Abstract

The invention provides a spiral type circular flow sewage flocculation tank, which comprises a first spiral flute shaped tank body, a second spiral flute shaped tank body, an adjusting tank and a sand filter, wherein the adjusting tank and the innermost ring of the first spiral flute shaped tank body are connected through a water-adjusting pipe; a water-adjusting pipe is also connected between the innermost ring of the second spiral flute shaped tank body and the sand filter; the ports of the outermost rings of the two spiral flute shaped tank bodies are connected into a whole; the lower part of the adjusting tank is provided with a water inlet pipe which is provided with a drug feed opening; the insides of the two spiral flute shaped tank bodies are provided with an aeration pipe respectively; and the top of the sand filter is provided with a water outlet pipe. The spiral type circular flow sewage flocculation tank adopting the spiral flute shaped tank bodies increases the length of water flow in certain floor space, prolongs the sewage treatment time, and has the characteristics of simple structure, large sewage processing quantity, small occupied space, high treatment efficiency, difficult blockage, stable running, low cost, and strong impact resistance.

Description

technical field [0001] The invention relates to a sewage treatment flocculation tank, which belongs to the technical field of sewage treatment. Background technique [0002] The sewage purification process is first to add flocculant to the sewage for adsorption. The flocculant agent is mixed with the sewage, and the particles in the sewage are basically completely absorbed. After the adsorption treatment, the water enters the sedimentation tank for precipitation. This technology requires the construction of a large-area flocculation tank, which occupies a large area, has high operating costs, and the purification effect is not ideal. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a spiral circulation sewage flocculation tank with simple structure, high treatment efficiency and small occupied area. [0004] The present invention adopts following technical solutions: [0005] The spiral circulating sewag...
