I-shaped circulation self-mixing water distribution device and water distribution reactor

Abstract

The invention provides an I-shaped circulation self-mixing water distribution device and a water distribution reactor. The water distribution device includes a water inlet pipe, multistage water distribution pipes and a plurality of water distribution heads, wherein one end of the first-stage water distribution pipe vertically communicates with the water inlet pipe, and the tail ends of the last-stage water distribution pipe are connected with the water distribution heads; and one end of the intermediate water distribution pipe vertically communicates with one end of the upper-stage water distribution pipe, the other end of the intermediate water distribution pipe vertically communicates with one end of a lower-stage water distribution pipe, and the pipeline length between each water distribution head and the water inlet pipe is the same. Since the pipeline length between each water distribution head and the water inlet pipe is the same in the water distribution device provided by theembodiment of the invention, and the water distribution pipes with different stages vertically communicate mutually, the change amount of the angle of a pipeline passing through is also the same, energy loss of water flow of sewage drained from each water distribution head is the same, the flow velocity of the sewage drained from each water distribution head is the same, thus the sewage can evenlyenter the water distribution reactor, and then the efficiency of a hydrolysis reaction is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an I-shaped circulating self-mixing water distribution device and a water distribution reactor. Background technique [0002] The method of hydrolysis treatment of sewage is a method between aerobic and anaerobic sewage treatment methods, and the combination with other processes can reduce treatment costs and improve treatment efficiency. Hydrolysis refers to the biochemical reaction carried out outside the cell before the organic matter enters the microbial cell, that is, under the action of a large number of hydrolytic bacteria and acidifying bacteria, the insoluble organic matter is hydrolyzed into soluble organic matter, and the macromolecular substance that is difficult to biodegrade is converted into easily biodegradable The process of small molecular substances can improve the biodegradability of wastewater and lay a good foundation for subsequent treatment.

Problems solved by technology

[0005] In the current water distribution device, the length of the pipe that the sewage flows from the water inlet to each water distribution hole is different, and the speed of the sewage flowing out from the water distribution hole is different, resulting in uneven distribution of water by the water distribution device, which in turn affects the hydrolysis reaction. efficiency
