Granular active carbon circulating micro-electrolysis reactor

Abstract

The invention relates to a granular active carbon circulating micro-electrolysis reactor, comprising a micropore aeration pipe, a granular active carbon separating chamber, wherein the micropore aeration pipe is connected with a total aeration pipe and positioned at the bottom of the reactor; positive poles of a plurality of scrap iron plates are uniformly distributed on the upper middle of the reactor at equal intervals; a support beam I and a support beam II which are fixed on the inner lateral wall of the reactor and processed with corrosion resisting materials are provided with a fixed clamping groove I and a fixed clamping groove II, and the left end, the right end, the upper end and the lower end of the positive poles of the scrap iron plates are vertically fixed in the fixed clamping groove I and the fixed clamping groove II; waste water enters in the reactor through a water inlet pipe; micro-bubbles generated by the micropore aeration pipe provide rising power for granular active carbon so that the granular active carbon rises among the positive poles of the scrap iron plates so as to form a granular active carbon rising area; the gravity of the granular active carbon is reduced in a non-aeration area so as to realize the granular active carbon circulating in the reactor; and the water enters in the granular active carbon separating chamber through an overflow weir after being processed and is discharged by a water outflow pipe. The invention solves the problems of scrap iron hardening, waste water channeling, micro-electrolysis positive pole inactivating which is puzzled for a long time and the problem that redox sediments are attached to positive and negative poles.

Description

technical field [0001] The patent of the invention belongs to a sewage treatment device, and relates to a high-concentration refractory organic waste water treatment device, more precisely, to a granular activated carbon circulation micro-electrolysis reactor. Background technique [0002] The micro-electrolysis method, also known as the internal electrolysis method, uses iron and carbon in iron filings to form a primary battery to achieve the degradation of pollutants in water and achieve the purpose of "treating waste with waste". Micro-electrolysis is a new type of wastewater treatment technology developed with the application of redox reaction in wastewater treatment. Its working principle in the field of wastewater treatment can be summarized as: (a) redox reaction; (b ) galvanic cell reaction; (c) electrochemical attachment; (d) physical adsorption; (e) coagulation of iron; (f) precipitation of iron ions. Micro-electrolysis technology is based on the synergistic treat...
