Introduction: Electroplating wastewater contains dozens of inorganic and organic pollutants, among which inorganic pollutants are mainly copper, zinc, chromium, nickel, cadmium and other heavy metal ions, as well as acids, alkalis, and cyanides; organic pollutants are mainly carbon-containing organic compounds, Nitrogen-containing organics. Generally, electroplating wastewater is classified into cyanide-containing wastewater, chromium-containing wastewater, heavy metal (copper, zinc, nickel, etc.) wastewater, acid-base wastewater, and electroplating mixed wastewater according to the types of pollutants or types of heavy metal ions. The main treatment methods of electroplating wastewater are: alkaline chlorination method, chemical reduction method, chemical precipitation method, chemical method + membrane separation method; A / O, A2 / O, aerobic / membrane biological treatment, anoxic (or facultative) / Membrane biological treatment, anaerobic-hypoxia (or facultative) / membrane biological treatment technology; reverse osmosis advanced treatment technology, etc.

The A / O process is used to treat the effluent after the physical and chemical treatment of electroplating wastewater. As a result, the ammonia nitrogen in the effluent is much higher than the inlet water, but the COD removal effect is good. How can I improve the ammonia nitrogen removal rate?

In the treatment technology of refractory industrial wastewater, due to the low BOD / COD and complex components of the wastewater, it has a strong inhibitory effect on microbial activity, and direct biochemical has great difficulty. It must be strengthened pretreatment to change the original wastewater. Difficult to biochemical and molecular structure. For this reason, iron-carbon micro-electrolysis process and aerated iron-carbon micro-electrolysis process are often used for pretreatment of wastewater to improve the biodegradability of wastewater, to ensure the subsequent biological process, and to ensure that the effluent reaches the standard . At present, the iron-carbon micro-electrolysis process has a good application in high-concentration organic wastewater that is difficult to biochemical and difficult to degrade. The application industries include: chemical wastewater, circuit board wastewater, chemical fiber wastewater, dye wastewater, printing and dyeing wastewater, pharmaceutical wastewater, rubber additives, Coal chemical wastewater, phenolic resin, single crystal silicon chips, coking wastewater, penicillin wastewater, electroplating wastewater. The COD removal rate in wastewater is above 70 <h>% </ h>. For more information on ferrocarbon micro-electrolysis, please contact: 18765637009 QQ: 2635439305 Meng Fantao

The technical methods for electroplating wastewater treatment are great. At the same time, I would like to share with you: The "mineral method" used by Shenzhen Zeya Water Treatment Co., Ltd. can treat electroplating mixed wastewater without splitting treatment, but requires oily wastewater to be pretreated before being added to the mixed water body, or just All the sewage is mixed together, and a degreasing tank is designed in front of the dosing reaction system, which has reached no oil or little oil remaining in the sewage. Generally, two precipitation treatments are used. Through a large number of application cases, this process method can ensure that the treated water can be stably discharged and reduce costs. Shenzhen Zeya Water Treatment Co., Ltd. favors the use of hydrogen peroxide in the treatment of electroplating wastewater, which plays an important role in eliminating chemical nickel, anti-staining salt, ammonia nitrogen and other difficult-to-treat components. In order to ensure the best effect of the "mineral method" process, it is emphasized that aeration and stirring should be used and the aeration time must be ensured. Aeration pipes and water passing pipes must be reasonably installed.

Electric flocculation treatment equipment has many practical cases in the treatment of electroplating wastewater. The treatment effect is very good. It has the effects of redox, flocculation, and air flotation. It has a small footprint, high degree of automation, and less sludge than chemical treatment. Can be fully integrated into wastewater treatment technology.
