Clarification tank with submersible reflux pump composite micro-vortex reaction process

Abstract

The invention discloses a clarification tank. On a basis of a micro-vortex flocculation technology, a device which can form sludge circulation is adopted, such that advantages of traditional water processing processes can be preserved, and defects thereof can be made up. Therefore, an optimal treatment effect can be achieved. According to the clarification tank with the submersible reflux pump composite micro-vortex reaction process, the tank comprises a tank body structure. A central cylinder is arranged at the center of the tank body. A water inlet pipe is arranged at the middle-lower part of the tank body. The bottom of the tank is provided with a gentle slope and a sludge discharge pipe. The central cylinder comprises a reaction first zone and a reaction second zone. The reaction first zone has a tapered cylindrical shape. The reaction second zone is welded on the periphery of the reaction first zone. The bottom of the reaction second zone is annular and is manufactured with steel. The inner ring is welded with the reaction first zone, and a concrete peripheral cylinder is sealed on the outer ring. Micro-vortex flocculators are filled in the reaction first zone and the reaction second zone. A flow guide device is arranged on the bottom of the side of the reaction second zone. An umbrella-shaped plate is arranged below the flow guide device. A submersible reflux pump is arranged on the bottom of the reaction first zone. A multi-point water distribution system is also arranged at an end of the water inlet pipe.

Description

technical field

[0001] The invention belongs to the technical field of water treatment, and in particular relates to a clarifier adopting a submersible reflux pump and conforming to a micro-vortex reaction process. Background technique

[0002] The coagulation treatment process of water and wastewater includes three stages: mixing of water and chemicals, reaction and separation of flocs and water. The clarifier is a special equipment that completes the above three processes and integrates them. The medium used to trap and separate impurity particles in the clarifier is suspended sludge. In the clarifier, the sediment is lifted and placed in a uniformly distributed suspension, forming a high concentration of stable active sludge layer in the tank. The raw water flows from bottom to top in the clarifier, and the sludge layer can be in a dynamic equilibrium state in the rising water flow due to gravity. When the raw water passes through the activated sludge layer, using ...

Embodiment 1

[0029] Such as figure 1 As shown, the clarification tank using the submersible reflux pump compound micro-vortex reaction process includes the structure of the tank body 1, and the central cylinder 2 is arranged in the middle of the tank body 1. The central cylinder 2 should be located at the geometric center when looking down on the tank body 1, and the deviation is not greater than 0.1 m, made of steel plate. The central cylinder 2 is divided into a first reaction zone 21 and a second reaction zone 22. The first reaction zone 21 is in the shape of a conical cylinder, and the periphery of the first reaction zone 21 is welded with a second reaction zone 22. The second reaction zone 22 is cylindrical, and its bottom is Made of annular steel, the inner ring of the second reaction zone 22 is welded to the first reaction zone, the outer ring is sealed with a concrete peripheral cylinder 23, and both the first reaction zone 21 and the second reaction zone 22 are filled with micro-v...

Embodiment 2

[0039] As a preferred solution of the present invention, other technical features are the same as in Embodiment 1, the difference is that the bottom of the pool is also laid with a small mud discharge pipe 18 that discharges mud upwards along the gentle slope to the outside of the pool, and the small mud discharge pipe 18 is added to play a role. The role of auxiliary mud discharge ensures that the part where the submersible return pump is located will not be silted up by sediment and affect its heat dissipation.
