Waste water lifting back flushing device
The invention relates to the technical field of pollution discharge devices, in particular to a waste water lifting back flushing device. The waste water lifting back flushing device comprises a water collecting tank and a pollution discharge device. The waste water lifting back flushing device is characterized in that a back flushing valve is arranged; two pollution discharge openings are formed in the lateral wall of the water collecting tank side by side; one pollution discharge opening is connected with a first pollution discharge device; the other pollution discharge opening is connected with a second pollution discharge device, and therefore the pollution discharge efficiency is better improved; the first pollution discharge device comprises a first pollution discharge pump, a first communication valve and a first pollution discharge tube; a first check valve and a first gate valve are arranged on the first pollution discharge tube; the second pollution discharge device comprises a second pollution discharge pump, a second communication valve and a second pollution discharge tube; a second check valve and a second gate valve are arranged on the second pollution discharge tube; the first pollution discharge tube and the second pollution discharge tube are communicated with the pollution discharge openings respectively; and one port of the back flushing valve is connected with the first pollution discharge tube, and the other port of the back flushing valve is connected with the second pollution discharge tube. The waste water lifting back flushing device has the beneficial effects of being simple in structure, convenient to operate, low in configuration cost, high in pollution discharge efficiency, long in service life and the like.
