Problems solved by technology

Although it is currently the best separation device for sediment, suspended solids and water, it is not 100% perfect objectively, and there are also some shortcomings: for example, the co-current flow is forced to distribute water, the technical difficulty is high, and the water collection is uneven, so it has been eliminated; Widely used counterflow separation, the rising flow direction of the water flow is opposite to the sinking direction of the suspended particles, so the settling process of the suspended particles (alum flowers) must be disturbed by the impact of the rising water flow to cause pulsation, which affects the sinking separation and sinking speed. Affects mud-water separation
Both mechanical flocculation and / or hydraulic flocculation require power consumption, and the water vortex flocculation generated by violent movement is not uniform, and the quality of sediment flocs formed is poor, which affects the flocculation effect
[0010] The above-mentioned prior art shows that: although the mud-water separation inclined plate or inclined tube, as well as clarification or sedimentation, have been invented for nearly a hundred years, and people have continuously improved it, but the inclined plate or inclined tube has a single function, and the only one is the one-way settling function. Objectively, the efficiency and effect of mud-water separation are still not the best; mechanical flocculation and hydraulic flocculation need to consume power, and violent movement produces water vortex flocculation unevenness, which affects the flocculation effect
The above basic shortcomings have not been effectively resolved, so there is still room for improvement

Embodiment 1

[0033] Embodiment 1: see figure 1 , the oblique pipe for mud-water separation of the present invention prepares the hexagonal honeycomb oblique pipe according to the similar prior art, suppresses the positive trapezoidal wave plate 2 of wave height 3mm, adjacent wave width (wave spacing) 200mm, directly opposite with adjacent and relative wave plate ( The troughs and crests are relatively non-staggered and opposite to each other) 35mm apart from each other and positioned adjacent to the space, and in the space according to the upper and lower intervals of 35mm, separate slant strips 3 with an inclination of 60 degrees (the trapezoidal wave plate is also inclined at 60 degrees vertically), the slant strips The lower side is in the shape of a square wave zigzag, forming an inclined tube 1 with two-way shallow separation.

Embodiment 2

[0034] Example 2: see Figure 2-4 , The clarification or sedimentation device of the present invention consists of two parts, the front flocculation reaction zone 6 and the rear clarification zone 9 according to the flow process, and the depth of the pool is 3.8m. The flocculation reaction zone 6 is adjacently divided into three reaction zones with approximately equal volumes. At the bottom of each flocculation reaction zone, there is a triangular mud collecting bucket 7, a built-in mud discharge pipe 8 (gravity mud discharge), and a mud discharge valve 12 outside. Each area is separated by a partition to form a water turn-back flow. A flocculation reaction grid is arranged on a metal frame with φ10mm nylon ropes 14 and 15 orthogonally woven into a square grid with a hole edge of 55*55mm. 5. The height of each single-layer grid 13 is 10mm. The upper and lower spacing of each layer grid in the first reaction zone is 80mm, the upper and lower spacing of each layer grid in the s...

Abstract

The invention relates to the improvement of a separation inclined pipe and a clarifying / precipitating device for clarifying and precipitating in a water treatment process, which is characterized in that parallel opposite wave plates which form an inclined pipe are oppositely and adjacently arranged at intervals; the adjacent space is provided with separated inclined plate strips which are arranged up and down at intervals; and the water inlet and outlet of the inclined pipe and the separated inclined plate strips are parallel or approximately parallel. Compared with the mud-water separation of an incongruous flow of the existing inclined plate and inclined pipe, the inclined pipe provided by the invention has higher surface load, higher mud-water separation efficiency and better mud-waterseparation effect and can effectively separate tiny suspended matters which can not be precipitated and separated originally, the quality of the separated water is better, the muddy matters are removed completely, and the treatment is more stable. The clarifying / precipitating device provided by the invention can enhance the efficiency by above 30% and can obviously improve the water quality. The invention adopts grid turbulence flocculation, can be beneficial to improvement of the quality of the clarified / precipitated water and can realize basically powerless flocculation. The separation inclined pipe and the clarifying / precipitating device provided by the invention can be used for clarifying in various water supply treatments and recycled water treatments and for precipitating in sewage treatment.

Description

technical field [0001] The present invention is an improvement to the separation inclined pipe for clarification and precipitation of water treatment process and clarification / sedimentation device, especially relates to a kind of inclined pipe for mud-water separation with larger hydraulic surface load, higher separation efficiency and better separation effect, and This is the clarification / sedimentation device mainly composed of. Background technique [0002] Clarification of water supply treatment, reclaimed water reuse treatment, etc., or water treatment precipitation, its function is to make the fine suspended particles in the water sink as soon as possible and effectively to realize separation from water. The surface hydraulic load and the density of sludge particles are mostly used to fill separation inclined plates or inclined pipes in clarification or sedimentation tanks to form counterflow sludge water separation clarification or sedimentation. The inclined plate o...
