Problems solved by technology

[0003] In the prior art, there are many methods for gas-solid-liquid separation. One is to use a physical method, that is, to put a stirrer in the device, but with stirring, the bacterial population will be destroyed, hindering its granulation, and making the gas-solid-liquid The natural separation of natural separation has certain limitations, and this method will destroy the bacteria and cause the loss of bacteria, thereby reducing the efficiency of the separation device; Heavy force is used to achieve gas-solid-liquid separation. In this method, the separation efficiency of bacteria and gas is low, and the loss of bacteria is serious.

Embodiment 1

[0023] Example 1: In Figure 1 to Figure 3 In the process, the raw water 1 is input from the lower part of the upflow sewage treatment device 2, and when it passes through the microbial layer 3, due to the acidification and decomposition of the raw water 1 in contact with the microorganisms, irregular bacterial cells wrapped in biogas are formed, under the action of the buoyancy of the gas Next, the irregular bacteria surrounded by biogas float up to the gas-solid-liquid separation device 4, in the gas-solid-liquid separation device, due to the effect of the obstacle device, the bacteria and the biogas are fully separated, and the separated bacteria go down Sink back to the microbial layer, while the methane is discharged, the purified treated water 5 is discharged through the treated water overflow port 6 at the top. In this embodiment, the gas-solid-liquid separation device 4 is installed in the upflow sewage At two-thirds of the height of the treatment device, a wedge-shape...

Embodiment 2

[0024] Example 2: see Figure 4 The gas-solid-liquid separation device 4 is internally provided with a sawtooth-shaped obstacle device, and the sawtooth direction forms an acute or obtuse angle with the flow direction of the raw water 1. The outer contour of the gas-solid-liquid separation device 4 is a cylinder with the same outer diameter on the upper end surface and the lower end surface, The inner diameter of the end surface is 80% of the inner diameter of the upflow sewage treatment device 2, the inlet diameter 41 of the gas-solid-liquid separation device 4 is the same as the outlet diameter 42, and the gas-solid-liquid separation device 4 is fixed on the upflow sewage treatment device 2 by screw connection For other structures of this embodiment, refer to the structure in Embodiment 1.

Embodiment 3

[0025] Embodiment 3: see Figure 5 The gas-solid-liquid separation device 4 is provided with a labyrinth obstacle device inside, and the obstacle device is a labyrinth structure composed of protrusions forming a certain angle with the horizontal or vertical direction, and the outer contour of the gas-solid-liquid separation device 4 is a trapezoid , the inner diameter of the lower end surface is the largest, and the inner diameter of the lower end surface is 85% of the inner diameter of the upflow sewage treatment device 2. The inlet diameter 41 and the outlet diameter 42 of the gas-solid-liquid separation device 4 are determined according to the shape of the obstacle device. Other structures of the present embodiment See Example 1.

Abstract

The invention relates to a gas-liquid-solid separation device and a gas-liquid-solid separation method. The gas-liquid-solid separation device is arranged in an upflow sewage treatment unit, obstacle devices are arranged in the gas-liquid-solid separation device, the obstacle devices and the water flow direction of the sewage in the sewage treatment unit form a certain angle, and the obstacle devices constitute a sewage channel. The gas-liquid-solid separation device and the gas-liquid-solid separation method have the advantages of high thallus and gas separation efficiency, little thallus loss, and high sewage treatment efficiency, and can continuously maintain the sewage treatment capacity.

Description

Technical field: [0001] The invention relates to a sewage treatment device, especially an upflow sewage treatment device. Background technique: [0002] When the sewage treatment adopts the upflow anaerobic method, the treated water (raw water) is input from the lower part of the anaerobic treatment device. When the raw water passes through the anaerobic microbial layer, the raw water contacts with the microorganisms and is acidified and decomposed to be purified. During this period, a part of the dirty material Generates biogas (methane gas, sulfide gas, carbon dioxide gas), attaches to the bacteria, and moves to the upper part of the anaerobic treatment device, and the bacteria that move to the upper part are separated from the biogas quickly to maintain and improve its processing capacity An indispensable part, if the biogas and bacteria are not separated quickly, the bacteria will be discharged out of the device along with the treated water, and the processing capacity o...
