The pretreatment process has a development history of many years. During the development process over the years, through the joint efforts of countless water treatment technicians, various modes have evolved. However, due to the characteristics of pollutants in sewage, for pollutants that are difficult to be biochemically treated, the hydrolysis acidification process, as a treatment process with strong ability to improve the biodegradability of sewage, has very excellent effects. Therefore, the hydrolysis acidification process plays an extremely important role in the pretreatment of sewage with difficult biodegradation.
[0003] In the existing hydrolysis acidification process, traditional multi-point water distribution or single-point water distribution is mostly adopted, with poor hydraulic flow pattern, no effective hydraulic stirring effect, or a stirring device needs to be set in the pool body to prevent sediment deposition in the hydrolysis acidification system, resulting in high energy consumption during daily operation.

Detailed implementation manners
[0013] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention will be further described below in conjunction with specific embodiments. However, the specific embodiments cited are only for the illustration of the present invention and do not limit the present invention.
[0014] As Figures 1 to 4 shown, the hydrolysis and acidification tank 1 is divided into two groups, which is rectangular as a whole, and the bottom of the tank is connected. At the top between the two groups of tank bodies is the water collection channel 5. Water collection weir plates are also provided on both sides of the water collection channel 5. By adjusting the water collection weir plates, the water outlet of the two tanks is made uniform. One end of the water collection channel 5 is provided with a water outlet pipe 10. The sewage in the hydrolysis and acidification tank 1 is discharged from the tank through the water outlet pipe 10. A pulse water distributor 2 is provided at the top of the hydrolysis and acidification tank 1. The pulse water distributor 2 is connected to the water inlet pipe 7. The sewage at the front end enters the pulse water distributor 2 through the water inlet pipe 7 and then enters the hydrolysis and acidification tank 1. The pulse water distributor 2 is connected to the pulse water distribution pipeline 3 arranged at the bottom inside the hydrolysis and acidification tank 1. The pulse water distribution pipeline 3 is located below the perforated sludge discharge pipeline 4, which can avoid the siltation of the sludge at the bottom of the tank. Both the pulse water distribution pipeline 3 and the pulse water distributor 2 serve different ranges in groups.
[0015] The perforated sludge discharge pipeline 4 is arranged at the bottom inside the hydrolysis and acidification tank 1. Like the pulse water distributor 2, the perforated sludge discharge pipeline 4 serves different ranges in groups. The perforated sludge discharge pipeline 4 inside a single group of hydrolysis and acidification tanks 1 is connected to the main sludge discharge pipe 12 for sludge discharge. By opening and closing the solenoid valve 11 installed on the main sludge discharge pipe 12 outside the tank body of the hydrolysis and acidification tank 1, the sludge discharge action is completed. The perforated sludge discharge pipeline 4 is uniformly arranged at the bottom of the hydrolysis and acidification tank 1 and is located above the pulse water distribution pipeline 3. Through the main sludge discharge pipe 12, the sludge in the hydrolysis and acidification system 1 is discharged from the hydrolysis and acidification system under the action of hydraulic static pressure, and no additional power is required for sludge discharge.
[0016] A manhole 8 and an observation hole 9 are opened at the top of the hydrolysis and acidification tank 1; a sludge level gauge is also provided in the hydrolysis and acidification tank 1. The electric valve on the main sludge discharge pipe 12 is adjusted according to the sludge volume to control the sludge concentration in the hydrolysis and acidification tank 1.
[0017] The aperture of the perforated sludge discharge pipeline 4 is 30 mm, and it is arranged at an angle of 45° above the two sides of the pipeline with a spacing of 300 mm. The perforated sludge discharge pipeline 4 is arranged according to the tank type structure of the hydrolysis and acidification tank 1.
[0018] The combined packing 6 adopts finished packing, which is installed in the main reaction area at the middle position of the hydrolysis acidification tank 1, above the pulse water distribution pipeline 3 and the upper area of the perforated sludge discharge system and below the water collection channel 5. It has good water distribution and gas distribution performance, is easy to form a film, and can increase the attachment area of microorganisms, enhancing the treatment effect of the hydrolysis acidification system.
[0019] The present invention solves the problem of uneven water distribution in the traditional hydrolysis acidification system. The traditional hydrolysis acidification system only uses water distribution pipes for multi-point water distribution, with slow water flow and easy sediment deposition at the bottom of the tank. After using the pulse water distributor, it not only plays a role in water distribution but also has a hydraulic stirring effect, preventing sediment deposition at the bottom of the tank and improving the energy utilization rate at the same time. The adopted hydrostatic pressure sludge discharge does not require power equipment for sludge discharge, reducing the overall energy consumption of the system. The added combined packing increases the attachment effect of microorganisms and improves the hydrolysis acidification effect.
[0020] Through the implementation and arrangement of the present invention, it is possible to improve the quality and efficiency of the hydrolysis acidification process in the biological pretreatment process, reduce energy consumption, and improve the treatment efficiency through process optimization.
