Efficient sewage sedimentation treatment device

Abstract

The invention discloses an efficient sewage sedimentation treatment device. The efficient sewage sedimentation treatment device comprises a sedimentation box, a water inlet pipe, a water outlet pipe and a sludge box, wherein the sedimentation box is internally provided with a tapered cavity; the water inlet pipe is arranged at the left end of the sedimentation box; a central pipe is arranged at the position of the central axis of the tapered cavity; the upper end of the central pipe is connected with an output shaft of a driving motor through a transmission belt; a spiral blade is fixedly connected with an outer wall of the central pipe; an overflowing pipe, which is distributed in the circumferential direction, is arranged at the outer side of the central pipe. According to the efficientsewage sedimentation treatment device disclosed by the invention, the tapered cavity, the central pipe, the spiral blade, the overflowing pipe and a flocculating agent filling mechanism communicated with the central pipe are arranged, so that efficient mixing of sewage and a flocculating agent is realized; meanwhile, efficient separation of impurity particles is realized, and the sewage sedimentation and impurity removal efficiency and the sedimentation effect are improved; a sludge box and a stopping block are arranged and precipitated sludge is stored, so that a condition that the sludge israised under the action of water flow is avoided.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage high-efficiency sedimentation treatment device. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields are also increasingly entering the daily life of ordinary people. Sedimentation is required in the sewage treatment process. The traditional sedimentation tank adopts an open design. By adding flocculant, the flocculant and sewage are mixed through a single stirring mechanism, and then naturally settle under the action of gravity. The stirring structure is not very good. The flocculant is mixed with the sewage and the natural sedimentation efficiency is low, and...

Sedimentation is required in the sewage treatment process. The traditional sedimentation tank adopts an open design. By adding flocculant, the flocculant and sewage are mixed through a single stirring mechanism, and then naturally settle under the action of gravity. The stirring structure is not very good. The flocculant is mixed with the sewage and the natural sedimentation efficiency is low, and the treatment cycle is long. In addition, it is very troublesome when cleaning the sludge, and continuous sedimentation operations cannot be carried out.
