5. The water treatment method comprises the following steps:

a water treatment method, set up the filter element in the container, the filter element is driven by the lifting gearing; the method comprises the following steps: step 1: liquid feeding and dosing; the controller starts the electric control lifting driving mechanism to lift the filter element, controls the water inlet valve and starts the dosing mechanism to enable water to be treated and a medicament to enter the container, and the water to be treated is ejected from the water inlet pipe to wash the outer wall of the filter element, so that the self-cleaning of the filter element is realized; stopping rotation of the filter element after the filter element rises to a preset position (such as an upper limit position); the discharge pipe is closed in the liquid inlet process to prevent the liquid in the container from flowing out; for adding chemicals, a purifying chemical (such as a flocculating agent, preferably, a chemical and water are simultaneously added into a container) is added at the same time of water inlet, or the purifying chemical is added after the water is added into the container; or adding medicine first and then feeding water; as long as the medicine and the water can be fully mixed and reacted; a dosing mechanism provided in the container for dosing the water treatment agent into the container; the drug is administered by the administration means, and the drug is administered simultaneously when water is added, and the drug is preferably added through a separate tube, and preferably a solution with the drug is administered. Controlling the liquid medicine to enter or stop entering through a valve; or directly into a solid or powdered medicament, not shown. And 2, step: a reaction step; stopping feeding liquid after the liquid in the container reaches a certain set liquid level, and waiting for preset time to enable the medicament in the solution to fully act; and 3, step 3: pumping water; the controller drives the filter element to descend through the electric control lifting driving mechanism, after the filter element descends to a preset height, the lower end of the water outlet pipe can be ensured to contact with the liquid level, the water suction pump is started, and the water which is treated in the filter element is pumped through the water suction pipe; and 4, step 4: a step of discharging waste materials; after the water in the filter element is pumped out, the controller opens a discharge valve on a discharge pipe, so that sediment at the bottom in the container is discharged (or sucked out); for discharged fertilizer, the waste can be further dehydrated, such as treatment by a spiral shell stacking machine, a plate filter and other equipment; after the precipitate is discharged, the discharge pipe is closed again; and (5) ending the step, or returning to the step 1 and starting the water treatment process of the next period. The filter element is a rotary filter element and is driven by a motor through a transmission mechanism; the controller controls the rotation of the filter element through the motor and the transmission mechanism; when the filter element rises, the controller starts the motor to drive the filter element to rotate, and the filter element stops rotating after rising to a preset position (such as an upper limit position). Through the time of setting row's waste material, the guarantee precipitate can fully be discharged, perhaps detects the weight of the precipitate of container bottom through weighing sensor and is less than the default, and the guarantee precipitate can fully be discharged. The filter element is located at the lowest position, the liquid level is lower than the preset liquid level, or the flow of the water pipe is detected to be lower than the preset value through the flow meter arranged at the water outlet pipe, and the fact that water in the filter element is drained is indicated. And a relay protection control circuit is adopted to realize circulating water treatment control. A control circuit based on the MCU is adopted to realize the circulating water treatment control; the MCU is a singlechip, a PLC, an ARM processor or a DSP.

A plurality of lifting filter elements and liquid discharge devices can be arranged in one container; and synchronously controlling the plurality of lifting filter elements and the liquid drainage device. The controller monitors the liquid level in the container through the liquid level detection module. The liquid level detection module adopts a liquid level sensor or converts the liquid level into liquid level by adopting other sensors; if a flowmeter at the position of the water inlet pipe is adopted, the liquid level can be converted through the flow and the cross-sectional area of the container, and the liquid level can also be converted through hydraulic data acquired by a pressure sensor, because the pressure at the bottom of the liquid is in direct proportion to the liquid level. The inlet tube is annular feed liquor pipe, is equipped with a plurality of apopores on the pipe wall of feed liquor pipe. The bottom of filter core is equipped with the anti-water collector of magnetic levitation, and the anti-water collector of magnetic levitation is located the outside of filter core. When water exists, the magnetic levitation reverse water collector seals a pipeline of the magnetic levitation reverse water collector under the action of buoyancy, and when no water exists, a channel is opened, and impurities are discharged from a pipe opening.

And sixthly, applying and controlling the system based on MCU control:
