Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a novel upflow anaerobic reaction device. Background Art

[0002] Anaerobic biological treatment refers to a sewage treatment method that utilizes the metabolic process of anaerobic microorganisms (including facultative anaerobic microorganisms) to convert organic pollutants in sewage into inorganic matter and a small amount of cellular substances under anaerobic conditions. It is also called anaerobic digestion.

[0003] Anaerobic microorganisms are usually in activated sludge. Therefore, when sewage is anaerobically treated, the activated sludge and sewage are brought into contact, and the anaerobic microorganisms transform the organic pollutants in the sewage.

[0004] In order to ensure better contact between sewage and activated sludge, after the sludge is added to the reaction area, the sewage is flushed into the reaction area from the bottom to ensure sufficient contact between the sewage and the activated sludge, thereby promoting the anaerobic reaction of the sewage. However, as the sewage is flushed, the activated sludge is easily lost along with the flow of sewage, so it is necessary to frequently add activated sludge to the reaction area, which is a cumbersome operation. Utility Model Content

[0005] The utility model aims to provide a novel upflow anaerobic reaction device to solve the problem in the above background technology that activated sludge is easily lost along with the flow of sewage as it is flushed, so that activated sludge needs to be frequently added to the reaction area, which makes the operation more complicated.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a novel upflow anaerobic reaction device, comprising:

[0007] A reaction chamber, wherein the reaction chamber is hollow and has an upper opening;

[0008] A sewage inlet pipe, one end of which extends to the lower side of the reaction chamber, an inlet matching the sewage inlet pipe is provided on the lower surface of the reaction chamber, and a suction pump is installed on the sewage inlet pipe;

[0009] A sewage outlet, the sewage outlet being connected to the upper side of the side wall of the reaction chamber;

[0010] The filtering inclined tube comprises a plurality of unit inclined tubes, the outer walls of the plurality of unit inclined tubes are fitted together, the filtering inclined tube is arranged on the upper inner side of the reaction chamber, and the upper end of the filtering inclined tube is lower than the sewage output port.

[0011] Preferably, a sealing cover is provided at the upper opening of the reaction chamber, and an edge of the sealing cover is sealed and connected to the upper opening of the reaction chamber.

[0012] Preferably, a slag outlet is provided at the bottom of the reaction chamber, and a bottom cover is provided at the bottom of the slag outlet.

[0016] Preferably, a support is provided on the lower surface of the water distribution pipe, and the bottom end of the support is connected to the inner lower side of the reaction chamber.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0033] Analysis of the above content: Anaerobic reaction usually does not supply air to the sewage, so that the oxygen content in the sewage is low, which can meet the anaerobic reaction. According to the use requirements, if the reaction chamber 1 does not need to contact the air at all, the upper opening of the reaction chamber 1 can be covered by the cover 2. If the reaction chamber 1 is open and can also meet the anaerobic reaction, the cover 2 does not need to cover the upper opening of the reaction chamber 1.
