Problems solved by technology

[0004] The purpose of the present invention is to provide an anaerobic sensor for sewage treatment in order to overcome the problems of the existing technology that the anaerobic reactor has a tall shape and is not conducive to heat preservation. Due to the mass transfer conditions inside the oxygen reactor, the shape of the anaerobic reactor can be designed relatively low to facilitate heat preservation while maintaining high treatment efficiency

Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] figure 1 A schematic structural view of an anaerobic reactor for sewage treatment according to an embodiment of the present invention is shown. Such as figure 1 As shown, the embodiment of the present invention provides an anaerobic reactor for sewage treatment. The anaerobic reactor includes a tank body 1, a sewage inlet pipe 2 arranged on one side of the tank body, and a sewage inlet pipe 2 arranged on the tank body 1. The aeration pipe network 3 at the bottom of the tank body and the biogas collection area 4 at the top of the tank body. The tank body 1 has anaerobic activated sludge for degrading organic pollutants in the sewage. The biogas collectio...

Abstract

The invention relates to the field of anaerobic reactors, and discloses an anaerobic reactor for sewage treatment. The anaerobic reactor comprises a tank (1), a sewage inlet pipe (2) arranged on one side of the tank (1), an aerating pipe network (3) arranged on the bottom of the tank (1), and a methane gathering area (4) located on the top of the tank (1), anaerobic activated sludge for degradingorganic pollutants in sewage is arranged in the tank (1), and the methane gathering area (4) is communicated with the aerating pipe network (2) through a methane return pipe (5). The anaerobic reactorutilizes methane return to enhance the mass transfer condition in the anaerobic reactor, consequently, the shape of the anaerobic reactor can be designed to be short in order to realize heat preservation, and moreover, high treatment efficiency can be kept as well.

Description

technical field [0001] The invention relates to the field of anaerobic reactors, in particular to anaerobic reactors for sewage treatment. Background technique [0002] There are many types of existing anaerobic reactors, the most famous of which are UASB, EGSB, and IC anaerobic reactors. The advantages of these anaerobic reactors are high processing efficiency, small footprint, and high impact resistance to large loads. . At present, the widely popular anaerobic reactors are tall and tall. The height of the anaerobic reactor is relatively low for UASB, 98% of which are 5.5-18m high, while the heights of EGSB and IC are usually 12-28m. This is because the power consumption for strengthening the internal mass transfer will be very low after the height increases, and the processing efficiency will be greatly improved. Therefore, the outstanding feature of the common anaerobic reactor is the tall shape and structure. [0003] In the northern part of my country, due to the l...
