Iron Carbon Micro Electrolytic Tank for Water Treatment

  The utility model belongs to the field of waste water treatment, in particular to an iron carbon microelectrolysis device. The iron carbon microelectrolysis device comprises a tank body, an inner cylinder, a circulating pump, a backwashing jet device and a backwashing pump. The lower end of the inner cylinder is installed in the tank body through a polytetrafluoroethylene support. A backwashing baffle plate is disposed on the upper end of the inner cylinder. Packing materials are filled in the tank body. A backflow groove is disposed in the tank body and located above the upper end of the inner cylinder. The backflow groove is provided with a water outlet which is respectively connected with an input end of the circulating pump and an input end of the backwashing pump through pipelines.

An overflow water outlet is disposed on sidewall of the tank body above the backflow groove. An output end of the circulating pump is connected with the interior of the inner cylinder.

A pipeline is disposed inside the inner cylinder and is provided with an air inlet for access of air. An output end of the backwashing pump is connected with a backwashing mouth disposed on the tank body through a pipeline. The backwashing jet device is installed on the pipeline between the backwashing pump and the backwashing mouth. The pipeline provided with a backwashing air inlet is connected with the backwashing jet device. The iron carbon microelectrolysis device can enable degradative organic matters to break away from a packing layer, solves the problems that an iron carbon bed is easy to harden and passivate, and the like, and has a stable and continuous treatment effect.
