Abstract

The invention discloses a stably-operating continuous flow micro electrolytic reaction system. The system comprises a feed inlet, a discharge outlet and a deslagging hole and consists of a plurality of micro electrolytic reaction units which are connected in series, wherein each micro electrolytic reaction unit is provided with a packing layer; one side of the packing layer is provided with a packing replacement hole; a porous sieve plate is arranged below the packing layer; and an aeration back-flushing pipe is arranged below the porous sieve plate. For a micro electrolytic material used in the packing layer, the porosity and the specific surface area of the material are improved and the effect of removing pollutants in waste water by the micro electrolytic material is improved by using the effect of pore forming of NH3 generated by NH4Cl at a high temperature. Due to the designs of grading packing and aeration, the whole reaction system can effectively prevent the packing from being passivated and hardened, promote the waste water to contact the packing, improve treatment efficiency and effectively prevent bottom packing from being compacted and agglomerated due to overhigh micro electrolytic towers. Each stage of packing layer can be independently replaced, so that the simplicity and convenience of the operation and the maintenance of the whole reaction system are ensured.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a micro-electrolysis reaction system for waste water treatment. Background technique [0002] Due to the characteristics of high pollutant concentration, high toxicity, and poor biodegradability, industrial wastewater poses a serious threat to the ecological environment. Among them, micro-electrolysis technology has become an important industrial wastewater pollution control technology due to its good treatment effect, simple raw materials, and extensive sources. . [0003] Micro-electrolysis technology is also known as internal electrolysis method, iron-carbon method, corrosion battery method, iron filings filtration method, and zero-valent iron method. Easy to finalize and industrialize and other advantages. This technology began in the 1970s, and initially attracted widespread attention in the United States, Japan and other countries. In recent years, there have been more and mor...
