Embodiment Construction

[0015] As shown in the figure, a two-way rheological spacing inclined plate sedimentation tank is adopted. The specific implementation method is as follows: the treated water enters the two-way flow sedimentation tank (1) through the water hole (10), and the two-way flow sedimentation tank (1) is provided with The diversion wall (9), under the action of the diversion wall (9), the treated water first settles in the large particle sedimentation area, and the treated water in this area will pass through the inclined plates (6) with large spacing in the same direction, so that the large particles Particulate matter removal; then the treated water enters the small particle settling zone, where the treated water will pass through the reverse flow small-pitch inclined plates (7), and the small particle matter is removed during this process. The inclined plate devices (6) and (7) are connected by connecting ribs (8). The sediment particles enter the sedimentation hopper (5) through t...

Abstract

The invention relates to inclined plate sedimentation equipment. In a sedimentation process applied in the field of water treatment, after an inclined plate sedimentation tank and an inclined plate sedimentation tank with small spacings operate for a period of time or when the water quality and the water volume are changed, sedimentation efficiency and effluent quality of the inclined plate sedimentation tank and the inclined plate sedimentation tank with small spacings are obviously reduced so as to cause serious mud accumulation and blockage between inclined pipes and inclined plates, even collapse of the inclined pipes and the inclined plates. A bidirectional flow variable-spacing inclined plate sedimentation tank comprises a bidirectional flow sedimentation tank, wherein the bidirectional flow sedimentation tank is divided into two parts by a guide wall; a first part is a same-way flow large particle sedimentation region; an included angle between each inclined plate and the horizontal plane in the same-way flow large particle sedimentation region is 45 degrees to 60 degrees; a second part is a reverse flow small particle sedimentation region; an included angle between each inclined plate and the horizontal plane in the reverse flow small particle sedimentation region is 55 degrees to 70 degrees; spacings between the inclined plates in the two sedimentation regions are different; the second part of the bidirectional flow sedimentation tank is provided with a water collecting tank; the tail end of the water collecting tank is provided with a water outlet pipe; and a sedimented sludge hopper and a sludge pipe are arranged on the lower surface of the bidirectional flow sedimentation tank. According to the invention, large and small particles are regionally sedimented, so that the problem of blockage between the inclined plates is avoided and sedimentation efficiency is high.

Description

Technical field: [0001] The invention belongs to the technical field of water treatment equipment and relates to an improvement of a water treatment inclined plate equipment. Background technique: [0002] In recent decades, advection sedimentation tanks have been widely used in my country. The structure of the traditional advection sedimentation tank is simple and easy to operate, the work is relatively safe and reliable, and the required level of operation and management is low; however, it occupies a large area and has low treatment efficiency. length. Since the 1970s, inclined tube sedimentation tanks have been widely used in water plants all over my country, and the sedimentation efficiency has been greatly improved. But after decades of application, its reliability is far less than that of the advection pool. This is mainly caused by the unreasonable structure of the inclined tube sedimentation equipment itself. The traditional sedimentation theory holds that the w...
