Abstract

The invention relates to an automatic sludge-sucking device for a pre-sedimentation tank and a method of the device. The device includes the pre-sedimentation tank, one end of the pre-sedimentation tank is provided with a water inlet, and the other end is provided with a water outlet; the water inlet of the pre-sedimentation tank is sequentially provided with a first submerged overflow weir and aperforated tracery wall, and the water outlet of the pre-sedimentation tank is provided with a second submerged overflow weir; the bottom of the part, between the first submerged overflow weir and theperforated tracery wall, of the pre-sedimentation tank is provided with a dustpan bucket, and the interior of the dustpan bucket is connected with a water suction pipe passing through the dustpan bucket; the bottom of the part, facing the perforated tracery wall, of the second submerged overflow weir of the pre-sedimentation tank is provided with a sludge pit, the interior of the sludge pit is connected with a sludge discharge pipe passing through the sludge pit, and the other end of the sludge discharge pipe is connected to a sludge discharge ditch; and the bottom of the pre-sedimentation tank has a downwardly inclined slope from the perforated tracery wall to the second submerged overflow weir. Through the device provided by the invention, sludge sediment at a key sedimentation parte issucked while sludge is settled, so that the sludge discharging costs are saved, the sludge discharging efficiency is improved, and the sludge discharging effect is improved.

Description

technical field [0001] The invention relates to an automatic mud suction device for a pre-sedimentation tank and a method thereof, belonging to the technical field of sewage treatment. Background technique [0002] The pre-sedimentation tank is a sedimentation tank installed before coagulation and sedimentation treatment. The pre-sedimentation tank has a certain degree of homogenization of incoming water and can play a role in regulation. If the sediment is deposited in the pre-sedimentation tank, it will endanger the safe operation of the pumping station in severe cases. At present, the existing pre-sedimentation tank desilting technologies in my country mainly include perforated pipe desilting, multi-bucket desilting and mechanical desilting methods, but there are still certain technical bottlenecks in the sludge deposition in important parts, which are not easy to remove. Contents of the invention [0003] The patent of the present invention aims at the above-mentioned...
