[0002] Traditional hydrolysis acidification water distribution systems have the following technical drawbacks:
[0003] 1. Uneven water distribution: Fixed water distribution pipes are prone to short-circuiting and dead zones, leading to localized acidification and failure of the sludge bed.
[0004] 2. Insufficient sludge bed disturbance: Continuous water flow makes it difficult to effectively agitate the sludge layer, affecting mass transfer efficiency.
[0005] 3. Prone to clogging: High SS wastewater (such as food processing wastewater) often causes blockage of the water distribution holes, requiring frequent manual cleaning.
[0006] 4. High energy consumption: When mechanical stirring is used, electricity consumption accounts for more than 30% of the total energy consumption of the system. Summary of the Invention

Detailed Implementation
[0027] This utility model embodiment provides a hydrolysis acidification pulse water distribution device, such as... Figure 1-4 As shown, the device includes a pulse generator body 101 and a water distribution system 1001. A hydrolysis acidification tank 108 is located below the pulse generator body 101. Support legs 104 are fixedly installed at the bottom of the pulse generator body 101 for support. The support legs 104 are arranged in a circular array. Four water distribution systems 1001 are located at the bottom of the hydrolysis acidification tank 108. A water baffle 120 is fixedly installed inside the pulse generator body 101. The water baffle 120 divides the inside of the pulse generator body 101 into an inlet area 111 and a receiving area 121. The inlet area 111 is located above the water baffle 120, and the receiving area 121 is located below the water baffle 120. A water outlet pipe 103 is connected to the bottom of the receiving area 121. The bottom of the water outlet pipe 103 extends downward to the bottom of the hydrolysis acidification tank 108 and is connected to a connecting pipe 107. The connecting pipe 107 is connected to the water distribution systems 1001 on each side.
[0028] Furthermore, an exhaust pipe 109 is provided on one side of the top of the water-blocking plate 120, and the bottom of the exhaust pipe 109 is connected to the water receiving area 121.
[0029] It should be further noted that the top opening of the exhaust pipe 109 is located above the water inlet area 111.
[0030] Furthermore, a pulse generating tube 110 is installed at the center of the baffle plate 120. The lower end of the pulse generating tube 110 extends through the baffle plate 120 into the water receiving area 121 and is provided with a water seal groove 123.
[0031] It should be further noted that the opening at the top of the pulse generating tube 110 is located inside and above the water inlet zone 111.
[0032] Furthermore, a circular cylindrical bell jar 112 is fixedly installed at the center of the top of the water inlet zone 111, and the bell jar 112 covers the outer end face of the pulse generating tube 110.
[0033] Furthermore, a pulse disruption tube 114 is connected to one side of the top of the outer end face of the bell jar 112, and the outlet of the other end of the pulse disruption tube 114 is located inside and below the water inlet zone 111.
[0034] Furthermore, a water inlet pipe 102 is tangentially connected to one side of the outer end face of the pulse generator body 101, and the water inlet pipe 102 is connected to the water inlet area 111.
[0035] Furthermore, the water distribution system 1001 also includes four drain pipes 116 connected to both sides of the outer end face of the connecting pipe 107. The drain pipes 116 are symmetrically arranged, and two branch water pipes 118 are connected to the tail end of the drain pipes 116. The branch water pipes 118 are provided with four inner ring drain nozzles 122 on one side of each other. The four inner ring drain nozzles 122 are distributed in concentric circles, and their openings face clockwise or counterclockwise.
[0036] Furthermore, the branch water pipes 118 are connected to each other on one side away from each other by two symmetrically positioned support pipes 117. Eight outer ring drainage nozzles 119 are installed at the top of the support pipes 117 and at both ends of the branch water pipes 118. The eight outer ring drainage nozzles 119 discharge water tangentially, and are clockwise or counterclockwise, just like the inner ring drainage nozzles 122.
[0037] It should be further explained that the inner ring drainage nozzle 122 is located in the inner ring, and the outer ring drainage nozzle 119 is located in the outer ring. When the four inner ring drainage nozzles 122 are activated, the water flow inside the inner ring flows in an inner ring direction. When the outer ring drainage nozzles 119 are activated, the water flow in the outer ring flows in an outer ring direction. The water flow direction of the inner ring and the outer ring is the same. The drainage pipes 116 on adjacent sides form a flowing water ring with the water flow directions being clockwise and counterclockwise, respectively, to prevent the water flow in adjacent areas from canceling each other out.
[0038] It is worth further explaining that the distribution of the connecting pipe 107, the drain pipe 116 and the branch water pipe 118 can be adjusted according to the hydrolysis acidification tank 108, and finally form a ring distribution of inner ring drainage nozzles 122 and outer ring drainage nozzles 119.
[0039] When using this solution, firstly, four water distribution systems 1001 are installed in the hydrolysis acidification tank 108, and the pulse generator body 101 is installed above the hydrolysis acidification tank 108. After the support legs 104 provide stable support, the sewage pipe to be treated is connected to the inlet pipe 102, allowing water to enter the inlet area 111 through the inlet pipe 102. At this time, the water level slowly rises to the top of the pulse generator pipe. During this process, the air in the section between the pulse generator pipe 110 and the bell jar 112 is discharged through the water seal groove 123 at the bottom of the pulse generator pipe 110. As the water level in the inlet zone 111 continues to rise, water begins to overflow from the top of the pulse generating tube 110 into the receiving zone 121. Once a certain volume of water is reached, a water plug flow is formed, which carries out all the air in the bell jar 112 and the pulse generating tube 110, forming a siphon. The water in the inlet zone 111 quickly enters the receiving zone 121. As the water in the inlet zone 111 is rapidly discharged, the liquid level gradually decreases. When the liquid level drops to the bottom opening of the pulse breaking tube 114, air enters the bell jar 112, the siphon is broken, and the water level in the inlet zone 111 begins to rise again, entering the next pulse water discharge process.
[0040] Water that quickly enters the receiving area 121 is guided through the outlet pipe 103 into the hydrolysis acidification tank 108 and then into the connecting pipe 107. At this time, the water flows through the inner ring of the inner ring drainage nozzles 122 on each side and through the outer ring of the outer ring drainage nozzles 119. When the four inner ring drainage nozzles 122 are activated, the water inside flows in an inner ring direction. When the outer ring drainage nozzles 119 are activated, the water flows in an outer ring direction. The water flow direction of the inner and outer rings is the same. The drainage pipes 116 on adjacent sides form a flowing water ring with the water flow direction being clockwise and counterclockwise, respectively. The rotation of the formed water flow enhances mass transfer acidification and prevents siltation.
[0041] This solution, through a pulse generation structure and a three-dimensional rotating water distribution system, can achieve gradient control of the pulse water flow velocity in the hydrolysis acidification tank, effectively improving the mixing efficiency.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
