Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a water passing device for a sewage treatment pool. Background Art

[0002] The activated sludge method is a classic process that is widely used in the treatment of various types of sewage, such as municipal sewage and industrial wastewater. It often uses multiple sewage treatment tanks connected in series as the main reaction device. The tanks are separated by walls. The sewage flows from front to back in the tank and undergoes biochemical treatment to achieve the degradation and removal of pollutants.

[0003] At present, the existing water flow between sewage treatment pools is to open water holes on the partition walls of two adjacent sewage treatment pools (and the opening positions of adjacent partition walls follow the principle of "diagonal opening in the horizontal direction (looking down) and up and down opening in the vertical direction (elevation)", for example: if a hole is opened in the upper left position of the first partition wall, the next partition wall needs to be opened in the lower right position, so as to achieve sufficient material mixing and sufficient retention, and avoid the problem of "short flow" causing uneven mixing and short retention time, which will bring about unsatisfactory treatment effect). The water flow between the two adjacent treatment pools is achieved through the water holes. The method of directly passing water through the water holes is not necessary when the system is operating normally. No problem, but considering that the activated sludge method generally arranges facilities such as fillers and aeration pipes in each treatment pool, the above-mentioned facilities and materials in the pool will appear aging, damage and other problems after running for a period of time, and need to be supplemented and replaced and maintenance work is required. At this time, the water pool involved in the maintenance work and its adjacent pools must be emptied before entering the pool to work. This operation will double the workload of pool cleaning and increase the operation time. The greater impact is the greater impact on the operation of the system, which may reduce the treatment capacity of the sewage treatment system and even cause the loss of the system process section, forcing the front-end drainage to be restricted, production to be reduced or even stopped.

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.

[0020] As attached Figure 1-3 A sewage treatment pool water flow device shown includes: a No. 1 sewage treatment pool 1 and a No. 2 sewage treatment pool 2, a partition wall 3 is vertically installed between the No. 1 sewage treatment pool 1 and the No. 2 sewage treatment pool 2, one side of the partition wall 3 is located in the No. 2 sewage treatment pool 2 and a water flow pipe 4 is vertically provided, one end of the water flow pipe 4 passes through the partition wall 3 and horizontally extends into the No. 1 sewage treatment pool 1, a blocking mechanism 5 for blocking the water flow is provided at one end of the water flow pipe 4 located in the No. 1 sewage treatment pool 1, an exhaust mechanism 6 for exhausting the water flow in the water flow pipe 4 is provided at the top of the water flow pipe 4, and an anti-fouling mechanism 7 for blocking sediment is provided at one end of the water flow pipe 4 located in the No. 2 sewage treatment pool 2.

[0021] The blocking mechanism 5 includes an inlet valve 8 arranged in the No. 1 sewage treatment pool 1. The inlet valve 8 is located at one end of the water pipe 4. Flanges 9 are installed at both ends of the inlet valve 8. One of the flanges 9 is connected to one end of the water pipe 4 away from the end of the inlet valve 8.

[0022] The exhaust mechanism 6 includes an exhaust pipe 10 vertically opened at the top of the water pipe 4 , and an exhaust valve 11 is installed on the exhaust pipe 10 .

[0023] A plurality of arc-shaped fixing members 12 are arranged on one side of the water pipe 4 , and both ends of the arc-shaped fixing members 12 are connected to one side of the partition wall 3 by bolts.

[0024] The U-shaped outlet elbow pipe head 13 is installed at one end of the water pipe 4 located in the second sewage treatment tank 2, and the opening of the U-shaped outlet elbow pipe head 13 faces upward.

[0025] The specific implementation method is as follows: by setting a sealing mechanism 5, it is convenient to seal adjacent sewage treatment tanks, thereby improving the convenience and efficiency of equipment maintenance work in the treatment tank, greatly shortening the maintenance period, and improving work efficiency; and by setting an exhaust mechanism 6, it is convenient to exhaust the water pipe 4 to prevent gas from affecting the normal circulation of water.

[0026] As attached Figure 1 With attached Figure 3 A sewage treatment pool water passing device is shown, and the anti-fouling mechanism 7 includes an anti-fouling cover 14 arranged above a U-shaped water outlet elbow head 13, two connecting rods 15 are respectively installed at the two ends of the bottom of the anti-fouling cover 14, and two V-shaped clamping blocks 16 are respectively installed at the bottom ends of the two connecting rods 15, and both ends of the two V-shaped clamping blocks 16 are horizontally penetrated and connected with screws 17, and one end of the two screws 17 is threadedly connected with nuts 18.

[0027] The specific implementation method is as follows: by providing the anti-fouling mechanism 7, one end of the U-shaped water outlet elbow pipe head 13 is blocked to prevent sediment in the water from settling into the U-shaped water outlet elbow pipe head 13 and causing blockage.

[0028] Working principle of the utility model: when the sewage treatment system is operating normally, the water inlet valve 8 is opened, and the water in the No. 1 sewage treatment pool 1 overflows into the water pipe 4, flows downward along the water pipe 4 and enters the No. 2 sewage treatment pool 2 through the U-shaped water outlet elbow head 13, thereby realizing the transmission of water from the No. 1 sewage treatment pool 1 to the No. 2 sewage treatment pool 2. During this process, the exhaust valve 11 is opened, and the exhaust gas entrained in the water is discharged into the exhaust gas collection system or emptied through the exhaust pipe 10 to avoid the formation of air blockage affecting the circulation, wherein the function of the U-shaped water outlet elbow head 13 is to prevent the aeration in the No. 2 sewage treatment pool 2 from entering the water pipe 4. The gas generated by the aeration system flows upward. If it enters the pipe, it will flow upward along the water pipe 4 in the opposite direction to the water, which will cause air blockage to the water flow transmission in the water pipe 4 and affect the transmission efficiency. The U-shaped water outlet elbow head 13 can be set through the anti-fouling cover 14. The upper end is blocked to prevent the sediment in the water of the No. 2 sewage treatment pool 2 from settling into the U-shaped outlet elbow pipe head 13 to cause blockage and affect the normal circulation of the water flow. When installing the anti-fouling cover 14, it is only necessary to place the two V-shaped clamping blocks 16 on both sides of one end of the U-shaped outlet elbow pipe head 13, and then turn the nut 18 to clamp the anti-fouling cover 14 on one end of the U-shaped outlet elbow pipe head 13; when the equipment in the No. 1 sewage treatment pool 1 needs to be overhauled, it is only necessary to empty the No. 1 sewage treatment pool 1, close the water inlet valve 8, and install a blind plate at the flange 9 on the side of the water inlet valve 8 away from the water pipe 4, so as to isolate the liquid in the No. 2 sewage treatment pool 2 from reflux. At the same time, if there is a water pool in front of the No. 1 sewage treatment pool 1, the same operation is also performed to prevent the wastewater from the previous water pool from overflowing into the No. 1 sewage treatment pool 1. After the overhaul is completed, the blind plate is removed and the water inlet valve 8 is opened to restore to normal use.
