The invention discloses a non-wastewater environment-friendly hydraulic pressure-adapted water-purification control system which adopts the structure that a normally closed solenoid valve is arranged on a pipeline between a water-purification filter element and a circulation water tank; a first low voltage switch and a second low voltage switch are arranged on a pipeline between a water inflow interface and the water-purification filter element; a first high voltage switch and a second high voltage switch are connected onto an inlet/outlet pipeline of the circulation water tank; the first low voltage switch is connected in series onto a power supply circuit; the second low voltage switch is connected in parallel onto the power supply circuit; the popping pressure of the first low voltage switch is lower than that of the second low voltage switch; the first high voltage switch is connected in parallel onto the power supply circuit; the second high voltage switch is connected in series onto the second low voltage switch; the first high voltage switch and the second high voltage switch are connected in parallel to the normally closed solenoid valve; the popping pressure of the first high voltage switch is lower than that of the second high voltage switch. The water-purification control system can be protected effectively and reliably under different hydraulic pressure conditions.
