Problems solved by technology

[0003] The vast majority of township domestic sewage treatment processes follow the treatment process of urban sewage plants, but these treatment processes cannot effectively adapt to the characteristics of township domestic sewage; domestic sewage is different from industrial production sewage, with low harmful substances and does not contain a large amount of Chemical substances, many types of acid-base salts, the main problem of domestic sewage is that there are many sundries, and there are very many insoluble fine substances in water, so the sedimentation and filtration device of domestic sewage is especially important

Abstract

The invention discloses a sedimentation device for domestic sewage. The sedimentation device comprises a base, a first-stage sedimentation chamber and a second-stage sedimentation chamber, wherein theupper end of the left side of the first-stage sedimentation chamber is provided with a water inlet, a motor is disposed at the intermediate position of the top end of the first-stage sedimentation chamber, a rotating shaft is arranged on the bottom end of the motor, a stirring frame is mounted on the rotating shaft, and an auxiliary box is disposed at the upper end of the right side of the first-stage sedimentation chamber. The top of the auxiliary box is provided with a material conveying pipe, a booster pump is arranged at the intermediate position of the material conveying pipe, and the terminal end of the material conveying pipe extends into the inner cavity of the first-stage sedimentation chamber, and is provided with a material homogenization pipe. The material homogenization pipeis fixed on the upper plane of the inner cavity of the first-stage sedimentation chamber; the beneficial effects are that: a flocculant is fully mixed with sewage to greatly accelerate the efficiencyof sewage sedimentation; and by multi-stage sedimentation treatment, impurities can be further eliminated by use of different densities of the impurities and the sewage, and sedimentation quality canbe improved.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a sedimentation device for domestic sewage. Background technique [0002] Sewage treatment: 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. [0003] The vast majority of township domestic sewage treatment processes follow the treatment process of urban sewage plants, but these treatment processes cannot effectively adapt to the characteristics of township domestic sewage; domestic sewage is different from industrial production sewage, with low harmful substances and does not contain a large amount of Chemical substances, many types of acid-base ...
