Electroplating sewage treatment equipment
Electroplating wastewater is various kinds of wastewater discharged during the electroplating production process. The main sources are: (1) cleaning water for plated parts; (2) waste electroplating solution; (3) other waste water, including flushing the workshop floor, washing electrode plate washing water, ventilation water condensate, and leakage or operation due to plating Various tank fluids and drainages of "running, running, dripping, leaking" caused by improper management; (4) equipment cooling water, the cooling water was not polluted except for temperature rise during use. (5) Metal surface treatment: Metal surface treatment includes cleaning before surface treatment, electroplating, passivation film protection, machining and coating coverage, etc., mainly electroplating.
Henan Zhonglan Water Treatment Engineering Co., Ltd. based on summing up the operating experience of electroplating wastewater treatment equipment at home and abroad, combining Henan Zhonglan Water Treatment Engineering Co., Ltd.'s own scientific research results and engineering practices, to design a complete set that can be buried Organic sewage treatment device, its equipment uses advanced technology and production technology at home and abroad in the late 1990s to produce electroplating sewage treatment equipment with carbon steel anticorrosion and stainless steel as the main raw materials. The purpose is to make the electroplating sewage treatment equipment and similar industrial organic sewage reach the discharge standard required by users after the equipment is treated.

① Removal of Cr6 + At present, chromium-containing electroplating wastewater mainly adopts a redox-precipitation method. The redox method refers to the use of strong oxidants or strong reducing agents to oxidize or reduce toxic substances in wastewater to non-toxic or low-toxic substances.
②. Removal of other metal ions. In addition to Cr6 + in the electroplating wastewater, which contains a large amount of metal ions such as Zn2 +, Cu2 +, Ni2 +, and Fe2 +, the method of aeration and oxidation under alkaline conditions can not only make PH The value reaches the discharge standard, and can effectively remove heavy metal ions in wastewater.
After two-stage precipitation treatment, the pH value and heavy metal ion indexes in the wastewater have passed, but the CODcr in the wastewater exceeds the standard due to the organic substances such as additives in the wastewater. (CODcr in the wastewater is partially produced by ferrous iron, and some is produced by organic matter). After two-stage precipitation, the CODcr value is about 200 mg / l, and the national standard is 100 mg / l. Therefore, after the two-stage precipitation pretreatment, the wastewater is treated by aerobic biochemical method to make it reach the national standard.
