Description
Technical field
It is more particularly to a kind of to use industrial nickel-plating waste water after nickel is handled the present invention relates to a kind of chemical fertilizer and preparation method thereof
The water soluble fertilizer and preparation method thereof for preparing of waste liquid.
Background technology
Phosphorus is one of nutrient necessary to plant growth, phosphorus can promote plant as a kind of non-renewable resources
It is metabolized and grows, life is played an important role.But when phosphorus concentration is too high in water, body eutrophication can be caused, and then
Water pollution is caused, it is therefore proposed that the recycling of phosphorus-containing wastewater, phosphorus decomposing crisis of resource of easing up preventing and treating body eutrophication has
Significance.
At present, while bringing huge economy and social effect with the development of chemical plating nickel technology, unavoidably
Bring problem of environmental pollution.In chemical nickle-plating wastewater in addition to the heavy metal nickel containing high concentration, also containing substantial amounts of phosphoric acid
Salt and organic matter.Most enterprises, using lime neutralisation dephosphorization, make PO to pursue low-cost processes chemical nickle-plating wastewater4 3-、
HPO4 2-Separation of solid and liquid is carried out for the phosphate of indissoluble with calcium binding, the method effectively removes PO in decontaminated water4 3-With
HPO4 2-, but phosphorus is discharged with sludge, is not only caused environment pollution, and also results in phosphor resource loss.
China's agricultural production has huge demand to phosphatic manure, and mother of the chemical nickle-plating wastewater after being reclaimed by nickel
Liquid, it also contains substantial amounts of phosphate, organic matter and micro nickel, is the basic resource of good water soluble fertilizer.

In the method for the present invention, the compound of the Nitrogen element is urea, and the compound containing calcium constituent is calcium phosphate, is contained
The compound of magnesium elements is magnesium dihydrogen phosphate, and the compound containing potassium element is potassium nitrate.
The mother liquor that waste liquid of the chemical nickle-plating wastewater after nickel is handled is used to prepare agricultural fertilizer by the present invention, both reduces waste liquid
Discharge, turns waste into wealth again, and so as to realize effective utilization to resource, the present invention is to follow strictly the reality of Circular Economy
Example, it is a kind of with the efficient utilization of resource and to be recycling as the technical scheme of core.
On the basis of the present invention contains micro nickel element, P elements and organic matter in the mother liquor, appropriate addition contains
Nitrogen, potassium, calcium and magnesium elements compound in it is one or more form there is growth promotion to crops, improve percentage of seedgermination and
Strengthen the fertilizer of resistance against diseases.
Present invention process is simple, treating capacity is big, cost is low, and raw material easily obtains.The water soluble fertilizer has a wide range of application, and is applicable
In various crop, it is easy to promote the use of, it provides a kind of new approaches for industrial wastewater is recycled.
Embodiment
The present invention is the raw material based on the industrial wastewater by handling and can reach discharge standard, prepares agricultural fertilizer,
Its effectively utilize the industrial wastewater in balance the trace element that crops (including plant) can be had a positive effect, as nickel, phosphorus,
Potassium etc., greatly reduce the discharge of industrial wastewater, make full use of available resources, so as to be contributed for recycling for resource.
The water soluble fertilizer of the present invention is a kind of concentrate of the moderate-element type fertilizer of a great number of elements, and it is with chemical plating
Stoste (mother liquor for also known as preparing fertilizer) based on waste liquid of the nickel waste water after nickel is handled, add the element system of correlation again afterwards
.The concentrate is made up of the component of following mass fraction meter：
