The primary source of zinc in metal processing wastewater is from electroplating or acid cleaning.The dragging fluid. Pollutants are transferred back to the washing water during the metal washing process. The acid washing process involves first soaking the metal (zinc or copper) in strong acid to remove surface oxides, followed by immersion in a solution containing strong chromic acid.Polishing agentThe wastewater undergoes brightening treatment. It contains a high concentration of hydrochloric acid and heavy metal ions such as zinc and copper, as well as organic brighteners, which are highly toxic. Some of it even contains highly toxic substances that are carcinogenic, teratogenic, and mutagenic, posing significant harm to humans.Integrated sewage treatment equipment utilizes biological treatment technology.浦膜Environmental Protection's specialized water treatment R&D team, based on the operational experience of domestic domestic sewage treatment equipment, designs and develops integrated sewage treatment systems according to the clients' water usage and quality requirements. The wastewater treatment equipment is a comprehensive package that includes...A unit for BOD5, COD, and NH3-N removal, featuring stable and reliable technical performance, excellent treatment effects, low investment costs, automated operation, easy maintenance, no floor space required, no need for building structures, and benefits like no heating or insulation. The integrated wastewater equipment is made of corrosion and oxidation-resistant materials, ensuring a longer service life and reduced operation costs. The unit can be installed underground, allowing for planting flowers and grass above ground without affecting the surrounding environment.

Process Flow
Raw waterGrille → Control Pool → Lift Pump → Bioreactor → Circulation Pump → Membrane Module → Disinfection Unit → Recycled Water Storage Tank → Recycled Water Utilization System
Process Description
Wastewater flows through a grille into the control pond, then is pumped into the bioreactor.PLC controllers operate the aeration devices to oxygenate the wastewater, which is then recycled and fed into the membrane separation unit. The wastewater from the bioreactor is returned to the control pool, where the membrane-separated water is chlorinated via a rapid mixing method (bleaching powder, chlorine tablets) before entering the water storage pond. The backwashing pump uses treated water from the rinse pool to backwash the membrane treatment equipment, with the backwashing wastewater returned to the regulating pool. The start and stop of the lift pump are controlled by the water level in the bioreactor. The filtration and backwashing operations of the membrane unit can be controlled automatically or manually. If the membrane unit requires chemical cleaning, close the water supply and wastewater recycling valves, open the chemical cleaning and chemical circulation valves, start the chemical circulation pump, and then perform the chemical cleaning.
Application Fields
Ideal for treating domestic wastewater in residential areas, office buildings, shopping malls, hotels, restaurants, government agencies, schools, factories, and similar industrial organic wastewater from sectors like textiles, beer production, papermaking, leather processing, food, and chemical industries.
