Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment field, concretely speaking, a kind of annular uniform fixed-point water distribution device. BACKGROUND

[0002] High-concentration organic wastewater treatment system usually adopts anaerobic reaction tank+oxygen reaction tank treatment process, wherein anaerobic reaction tank is more strict to water distribution and sludge-water mixing, and whether uniform water distribution is one of the key factors to determine the treatment efficiency of anaerobic reaction tank. In the prior art, water distribution pipe is mostly arranged at the bottom of the tank, and perforated pipe type water distribution form is adopted, that is, circular openings are uniformly opened on the water distribution pipe to form water distribution holes. After a period of operation, the water distribution holes may be blocked. Since the circular openings are uniformly opened on the whole pipe, it is difficult to open the blocked water distribution holes by increasing the flushing water, which causes the problem that the treated wastewater cannot be in contact with the microbial sludge in the reaction tank in some areas, and reduces the efficiency of the reaction tank. For example, CN218262145U discloses an anaerobic tank and a sewage treatment system, which is provided with a water distribution pipe group in a meandering structure at the bottom of the tank body. In addition, the prior art also uses water distributor to realize pulse water distribution, for example, CN210915508U discloses a pulse water distribution type UASB anaerobic reactor, which comprises an inlet pipe, an outlet pipe and a pulse water distributor. The inlet pipe is vertically arranged at the center of the tank body. The bottom outlet of the pulse water distributor is connected to the top opening of the inlet pipe. The outlet pipe is connected to the bottom of the inlet pipe and discharges water at the bottom of the tank body. However, this pulse water distribution method needs to strictly control the water inflow and pulse cycle, which is difficult to operate and manage. The water distribution amount is small in the two periods before and after the cycle, and the sludge and water in the reaction tank cannot be fully mixed. CONTENT OF THE UTILITY MODEL

[0024] As Figure 1 And 6 Indicated, the utility model works, water first flows into the water inlet inner ring 101, then overflows into the water inlet outer ring 102 again, and evenly flows into the water inlet ring cavity 303 of water distribution ring 3 through each water distribution pipe 2, then overflows the water weir plate 301 and flows into the water outlet ring cavity 304 of water distribution ring 3, and finally flows directly to the bottom of anaerobic tank body through each water distribution end pipe 302 and water distribution output pipe 4.

[0025] The utility model discloses a design first can realize large area even water distribution, especially suitable for the anaerobic equipment of large volume big water quantity, wherein the water inlet is overflowed into the water inlet outer ring 102 from the water inlet inner ring 101, then flows into each distribution pipe 2, which can realize the purpose of quick and even water distribution, and the water inlet is overflowed into the water outlet ring cavity 304 from the water inlet ring cavity 303 of the water distribution ring 3, which can realize the purpose of quick and even water distribution, in addition, the water inlet outer ring 102 and water distribution ring 3 all adopt annular channel structure, and the diameter of distribution pipe 2 is also relatively thick to meet the requirement of quick water distribution, which greatly reduces the possibility of pipeline blockage by impurities in water, and each water distribution output pipe 4 is arranged along the height direction of the anaerobic tank body, so that even if there are impurities in water, the impurities can flow into the anaerobic tank body under the action of gravity and water flow, and blockage does not occur, therefore, the utility model realizes the efficient anti-blocking function of water distribution pipeline in addition to realizing large area even water distribution by the water inlet ring group 1 and water distribution ring 3 in the water inlet unit 1.

[0026] As Figures 1-2 The upper end opening of the water inlet inner ring 101 is lower than the upper end opening of the water inlet outer ring 102.

[0027] As Figure 1 And Figure 6 In the embodiment, the upper end of the anaerobic tank body is provided with a water inlet support frame 5, and the water inlet ring group 1 and the water distribution ring 3 are both installed on the water inlet support frame 5.

The water flow output from the water distribution output pipe 4 is bent upward under the reflection of the reflective cone plate 301 at the bottom of the anaerobic tank, until it enters the three-phase separation unit to achieve the separation of gas, water and mud into three phases.
