Problems solved by technology

At the current stage, for the flocculation in the horizontal clapboard flocculation tank, the water flow at the bottom of the laminar flow is stable and cannot form more vortices, resulting in a low flocculation effect in the viscous area at the bottom of the corridor

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like figure 1 , 2 As shown in Fig. 3, a flocculation tank for enhancing the flocculation effect at the bottom includes n baffle spoiler components arranged in sequence along the length direction of the flocculation tank at unequal intervals. Each baffle spoiler assembly includes a handle 3, a connecting rod 4 and y baffles 5; wherein n=4, y=6. The connecting rod 4 is supported at the bottom of the flocculation tank, and its axis is parallel to the width direction of the flocculation tank (ie, perpendicular to the water flow direction). One end of the connecting rod 4 protrudes out of the flocculation tank, and a handle 3 is fixed. The y baffles 5 are welded and fixed on the connecting rod 4 at equal intervals in sequence. By rotating the connecting rod 4, the angle between each partition 5 and the flow direction of the water flow in the flocculation tank can...

Abstract

The invention discloses a flocculation tank for strengthening the flocculation effect at the bottom and a flocculation method thereof. The bottom of the flocculation tank is provided with a plurality of baffle spoiler components arranged in sequence along the water flow direction. Each baffle spoiler assembly includes one or a plurality of baffles arranged side by side. Along the water flow direction, the included angle between the baffle plates in each baffle plate spoiler assembly and the water flow direction gradually decreases. Compared with the traditional flocculation method, the invention adds a method of generating a vortex at the bottom to strengthen the flocculation effect, so that the flocculation efficiency is higher. In the present invention, in the direction from the water inlet to the water outlet, the spacing of different rows of baffles is in a trend from small to large, and the angle between the partitions and the bottom of the flocculation tank is in a trend from large to small, so that the flocculation tank produces a flow of water along the water flow direction. The large to small vortex not only increases the flocculation speed in the initial flocculation stage, but also avoids the large vortex to chop the flocs in the end stage of flocculation.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to a flocculation tank and a flocculation method for strengthening bottom flocculation effect. Background technique [0002] In the process of water treatment, coagulation is a very important link, which includes two stages, one is mixing and the other is flocculation. Flocculation refers to the aggregation of suspended particles in water or liquid, or the formation of flocs, thereby accelerating the coagulation of particles and achieving the purpose of solid-liquid separation. The quality of flocculation effect is mainly affected by the quality of raw water, the type and dosage of flocculants or flocculants added, as well as mixing conditions and flocculation hydraulic conditions. Among them, the hydraulic conditions are mainly determined by the structure of the flocculation tank. The clapboard flocculation tank refers to a structure in which the water flow passes between the clapboar...
