Problems solved by technology

However, the spiral flocculator cannot be flexibly adjusted according to the flow and velocity of the water flow, and the flocculation effect is not ideal
[0007] It can be seen that the flocculation equipment on the existing market is relatively old, and many parameters are designed according to the previous water quality conditions, and the flocculation equipment cannot be flex...

Abstract

The invention discloses a flocculating basin with arc blade vortex generators and a flocculating method thereof. A design scheme for solving the problems that a flocculating device cannot be flexibly adjusted, and a flocculating constituent in the flocculating process is prone to being shredded is in urgent need at present. A flocculating basin body is divided into n+1 galleries and one settling pond, and the multiple arc blade vortex generators are arranged in all the galleries except for the gallery close to a settling partition plate. The flocculating method comprises the steps that raw water and a chemical flow into the flocculating basin body after being mixed in a coagulation pipe and passes through the galleries in a turbulence and vortex mode to enter the settling pond through guiding hole sets of the settling partition plate, and the flocculation is constantly accumulated and finally deposited at the bottom of the settling pond; blade angle adjusting devices are constantly adjusted, treated water samples are collected at an outlet to carry out water turbidity measurement, and blade deviation angles matched with the turbulence flow and the flow speed are acquired. The rotating angles of arc blades around a center shaft can be adjusted according to the water flow and the flow speed, and therefore the water flow vortex degree and intensity can be adjusted, and the flocculating process is promoted.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a flocculation tank with a vortex generator with arc-shaped blades and a flocculation method thereof. Background technique [0002] Humans have been treating water for quite a long time. The agglomeration of suspended particles in water or liquid, or the formation of flocs, accelerates the coagulation of particles and achieves the purpose of solid-liquid separation. This phenomenon or operation is called flocculation. Usually, flocculation is implemented by adding an appropriate flocculant, whose function is to adsorb particles and "bridge" between particles, thereby promoting agglomeration. [0003] The particle size of suspended matter and limb matter in natural water is very small. In order to remove these substances, coagulation is usually used, that is to say, an appropriate coagulant is added to the raw water, and after thorough mixing, the stability o...
