Problems solved by technology

The current sedimentation tanks generally use the bottom to collect sludge and discharge it through the sludge discharge pipe installed at the bottom of the sedimentation tank. During the actual sludge discharge process, it is difficult to separate the sludge from water, and the sludge tends to accumulate at the sludge discharge outlet, but it is difficult to discharge the sludge discharge outlet in time. , resulting in unsatisfactory mud discharge effect, and it is difficult to discharge more comprehensively

Embodiment 1

[0030] Sewage treatment plants for urban watercourses, such as Figure 1-Figure 8 As shown, it includes a sedimentation tank 1 provided with a sludge discharge pipe 101. The upper part of the sedimentation tank 1 is provided with a water inlet pipe 102. The sedimentation tank 1 is provided with a sludge discharge mechanism 3 connected to the sludge discharge pipe 101. The sludge discharge mechanism 3 includes a A horizontally arranged mud storage pipe 301 and two downwardly inclined mud guide plates 302 are arranged symmetrically, and together with the front and rear side walls of the sedimentation tank 1, a conical mud storage chamber is formed. The mud storage pipe 301 One end is fixed on the inner side wall of the sedimentation tank 1, and the other end is connected to the mud discharge pipe 101. The upper side wall of the mud storage pipe 301 is provided with a mud inlet 303 extending along the length direction of the mud storage pipe 301 and opening upward. The lower ends...

Abstract

The invention relates to the field of sewage treatment, and discloses a sewage treatment device for urban rivers, which includes a sedimentation tank provided with a mud discharge pipe, and a mud discharge mechanism is arranged in the sedimentation tank, and the mud discharge mechanism includes a horizontally arranged mud storage pipe and two mud guide plates, the upper side wall of the mud storage pipe is provided with a mud inlet extending along the length direction of the mud storage pipe and opening upward, and the lower ends of the two mud guide plates are respectively fixed on both sides of the mud inlet, The side wall of the mud storage pipe is plugged with a mud guard pipe that is coaxial with the mud storage pipe and can rotate. The side wall of the mud guard pipe is provided with a mud passage that can cooperate with the mud inlet; the mud discharge mechanism also includes a set The mud scraper is located in the mud storage pipe and can move along the length direction of the mud storage pipe. The mud scraper is provided with a pull rod that can extend out of the mud discharge pipe. The present invention can discharge the sludge in the lower part of the sedimentation tank more comprehensively by designing the lower part of the sedimentation tank into a sludge sedimentation and sludge discharge structure with a special structure, and achieves a relatively 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 process is a variety of economical, reasonable, scientific and effective process methods for urban domestic sewage and industrial wastewater. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical, catering and other fields. The urban sewage treatment process should be determined according to the treatment scale, water quality characteristics, environmental functions of the receiving water body, and local actual conditions and requirements, after comprehensive technical and economic comparison. [0003] The general sewage treatment process includes steps such as water intake, aeration, sedimentation, and drainage. The sedimentation step is generally carried out in a sedimentation tank, which mainly realizes the ...
