Problems solved by technology

The drum-type micro-electrolysis water treatment method based on these devices has solved the problem of hardening and clogging of the iron-carbon fixed bed well, but with the increase of the drum-type micro-electrolysis reaction time, a large amount of Fe formed in the drum reactor 2+ , Fe 3+ On the one hand, these precipitates adhere to the surface of iron and carbon, which affects the efficiency of iron-carbon micro-electrolysis reaction, resulting in a decrease in treatment efficiency. On the other hand, the increase in sediment also reduces the effective volume of the reactor, and also will affect the processing effect

Description

technical field [0001] The invention relates to a device in the technical field of water treatment and a treatment method thereof, in particular to a drum-type micro-electrolysis reaction device and a water treatment method thereof. Background technique [0002] Over the years, my country has made great achievements in the treatment of urban domestic sewage and biodegradable industrial wastewater, and has made important contributions to my country's environmental protection. In recent years, with the rapid development of the chemical, pharmaceutical, and petrochemical industries, there are more and more organic wastewater with less water but high concentration, refractory degradation, and high salinity. This type of wastewater has become a new public hazard. Only a single biochemical treatment is used. It is simply impossible to meet the national emission requirements. For the treatment of such high-concentration refractory wastewater, pretreatment technology must be adopte...
