Wash waste water filter device

A wash waste water filter device comprises a filter tank, and the filter tank is provided with an upper end cover, a waste water inlet, a first filter chamber, a second filter chamber, a third filter chamber and a waste water outlet. The first filter chamber is jointly defined by a vertical separation board arranged between the front wall and the back wall of the filter tank, a first-stage filter net arranged between the lower portion of the vertical separation board and the right wall of the filter tank, the front wall and the back wall. An include angle is formed between the first-stage filter net and the horizontal plane, and a first dreg outlet is formed in the lowermost portion of the junction of the first-stage filter net and the right wall of the filter tank. A second dreg outlet is formed in the bottom of the second filter chamber. A timing dreg discharge valve is arranged at the second dreg outlet and is controlled by a control device, and a timing component is arranged in the control device and can control a traction control line to open the timing dreg discharge valve at regular time to remove dreg at the bottom of the second filter chamber at regular time. The wash waste water filter device can effectively filter wash waste water in a water room for public use, and then the water can be used for flushing a toilet or for other purposes.
