Mechanical stirring and clarifying pond

Abstract

The invention discloses a mechanical stirring and clarifying pond. The mechanical stirring and clarifying pond comprises a clarifying pond, wherein a residue collecting hole is formed in the bottom ofthe inner wall of the clarifying pond; a residue collecting pipe is fixedly connected to the inner part of the residue collecting hole; a valve is fixedly connected to the outer wall of the residue collecting pipe; a suction pump is fixedly connected to the bottom of the residue collecting pipe; a mud discharging pipe is fixedly connected to the top of the suction pump; supporting rods are fixedly connected to the bottom of the inner wall of the clarifying pond; and a motor tank is fixedly connected to the tops of the supporting rods. According to the mechanical stirring and clarifying pond disclosed by the invention, a scraping plate is arranged at the bottoms of the stirring rods, so that water currents can be effectively stirred, and mud and residues are promoted to circulate; solid impurities in water and the formed mud and the formed residues are in contact to flocculate to be separated and precipitated; and when the water currents are clarified and upper-layer clean water currents are drained through a through groove, the scraping plate is used for scraping sludge precipitated at the bottom of the inner wall of the clarifying pond, and the sludge is collected into the residue collecting hole, so that the cleaning of the clarifying pond is simple and convenient, and human resources and financial resources are saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a mechanically stirred clarifier. Background technique [0002] Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and has complex components. It is not only difficult to purify in water, but also difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of pollutants emitted by industry. The pollutants contained in industrial wastewater vary widely depending on the type of factory. Even if it is the same kind of factory, the production process is different, and the quality and quantity of the pollutants contained in it are not the same. In addition to the pollution caused by the direct injection of industrial wastewater into the water body, solid ...
