Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a coordinated digestion anaerobic biological treatment device. Background Art

[0002] Modern industrial production processes generate a large amount of industrial wastewater. Improper treatment of industrial wastewater will cause serious damage to human health and the ecological environment.

[0003] At present, the commonly used treatment processes for industrial wastewater with high COD, calcium and magnesium ion, and sulfate content are hydrolysis acidification and anaerobic granular sludge reactors. The hydrolysis acidification tank adopts mechanical stirring, and the equipment has high energy consumption and high failure rate, and is prone to sludge dead corners. Or it adopts conventional point-to-point water distributors, which have low static pressure, slow flow rate, and small pipe inner diameter, which are easy to cause blockage and ultimately lead to poor operating results. When treating high-concentration wastewater, anaerobic granular sludge reactors are prone to sludge calcification or acidification. They are sensitive to the biological toxicity of wastewater, and sludge needs to be replenished in time after calcification or loss. The cost of purchasing granular sludge is high, and the system treatment effect is unstable. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model discloses a collaborative digestion anaerobic biological treatment device, including a tank body 1, the inner cavity of the tank body 1 is equipped with a central tube 2, the bottom end of one side of the central tube 2 is connected to a water inlet pipe 3, the top of the tank body 1 is provided with a siphon pulse device, the central tube 2 cooperates with the siphon pulse device, the outer wall of the central tube 2 is provided with at least one pulse water distribution pipe 7, the siphon pulse device includes a tank body 8, a down pipe 5, a siphon cover 9 and a U-shaped tube 10, the tank body 8 is equipped with a down pipe 5 with one end extending into the inner cavity of the tank body 8 and the other end extending into the inner cavity of the central tube 2, the inner cavity of the tank body 8 is liftable and provided with a siphon cover 9 cooperating with the down pipe 5, and the siphon cover 9 is equipped with a U-shaped tube 10.

[0018] A vent pipe 11 is installed on one side of the bottom of the tank body 8 .

[0019] Specifically, a water outlet weir 15 is provided on one side of the pool body 1 .

[0020] Specifically, a support leg 14 is fixedly connected to the bottom of the tank body 8 , and the tank body 8 is connected to the pool body 1 via the support leg 14 .

[0021] Specifically, a connecting pipe 12 for water inlet is provided on one side of the tank body 8, a liquid storage tank 4 is formed on one side of the inner cavity of the pool body 1, and the liquid storage tank 4 is connected to the inner cavity of the pool body 1 through a connecting pipe 16 with a valve, and a circulating pump 6 is installed on the top of the pool body 1 to extract the supernatant in the liquid storage tank 4 and input it into the connecting pipe 12.

[0022] In this embodiment, the supernatant after the anaerobic reaction in the upper part of the tank body 1 can partially enter the liquid storage tank 4 and be transported to the tank body 8 through the circulation pump 6 .

[0023] Specifically, the top of the tank body 8 is rotatably connected with a screw rod 13 , and the bottom end of the screw rod 13 is connected to the siphon cover 9 .

[0024] In the present embodiment, after the supernatant on the pool body 1 is transported to the tank body 8, as the water level continues to rise, the supernatant flows through the siphon hood 9 to the top of the downcomer 5, and then the supernatant flows from the downcomer 5 into the central tube 2. The fast-flowing water flow continuously takes away the air at the upper end of the siphon hood 9, so that a certain vacuum degree is formed in the siphon hood 9. When the water reaches the highest water level of the siphon, a pulse can occur. Under the action of the atmospheric pressure inside and outside the siphon hood 9, the water flow in the tank body 8 will pass through the U-shaped tube 10 and flow into the downcomer 5. When a pulse occurs, due to the fast water flow speed, the water distribution can be completed in a short time, forcing the supernatant to enter the central tube 2 at high speed, and then the central tube 2 is distributed to the pulse water distribution pipe 7 for water distribution.

[0025] In summary, the collaborative digestion anaerobic biological treatment device eliminates the mechanical stirring method and instead generates pulses through the siphon effect to disturb the sludge at the bottom of the tank body 1, avoiding the formation of sludge dead corners, and saving the energy consumption generated by large mechanical stirring equipment during operation, reducing the probability of failure and saving operating costs.
