A one-way locking device is combined and arranged on the inner side of the cover wall; When the cover is buckled on the clamping disc, the cover edge abuts against the lower edge of the clamping disc, the inclined table surface of the wedge-shaped clamping table is correspondingly attached to the inclined table surface of the wedge-shaped clamping table, and the inclined table surface of the wedge-shaped clamping table is attached to the inclined table surface of the wedge-shaped clamping table more and more tightly along with the rotation of the cover, so that the pressure of the compression ring on the sealing gasket is enhanced, and the sealing gasket can seal the filter element in the cylinder; When the sealing cover rotates to a proper position in the forward direction, the one-way locking device locks the one-way ratchet to lock and position the sealing cover in time, so that the sealing cover keeps the pressure on the pressing ring and the pressing ring keeps the pressure on the sealing gasket; the unidirectional locking device comprises unidirectional elastic ratchets, a sliding top bolt, a unidirectional locking rotating shaft and a bidirectional unlocking rotating shaft; The one-way locking rotating shaft drives the sliding top bolt to a locking position so that the sliding top bolt abuts against the one-way elastic ratchet teeth and the one-way elastic ratchet teeth cannot deflect towards the sliding top bolt, and therefore the one-way elastic ratchet teeth are in an open state and are blocked against the one-way ratchet teeth; the bidirectional unlocking rotating shaft rotates positively to drive the sliding top bolt from the locking position to the unlocking position, and rotates reversely to drive the unidirectional elastic ratchet to deflect towards the sliding top bolt, so that the unidirectional elastic ratchet is in a retraction state and is separated from the unidirectional ratchet; The unidirectional elastic ratchet comprises a ratchet, an elastic arm and a clamping arm, wherein the ratchet is used for clamping the unidirectional ratchet, the clamping arm is provided with a clamping protrusion, and the ratchet and the clamping arm are respectively positioned at two ends of the elastic arm and extend towards the same side, so that the ratchet and the clamping arm are limited between the clamping disc and the cover wall and keep outward tension; The sliding top bolt is provided with a locking positioning groove and an unlocking positioning groove, when the sliding top bolt is in a locking position state, the clamping and resisting protrusion is clamped into the locking positioning groove, and when the sliding top bolt is in an unlocking position state, the clamping and resisting protrusion is clamped into the unlocking positioning groove.
2. The small household grey water treatment apparatus of claim 1, further comprising a filter screen disposed at a front end of the grey water precipitation unit.
3. The small household grey water treatment apparatus of claim 1, wherein the driving apparatus comprises a driving motor and a transmission chain driven by the driving motor to move up and down; the ash containing disc is clamped on the transmission chain.
