Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] The structure of the floating decanter in this embodiment is as figure 1 As shown, the water collection weir channel 1 adopted is a straight weir channel with a U-shaped section, and a triangular weir plate 2 is installed at the weir mouth. The drain outlet at the bottom of the water collection weir groove 1 is connected with a drain hose 3, and the other end of the drain hose 3 is connected with a drain bottom cylinder 14 installed at the bottom 16 of the pool. According to the difference of the decanted water amount and the size of the decanter, the pipe diameter and quantity of the drain hose can be adjusted appropriately, and there are 5 drain hoses 3 in the pr...

Abstract

The invention belongs to the technical field of drainage equipment for sewage treatment, and particularly relates to a buoyancy water decanter of which the working state is similar to the working state of a secondary sedimentation tank effluent weir. The buoyancy water decanter comprises a catchment weir notch and a control device, wherein the catchment weir notch floats on the water surface; thecontrol device is used for controlling the water inflow depth of the catchment weir notch; the bottom of the catchment weir notch is provided with a water outlet; and the water outlet is connected with a drain pipe. The water decanter adopting the technology is simple and reliable to operate and control and is stable to operate. The situation that effluent is mixed with sludge can be greatly reduced. According to the buoyancy action, the water decanter floats on the water surface, so that the integral water decantation of the water decanter is even and stable, and thus the weir length of the water decanter can be lengthened as much as possible.

Description

technical field [0001] The invention belongs to the technical field of drainage equipment for sewage treatment, in particular to a buoyancy decanter close to the working state of the outlet weir of a secondary settling tank. Background technique [0002] At present, with the widespread application of Sequencing Batch Activated Sludge Process (hereinafter referred to as SBR) sewage treatment process, the water outlet method needs to meet the requirements of intermittent water outlet according to the operation cycle (stop water outlet during aeration reaction). In order to meet this requirement, domestic and foreign manufacturers have developed various decanters, the main types of equipment are: [0003] 1. Rotary decanter [0004] This type of decanter relies on a mechanical push rod to push the decanter standpipe, driving the decanter weir down, and draining the pool water out of the pool. This type of decanter is most commonly used in China. Its advantage is that it uses ...
