Abstract

The invention discloses a high-efficiency multistage biological infiltration sewage treatment device and method. The device comprises a water inlet pipe, a filter tank, a flocculation tank and a sedimentation tank, the filter tank, the flocculation tank and the sedimentation tank are connected by pipes, a water outlet end of the water inlet pipe is positioned on one side close to the top of the filter tank, a grid, a first filter layer, a second filter layer and a third filter layer are sequentially arranged on the inner wall of the filter tank, the top of the flocculation tank is fixedly connected with a plurality of first motors through brackets, shaft extension ends of the first motors are fixedly connected with stirring shafts, a drainage pipe is arranged on the outer wall, close to the bottom, of the sedimentation tank in a penetrating manner, and the bottom of the sedimentation tank is conical. By arranging the filter layer, the first filter layer, the second filter layer and thelike, impurities in sewage can be effectively filtered by utilizing multi-stage biological infiltration, so that the working load of a subsequent treatment device is greatly reduced, the sewage treatment effect is good, the treatment cost of water per unit volume is greatly reduced, and the practicability is high.

Description

technical field [0001] The invention relates to a device and a treatment method, in particular to a high-efficiency multi-stage biofiltration sewage treatment device and a treatment method. Background technique [0002] The process of purifying sewage to meet the water quality requirements for discharge into a certain water body 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. According to the classification of sewage sources, sewage treatment is generally Divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex mixture of various forms of inorganic and orga...
