Efficient sewage treatment tower

Abstract

The invention discloses an efficient sewage treatment tower. The sewage treatment tower comprises a tower body, a sewage inlet pipe, a manifold and an annular water tank; a clean water discharge port and a sludge discharge port are formed in a shell of a base, and a sludge storage hopper with the wide upper portion and the narrow lower portion is arranged in the shell of the base; an inner container with an opening in the lower end is installed in an outer shell, and at least one filtering channel is formed between the outside of the wall of the inner container and the wall of the outer shell; the manifold is installed at the top end of the inner container and connected with the sewage inlet pipe; the annular water tank is fixed to the outer side of the wall of the upper portion of the outer shell and connected with the filtering channels, a water outlet is formed in the annular water tank and connected with the clean water discharge port through a clean water discharge pipe, and the cubic number of water contained in the filtering channels is at least 100 times larger than the water output cubic number of the water outlet. The sewage treatment tower is capable of filtering sewage through self-filtration without arranging a filtering net or filtering element, and has the advantages of being high in sewage treatment efficiency, low in operation and maintenance cost, convenient to operate and small in occupied area.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a high-efficiency sewage treatment tower. Background technique [0002] In order to save water resources and reduce environmental pollution, whether it is industrial or domestic sewage, it must be treated by a special sewage treatment device before it can be discharged or used. At present, the commonly used sewage treatment devices almost all use filter screens or filter elements to coarsely filter the sediment or suspended solids in the water, then use multi-stage sedimentation tanks for sedimentation, and then use high-pressure mud pumps to pump the sedimentation to press filtration. Machine filter. The traditional sewage treatment device has the following defects in the process of use: [0003] 1. Sedimentation tanks require one-by-one crop rotation, long settling time, heavy workload, and low treatment efficiency. In the existing technology, in order to speed up the sedimentatio...

Problems solved by technology

[0003] 1. Sedimentation tanks require one-by-one crop rotation, long settling time, heavy workload, and low treatment efficiency. In the existing technology, in order to speed up the sedimentation speed of sewage, a large amount of water purifier is often added to the settling tank, although the settling time is reduced. , but due to the addition of water purifiers, the pH value of the sewage changes, which directly affects the recycling of wastewater; and the sedimentation tank covers
