Abstract
The invention discloses a suspended filler hydrolysis acidification pool which comprises a pool body, wherein a water inlet pipe and a water outlet pipe are respectively arranged at two ends of the pool body, a guide wall is arranged in the middle of the pool body, flow impellers are respectively arranged at two sides of the guide wall, a guide screen is arranged at the rear end of each flow impeller, suspended fillers are filled in the pool body, and a water outlet interception screen is arranged at the front end of the water outlet pipe in the pool body. The invention adopts plug flow type arrangement, can play a role in water quality regulation, and can reduce the matching arrangement of the pool body; the tank is filled with the suspended filler, and the hydrolyzed sludge is fixed on the suspended filler, so that the requirements of hydrolysis and acidification can be met, a matched sedimentation tank is not needed, sludge backflow is not needed, the occupied area is small, and the energy consumption is low; the triangular diversion screen is arranged at the rear end of the flow pusher, so that the suspended filler can be protected from being damaged by the flow pusher, and the normal operation of the flow pusher can also be protected.
Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a suspended filler hydrolysis acidification tank.
Background
The biodegradability of industrial sewage is poor, the content of nondegradable COD is high, and a hydrolysis acidification tank is usually arranged in the pretreatment stage for improving the biodegradability of the industrial sewage.
The conventional hydrolysis acidification tank is provided with an up-flow hydrolysis acidification tank or a complete mixing hydrolysis acidification tank. The upflow hydrolysis acidification tank does not have a mixing function, cannot have a function of adjusting the quality of inlet water, and meanwhile, in order to ensure the hydrolyzed sludge amount of the upflow hydrolysis acidification tank, the upflow hydrolysis acidification tank is deep, uneven in water distribution and large in head loss, and a sludge discharge facility is needed. The complete mixing type hydrolysis-acidification pool has a water quality adjusting function, but in order to keep the hydrolysis sludge amount in the hydrolysis-acidification pool, the complete mixing type hydrolysis-acidification pool needs a matched sedimentation tank, hydrolysis sludge is refluxed into the hydrolysis-acidification pool after being shunted through sedimentation, a matched sludge discharge facility is needed, the equipment types are multiple, and the operation energy consumption is large.
The person skilled in the art is dedicated to solving the above technical drawbacks.
Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, a technical object of the present invention is to solve the problems mentioned in the above-mentioned background art.
In order to achieve the technical purpose, the invention provides a suspended filler hydrolysis acidification pool which comprises a pool body, wherein a water inlet pipe and a water outlet pipe are respectively arranged at two ends of the pool body, a guide wall is arranged in the middle of the pool body, flow impellers are respectively arranged at two sides of the guide wall, a guide screen is arranged at the rear end of each flow impeller, suspended fillers are filled in the pool body, and a water outlet interception screen is arranged at the front end of the water outlet pipe in the pool body.
Preferably, the shape of the tank body is oval.
Preferably, the shape of the diversion screen is triangular.
Preferably, the shape of the outlet water intercepting screen is arc-shaped.
The invention has the beneficial effects that:
due to the structural design, the plug-flow type arrangement is adopted, so that the function of water quality regulation can be achieved, and the matching arrangement of the pool body can be reduced;
the tank is filled with the suspended filler, and the hydrolyzed sludge is fixed on the suspended filler, so that the requirements of hydrolysis and acidification can be met, a matched sedimentation tank is not needed, sludge backflow is not needed, the occupied area is small, and the energy consumption is low;
the triangular diversion screen is arranged at the rear end of the flow pusher, so that the suspended filler can be protected from being damaged by the flow pusher, and the normal operation of the flow pusher can also be protected.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
In the figure: 1 pool body, 2 water inlet pipes, 3 water outlet pipes, 4 flow guide walls, 5 flow pushers, 6 flow guide screens, 7 suspended fillers and 8 water outlet intercepting screens.
Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, the features and the effects of the present invention.
Example (b):
as shown in fig. 1, a hydrolytic acidification tank for suspended fillers comprises a tank body 1, wherein the tank body 1 is of an oval structure, a water inlet pipe 2 and a water outlet pipe 3 are respectively arranged at two ends of the tank body 1, a flow guide wall 4 is arranged in the middle of the tank body 1, flow pushers 5 are respectively arranged at two sides of the flow guide wall 4, a triangular flow guide screen 6 is arranged at the rear end of each flow pusher 5, suspended fillers 7 are filled in the tank body 1, and an arc-shaped water outlet interception screen 8 is arranged at the front end of the tank body 1, which is located at the water.
Specifically, the plug-flow type arrangement is adopted, so that the function of water quality regulation can be achieved, and the matching equipment of the pool body 1 can be reduced.
Specifically, the hydrolytic acidification requirement can be met by fixing the hydrolytic sludge on the suspension filler, a matched sedimentation tank is not needed, sludge backflow is not needed, the occupied area is small, and the energy consumption is low.
Specifically, the triangular diversion screen 3 is arranged at the rear end of the flow pusher 5, so that the suspended filler 7 can be protected from being damaged by the flow pusher 5, and the normal operation of the flow pusher 5 can also be protected.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
