Problems solved by technology

The above-mentioned spiral biological nests are all single-helical, and compared with the double-helix biological belt of the present invention, the specific surface area is small, and the microorganisms adsorbed are less; and the current biological nests are placed in a fixed position, which is not conducive to the adsorption of flora. Gas production rate and water treatment efficiency are low

Embodiment Construction

[0007] Technical scheme of the present invention is as follows:

[0008] An anaerobic reactor comprises a water inlet pipe, a water / air dispersing device, a support, a biological belt, an air inlet pipe, a sludge discharge port and an air outlet. The support is a spider web structure composed of radial tubes and concentric tubes distributed radially around the center of the circle. The support is located in the upper part of the reactor. The biological belt is a double-helix biological belt. One end of the biological belt is fixed on the support, and the other end is freely floating in the water body; the water / gas dispersion device is arranged at the bottom of the reactor, and one end is connected to the water inlet pipe, and the other end is connected to the air inlet pipe.

[0009] Preferably, according to the present invention, a triangular support body is fixed on the inner wall of the reactor, and an annular backing plate is placed on the triangular support body, and the...

Abstract

The invention discloses an anaerobic reactor which mainly comprises a water inlet pipe, an air inlet pipe, a water / air dispersion device, a bracket and a double-helix biozone. In the anaerobic reactor provided by the invention, a double-helix biozone type anaerobic filter is used for providing carriers for the fixation and growth of bacteria; at the same time, air backflow and water agitation areutilized, so that the bacteria are distributed on a whole fermentation tank to the maximum, the anaerobic fermentation process is accelerated and the tank volume gas output and the water treatment efficiency are improved; and the size can be flexibly selected as required, so that the construction cost is saved. The reactor also can be used for extracting methane energy while treating sewage, so that the application prospect is wide.

Description

technical field [0001] The invention relates to a device for treating organic waste water by using double-helix biological belt technology, simultaneously producing biogas and extracting energy, and belongs to the technical field of organic waste water treatment. Background technique [0002] In recent years, with the vigorous development of my country's aquaculture industry, the degree of intensification of the aquaculture industry has continued to increase. Since most aquaculture farms are not equipped with farm manure resource utilization facilities, a large amount of solid waste and organic wastewater generated by aquaculture farms has become an issue for some One of the main sources of pollution in the region, especially in the suburbs of large and medium-sized cities, the problem of feces and sewage treatment in farms is becoming more and more serious in front of us. Pollution of water quality: Some harmful substances in feces, such as protein and fatty acid corruption ...
