Polishing machine sewage treatment device

Abstract

The invention discloses a polishing machine sewage treatment device. The device comprises a pH value adjustment chamber, a flocculation chamber, a metal trap chamber, a centrifuge, a biological oxidation chamber and a circulating water tank that are connected in order. The pH value adjustment chamber is internally provided with a pH sensor, the flocculation chamber is internally equipped with a stirring apparatus, the stirring apparatus consists of a stirring blade, a stirring shaft and a stirring motor that are connected in order, the stirring blade includes a shell and a hollow cavity, outflow holes are uniformly distributed on the shell, the follow cavity is used for filling of a liquid flocculant, the flocculation chamber and the metal trap chamber are provided with a filter layer, the metal trap chamber comprises a nozzle arranged on the upper part of the metal trap chamber and a water outlet arranged on the lower part of the metal trap chamber, the nozzle jets a metal trapping agent into the metal trap chamber, and the water outlet is connected to a water inlet of the centrifuge. The polishing machine sewage treatment device provided by the invention achieves real-time and continuous oxidation treatment on sewage through the oxidation effect of the biological oxidation chamber, and avoids the problem of uncontinuous sewage treatment in the existing technology of using a strong oxidant to remove COD from sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment of a finishing machine, in particular to a sewage treatment device for a finishing machine. Background technique [0002] With the development of the global economy, the demand for steel products from all walks of life is increasing, and the quality requirements for steel products are also getting higher and higher. The precision processing requirements of mechanical parts made of steel and steel casting products have also driven the development of the finishing industry. Finishing, also known as finishing, is a new technology for surface finishing of workpieces. It puts a certain proportion of workpieces, abrasives and additives in the container of the finishing machine, and relies on the periodic vibration of the container to make the workpieces and abrasives move and grind each other, so as to remove burrs, chamfers, burrs, polish, The purpose of precision grinding and processing wor...
