Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency anaerobic water distribution device. Background Art

[0002] Anaerobic biological treatment of sewage is a common technology with good environmental and economic benefits. The water distribution system of anaerobic treatment is the key to the anaerobic reaction tank. The anaerobic water distributor is used to distribute water to the anaerobic tank and to stir the water in the water distribution process to mix the mud and water. At present, there are several common water distribution forms of anaerobic water distributors: one-tube multi-hole water distribution method, branched one-tube multi-hole water distribution method, one-tube to one-point water distributor, and pulse water distributor.

[0003] However, the above water distribution methods all have many problems: 1. The water distribution device is prone to blockage during operation; 2. The water distribution is uneven, and it cannot ensure that the water distribution volume of each part of the anaerobic tank is the same; 3. It is easy to produce dead corners and mud accumulation in the anaerobic tank, affecting the treatment efficiency. No solution has been proposed for the relevant technical problems.

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] Example 1

[0015] See also Figure 1-2 The utility model proposes a technical solution of a high-efficiency anaerobic water distribution device: a high-efficiency anaerobic water distribution device, comprising an anaerobic reactor 1, water distribution bags 2 are arranged on both sides of the anaerobic reactor 1, a pressure gauge 3 is arranged between the anaerobic reactor 1 and the water distribution bag 2, a control valve 4 is arranged between the pressure gauge 3 and the anaerobic reactor 1, a water inlet pipe 5 is arranged on the top of the water distribution bag 2, an exhaust valve 6 is arranged on one side of the water distribution bag 2, a sewage valve 7 is arranged on the other side of the water distribution bag 2, and a plurality of water distribution branches 8 are arranged inside the anaerobic reactor 1.

[0016] See also Figure 1 As shown, further, one end of the water distribution branch pipe 8 is connected to the water distribution bag 2 , and the pressure gauge 3 and the control valve 4 are both installed on the water distribution branch pipe 8 .

[0017] See also Figure 1 As shown, further, twelve water distribution branch pipes 8 are provided.

[0018] The working principle of this utility model:

[0019] The sewage enters the water distribution bag 2 along the water inlet pipe 5, and after a water distribution in the water distribution bag 2, it flows into the anaerobic reactor 1 along the water distribution branch pipe 8 to achieve uniform water distribution;

[0020] The sewage flows into the water distribution bag 2 along the water inlet pipe 5, achieving uniform water distribution at one time, and the sewage is evenly distributed around it. At the same time, a sewage discharge valve 7 and an exhaust valve 6 are installed on the water distribution bag 2. When the sewage contains a lot of impurities and the water distribution bag is blocked, the sewage discharge valve 7 can be opened to clean out the impurities. When there is a lot of gas in the water distribution bag 2 that affects the subsequent water distribution process, the exhaust valve 6 can be opened to discharge the excess gas.

[0021] The sewage is evenly distributed in the anaerobic reactor 1 through the outlet holes on the water distribution branch pipe 8, achieving secondary uniform water distribution. The end of the water distribution branch pipe 8 is vertically downward, and the pressurized sewage is sprayed out from the outlet hole at a high speed, so that the muddy water at the bottom of the anaerobic reactor 1 is fully in contact, increasing the contact area between the wastewater and the sludge, improving the reaction efficiency, and balancing the inlet water concentration. The required size, quantity and position of the water distribution branch pipe 8 need to be calculated according to the amount of water before design and layout;

[0022] A pressure gauge 3 and a two-stage control valve 4 are sequentially installed at the front end of the water distribution branch pipe 8 before entering the anaerobic reactor 1. When the water distribution branch pipe 8 is blocked, the pressure gauge 3 installed on the pipe reads zero. The remaining one or more branches are closed according to the actual situation, and the pressure of the blocked pipe increases instantly. The strong impact force flushes the blocked part, which solves the blockage problem of the water distribution device simply, quickly and effectively. The two-stage control valve 4 is installed. If the first-stage valve fails during the later operation, the second-stage valve can ensure the normal water distribution of the remaining water distribution branches.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.
