    Electroplating wastewater treatment equipment

    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.

    Treatment process:

    Electroplating sewage treatment equipment

    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.

    Equipment advantages:
    现场拼接组合,重量轻巧,易于运输,方便安装; 1. On-site splicing combination of industrial sewage treatment equipment , lightweight, easy to transport and convenient to install;
    2. It adopts FRP, carbon steel, stainless steel anti-corrosion structure, which has excellent characteristics such as corrosion resistance and aging resistance, and its service life is more than 60 years;
    3, placed below the ground, the ground above the equipment can be used for greening or other land, no need to build a house and heating and insulation. Electroplating sewage treatment equipment can also be placed on the ground surface to maximize system integration and reduce floor space;
    4. No pollution, no noise, no odor, reduce secondary pollution;
    5. It is not limited by the amount of sewage, and is flexible and can be used singly or in combination.
    6. The entire electroplating sewage treatment equipment treatment system is equipped with a PLC fully automatic electrical control system and equipment fault alarm system. The operation is safe and reliable. Generally, no special person is required to manage it. It is only necessary to maintain and maintain the equipment in a timely manner with low management costs.
