Preferably, the multistage flow channel comprises a first flow channel 2, a second flow channel 3, a third flow channel 4 and a fourth flow channel 5 which are communicated in sequence. The first flow channel 2, the second flow channel 3, the third flow channel 4 and the fourth flow channel 5 are arranged in an S shape, so that the liquid flowing time and the disinfection time are increased, the disinfection effect is improved, and meanwhile, the occupied area is not increased.

Preferably, the liquid level height of the first flow channel 2, the liquid level height of the second flow channel 3, the liquid level height of the third flow channel 4 and the liquid level height of the fourth flow channel 5 are sequentially reduced, and the difference between the liquid level heights of the adjacent flow channels is 50mm-300 mm. The liquid level difference between adjacent runners is set, the impact force on the next runner when the previous runner enters the next runner through the overflow plate 1 is increased, the liquid mixing effect is improved, the disinfection effect is enhanced, and the sedimentation at the bottom of the pool is reduced.

Preferably, the overflow plates 1 are suspended to communicate the bottoms of the adjacent flow channels. When the liquid of a preceding runner flows through overflow plate 1 between preceding runner and the back runner, the liquid of runner bottom can be followed overflow plate 1 lower part and normally flowed into back runner, and the liquid on runner upper portion overflows through overflow plate 1 and gets into back runner, improves liquid mixing effect, when extension disinfection time, is difficult for taking place the sediment.

Preferably, a stirrer 11 is arranged at the water outlet end of the overtaking tank 9, and the stirring direction of the stirrer 11 is opposite to the liquid flowing direction. When the surpassing pool is used for disinfection, the liquid is ensured to be fully mixed, the disinfection time is prolonged, and the disinfection effect is improved.

Preferably, the overtaking tank 9 is provided with a partition 15 for prolonging the flowing time of the liquid in the overtaking tank when the overtaking tank is used for disinfection, thereby increasing the disinfection time and improving the disinfection effect.

The liquid in the surpassing pool 9 flows from the liquid flow passage, the liquid flow is increased, the disinfection time is prolonged, and the disinfection effect is improved.

Preferably, the number of the partition boards 15 is 2-3, the partition boards 15 are distributed in the surpassing pool 9 at intervals along the water inlet end of the surpassing pool 9 to the water outlet end, the adjacent partition boards 15 are respectively arranged on the opposite pool walls of the surpassing pool 9, and when the surpassing pool is used for disinfection, an S-shaped liquid flow channel is formed in the surpassing pool 9, so that the liquid flow path is increased, the flow time is prolonged, the disinfection time is prolonged, and the disinfection effect is improved.

Preferably, the wall of the overtaking pool 9 is provided with a backwater pipe 10. The liquid part after the disinfection treatment enters the surpassing pool 9 and can be reused through the reused water pipe 10.

The working process of the contact disinfection tank of the embodiment is as follows:

when the sewage is disinfected during contact disinfection, the first gate 6 between the water inlet tank 7 and the first flow channel 2, the fourth gate 14 between the water outlet tank 13 and the fourth flow channel 5 and the third gate 12 between the water outlet tank 13 and the overrunning tank 9 are respectively opened, and the second gate 8 between the water inlet tank 7 and the overrunning tank 9 is closed. Domestic sewage is after the secondary treatment, carry the intake chamber 7 in the disinfection pond through the water pump, liquid enters into first runner 2 after mixing with the disinfectant and disinfects, when the overflow plate 1 of first runner 2 and second runner 3 flows through, the liquid of 1 lower part of overflow plate still normally flows and enters into in the second runner 3, because the liquid level height of first runner 2 is higher than the liquid level height of second runner 3 by 50 ~ 300mm, the upper portion liquid of first runner 2 passes through overflow plate 1 and strikes the mixture to the liquid in the second runner 3, the mixture of the liquid in the second runner 3 has been strengthened effectively, the extension disinfection time, improve the disinfection effect effectively, can slow down the sediment of cell body simultaneously. The mixed liquid passes through the second flow channel 3, the overflow plate between the second flow channel 3 and the third flow channel 4, the overflow plate between the third flow channel 4 and the fourth flow channel 5, the fourth flow channel 5 and the water outlet pool 13 in sequence. Because the third gate 12 between the water outlet pool 13 and the overtaking pool 9 is in an opening state, the liquid part after the disinfection treatment enters the overtaking pool 9, and when the reuse water is needed, the reuse water can be used through the corresponding water pump and the reuse water pipe 10.

When the multistage flow channel is maintained or cleaned, the first gate 6 between the water inlet pool 7 and the first flow channel 2, the fourth gate 14 between the fourth flow channel 5 and the water outlet pool 13 are closed, the second gate 8 and the third gate 12 at two ends of the surpassing pool are opened, and the stirrer 11 in the surpassing pool is opened. At this time, in the water inlet tank 7, the liquid after the secondary treatment is mixed with the disinfectant, enters the surpassing tank 9 through the second gate 8, flows to the water outlet end, and flows into the water outlet tank 13 through the third gate 12. Because the function of the stirrer 11 in the surpassing pool 9, the liquid mixing effect is enhanced, the flowing and disinfection time of the liquid is prolonged, and the disinfection effect is effectively improved. The provision of the partition 15 beyond the basin 9 effectively extends the flow of liquid and the disinfection time, as well as the disinfection effect.
