Abstract

The invention discloses a coagulative precipitation tank, which comprises a tank body and a stirring device for stirring. A coagulant feeding device is arranged on a water inlet pipe of the tank body; a sludge discharge port is formed in the bottom part of the tank body. The coagulative precipitation tank is characterized in that an openable and closable clapboard is arranged in the tank body, and when the clapboard is closed, the tank body is divided into an upper part and a lower part; a liquid extracting device is arranged on the tank body, and comprises a liquid extracting pipe extending into the tank body and a telescopic support for installing the liquid extracting pipe; the support can drive the liquid extracting pipe to move up and down. According to the coagulative precipitation tank with the structure, a coagulation area and a precipitation area are integrated and separated through the clapboard, so that the space is greatly saved. In addition, the liquid extracting pipe for extracting clear liquid in the coagulative precipitation tank can be stretched by utilizing the support according to the height of a liquid level, so that the phenomena that the clear liquid cannot be extracted since the insertion depth of the liquid extracting pipe is insufficient, and a precipitate can be extracted since the insertion depth of the liquid extracting pipe is excessive are avoided.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a coagulation sedimentation tank. Background technique [0002] Coagulation sedimentation tank is a kind of sedimentation tank in wastewater treatment. The coagulation process is the most basic and extremely important process in the treatment of industrial water and domestic sewage. By adding some chemicals (commonly known as coagulants and coagulants) to the water, the particles that are difficult to settle in the water can be aggregated and formed. Colloids are formed, which then combine with impurities in the water to form larger flocs. The floc has a strong adsorption force, not only can absorb suspended solids, but also can absorb some bacteria and dissolved substances. Through adsorption, the flocs increase in volume and sink. Under the action of coagulant, the colloids and fine suspended matter in the wastewater are coagulated into flocs, and then separated and removed. Th...
