The utility model discloses a
water supply and drainage
sewage clarification device which comprises an inner cylinder and an outer cylinder, a
sedimentation assembly is installed at the bottom of the inner cylinder and the bottom of the outer cylinder, the
sedimentation assembly comprises a first conical hopper and a second conical hopper, a deslagging
assembly is installed on the inner side of the first conical hopper and the inner side of the second conical hopper, and the deslagging assembly comprises a discharging valve and an inclined baffle. The
water supply and drainage
sewage clarification device comprises an inner
barrel and an outer
barrel, an inlet and outlet assembly is installed on the inner
barrel and the outer barrel, the inlet and outlet assembly comprises an inlet
pipe and an outlet
pipe, valve assemblies are installed on the inner barrel and the outlet
pipe, and each valve assembly comprises a valve and an
electromagnetic valve. The situation that solids with low
settling speed cannot be effectively settled due to interference of
water flow is avoided, the
solid-liquid separation effect is guaranteed, the situation that
sewage generates large
impact force in the outer barrel is avoided, settled
sludge is further prevented from being mixed with the
water flow, the inclined baffle is used for forming isolation at the bottoms of the outer barrel and the inner barrel, and the separation efficiency is improved. The device is suitable for sewage clarification operation of
water supply and drainage projects.
