Problems solved by technology
This kind of treatment process cannot recover valuable substances such as precious metals in wastewater, and the water quality after treatment is unstable, and heavy metal substances are prone to exceed the standard. If the sludge containing heavy metals is not properly treated, it may cause secondary pollution.

The invention relates to a nickel-containing washing waste water recycling treatment system which comprises a waste water collecting system, an ultra-filter treatment system, a reverse osmosis treatment system, an evaporation concentration system and a recycling water supply system that are communicated with each other, wherein the waste water collecting system comprises a waste water collecting pump, a waste water collecting box and a liquid level control box which are communicated with each other; and the ultra-filter treatment system comprises an ultra-filter water supply pump, a bag-type filter, a precision filter, an ultra-filter membrane component, an ultra-filter backwashing pump and an ultra-filter water tank which are communicated with each other. The nickel-containing washing waste water recycling treatment system is used for treating nickel-containing electroplating rinsing water, needs no chemical agent, has good treatment effect, low operation cost and convenient operation, can continuously run for a long time, and meets the requirement of environmental protection clean electroplating. The system used for treating nickel-containing electroplating rinsing waste water not only saves the water resource, but also reduces the pollution, saves resource and protects the environment, thus bringing good economic benefit and social benefit.
Description
technical field [0001] The invention relates to the field of water treatment, in particular to a nickel-containing cleaning waste water recycling treatment system for recycling nickel-containing electroplating rinsing waste water to production and reducing waste water discharge. Background technique [0002] The electroplating cleaning water in the electroplating factory contains a lot of heavy metal ions. If it is discharged without treatment or the treatment is not up to standard, the wastewater will pollute the water source and the environment, which will not only endanger human health, but also cause the deterioration of the ecological environment. On the other hand, electroplating wastewater contains valuable substances such as precious metals or heavy metals. If recycled, it can not only reduce pollution, but also reduce production costs and save water resources. [0003] At present, the existing electroplating wastewater treatment devices generally add various chemica...
