The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.
Referring to fig. 1, the automatic wastewater recovery device for a micro-filter provided by the invention comprises a micro-filter 1, a buffer water tank 2, a filtering sand box 3, a PLC controller 4, a sewage discharge pipeline 5 and a back flush pipeline 6, wherein the sewage of the micro-filter 1 is communicated with the buffer water tank 2 through a sewage collecting pipe 7, and the buffer water tank 2 is arranged to collect the wastewater generated by back flush of the micro-filter 1 each time, so that the wastewater can be uniformly treated when being accumulated to a certain amount. The bottom of the buffer water tank 2 is of a conical structure, the water pump 9 is communicated to the bottom of the buffer water tank 2, so that accumulated impurities at the bottom of the buffer water tank 2 can automatically gather towards the center under the suction effect of the water pump 9, the phenomenon that the impurities such as fish manure and the like are accumulated at corners and cannot be cleaned is avoided, and the water quality is further polluted. A one-way valve 13 is arranged between the buffer water tank 2 and the water pump 9 to prevent backwash sewage from reversely flowing into the buffer water tank 2. The buffer water tank 2 is made of PE polyethylene, and has excellent service performance such as heat resistance, freezing resistance and corrosion resistance.
The buffer water tank 2 is internally provided with a liquid level sensor 8, the liquid level sensor 8 is used for monitoring the liquid level in the buffer water tank 2 and sending signals to the controller 4, the liquid level sensor 8 comprises a high-level sensor arranged at the top of the buffer water tank 2 and a low-level sensor arranged at the bottom of the buffer water tank 2, when the water level in the buffer water tank 2 reaches the top or the bottom, the corresponding sensors are respectively touched, and corresponding liquid level signals are sent to the controller 4. The buffer water tank 2 is communicated to the water inlet of the filtering sand box 3 through the water pump 9, when a certain amount of sewage is accumulated in the buffer water tank 2, the sewage is conveyed into the filtering sand box 3 through the water pump 9 together in a pressurized mode for filtering, the water outlet of the filtering sand box 3 is provided with the first electric control valve 10 and the second electric control valve 11 in parallel, the first electric control valve 10 is communicated with the micro-filter 1, so that filtered clean water reenters the micro-filter 1 for recycling, and secondary recycling of water resources is achieved. The second electric control valve 11 is communicated with the back flushing pipeline 6, the water inlet of the filtering sand box 3 is also communicated with the sewage pipeline 5 through the third electric control valve 12, and a back flushing system of the filtering sand box 3 is formed by the back flushing pipeline 6 and the sewage pipeline 5 so as to regularly clean the filtering sand box 3. The controller 4 controls the start and stop of the water pump 9 and controls the switch of the first electric control valve 10, the second electric control valve 11 and the third electric control valve 12. The automatic filtration of the sewage of the micro-filter 1 and the back flushing cleaning of the filtering sand box 3 are realized by controlling the water pump 9, the first electric control valve 10, the second electric control valve 11 and the third electric control valve 12.
The invention also provides a use method of the automatic micro-filter wastewater recovery device, which comprises the following steps:
When the micro-filter is normally used, sewage in the micro-filter 1 continuously enters the buffer water tank 2, when the liquid level monitored by the liquid level sensor 8 rises to a first threshold value, namely, when the water level reaches the top of the buffer water tank 2, the high-level sensor is touched, the high-level sensor sends out a corresponding liquid level signal, the controller 4 receives the signal and controls the water pump 9 to start, the electric control valve I10 to open, and the electric control valve II 11 and the electric control valve III 12 to close. At this time, the whole device starts to carry out a sewage filtering program, sewage in the buffer water tank 2 enters the filtering sand box 3 for filtering after being pressurized by the water pump 9, and filtered clear water enters the micro-filter 1 again for recycling through the first electric control valve 10, so that the secondary recycling of water resources is realized.
When the liquid level monitored by the liquid level sensor 8 falls to a second threshold value, namely when the water level falls to the bottom of the buffer water tank 2, the low-level sensor is triggered, the low-level sensor sends out a corresponding liquid level signal, the controller 4 receives the signal and controls the water pump 9 to stop, and meanwhile, the counting module in the controller 4 counts once. At this time, the sewage in the buffer tank 2 is basically pumped out, the water pump 9 also stops working, and the buffer tank 2 continues to collect the sewage discharged from the micro filter 1.
When the counting module counts N times (the counted times can be set according to the dirt condition in the culture pond), a large amount of fish manure and other impurities are accumulated in the filtering sand box 3, the filtering effect is poor, and therefore back flushing cleaning needs to be started, at the moment, the controller 4 controls the first electric control valve 10 to be closed, the second electric control valve 11 and the third electric control valve 12 to be opened, the filtering function is closed, the back flushing pipeline 6 is communicated with the sewage pipeline 5, and a back flushing system of the filtering sand box 3 is formed for cleaning the filtering sand box 3. After a certain time delay, impurities in the filtering sand box 3 are cleaned, then the controller 4 controls the second electric control valve 11 and the third electric control valve 12 to be closed, the back flushing system is closed, and meanwhile, the count of the counting module is cleared, and the next round of filtering and back flushing circulation is waited.
The application obviously reduces the wastewater yield by reutilizing the sewage of the micro-filter 1. Taking an 80 ton flow microfilter as an example, the daily wastewater produced when the recovery device is not installed can reach 4 tons, and the wastewater amount can be reduced by about 80 percent after the wastewater recovery device is installed. The device not only realizes the full automation of the back flushing flow of the filtering equipment, but also effectively reduces the cost expenditure, and provides powerful support for the sustainable development of the aquaculture.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
