The same purpose of setting the second liquid level detection module is also to prevent the situation that the water level is too low to cause complete cleaning, because if the water level in the drainage well V8 is too low, enough water cannot be extracted to backwash the sand filter tower 8 or the activated carbon tower 9, and therefore, when the water level in the drainage well V8 is detected, the setting needs to be carried out according to the water quantity required by cleaning the sand filter tower 8 and the activated carbon tower 9 once. When the sand filtration tower 8 or the active carbon tower 9 is backwashed, the starting conditions are as follows: 1. a liquid level detection state; 2. whether the backwashing time of the sand filtration tower 8 or the activated carbon tower 9 is reached; 3. whether the operating pressure of the sand filtration tower 8 or the activated carbon tower 9 reaches the set value of the backwashing pressure or not. And controlling to start the backwashing operation only when the conditions are met.

More preferably, the water storage tank further comprises a control module electrically connected to the first display module and the second display module, wherein the first display module is used for displaying the liquid level height in the water storage tank V7; the second display module is used for displaying the liquid level height of the relief well V8. The liquid level height in the water storage tank V7 and the releasing well V8 can be visually displayed through the display module, so that a user can have visual feeling. When the system control operation is carried out, two modes can be selected, one mode is an automatic mode, the other mode is a manual mode, namely, the electric control operation of all devices in the system can be automatically carried out, and the manual control operation can be conveniently carried out by a worker according to the favorite mode. Most preferably, in the embodiment of the utility model, the automatic control mode is adopted, and through the operation, the personnel cost of an enterprise can be reduced, so that the enterprise can use the device on duty without training corresponding personnel; the overall stability is also better.

More preferably, the first delivery pump 71, the second delivery pump 72 and the reverse water pump are electrically connected to the control module through corresponding switch modules, and the switch modules are used for switching the first delivery pump 71, the second delivery pump 72 and the reverse water pump to any one of a manual mode, an automatic mode or a shutdown mode. The monitoring module is electrically connected with the control module and used for displaying the state of each device in the system. That is the embodiment of the utility model provides an in the delivery pump can adopt syllogic control mode to control the delivery pump, can switch to automatic, manual or closed condition, when being in closed condition, then can't start corresponding equipment. Except for the three-section control mode, the monitoring module is also adopted to monitor and display the running state of each device, and when abnormal conditions are detected, the monitoring module is used for displaying the running state so that the working personnel can know the state of the device and conduct troubleshooting.

The embodiment of the utility model provides a realize filtering and then reach waste water purification's purpose through setting up filter equipment the precipitation water in the aqua storage tank V7 to realize the backwashing operation to filter equipment through setting up backwashing pump 10, guarantee this clean system's purifying effect in a period, can promote filter equipment's life greatly through backwashing pump 10's setting.

The foregoing is only a preferred embodiment of the invention and the technical principles applied thereto. The present invention is not limited to the specific embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in more detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
