The iron-carbon micro-electrolysis equipment independently developed by Wuchang Environmental Protection is also called a micro-electrolysis tower or a micro-electrolysis water treatment device. The micro-electrolysis equipment is a kind of sewage treatment and purification device that uses iron-carbon fillers for micro-electrolysis. After the iron-carbon filler is added, the principle of metal corrosion is used to form the original electric field to treat wastewater, which can be used to treat all kinds of difficult chemical wastewater.

Wuchang’s micro-electrolysis reactor can be widely used in coking wastewater, phenolic resin, rubber additives wastewater, water-based paint, pigments and dyes, electroplating circuit boards, medicine, pesticides and aquaculture and other difficult sewage fields, which can reduce COD and Improving the biodegradability of wastewater plays an important role. 

Micro-electrolysis technology is currently an ideal process for the treatment of high-concentration organic wastewater, also known as internal electrolysis. It uses the 1.2V potential difference generated by the micro-electrolysis material filled in the wastewater to electrolyze the wastewater in order to achieve the purpose of degrading organic pollutants without electricity. When the system is connected to water, countless micro-battery systems will be formed in the equipment, forming an electric field in its working space.

Treatment process of micro-electrolysis equipment:

The wastewater to be treated is sent to the reaction tank of the micro-electrolysis equipment after being uniformly adjusted in the conditioning tank. The micro-electrolysis material in the tank releases electrons. After the heavy metals or COD ions in the wastewater get the electrons, a chemical reaction occurs to generate elemental substances, which are deposited in the iron-carbon micro-electrolysis On the surface of the filler, ions in the water can be removed. As the reaction progresses, the iron in the filler will gradually fall off. In the process of falling off, it will be washed out of the filler surface as fine particles along with the copper and carbon particles deposited on the surface, and will enter the next processing unit with the water flow, and be separated and discharged by sedimentation. , This process does not require frequent manual cleaning of the micro-electrolysis packing cell.

Technical parameters of micro-electrolysis equipment:

Process characteristics of micro-electrolysis equipment:

1. It solves the problems of packing compaction, passivation, activation and replacement in the micro-electrolysis sewage treatment process, and has the advantage of continuous high-activity iron bed. Compared with the traditional iron-carbon filler, the loss is reduced by more than 60-65%, and the amount of sludge produced by the treatment is reduced by more than 60%.

2. The internal electrolysis cathode and anode and the catalyst form a framework alloy structure through high temperature, which will not be as prone to separation of cathode and anode as iron-carbon mixed assembly, which affects the primary battery reaction. According to the consumption volume, micro-electrolysis only needs to be added regularly without replacement.

3. Due to the dual effects of micro-electrolysis and catalyst, compared with the traditional iron-carbon filler for the treatment of wastewater with high concentration of organic matter, high toxicity, high chroma, and difficult to biochemically, the removal rate of COD in wastewater is increased by 15-20%. The removal rate of COD in wastewater is generally around 40-65%, and the chromaticity can be removed 65-95%, which improves the biodegradability of wastewater.

4. The electrolytic treatment method can achieve the effect of chemical precipitation and phosphorus removal. After the wastewater is treated by micro-electrolysis, the original ecological ferrous or iron ions will be formed in the water. There is no need to add iron salts and other coagulants, and it will not cause damage to the water. Sub-pollution.

5. For the high-concentration organic wastewater treatment projects that have been built but not up to the standard, using this technology as the pretreatment of the wastewater from the built projects can ensure the stable discharge of the wastewater after treatment, and it can also separate the part of the high-concentration wastewater in the production wastewater. Lead out for micro-electrolysis treatment.
