Abstract
Description
Technical Field
[0001] The utility model relates to a device for deep treatment and recycling of domestic sewage. Background Art
[0002] In the past, when the integrated domestic sewage treatment device was in operation, domestic sewage was treated by the integrated domestic sewage treatment device and then entered the coal-water separation clear water tank for use as the flushing water of the coal conveying system. In recent years, due to the increase in the domestic sewage volume in the factory area, the domestic sewage volume has also increased correspondingly, resulting in water swelling in the coal-water separation system. Therefore, a device for deep treatment and recycling transformation of domestic sewage is added to further treat and recycle the water treated by the integrated domestic sewage treatment device. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide a device for deep treatment and recycling of domestic sewage, which can recycle some of the clear water generated by the integrated domestic sewage treatment device and effectively improve the utilization rate of water resources. The technical solution of the utility model is: a device for deep treatment and recycling of domestic sewage, the regulating tank (1) is connected to the front-end treatment tank (2) of the membrane bioreactor through a submersible pump (11). A liquid level float (10) is arranged in the regulating tank (1). The submersible pump (11) starts according to the liquid level float in the regulating tank (1) to pump water to the front-end treatment tank (2). The water in the front-end treatment tank (2) overflows and flows into the reaction tank (3). The blower (9) blows air into the regulating tank (1) and the reaction tank (3). The aerated water passes through the reaction membrane (4) in the reaction tank (3). The suction pump (5) on the pipeline pumps water to the water-using tank (6) according to the value of the pressure transmitter. The water in the water-using tank (6) is pumped to the water-using point by a pump again. During the start-up process of the suction pump (5), the disinfection device (7) continuously disinfects the produced water, and the liquid in the cleaning water tank (8) backwashes the reaction membrane (4) in the reaction tank (3).
[0004] The working principle of the utility model:
[0005] The raw water of the utility model passes through the front-end treatment tank (2) and the reaction tank (3) and is aerated by the blower (9), and then enters the reaction membrane (4) to further purify the water. While the water is pumped out by the suction pump (5), the disinfection device (7) continuously disinfects the produced water. There is a pressure transmitter at the inlet of the suction pump (5). When the value of the pressure transmitter reaches the set value, the suction pump (5) will automatically stop, and the cleaning device (8) will start to clean the membrane. The whole set of equipment can realize self-starting and self-stopping.
[0006] The technical effect of the utility model:
[0007] The utility model designs a deep treatment and recycling device for domestic sewage. The domestic sewage first enters the regulation tank. A liquid level float is arranged in the regulation tank. When the water level rises to the position of the float, the water pump in the regulation tank will automatically start and stop, and at the same time, the blower will also start. The blower continuously conveys gas to the front-end treatment tank and the reaction tank for continuous aeration, and the water quality passes through the reaction membrane. The suction pump is equipped with a pressure sensor and a solenoid valve to realize the automatic start and stop of the suction pump. The utility model improves the utilization rate of domestic sewage and greatly saves water resources. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is the working principle diagram of the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0009] As Figure 1 shown, a deep treatment and recycling device for domestic sewage, the regulation tank 1 is connected to the front-end treatment tank 2 of the membrane bioreactor through the submersible pump 11. A liquid level float 10 is arranged in the regulation tank 1. The submersible pump 11 starts the submersible pump 11 according to the liquid level float in the regulation tank 1 and pumps the water to the front-end treatment tank 2. The water in the front-end treatment tank 2 overflows and flows into the reaction tank 3. The blower 9 blows air into the regulation tank 1 and the reaction tank 3. The aerated water passes through the reaction membrane 4 in the reaction tank 3. The suction pump 5 on the pipeline will pump the water to the water use tank 6 according to the value of the pressure transmitter. The water in the water use tank 6 is then pumped to the water use point by the pump. During the start-up process of the suction pump 5, the disinfection device 7 will continuously disinfect the produced water, and the liquid in the cleaning water tank 8 will backwash the reaction membrane 4 in the reaction tank 3.
[0010] The regulation tank 1 of the utility model is an integrated domestic system. After the incoming water passes through the front-end treatment tank 2 and the reaction tank 3 and is aerated by the blower, it enters the reaction membrane 4 to further purify the water. While the water is pumped out by the suction pump 5, the disinfection device 7 will continuously disinfect the produced water. There is a pressure transmitter at the inlet of the suction pump 5. When the value of the pressure transmitter reaches the set value, the suction pump 5 will automatically stop, and the cleaning device 8 will start to clean the membrane. The whole set of equipment can realize automatic start and stop, improve the utilization rate of domestic sewage, and greatly save water resources.
