the nature of the sludge. According to this method, the rotation of the drying machine will not be hindered or an air extraction passage will not be clogged due to the entangling of the fibrous material around the main shaft or the blades of the drying machine body 2 whereby the deterioration of drying performance can be prevented.

摘要： PROBLEM TO BE SOLVED: To effectively prevent the breakage of blades or the like and obtain the long life of the blades by providing buffer members for absorbing impact force due to the collision of sludge lump between the blades and a main shaft. SOLUTION: A main shaft 2 is provided with buffer members 21 made of an elastic material. The buffer member 21 is formed by connecting one end of a cylinder member made of a rubber to the surface of a metallc base. An attaching screw fixed to the back surface of the metallic base is detachably and threadedly attached to a tapped hole provided on the main shaft 2. The other end of the buffer member 21 formed in a gently spherical shape is opposed to the blade 6. The attaching position of the buffer member 21 is set to a position abutting on a position nearer to the end part of the blade 6 than to the center of gravity position of the blade 6. Since the buffer member 21 is soft, the waveform of impact force has a frequency component lower than the natural frequency of the bending of the blade 6. A stress waveform after collision rarely shows a vibration.
