The inclined tube sedimentation tank refers to a sedimentation tank with inclined tubes in the sedimentation area.There are two types of assembly forms: inclined pipe and branch pipe.The sedimentation zone of the horizontal or vertical flow sedimentation tank is divided into a series of shallow sedimentation layers by inclined parallel pipes or parallel pipes (sometimes honeycomb packing can be used), and the treated and settled sludge is in each sedimentary shallow layer. move and separate from each other.Introduction According to the direction of their mutual movement, it is divided into three different separation methods: reverse (different) flow, co-current flow and lateral flow.Every two parallel inclined plates (or in parallel tubes) is equivalent to a very shallow sedimentation tank.The advantages are: ①Using the principle of laminar flow to improve the processing capacity of the sedimentation tank; ②Shortening the sedimentation distance of particles, thereby shortening the sedimentation time; ③Increasing the sedimentation area of the sedimentation tank, thereby improving the processing efficiency.The flow rate of this type of sedimentation tank can reach 36m3/(m2.h), which is 7-10 times higher than the processing capacity of ordinary sedimentation tanks. It is a new type of high-efficiency sedimentation equipment.And has been finalized for production practice.Advantages: high removal rate, short residence time, small footprint.Design parameters (1) The spacing between the inclined plates (tubes) is generally not less than 50mm, and the length of the inclined plates (tubes) is generally about 1.0-1.2m; (2) The upper layer of the inclined plate should have a water depth of 0.5-1.0m, and the bottom should be buffered Floor height is 1.0m.The waste water distribution area is under the inclined plate (pipe), and the height is generally not less than 0.5m, and the lower part of the water distribution area is the sludge area; (3) Multi-row perforated pipes are generally used to collect water for the effluent of the pool, and the perforations should be 2cm below the water surface to prevent Floating matter is taken away; (4) The flow rate of waste water in the inclined pipe depends on different waste water, such as domestic sewage treatment, the flow rate is 3-5mm/s.(5) The inclined plate (pipe) is at an angle of 60° with the horizontal plane, and the clear distance of the inclined plate (or the diameter of the inclined pipe) is generally 80-100mm.
