10. A method of controlling an integrated sewage sludge filtration system according to claim 7 comprising the steps of:
1) the control circuit system is powered on;
2) the user selects a mode;
the cleaning mode comprises the following steps:
firstly, closing the outlet valve, then closing the inlet valve, then opening the cleaning valve, and then opening the cleaning water pump; after the cleaning water pump is started, the liquid level meter detects the liquid level of the steel channel, and when the liquid level meter detects that the liquid level is at a low level, the cleaning water pump is kept started; when the liquid level meter detects that the liquid level is at a high level, the cleaning water pump is closed; after the cleaning water pump is closed, the cleaning drain valve is opened, and then the outlet valve is opened; then the grid host stops running; then closing the outlet valve until the sewage and sludge in the grid host are completely discharged, and finishing the cleaning;
the automatic mode comprises the following steps:
the method comprises the following steps of firstly opening an outlet valve, then opening an inlet valve, and then starting a liquid level meter, wherein the liquid level meter is used for detecting the liquid level of a steel channel, when the liquid level meter detects that the liquid level is at a low level, the outlet valve, the inlet valve and the liquid level meter are all kept in an open state, and when the liquid level meter detects that the liquid level is at a high level, a grid host is started; starting a back flush valve after a grid host is started, starting a back flush water pump, starting a squeezer, and stopping the grid host, the squeezer and the back flush water pump after sewage and sludge treatment; then closing the inlet valve; then closing the outlet valve after the sewage and sludge in the grid host are completely discharged, and ending the automatic mode;
the debugging mode comprises the following steps:
opening an outlet valve, then opening an inlet valve, then opening a back flushing valve, and then starting a back flushing water pump; then starting the grating host; starting the squeezer, and stopping the operation of the grid main machine, the squeezer and the backwashing water pump after debugging is finished; and then closing the inlet valve, and then closing the outlet valve again until the sewage and sludge in the grid host are completely discharged, and ending the debugging mode.
