摘要： PURPOSE:To obtain a simple and inexpensive filter fabric running type electroosmotic and pressing dehydrator by providing an elastic film on one side of a filter room divided by a pair of filter frames, fitting electrically conductive materials each connected with an opposite electrode on each of the filter frame and arranging the filter material to only the cathode side in such a way that the electrically conductive material on the anode side on one of the filter frame is brought into direct contact with an original liq. CONSTITUTION:An elastic film 22 is provided on either one of filter frames of a filter room 24 between adjoining filter frames. In addition, electrically conductive materials 23 each connected with an opposite electrode are fitted on each filter frame and non-conductive filter material is arranged only on the cathode side in such a way that the electrically conductive material on the anode side on either one of these filter frames is brought into direct contact with an original liq. and direct electric current is energized between both electrodes. Then, when a sludge is fed, it flows into the filter room 24 and it passes through the filter fabric 10 and a filtrate is discharged. After a definite time, a pressurized water is fed to compress and dehydrate the sludge fed between the compression film 22 and the filter plate 8 side. Thereafter, a direct electric current is supplied between the electrically conductive plate 20 on the cathode side and the electrically conductive compression film 22 to perform electroosmosis dehydration.

摘要： PURPOSE:To reduce water content of a cake at a straight body part by forming a flooding hole which is located on the inner circumference of a dip weir and is punched through at a position on the side of a revolving axis from the edge of a clear liquid outlet outside a radius having a center in the revolving axis of the clear liquid outlet. CONSTITUTION:A solid layer is given a transporting force to the cake discharging side by a screw conveyor 3. At this time, since the solid layer goes through an interval between a first dip weir 32 and a revolving cylinder 2, the solid layer receives a high compacting pressure conversely. Therefore, what goes through the first dip weir 32 is only a heavy layer having higher concentration. The heavy layer having high concentration is to stay between the first dip weir 32 and a screw blade 30 on the left; on account of a centrifugal force received in between, separation between the heavy layer and a light layer is further accelerated, and the separated light layer is flowed through the flooding hole 32a to return to the side of a feeder opening 35. Thus, the compaction of the solid layer and the return of slurry with a high water content are performed, and thereby only the heavy layer portion is transported.

摘要： PURPOSE:To deepen the depth of a pool by installing a clarified liquid discharging hole in a ball head of a rotary ball, installing a ring dam in the outside of the ball head, and installing a clarified liquid discharging apparatus. CONSTITUTION:A liquid to be treated is supplied through a supplying tube 10 while a rotary ball 1 and a screw conveyor 2 rotate at a high rotary speed. The liquid to be treated flows in the rotary ball 1 through a supplying hole 15 of the screw conveyor 2 and splashes outside due to centrifugal force of the rotation of the rotary ball 1 so that a pool 14 is formed in the inner surrounding wall of the rotary ball 1. Solid matters in the raw liquid precipitate and are separated at the bottom of the pool 14 and separated from a clarified liquid. The solid matters are gathered by a screw blade 13 and discharged from a solid matter discharging hole 11. Consequently, the depth of the pool can be deepen and the consumption power is remarkably reduced and separation ability is improved.

摘要： PURPOSE:To estimate the water content of the dehydrated cake by recognizing the evaporation residue, coarse suspended matter, anion activity, crude protein, and org. component of the sludge when a cationic org. high molecular flocculant is added to org. sewage and the sludge is dehydrated by a dehydrator. CONSTITUTION:When a cationic org. high molecular flocculant is added to org. sewage and the sludge is dehydrated by the belt press type dehydrator, the evaporation residue, coarse suspended matter, anion activity, crude protein, and org. component of the sludge are recognized, and the water content of the cake is estimated by the equation obtained from the filtration rate, filter cloth speed, addition rate of a pressure flocculant which are given as the conditions along with the factors. In the equation, (y) is the water content (%) of the dehydrated cake, X1 is the evaporation residue (%), X2 is the coarse suspended matter (%), X3 is the anion activity (meq/g-TS), X4 is the crude protein (%), X5 is the org. component (%), X6 is the addition rate (%) of the flocculant, X7 is the filtration rate (kg-ds/m-H), X8 is the filter cloth speed (m/min), and X9 is the pressure (kg/cm ). Consequently, the dehydrated cake can be estimated with sufficient pertinence without operating the actual machine.

