Description
Technical Field
The invention belongs to the technical field of water treatment equipment, and relates to a winding type sedimentation tank.
Background
Under the action of gravity, the structure for separating suspended particles in water is a sedimentation tank. In the water treatment process, after mixing and flocculation, suspended particles in water form floccules with larger particle sizes and need to be removed in a sedimentation structure. Even if the water source is relatively clear throughout the year, a precipitation structure is required to be built to remove the turbidity in the water in order to adapt to the characteristic of increased turbidity after rain. Under normal conditions, the sedimentation tank can remove more than 90% of suspended matters in water, and the effect of removing suspended solids by filtering in the filter tank is superior to that of removing suspended solids by filtering in the filter tank.
Different types of settling tanks differ in their construction, but the principle of separating suspended particles is essentially the same. Vertical sedimentation tanks, horizontal sedimentation tanks and radial sedimentation tanks are generally available. The water flow in the vertical sedimentation tank moves upwards, and the suspended particles move downwards, so that the particles with the sedimentation velocity higher than the water flow velocity are mainly removed, the surface load is small, the occupied area is large, and the application of the sedimentation tank is directly limited. The water flow in the radial flow sedimentation tank flows to the periphery from the center of the tank, the horizontal flow velocity is gradually reduced, and the settled impurities are precipitated to the bottom. The sedimentation tank has large floor area, relatively complex structure and poor effluent uniformity. Therefore, the method is mostly used for pre-settling treatment of high-turbidity water or sewage treatment with low effluent turbidity requirement. Therefore, the horizontal flow sedimentation tank is mostly used at present.
The horizontal sedimentation tank has the advantages of early application, wide application range, simple structure, stable performance, certain impact load resistance, high removal rate and convenient management after construction. However, the horizontal sedimentation tank has large floor area, uneven water distribution and discharge, complex flow state of water flow, and the effect of removing suspended particles is often influenced by the structure of the tank body and external conditions, so that the current land resources are increasingly tense, the requirements of people on the quality and quantity of domestic water are gradually improved, and the application of the horizontal sedimentation tank is limited to a certain extent.
In 1904, Hazen proposed shallow pool theory: under the condition of a certain volume of the sedimentation tank, the shallower the tank is, the larger the sedimentation area is, and the higher the removal rate of suspended particles is. A tube/plate settler was thus developed: the settling zone of a horizontal or vertical flow settling tank is divided into a series of shallow settling layers by inclined parallel pipes or parallel pipes (honeycomb packing is sometimes used), and the treated and settled sludge moves and separates from each other in each settling shallow layer. The pipe chute sedimentation tank treatment effeciency is high, and the rivers flow state is stable, and area is little, has compensatied the shortcoming of advection sedimentation tank to a certain extent, nevertheless, because dwell time is short, its buffer capacity is poor, requires highly to thoughtlessly congealing, and because the structure reason of pipe chute sedimentation tank itself, the length and the inclination of its pipe chute swash plate of itself are difficult to balance: the longer the inclined plate inclined tube is, the smaller the inclination angle is, and the higher the sedimentation efficiency is. However, the inclined plate and inclined tube are too long, the manufacture and installation are difficult, and the improvement of the settling efficiency by increasing the length to a certain extent is limited; the smaller the inclination angle is, the more difficult the sludge discharge is, the microorganisms are easy to form a film on the filler, the influence on the effluent quality is caused, and the danger of collapse is accumulated in every day and month. Maintenance and management are very cumbersome.
Aiming at the problems, the invention provides a novel winding type sedimentation tank which can obviously solve the problems of large floor area of a horizontal flow type sedimentation tank, difficult sludge discharge of an inclined tube inclined plate sedimentation tank, complex management and the like so as to improve the quality and the efficiency of water treatment.
