Problems solved by technology

[0008] (4) There are many solid impurities in the sewage. The sewage produced by the slaughtering and meat processing industry contains a large amount of solid impurities such as animal residues and hair, which increases the technical difficulty of pretreatment
Generally speaking, the sewage generated by the slaughtering and meat processing industry has high concentration of organic matter and rich nutrients, and it is directly discharged without treatment, which will easily affect the quality of surface water.
[0009] Increase its organic pollution and ammonia nitrogen load, and at the same time, the animal residues contained in it will breed a large number of mosquitoes and bacteria, endangering ecological health and safety

Embodiment 1

[0043] The present embodiment is based on the aquaculture sewage treatment system of EGSB anaerobic reactor, comprising: grid tank, fine particle screening device, pH adjustment tank, oil separation adjustment tank, water volume adjustment tank, EGSB anaerobic reactor and tower connected in series type biological filter, oxidation pond, subsurface constructed wetland;

[0044]The EGSB anaerobic reactor includes a water distribution device, a reaction area, a three-phase separator, and a water collection area arranged sequentially from bottom to top, and also includes a reaction area division device, which includes an adjustable riser, and the The perforated pipe vertically connected with the lifting pipe, the reaction zone is divided into the first sludge zone and the second sludge zone above the perforated pipe with the position of the perforated tube as the boundary, and the lifting tube is driven to lift in the reaction zone. , lowering lifting drive device, the lifting pip...

Embodiment ２

[0051] This embodiment is based on the aquaculture sewage treatment system of the EGSB anaerobic reactor. On the basis of Example 1, a rotating return water pipe device is also provided in the reaction zone, and the rotating return water pipe device includes a central water inlet pipe, which is in line with the described For several branch pipes connected by the central water pipe, the mud inlet end of each main pipe is connected to the central mud inlet pipe, and the mud outlet end is connected to an arc pipe. The angle formed by the intersection of each adjacent two main pipes is equal. Each arc The two mud outlet ends of the shaped pipe are respectively connected to a pipe, and a reinforcement pipe is connected between the branch pipe and the main pipe;

[0052] Wherein, the branch pipes, main pipes, and reinforcement pipes are all perforated pipes, and the central water inlet pipe is connected to the circulation pump.

[0053] Further, the rotary return pipe device is comp...

Embodiment ３

[0056] This embodiment is based on the aquaculture sewage treatment system of the EGSB anaerobic reactor. On the basis of Example 1, the water distribution device includes a number of straight water pipes evenly distributed at the bottom of the EGSB anaerobic reactor. There are valves at both ends, and the sewage to be treated enters the reactor through one end of the water distributor.

[0057] The water distributor is composed of several independent perforated water distribution pipes, which are evenly distributed in the EGS reactor, and each end is controlled by two valves outside the reactor, one end controls water intake, and the other end can be vented. When one of the perforated pipes is blocked and the other valves are closed, the perforated pipe can be opened by pressure. If the blockage is serious, the water inlet control valve can be closed and the vent valve can be opened to unclog it. This will not affect the normal operation of the entire EGSB system, because in ...

Abstract

The invention discloses a culture sewage processing system based on EGSB anaerobic reactor. The processing system comprises a screen tank, a fine grain screening device, a PH adjusting tank, an oil insulation adjusting tank, a water volume adjusting tank, an EGSB anaerobic reactor, a tower-type biological filter, an oxidation pond and a subsurface flow constructed wetland which are in series connection in order. The EGSB anaerobic reactor comprises a water distributing device, a reaction region, a three-phase separator and a water collection region which are arranged from bottom to top in order, and also comprises a reaction region partition device. The reaction region partition device comprises an adjustable lifter pipe and a perforated pipe communicated with the lifter pipe vertically. The reaction is divided into a first sludge region above the perforated pipe and a second sludge region with the position of the perforated pipe as a boundary. The reaction region partition device also comprises a lifter driving device driving the lifter pipe to go up and down in the reaction region. The lifter pipe is connected with a sewage backflow circulating pipe. A circulating pump is arranged on the sewage backflow circulating pipe. Scale marks indicating the going-up-and-down distance of the adjustable lifter pipe are arranged on the adjustable lifter tube.

Description

technical field [0001] The invention relates to an aquaculture sewage treatment system based on an EGSB anaerobic reactor. Background technique [0002] The traditional EGSB anaerobic reactor has only one reaction zone, and both the acid production stage and the methane production stage of the anaerobic reaction are carried out in this reaction zone. Because acid-producing bacteria have a certain inhibitory effect on methanogenic bacteria, the two can only coexist harmoniously, and cannot achieve the best living conditions for the two to exert the maximum treatment effect. Therefore, on the basis of the traditional EGSB, the present invention divides the reaction zone into two, and controls the ratio of the two reaction zones through an adjustable riser to adjust the ratio of the acid-producing phase to the methanogenic phase to achieve the best treatment effect. [0003] With the continuous growth of my country's per capita meat consumption level, the breeding and slaughte...
