摘要： PROBLEM TO BE SOLVED: To provide a water collection/drainage trough which is a small-sized trough and yet, capable of realizing appropriate solid-liquid separation and water collection/drainage and can be installed with improved workability and used in expanded application fields. SOLUTION: In this trough (shown in the figure), when a liquid containing solid matter B overflows an overflow wall 6d, a downwardly oriented stream of the liquid is formed between the overflow wall 6d and a side wall 6c, due to the obstruction of movement of the liquid toward the side of a main body 6a by the side wall 6c and then, when the downwardly oriented stream reaches a lower wall 6b, the solid matter B is subjected to solid-liquid separation by allowing the solid matter B to move along the slope of the lower wall 6b, and allowed to fall through the space between the lower wall 6b and the overflow wall 6d and recovered. Also, the separated liquid by the solid-liquid separation is passed through the space between the side wall 6c and the lower wall 6b to form an upwardly oriented stream of the separated liquid between the side wall 6c and the main body 6a. Thereafter, the separated liquid is allowed to flow over the wall of the main body 6a into the inside of the main body 6a, due to the obstruction of movement of the separated liquid toward the side of the overflow wall 6d by the side wall 6c, and collected and then, the collected liquid is passed through the inside of the trough and finally drained. Thus, by using the trough, the solid-liquid separation of water and collection/drainage of the separated water can appropriately be performed, and concurrently, by integrating the main body 6a, lower wall 6b, side wall 6c and overflow wall 6d into an integral body, the water collection/drainage trough is made compact and can easily be installed, and further, by arranging such troughs in parallel, these troughs can also be applied to a large-size pond or the like.

摘要： PROBLEM TO BE SOLVED: To satisfactorily dehydrate a matter to be dehydrated to a prescribed water content in a short time by a simple configuration and without using a coagulant. SOLUTION: Gravity dehydration by a filter cloth 15 and suction dehydration from below by a sucking means 17 are performed to the matter to be dehydrated charged on the filter cloth 15. Moisture at the surface side of the matter to be dehydrated which takes long to be dehydrated by the gravity dehydration and the suction dehydration, is absorbed and retained by a capillary action caused by the contact of a sponge-shaped water retention body 26 to the surface of the matter to be dehydrated. The contact of a portion which does not retain water to the matter to be dehydrated is attained at any time by separating the sponge-shaped water retention body 26 from the matter to be dehydrated and making it going around, which enables good water absorption and good water retention. The contact and the separation of the sponge-shaped water retention body 26 to the matter to be dehydrated is performed by the movement of only a part (24A) of rolls 24 (24B, 24C) over which the sponge-shaped water retention body 26 is laid across and spread.

摘要： PROBLEM TO BE SOLVED: To provide a water purification equipment excellent performance to remove the solid content attached to the surface of a membrane element as well as capable of sufficiently preventing damages on the surface of the membrane element, and a method for cleaning the membrane element. SOLUTION: The water purification equipment 1 is provided with a treating tank 11 to which a water to be treated is supplied, a flat membrane 33 which is immersed in the water W to be treated to obtain a treated water by the membrane filtration of the water to be treated, a bubbling equipment 25 generating air bubbles 3 in the treating tank 11 and a floating solid 2 capable of floating on a gas-liquid interface in the treating tank 11. At the time of cleaning a flat membrane 33, the solid content attached to the surface of the membrane is efficiently cleaned by transferring the gas-liquid interface within a range between both up and down ends of the flat membrane 33 and vibrating the floating solid 2 to strongly rub with the flat membrane 33. The damages on the surface of the membrane are prevented because the floating solid 2 comes into contact with the surface of the membrane only at the time of washing.

摘要： PURPOSE:To easily release a cake layer in a short time and to apply this method to any kind of membrane module by moving a gas-liq. interface in a treating tank over the whole region between the upper and lower ends of the membrane face of a membrane module and generating bubbles in the treating tank. CONSTITUTION:A membrane module 15 dipped in the water W to be treated in a treating tank 11 to filter the water W to obtain the treated water is cleaned as follows. Namely, a gas-liq. interface in the treating tank 11 is moved over the whole region between the upper and lower ends of the membrane face of the module 15, and bubbles are generated in the tank 11. In this case, the air injected into the tank forms bubbles to produce a diffused-air current, and the membrane face of the module is vibrated with the current to release a cake layer. Since the bubbles burst at the gas-liq. interface, the make-up water at a high flow velocity is irregularly moved vertically, and the membrane face is strongly rubbed by the make-up water. Accordingly, the cake layer is more effectively released, and the cake layer is easily released.

摘要： PROBLEM TO BE SOLVED: To provide a filtration membrane cleaning method by which a filtration membrane can be cleaned effectively. SOLUTION: This filtration membrane cleaning method comprises a filtering step to dissolve gas in the pressurized raw liquid and filter the gas-dissolved raw liquid 1 by a filtration membrane 2, a decompressing step to decompress the raw liquid 1 and a backwashing step to backwash the membrane 2. At the decompression step the gas 3 dissolved in the raw liquid 1 becomes minute air bubbles 5, which are then adhered to the surface of a turbidity causing material 4 stuck to the surface of the membrane 2 to perform a function to separate the material 4 from the membrane surface. At the backwashing step the material 4 separated at the decompression step can be removed easily from the membrane surface.

摘要： PROBLEM TO BE SOLVED: To provide a furnace performance testing method capable of obtaining performance testing data having reproducibility and high reliability. SOLUTION: The furnace performance testing method contains a process wherein wet pulp having a specified moisture content is incinerated in a furnace. The wet pulp is decreased in a heat generating amount by wetness and when its heat generating amount is reduced to a value approximately equal to that of a wet combustible substance and the wet pulp forms a substitution incinerating material. By preparing the wet pulp such that it has a specified moisture content, a substitution incineration material having a specified heat generating amount corresponding to a given content can be obtained any number of times without selecting a timing and a place.
