Cambered solid-liquid separation sieve filter basin for water treatment

Abstract

The invention relates to a water treatment device, in particular to a cambered solid-liquid separation sieve filter basin for water treatment. The middle of the rectangular filter basin is provided with a high weir wall (102) erected from the bottom, the rear side is provided with a water inlet tank (100), and the front side is also provided with a short weir wall (801) erected from the bottom; apure water collecting tank (700) is arranged between the short weir wall (801) and the high weir wall (102); the front side of the short weir wall (801) is provided with a sewage collecting tank (800); the bottom of each tank is provided with a pure water outlet (701), a water inlet (101) and a sewage outlet port (802); a plurality of rectangular cambered sieve plate brackets (600) with concave surfaces facing upwards are arranged in parallel between the high weir wall (102) and the short weir wall (801); the frame is provided with a slot (601) into which a cambered sieve plate (500) with theconcave surface facing upwards is inserted; an overflow weir plate bracket (300) is fixed on the top of the high weir wall (102); and one side of an overflow weir plate (200) with the concave surfacefacing downwards is connected to the overflow weir plate bracket (300) through a hinge (201), and the other side is tightly buckled on the upper edge of the cambered sieve plate (500). The turnable overflow weir plate ensures that the cambered sieve plate can be pulled out of the cambered frame and replaced, and can be used for adjusting the height of the water level in the water inlet tank, thereby satisfying the demands for debugging a culture system.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a separation sieve filter pool structure used in the occasion where solid-liquid separation is required for water bodies. Background technique [0002] With the rapid development of our country's economy, the pollution and destruction of the ecological environment of water areas are becoming more and more serious, and the water areas are facing the serious threat of ecological desertification. The existing production mode is restricted, and the closed circulation water breeding system is gradually rising in our country. At present, my country's Guangdong, Sichuan, Shandong, Xinjiang, Fujian and other places have successively built industrialized recirculating aquaculture workshops. The water treatment equipment of the circulating water system ensures the water quality requirements for fish reproduction, realizes the reuse of water bodies, has the advantages of low water resource requi...

AI Technical Summary

Problems solved by technology

The filter equipment of the existing industrial circulating aquaculture system has disadvantages such as complex structure, large floor space, noise, high maintenance cost and high energy consumption. With the cultivation of industrial circulating water, such problems have become increasingly prominent and urgently need to be solved