摘要： PROBLEM TO BE SOLVED: To make effective utilization of sewer sludge and to obtain an extremely effective admixture by using the molten slag powder of the sewer sludge. SOLUTION: The molten slag of the sewer sludge of 5 to 30 μm in average grain size is used. This admixture is obtd. by mixing 1 to 60 pts.wt. admixture with 100 pts.wt. cement. The admixture is obtd. by subjecting the sewer sludge to a melting treatment, then to pulverizing. More particularly, the admixture is obtd. by heating the sewer sludge generated in a sewer treatment plant to 1,100 to 1,600 deg.C to pyrolyze and burn the org. component and to melt the inorg. component, then rapidly cooling the melt in water or slowly cooling the melt in air to obtain the molten slag of the sewer sludge, then pulverizing the slag with, for example, a ball mill. The admixture is the molten slag powder of the sewer sludge which is not hollow and is solid. The mortar or concrete added with the admixture is capable of assuring a high flow property even at a low water-cement ratio and is free of a drastic degradation in an air- entraining quantity. The generation of heat in the initial period of curing is low and the mortar or concrete is hardly crackable.

摘要： PURPOSE: To obtain an electrode function for improving water dischargeability with a high strength by a method wherein a porous electrode plate is made of a carbon fiber reinforcing carbon material having a specific gas permeability, a fiber volume content and a porosity. CONSTITUTION: The carbon fiber of an anode electrode plate 4 having no filter cloth is made of lint in a porous form having a gas permeability of 0.1-10cm / sec, a porosity of 25-40% and a fiber volume content of 30-55% by a method wherein the lint is prepared, laminated, impregnated with a resins capable of carbonization such as a phenol resin and an epoxy resin and carbonized and baked at about 1000-3000 deg.C. In the dewatering using the carbon fiber, sludge is forcibly fed from a raw liquid entrance opening 9 into a filter chamber 3 and is filtered through a carbon fiber reinforcing carbon material and the liquid is discharged from a filtrate exit opening 10 to outside. On the cathode side, the sludge is filtered through filter cloth 8, sent through a cathode side electrode plate 6, a diaphragm 5 and a filtrate hole 7 and discharged from a filtrate exit opening 11 to outside. The dewatering efficiency can be improved by an electroendosmotic action after pressurized water is sent between the diaphragm 5 and a filter plate 2 to expand the sludge.

摘要： PURPOSE:To increase separation capacity and to prevent deterioration of capacity due to generation of a vortex by fitting a plurality of separation plates which are tilted for the lines radiated from a shaft center in a cylinder and provided in the radial directions while keeping the intervals in the lengthwise direction of the title separator to a supprting body fixed to a screw shaft. CONSTITUTION:Centrifugal force acts on liquid to be treated in the annular space and particles are relatively pushed to the radial directions. At this time, some particles are shortly allowed to collide against the surfaces of the correspondent separation plates 50 and thereafter flow down to the edge sides along inclination and flow out because the separation plates 50 are tilted for the radial lines. Further the edge sides of the separation plates 50 are separated from the plates 50 and the partition plates 41 in the circumferential direction because of the circumferential thickness of a supporting member and therefore the particles are passed through the separated parts and pushed to the inner surface of a cylinder 10. By such a way, the particles which have been separated from liquid and deposited near the inner surface of the cylinder 10 are continuously discharged as heavy phase substance W1 through an outlet 12a by the screw blades 22. On the other hand, clarified liquid separated from the particles is discharged as light phase substance W2 over a weir 13 while holding the liquid level L.
