Title: Water collection/drainage trough
Inventor: SUEHIRO BUNICHI
IPC: B01D19/00
Filed: 2001-02-28
Abstract: 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.
