Abstract

The invention discloses a purification device for primary sewage treatment. The purification device comprises a water inlet platform, a purification barrel and an impurity filter tank, wherein the inner wall of the water inlet platform is connected with an auxiliary stirring mechanism; the auxiliary stirring mechanism comprises a connecting block, bulging teeth, side teeth as well as an upper guide plate and a lower guide plate which are obliquely mounted; the bottom of the water inlet platform communicates with one side of the top of the purification barrel. When sewage is mixed with a flocculating agent, the sewage and the flocculating agent produce continuous collision contact and spirally downward force during flowing under the gravity effect, the contact area between the sewage and the flocculating agent is enlarged, the mixing effect and efficiency of the sewage and the flocculating agent is improved substantially, the sewage and the flocculating agent can be further stirred spirally and mixed more sufficiently within a short time, and the mixing effect of the sewage and the flocculating agent is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a purification device for primary treatment of sewage. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. In sewage treatment, flocculant is needed to assist, and in the primary treatment of sewage, sewage and flocculant need to be fully mixed before the impurity filtration step is carried out. [0003] Nowadays, in the purification devices for the primary treatment of sewage on the market, the mixing time of sewage and flocculant is long, and most of them are carried out in the form of...
