Embodiment Construction

[0011] Such as figure 1 As shown, a micro-electrolytic packing, the packing has a cylindrical structure, and is uniformly arranged on the outer wall of the packing so that the end surface of the packing presents a gear-shaped groove 1 . The groove 1 is parallel to the axis of the packing. The height of the packing is 25-28mm, and the overall diameter is 35-40mm.

Abstract

The invention relates to the technical field of micro-electrolysis filling material used in wastewater treatment. The filling material has a cylinder structure, and the lateral wall of the filling material is uniformly provided with grooves which can make the end face of the filling material be in a gear shape. The regulated structure of the filling material keeps an adequate gap between the cumulated filling materials, thereby ensuring the complete catalyzed reaction of the filling materials and the water and simultaneously reducing the flow resistance of the water, the physical form of the filling material increases the specific surface area of the filling material as far as possible, and therefore, the micro-electrolysis effect is obvious, and the bio-film can be applied easily.

Description

technical field [0001] The invention relates to the technical field of micro-electrolytic fillers for sewage treatment. Background technique [0002] The existing iron-carbon bed micro-electrolysis tower filler is fine-grained iron filings, which is ideal for treating high COD wastewater, especially acidic organic wastewater. It is also a conventional technology commonly used by almost all environmental protection companies, but this kind of filler is used in After two months of operation in the micro-electrolysis tower, the effect will drop sharply, which is mainly caused by the passivation of the iron-carbon bed, hardening and other reasons. At the same time, due to the large amount of iron sludge, the micro-electrolysis tower will be silted up, and backwashing can slow down the iron sludge. Blockage, alone cannot solve the problem of the decline in sewage treatment effect, which can only be replaced with new fillers frequently. However, the workload of replacing the pack...
