Abstract

The invention provides a mechanical flocculation basin. The flocculation basin can reduce generation of a stagnant water zone by making a vortex so as to improve the flocculation effect. The flocculation basin comprises a tank body, a water inlet and a water outlet, the tank body comprises a first-stage tank, a second-stage tank, a third-stage tank, a fourth-stage tank and an outlet tank which are sequentially connected, a vertical double-layer stirrer is vertically arranged in the first-stage tank, the vertical double-layer stirrer comprises a first stirring blade and a second stirring blade, the first stirring blade comprises a cross-shaped rod and a stirring rod mounted on the cross-shaped rod, and the second stirring blade comprises a hinge stirring blade and a stirring disc; the interior of the second-stage tank is divided into more than one stirring chamber by an upper folded plate and a lower folded plate which are alternately used, a gap is formed between the upper folded plate and the bottom of the tank body, a gap is formed between the lower folded plate and the top of the tank body, and a horizontal stirrer which is horizontally arranged is mounted in each stirring chamber; a micro-vortex flocculator is arranged in the third-stage tank; a grid flocculator is arranged in the fourth-stage tank; and a honeycomb straight pipe filler is arranged in the outlet tank.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a mechanical flocculation tank. Background technique [0002] The flocculation reaction process in the industrial and domestic water supply treatment process is a unit purification process centered on the formation of flocs, and its effect is determined by the chemical action of the flocculant and the physical action of the flocculation reaction facility. In the original rectangular reciprocating flocculation tank, there are generally dead water areas. The existence of dead water areas not only easily forms sediment accumulation, but also seriously hinders the movement of water flow. The flocculation effect is not good, and finally the quality standard of water treatment cannot be met. Contents of the invention [0003] Aiming at the problem that the traditional flocculation tank will have dead water areas affecting the flocculation effect, the present invention provide...
