A high-efficiency sewage treatment tower

Abstract

The invention discloses a high-efficiency sewage treatment tower, which includes a tower body and a sewage inlet pipe, and also includes a water separator and an annular water tank. The shell of the base is provided with a clean water discharge port and a sludge discharge port, and the There is a mud storage hopper with a wide top and a narrow bottom; an inner tank with an open lower end is installed in the outer shell, and at least one filter channel is provided between the outer wall of the inner tank and the outer wall of the outer shell; the water separator is installed in the inner tank. The top of the tank is connected to the sewage inlet pipe; the annular water tank is fixed on the outer side of the upper wall of the shell and connected to the filter channel. The annular water tank is provided with a water outlet, which is connected to the clean water discharge port through the clean water discharge pipe, and The cubic number of water output is at least 100 times smaller than the cubic number of water contained in the filter channel. The sewage treatment tower can realize self-filtration to filter sewage without setting filter screen and filter element, and has the characteristics of high sewage treatment efficiency, low operation and maintenance costs, convenient operation and small 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...

AI Technical Summary

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 a large area and the cost of sewage treatment is high;

[0004] 2. The supporting filter, filter element and filter press equipment are easy to wear and tear, and are easily blocked by sediment and suspended matter. They need to be cleaned, dredged or replaced regularly. The use of a single machine cannot be used continuously, which directly affects production and consumes water. Power consumption, high operation and maintenance costs, not conducive to energy saving and emission reduction
