Device for treating production sewage by iron ion flocculation activity

Abstract

The invention relates to the technical field of production sewage treatment. The invention further discloses a device for treating production sewage by iron ion flocculation activity. The device comprises a reaction box, a placement groove is fixedly connected into the reaction box, a decomposition shell is fixedly connected to the side, away from the reaction box, of the placement groove, a feeding pipe is fixedly connected to the top of the decomposition shell, a gear is movably connected to the top end of the feeding pipe, a spring rod is movably connected to the surface of the gear, and amagnetic ring is movably connected to the end, away from the gear, of the spring rod. The magnetic ring produces a pushed force in the direction far away from the decomposition shell under the actionof an electric field, if a chemical reaction in the decomposition shell cannot be performed when the surfaces of the scrap iron and the charcoal are passivated and hardened, a rear spring rod extrudesa buffer layer, the buffer layer pushes a main meshing wheel to rotate under clamping of a guide wheel, then extends to contact with the surfaces of the scrap iron and charcoal, and then scrapes offthe surfaces, contacting with sewage, of the scrap iron and charcoal, so that the effect of eliminating the raw material surface passivation and hardening phenomenon without replacing materials is achieved.

Description

technical field [0001] The invention relates to the technical field of production sewage treatment, in particular to equipment for treating production sewage by using iron ion flocculation activity. Background technique [0002] Production sewage refers to the total amount of wastewater discharged from all outlets of enterprises and institutions in the process of production and scientific research; the pollution of production wastewater is relatively light, and the pollution of production sewage is serious. For the treatment of production sewage, the existing technology adopts the use of sewage purifiers However, the water treated by this method contains chemical substances, which is not conducive to the regeneration of water resources. [0003] With the development of science and technology, a micro-electrolysis method has been developed to treat production sewage.

[0002] Production sewage refers to the total amount of wastewater discharged from all outlets of enterprises and institutions in the process of production and scientific research; the pollution of production wastewater is relatively light, and the pollution of production sewage is serious. For the treatment of production sewage, the existing technology adopts the use of sewage purifiers However, the water treated by this method contains chemical substances, which is not conducive to the regeneration of water resources

[0003] With the development of science and technology, a micro-electrolysis method has been developed to treat production sewage. This method uses the physical and chemical reactions between water and substances to remove harmful substances in sewage. However, in this method, the electrolytic cathode and anode involved in the reaction The raw materials are in direct physical contact. After a period of use, an isolation layer will appear on the surface, which will cause the electrolysis to fail and lose its effect; in addition, because this method involves chemical reactions, the surface of the raw materials will be degraded during the reaction with the substances in the sewage. Passivation and compaction, which in turn affects the treatment effect of sewage, so a kind of equipment that uses iron ion flocculation activity to treat production sewage came into being
