Abstract

The invention relates to the field of sewage treatment, and discloses a sewage treatment device for an urban river channel. The device comprises a precipitation tank provided with a mud discharge pipe, wherein a mud discharge mechanism is arranged in the precipitation tank, and comprises a transversely arranged mud storage pipeand two mud guide plates, a mud inlet extending in the length directionof the mud storage pipe and provided with an upward opening is formed in the upper side wall of the mud storage pipe, the lower ends of the two mud guide plates are respectively fixed at the two sides of the mud inlet, a mud blocking pipe arranged coaxial with the mud storage pipe and capable of rotating is inserted into the side wall of the mud storage pipe, a mud passing opening capable of being matched with the mud inlet is formed in the side wall of the mud blocking pipe, the mud discharge mechanism further comprises a mud scraping plate arranged in the mud storage pipe and capable of moving in the length direction of the mud storage pipe, and a pull rod capable of extending out of the mud discharge pipe is arranged on the mud scraping plate. According to the invention, the lower portion of the precipitation tank is designed into the sludge precipitation and sludge discharge structure with the special structure, so that the sludge at the lower portion of the precipitation tank canbe comprehensively discharged so as to achieve the ideal sludge discharge effect.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device. Background technique [0002] Sewage treatment technology is a variety of economical, reasonable, scientific and effective methods for urban domestic sewage and industrial wastewater. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields. The urban sewage treatment process should be optimized and determined after a comprehensive technical and economic comparison based on the treatment scale, water quality characteristics, environmental functions of the receiving water body, and local actual conditions and requirements. [0003] The general sewage treatment process includes steps such as water intake, aeration, sedimentation, and drainage. The sedimentation step is generally carried out by a sedimentation tank, which main...
