Sewage treatment device and method

Abstract

The invention discloses a sewage treatment device and method. The sewage treatment device comprises a main body, wherein a precipitation tank and a filtering tank are formed in the top surface of themain body, a side plate is fixedly arranged at the edge of the outer ring of the tank opening of the precipitation tank, a floating object fishing assembly is fixedly arranged on the top surface of the side plate and comprises a vertical plate fixedly connected with the top surface of the side plate, a connecting rod is embedded into the back face of the upper end of the vertical plate, the outerside of the connecting rod is movably sleeved with a first gear, a motor box is further fixedly arranged on the top face of the side plate, a motor groove is formed in the motor box, and a motor is fixedly arranged in the motor groove. According to the invention, a collecting groove is formed in a floating object collecting cylinder, a floating object inlet communicating with the collecting grooveis formed in the top end of the floating object collecting cylinder, the outer side of the floating object collecting cylinder is movably connected with a cylindrical outer frame in a sleeving mode,and a plurality of salvage hook pieces which are annularly distributed at equal intervals are fixedly arranged on the outer side of the cylindrical outer frame, so that the device can be used for fishing floaters and collecting the fished floaters at the same time.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device and a treatment method. Background technique [0002] Sewage treatment is 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; [0003] Sewage treatment usually needs to wait for the sludge and fixed sediment in the water to settle in the sedimentation tank first, and then discharge it after being filtered through the filter tank to meet the discharge standard. However, in addition to sludge and solid sediment, sewage usually contains For some floating objects, if the floating objects are not salvaged, the floating o...

Problems solved by technology

[0003] Sewage treatment usually needs to wait for the sludge and fixed sediment in the water to settle in the sedimentation tank first, and then discharge it after being filtered through the filter tank to meet the discharge standard. However, in addition to sludge and solid sediment, sewage usually contains For some floating objects, if the floating objects are not salvaged, the floating objects may enter the filter tank, which will affect the filtering effect of the filter layer inside the filter tank, and it is difficult to clean up. In the prior art, most of the floating objects in the sedimentation tank are salvaged manually. Manual salvage is time-consuming, labor-intensive, and has low work efficiency, which increases unnecessary labor and time costs. Therefore, it is necessary to invent a sewage treatment device and treatment method to solve the above problems
