Description

Supernatant and slurry shunting pipeline structure for SBR reaction tank

Technical Field

The utility model relates to the technical field of environmental engineering, in particular to a supernatant and slurry shunt pipeline structure for an SBR reaction tank.

Background

The wastewater after biological contact oxidation treatment must be further treated by adopting a sequential batch activated sludge process (SBR) to reach the discharge standard.

The mechanism of removing organic matters by the SBR method is as follows: a certain amount of active microorganisms (active slurry) are cultured and domesticated in advance in the reaction period, when the wastewater enters a reactor to be mixed and contacted with the active slurry and has oxygen, the microorganisms metabolize by using organic matters in the wastewater to convert organic pollutants into inorganic matters such as 2CO, OH2 and the like; simultaneously, the microbial cells proliferate, and finally, the microbial cell substances (active serous fluid) are separated from the water precipitate, and the wastewater is treated. The SBR method generally requires the use of an SBR tank, the conventional small-sized SBR tank adopts the structure shown in figure 4, and the SBR tank is kept stand and drained after biochemical reaction. When the water in the reaction tank is excessive, the water discharge is controlled to be started. When more slurry is left in the reaction tank, the slurry discharge (two) is started. Two sets of sewage systems are required to meet the function requirements, and are respectively controlled by two electromagnetic valves, so that more pipes are required. When the water level in the pool is higher, any valve is damaged, and the corresponding valve can be replaced after the water needs to be emptied, so that the maintenance is inconvenient.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, a supernatant and slurry diversion pipeline structure for an SBR reaction tank comprises an SBR tank body 1 for wastewater treatment, a second diversion pipe 5 is embedded on the side wall of the upper end of the SBR tank body 1, a drain pipe 3 is fixed at one end of the second diversion pipe 5 extending into the SBR tank body 1 through a tee joint for discharging redundant supernatant, a second slag blocking pipe 7 is fixed above the drain pipe 3 for preventing the drain pipe 3 from being blocked by impurities floating on the surface of the supernatant, meanwhile, the second slag blocking pipe 7 is communicated with air above the SBR tank body 1 and can destroy the siphon effect formed in the backflow process, a discharge pipe joint 4 is fixed at the other end of the second diversion pipe 5 through a tee joint, a first diversion pipe 6 is fixed above the discharge pipe joint 4, a sludge discharge pipe 2 is fixed at the other end of the first diversion pipe 6 through a tee joint for discharging slurry at the bottom of the tank, a first slag blocking pipe 8 is fixed above the sludge discharge pipe 2, a slurry emptying, the inside stability of destruction reaction tank for avoiding supernatant surface showy debris to block up mud pipe 2, the siphon effect that the reflux process formed can be destroyed to the air intercommunication of first fender sediment pipe 8 and SBR cell body 1 top simultaneously, avoids with the thick liquid evacuation in the SBR cell body 1.
