The upper part of the tank body 1 is a clear water area 3 which is used for separating the waste water after hydrolytic acidification from the activated sludge. The lower part of cell body 1 is mud district 2, mud district 2 is filled with activated sludge, and, mud district 2 is equipped with water distribution mechanism, water distribution mechanism intercommunication inlet tube 4 for input pending waste water in to cell body 1, through activated sludge's hydrolytic acidification, with the indissolvable organic matter degradation of waste water for easy soluble organic matter or micromolecule, reduce the COD value of water, the subsequent oxidation treatment of being convenient for. The bottom of the sludge area 2 is also provided with a sludge outlet 6, and the sludge outlet 6 is communicated with the sludge treatment mechanism through a pipeline and is used for discharging the activated sludge in the sludge area 2 when the sludge is replaced.

Specifically, the water distribution mechanism comprises a rotating shaft 7 and a water distribution pipe 8 arranged on the rotating shaft 7. The rotating shaft 7 is a hollow tubular shaft, and two ends of the rotating shaft 7 penetrate through the side wall of the tank body 1 and are erected in the sludge area 2 in the tank body 1. One end of the rotating shaft 7 is open and communicated with the water inlet pipe 4, the other end of the rotating shaft is a closed end and is in transmission connection with the driving mechanism 9 through a coupler, and the rotating shaft 7 can rotate through the driving of the driving mechanism 9. The rotating shaft 7 penetrates through the side wall of the tank body 1 and is provided with a sealing ring 10, and the arranged sealing ring 10 can prevent water in the tank body 1 from leaking. The junction of the rotating shaft 7 and the water inlet pipe 4 is also provided with a rotating pipe joint 11, and the rotating shaft 7 can be communicated with the water inlet pipe 4 and can rotate through the rotating pipe joint 11. The water distribution pipe 8 is communicated with the inner cavity of the rotating shaft. The water distribution pipe is provided with a water outlet hole 18, and the direction of the water outlet hole 18 is opposite to the rotating direction of the rotating shaft 7.

When the device works, the rotating shaft 7 rotates under the driving of the driving mechanism 9, so that the water distribution pipe 8 rotates along with the rotating shaft, the activated sludge is stirred, the activated sludge is prevented from precipitating, meanwhile, the wastewater input by the water inlet pipe 4 flows out from the water distribution pipe 8 through the rotating shaft 7, the wastewater can be input while stirring the activated sludge, and the position of the water outlet is changed, so that the wastewater can be more uniformly distributed in the activated sludge, and the hydrolysis acidification efficiency of the activated sludge on the wastewater is improved; and, because the direction that waste water flows out of the water outlet hole 18 is opposite to the rotating direction of the rotating shaft 7, the waste water distributor has a pushing effect on the water distribution pipe 8, and the energy consumption of the driving mechanism 9 can be further reduced.

The hydrolysis acidification treatment device with the structure can be used for stirring the activated sludge while distributing the activated sludge in the pool body 1 by arranging the stirring water distribution mechanism, not only can prevent the activated sludge from depositing, but also can ensure that the input wastewater is more uniformly distributed in the activated sludge, accelerates the hydrolysis acidification efficiency of the wastewater and improves the purification effect.

It should be noted that the tank body 1 may be provided with a plurality of water distribution mechanisms according to the size of the volume or the bottom area, and at the same time, the number of the water distribution mechanisms is determined by the number of the branch water distribution pipes, so that the wastewater at the water inlet is distributed to each water distribution mechanism through the branch water distribution pipes.

In some embodiments, in the hydrolysis acidification processing apparatus with the above structure, the rotating shaft 7 is further provided with the stirring blades 12, the stirring blades 12 are circumferentially and uniformly distributed on the rotating shaft 7, and when the rotating shaft 7 rotates, the area of the flaky stirring blades 12 is large, so that compared with the water distribution pipe 8, the hydrolysis acidification processing apparatus can better turn over the activated sludge, and the activated sludge and the wastewater can be better mixed and contacted.

In the hydrolysis acidification process, the rotation of the rotating shaft 7 is slower, because if the stirring speed is too high, the fluctuation of the upper clear water area 3 is easy to be too large, so that the activated sludge and water are difficult to be layered, and the activated sludge and the water overflow together, on one hand, the subsequent purification difficulty is improved, on the other hand, the activated sludge is lost, the supply amount of the activated sludge is increased, and the cost is improved. Therefore, the rotation speed of the rotating shaft 7 is usually adjusted so that the activated sludge does not deposit, but does not enter the upper clear water zone 3. The spiral stirring blade 12 can increase the contact area between the stirring blade 12 and the activated sludge, so that the stirring effect is better under the condition of the same stirring speed. Further, spiral helicine stirring leaf 12 still has the effect of carrying mud, and when changing activated sludge, quick rotatory pivot 7, spiral helicine stirring leaf 12 have the conveying effect, carry activated sludge to the mud discharge port 6 that the cell body 1 below set up in, improve the efficiency of decontaminating.

Meanwhile, the baffle 13 can buffer the kinetic energy generated by the sludge zone 2, so that the water flow of the upper clear water zone 3 is kept in a stable state, and the separation of water and activated sludge is facilitated.

As a further improvement, the baffle 13 is a baffle 13 which is arranged obliquely downwards relative to the horizontal plane, that is, the fixed end of the baffle 13 is higher than the free end, so as to form a state of being inclined downwards from the fixed end, when the water carrying the activated sludge flows along the tortuous upward water flow path, the inclined baffle 13 can enable the activated sludge to better slide down and then return to the bottom sludge area 2, so as to reduce the loss of the activated sludge.

In other embodiments, a grid 14 is arranged between the sludge area 2 and the clear water area 3, the grid 14 can reduce the influence on the clear water area 3 when the sludge area 2 is stirred, and on the other hand, the grid 14 can accelerate the separation of water and activated sludge when the hydrolyzed and acidified wastewater flows upwards.

As a further improvement, a filter layer 15 is arranged on the grid 14, the filter layer 15 is filled with fillers having a filtering effect, the fillers can be spherical pebbles, ceramic balls or other spherical objects, the accumulated spherical fillers can form water flow gaps, and when wastewater treated by activated sludge passes through the water flow gaps, the activated sludge is intercepted, so that a filtering effect is achieved, and water is separated from the activated sludge.
