The invention discloses a surrounding-type multilayer sewage treatment device which comprises a sewage discharge bin and a surrounding-type sewage treatment machine. A sewage treatment bin is arranged in the surrounding-type sewage treatment machine, a sewage adding bin is communicated to the top of the sewage treatment bin, a motor is arranged at the position of the middle of the top of the sewage treatment bin, the lower side of the motor is in driving connection with a rotation shaft through a reducer, a helical blade is welded to the rotation shaft, and an impurity storage bin is arranged at the bottom of the sewage treatment bin. A helical surrounding-type water feeding mode is adopted, sewage is sprayed to outer walls of the sewage treatment bin due to centrifugal force during water feeding, solid particles in the sewage are filtered by the aid of a first filter screen and a second filter screen, solids in the sewage can be rapidly separated, and subsequent sewage treatment is facilitated.
Description
technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a surrounding multi-layer sewage treatment device. Background technique [0002] Hospital sewage treatment usually includes primary treatment and secondary treatment. Generally speaking, if the treated effluent is discharged into the municipal sewer, usually only primary treatment is performed; if the treated effluent is directly discharged into the river, primary treatment and secondary treatment are required. Secondary treatment; For areas with strict discharge standards, in order to prevent eutrophication of water bodies, third-level treatment for phosphorus and nitrogen removal is required, and special hospital sewage such as acidic wastewater, phase washing wastewater, and radioactive wastewater should be strictly collected and processing. In some areas, in order to alleviate the contradiction of water supply shortage, advanced treatment and recycling of ...
