Introduction

Inclined tube sedimentation tank is designed under the condition of useful volume. Adding sedimentation area can improve the removal rate. The bottom of the multilayer sedimentation tank is inclined and separated horizontally to form a tube (rectangular or hexagonal). At an angle of 60° to the horizontal plane, it is placed in a sedimentation tank. The water moves from the bottom up, and the particles sink to the bottom of the inclined pipe. When the particles reach the design level, they automatically slide down, so that the solid particles in the sewage can settle. In the predetermined sludge area, the purpose of sewage purification is achieved. Compared with the advection sedimentation tank, the method has greatly improved the effect. From the analysis of improving the hydraulic conditions of the sedimentation tank, the hydraulic radius of the inclined tube sedimentation tank is greatly reduced, so that the Reynolds number Re greatly decreases, and the Froude number Fr greatly improves. Generally speaking, the water flow in the inclined tube sedimentation tank is basically a laminar flow condition, and Re is usually below 200, or even below 100. The inclined tube sedimentation tank satisfies the requirements of water flow stability and laminar flow. The introduction of the inclined tube sedimentation tank has enabled the shallow pond theory to be used in practice, and its effect is far better than the traditional sedimentation tank, and the sedimentation efficiency and land utilization rate have further improved.

Equipment characteristics

The tube deck settler media components should be installed close to each other, and there must be no gap between the front, back, left and right. It is common that there are gaps of several centimeters or even more than ten centimeters between the rows of some ponds after the end of the inclined tube device. This phenomenon is very harmful. First of all, the water from these gaps does not pass through the inclined pipe with good hydraulic conditions, and the flocs entrained in it are not easy to settle down, which adversely affects the water quality of the sedimentation tank. Secondly, the inclined tube is formed by sequentially bonding the plastic pieces that are restricted to form at an angle of 60°. After the design period is used, the plastic piece will lose its elasticity and become soft. As each piece of the inclined tube is bonded to the previous piece in sequence There is a design pressure. After the plastic is softened, when there is open space on both sides of the inclined pipe, the inclined pipe is expanded to both sides. The hole shape of the inclined pipe is changed from the original regular hexagon to the flat hexagon, and the inclination of the inclined pipe is also Gradually decrease, the smaller the inclination angle, the greater the pressure of each piece of the inclined tube on the previous piece, the flatter the shape of the hexagon, and the sludge will gradually occur in the inclined tube. The above phenomenon constitutes a vicious circle, so Will cause the inclined tube to fall, need to stop production and replace the inclined tube with a new one.

The raw materials used to make the inclined pipe include polypropylene, polyvinyl chloride, etc. Their specific gravity is generally less than 1, so there is a problem of anti-floating. Nylon rope is usually used to pass through the 90-degree angle of the oblique tube to fix it on the net bed. Although this method is simple, the disadvantage is that a funnel is formed at the entrance and exit of the rope, and a part of the orifice near it is kneaded. And blocked. The method of treatment is to be able to place a long Yuan steel with a diameter of mm along a line that fixes the inclined pipe. The nylon rope bypasses the Yuan steel at a design interval of 180 to fix the inclined pipe on the mesh bed, so that it will not form a funnel. Already. There are a plurality of grooves on the rod, and the measuring rod is pierced into the bottom of the pool and pulled out, and the mud in the groove can be used to know the depth of mud at that point.
