Jet anaerobic reactor

Abstract

The invention discloses a jet anaerobic reactor. The reactor comprises an inner box body and an outer box body, wherein the inner box body is sleeved with the outer box body, the inner box body is a central precipitation separation zone, the area between the inner box body and the outer box body is an anaerobic reaction zone, the inner wall of the outer box body is provided with a jet device and an ancillary submersible pump, a biological membrane is hung in the central precipitation separation zone, a water inlet pipe enters the area between the inner box body and the outer box body from theouter side of the outer box body close to the bottom, the water inlet pipe is bent upwards, extends to the area below the upper end surface of the inner box body, and is fixed on the outer wall of theinner box body;a water outlet groove is arranged in the inner box body close to the upper end, and is communicated with the water outlet pipe extending to the outer box body close to the outer part of the bottom surface;the side surface of the outer box body close to the bottom is provided with a mud blow-down pipe communicated with the inner part of the outer box body;the bottom of the inner boxbody is provided with a rectifying plate, the lower part of the rectifying plate is supported on a conical reflecting plate, and the bottom part of the conical reflecting plate is fixed on the innerbottom surface of the outer box body.The reactor has the advantages of simple structure, low energy consumption, low noise, small occupied area and convenient operation management.

Description

technical field [0001] The invention relates to a sewage treatment technology, in particular to a jet anaerobic reactor for the treatment of high-concentration nitrogen-containing aquaculture wastewater. Background technique [0002] At present, there are many kinds of domestic and foreign sewage anaerobic treatment equipment, such as digester, UASB, EGSB, anaerobic biofilm reactor and so on. Their mixing and mixing equipment mainly include biogas stirring, mechanical stirring, steam stirring and so on. [0003] Chinese patent CN 208414133 U discloses a co-flocculation air flotation anaerobic bioreactor. The co-flocculation air flotation anaerobic bioreactor mainly includes a biological reaction area, a dosing mixing area and a flocculation air flotation area. The medicine tank, flow control valve and ejector, the flocculation air flotation area are equipped with a direct-flow vortex reaction tank, a downflow chamber, a slag scraper, a slag collection tank, a downflow pipe...

AI Technical Summary

Problems solved by technology

The main disadvantage and deficiency of this patent is that it is difficult to guarantee the treatment effect when the amount of biogas produced is unstable or insufficient

The main disadvantages and deficiencies of this patent are: complex equipment, difficult management, high power consumption, and inability to stabilize the processing effect

[0006] The above-mentioned equipment has problems such as complex structure, high energy consumption, large floor area, complicated operation and management, and difficult automation.
