Problems solved by technology

However, in actual production and application, due to the difference in flow section between the clear water area and the inclined plate area of ​​the inclined plate (tube) sedimentation tank, the flow velocity difference between the two areas is caused, and the large alum flower particles move relative to the water in the sedimentation to form a vortex. Both caused the pulsation of the water flow, making it difficult to remove small particles and affecting the quality of the effluent water.
When the distance between the inclined plates is too small, it is easy to form a floc layer covering the entire inclined plate on the upper surface of the inclined plate. In addition, it is also a technical difficulty that the inclined plate is blocked by sediment at the bottom of the inclined plate.
Therefore, small-pitch slant plates are basically no longer used

Abstract

The invention relates to a multistage sloping plate water treatment device which comprises a precipitating pool, a sloping plate group, a mud precipitating hopper, a mud discharge pipe, a water distributing device and a plurality of water collecting grooves, wherein the sloping plate group is arranged on the mud precipitating hopper of the precipitating pool; the water collecting grooves are arranged on the sloping plate group; the mud discharge pipe is arranged at the bottom of the mud precipitating hopper; the water distributing device is arranged on the side wall of the precipitating pool below the sloping plate group; and the sloping plate group comprises a plurality of sloping plates and a steel bar for fixing the sloping plates and is fixed between the left side wall and the right side wall of the precipitating pool by the steel bar. The multistage sloping plate water treatment device is characterized in that the sloping plates for forming the sloping plate group are one or more of long sloping plates, middle-length sloping plates and short sloping plates. The invention has the advantages of good discharge water effect and obvious reduction of particle content of discharge clear liquid; aiming at raw water of surface water, the treatment effect can reach 1NTU; and the surface load is about two times of that of conventional equipment and reaches more than 15m<3>/m<2>.

Description

technical field [0001] The invention relates to a multistage inclined plate water treatment device, which belongs to the technical field of solid-liquid separation. technical background [0002] The main disadvantage of the conventional water treatment inclined plate (pipe) sedimentation equipment currently used is that it is difficult to remove small particles in the effluent of the sedimentation tank, resulting in high turbidity of the effluent of the sedimentation tank, and the sedimentation tank has poor shock load resistance. This is because the traditional sloping plate (pipe) equipment is developed based on the shallow pool theory. This theory believes that the fluid in the sloping plate sedimentation space is a laminar flow, and reducing the distance between the sloping plates can suppress turbulent flow and shorten the sedimentation distance. , to improve the water discharge effect. However, in actual production and application, due to the difference in flow sectio...
