Industrial sewage treatment system

Abstract

The invention relates to the technical field of sewage treatment, and in particular, relates to an industrial sewage treatment system including an outer barrel and an inner barrel; a water injection pipe, a drainage pipe and an interlayer are arranged between the outer barrel and the inner barrel; a sliding rack is slidingly connected on the inner wall of the outer barrel, and a reset piece is connected between the sliding rack and the outer barrel; a stirring rod is rotationally connected in the inner barrel and is provided with a first stirring bevel gear, and the bottom of the inner barrelis provided with a water leakage net for supporting flocs; the interlayer is internally provided with a transverse shaft rod, a vertical shaft rod, a rotating rod and a water pumping mechanism for pumping water in the interlayer into the inner barrel; the transverse shaft rod is provided with an active gear, a transverse bevel gear and a water wheel rotating by adopting water flowing out of the water leakage net; the vertical shaft rod is provided with a vertical bevel gear, a second stirring bevel gear and a first rotating bevel gear; the rotating rod is provided with a negative pressure blade and a second rotating bevel gear; the inner barrel is provided with a suction pipeline for sucking floating flocs, and the suction pipeline communicates with the negative pressure blade. The industrial sewage treatment system can automatically exclude the floating flocs.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an industrial sewage treatment system. Background technique [0002] According to the classification of sewage sources, common sewage includes domestic sewage, industrial sewage, agricultural sewage and medical sewage. Sewage treatment methods include physical treatment, chemical treatment and biological treatment. Among them, the chemical treatment method is a wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater or converts them into harmless substances through chemical reactions and mass transfer. In the chemical treatment method, the treatment units based on the chemical reaction produced by adding chemicals are: coagulation, neutralization, redox, etc. [0003] Compared with other physical and chemical methods, the coagulation-sedimentation process has the advantages of good effluent quality, stable and reliable pr...

Problems solved by technology

[0004] In the actual process of coagulation and sedimentation, when the coagulation process is over, most of the flocs will sink to the bottom of the sedimentation tank, but some of the flocs will often float up. The main reasons for this phenomenon are: The discharge of flocs is not timely, which leads to the overload of mud in the sedimentation tank; the gas produced by anaerobic microorganisms in the water, these gases are attached to the flocs and cause the flocs to float

And for the situation that the flocs float up, the method usually adopted in the prior art is to manually collect the floating flocs with a salvage net to get rid of the flocs on the water surface. This method needs to manually monitor the generation of the flocs, and collect less efficient
