DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-3 This application is described in further detail.
[0030] The present application embodiment discloses a sewage plant tail water recycling system. Figure 1 and Figure 2The sewage treatment plant tail water reuse system includes a sewage treatment plant tail water reuse system, including a metering channel 1, a reuse pump house 2, a dehydration workshop 3 and an aerobic pool 4. The sewage treatment plant tail water is discharged into the metering channel 1 after being disinfected in the disinfection pool. The metering channel 1 is connected with a drainage pipe 11 and a reuse water inlet pipe 12. The drainage pipe 11 is externally connected to a rainwater culvert. The end of the reuse water inlet pipe 12 away from the metering channel 1 is connected with the reuse pump house 2. A reuse water pump 21 is arranged in the reuse pump house 2. The outlet of the reuse water pump 21 is connected with a water pump pipe 22. The outlet of the water pump pipe 22 is connected with a reuse water outlet pipe 23. The first branch pipe 24, the second branch pipe 25 and the third branch pipe 26 are connected to the reuse water outlet pipe 23. The first branch pipe 24 is used for road washing, green belt irrigation or ecological water replenishment; the second branch pipe 25 is connected to the dehydration workshop 3 for water supply in the dehydration workshop 3; the third branch pipe 26 is connected to the aerobic pool 4 for defoaming in the aerobic pool 4.
[0031] After the disinfected tail water from the sewage treatment plant enters the metering channel 1, a part of it enters the rainwater culvert through the drainage pipe 11 for discharge, and the other part enters the reuse pump room 2 through the reuse water inlet pipe 12, and is pumped to the reuse water outlet pipe 23 by the reuse water pump 21, and then transported to various water use points through the first branch pipe 24, the second branch pipe 25 and the third branch pipe 26, which facilitates the multi-purpose reuse of tail water and saves water resources.
[0032] Reference Figure 1 and Figure 2 A guardrail 27 is fixedly provided around the top of the reuse pump room 2, which helps to improve the safety of on-site personnel walking on the top of the reuse pump room 2. The reuse water pump 21 is a lifting pump. The reuse water pump 21 is arranged at the bottom of the reuse pump room 2, and the water pump pipe 22 extends to the upper side of the reuse pump room 2. The reuse water pump 21 is arranged at the bottom of the reuse pump room 2, and can pump out as much water as possible in the reuse pump room 2 to improve the utilization rate of tail water. One side of the bottom of the reuse pump room 2 is recessed downward to form a water collection tank 5, and the reuse water pump 21 is arranged in the water collection tank 5. The water in the reuse pump room 2 can preferentially enter the water collection tank 5 with a smaller space, and can further pump out as much water as possible in the reuse pump room 2, thereby further improving the utilization rate of tail water.
[0033] Example 2
[0034] The difference between the present embodiment and embodiment 1 is that, Figure 3A partition plate 6 is provided in the middle of the reuse pump room 2, and the partition plate 6 divides the interior of the reuse pump room 2 into a first chamber 7 and a second chamber 8. The tops of the first chamber 7 and the second chamber 8 are connected, the reuse water inlet pipe 12 is connected to the first chamber 7, and the reuse water pump 21 is arranged in the second chamber 8. After the tail water enters the reuse water inlet pipe 12, it first enters the first chamber 7, and after the tail water level in the first chamber 7 rises to the top of the partition plate 6, it overflows into the second chamber 8, and then the reuse water pump 21 is pressurized and pumped. The tail water first enters the first chamber 7, which can make the remaining impurities in the tail water preferentially deposited at the bottom of the first chamber 7, improve the cleanliness of the tail water entering the second chamber 8, thereby reducing the possibility of impurities blocking the reuse water pump 21, and further improving the service life of the reuse water pump 21.
[0035] Reference Figure 3 The bottom wall in the reuse pump room 2 is inclined, and the highest end of the bottom wall of the reuse pump room 2 is closer to the reuse water inlet pipe 12 than the lowest end. Impurities deposited at the bottom of the first chamber 7 and the second chamber 8 can be gathered on one side, which is convenient for cleaning impurities in the first chamber 7 and the second chamber 8.
[0036] The implementation principle of a sewage treatment plant tail water reuse system in an embodiment of the present application is as follows: after the sewage treatment plant tail water enters the metering channel 1 for disinfection, a part of it enters the rainwater culvert through the drainage pipe 11 for discharge, and the other part enters the first chamber 7 through the reuse water inlet pipe 12. After the tail water level in the first chamber 7 rises to the top of the partition plate 6, it overflows into the second chamber 8, and then enters the sump 5, and then is pressurized and pumped to the reuse water outlet pipe 23 by the reuse water pump 21, and then transported to various water use points through the first branch pipe 24, the second branch pipe 25 and the third branch pipe 26, so as to facilitate the multi-purpose reuse of tail water and save water resources.
