Embodiment 1

[0047] Such as Figure 1 to Figure 3 As shown, the water collection funnel 4 is arranged in the water collection well 3, and one end of the top of the water collection funnel 4 is connected to the drainage channel 2, and the bottom of the water collection funnel 4 is connected to the first water pump 5 through a pipeline, and the first water pump is connected to the sedimentation tank 6 through a pipeline, and the sedimentation tank 6 is connected to the water collecting tank 7 through pipelines, and the water collecting tank 7 is respectively connected to the clean water tank 13 and the second water pump 8 through pipelines, and the second water pump 8 is connected to the source of the drain 2 through pipelines.

[0048] In this embodiment, cement retarder is added in proportion to the water in the clean water tank 13 .

[0049] In this embodiment, the interior of the settling tank 6 is evenly sprayed with low-temperature waterproof paint. When the low-temperature waterproof ...

Embodiment 2

[0055] Such as Figure 4 As shown, the sewage recycling system for water-stop curtain grouting production includes:

[0056] Water level monitoring module 15: connected with the main control module 18, including the first water level monitor 10 and the second water level monitor 11 and ancillary devices, used to monitor the water level in the water collecting funnel 4, and transmit the water level information to the main control module .

[0057] Conductivity detection module 16 : connected to the main control module 18 , including auxiliary devices such as a conductivity meter and a bracket, for monitoring the conductivity in the clean water tank 13 .

[0058]Flow control module 17: connected to the main control module 18, including the second water pump 8, the first water pump 5, the third water pump 14 and accessory devices, used to control the water volume in the drainage channel 2 and the water collecting funnel 4.

[0059] Main control module 18: including the controll...

Embodiment 3

[0063] Such as Figure 5 As shown, the control methods of the water-stop curtain grouting production sewage recycling system include:

[0064] S01: The conductivity detection module detects the conductivity in the clean water tank. When the conductivity meets the standard requirements, the main control module controls the third water pump in the clean water tank to inject water into the water collection tank. If the conductivity does not meet the standard requirements, continue to supply clean water Add cement retarder to the box.

[0065] S02: The main control module controls the second water pump to turn on, and presses the water in the water collection tank into the drain through the pipeline.

[0066] S03: The water in the drainage channel washes away the cement slurry flowing out under the water-stop curtain. When the water contains cement slow-release agent, the cement slurry coagulates at a slower rate and collects together into the water collection funnel in the water...

Abstract

The invention belongs to the technical field of sewage treatment, and discloses a water-stop curtain grouting production sewage recycling control system and method. The water-collecting funnel is arranged in the water-collecting well, and one end of the top of the water-collecting funnel is connected to a drainage channel, and the bottom of the water-collecting funnel is connected through a pipeline. The first water pump, the first water pump is connected to the sedimentation tank through the pipeline, the sedimentation tank is connected to the water collection tank through the pipeline, the water collection tank is respectively connected to the clean water tank and the second water pump through the pipeline, the second water pump, the first water pump and the third water pump, the second water pump is passed through The pipe is connected to the source of the drain. The invention reduces the waste of water resources and reduces engineering expenses by recycling water. The present invention is simple in structure, easy to implement, and suitable for popularization and use. By using the cement retarder to slow down the coagulation speed of cement, the cement coagulates in the sedimentation tank, reduces the coagulation of cement in other equipment, and reduces the cleaning workload. The low-temperature waterproof coating used, It can make the sedimentation tank clean the sedimented cement thoroughly, with high efficiency and saving labor cost.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a water-stop curtain grouting production sewage recycling control system and method. Background technique [0002] At present, the closest existing technology: water conservancy and hydropower construction is often accompanied by damage to the environment. In recent years, the idea of ​​doing a good job in environmental protection and water conservation has been deeply extended to various water conservancy and hydropower construction enterprises. [0003] The current curtain grouting construction often involves cross flow of sewage, which destroys the water environment of the involved waters; especially for the construction in the scenic area, the water quality requirements of the involved waters are higher. In order to ensure the water quality requirements of water areas, it is necessary to increase investment in sewage treatment and discharge. [0004] The...
