Abstract
The method that recycling sludge in Wire Rope Production reclaims metal, the invention belongs to environmental protection and resource regeneration project.Contain the economic requirement for being not reaching to industrial abstract under at a relatively high heavy metal lead (more than 2000ppm), usual state again in the sludge and spent acid of wire rope factory, wire rope enterprise can not be handled.Using sludge and spent acid hybrid reaction, the problem of sludge handles difficult with spent acid is then solved very well with the method for electrochemistry.
Description
Technical field
The present invention relates to the method that the recycling sludge in a kind of Wire Rope Production reclaims metal, belong to environment project
Field.
Background technology
Contain heavy metal (iron, zinc, lead etc.), oxide and salt, composition in sludge and spent acid that wire rope enterprise comes out
Considerably complicated, someone is handled using resin adsorption method, but because the too high enterprise of cost can not receive.Using alkali neutralisation, obtain
Mixing slag charge cause second of pollution, seek a kind of economically viable method to handle sludge and spent acid be for many years to make great efforts
Direction.
The content of the invention
For defect of the prior art, returned it is an object of the invention to provide the recycling sludge in a kind of Wire Rope Production
The method for receiving metal.
The present invention is achieved by the following technical solutions：
The present invention provides the method that the recycling sludge in a kind of Wire Rope Production reclaims metal, and it comprises the following steps：
After sludge in Wire Rope Production and spent acid are reacted, by separation of solid and liquid, obtain containing acid hydrochloride and contain
Phosphatic solid slag；
Using the acid hydrochloride that contains as electrolyte, iron, as negative electrode, is electrolysed as anode, aluminium, is made in electrolyte
Heavy metal ion is deposited on negative electrode；
The heavy metal simple substance on negative electrode and the electrolyte after electrolysis are collected respectively；
Vulcanized sodium is added in electrolyte to after by electrolysis, and adjusts pH value no more than 2, by separation of solid and liquid after reaction,
Obtain frerrous chloride and zinc sulphide.
Preferably, the pH value containing acid hydrochloride is 1.5~2.
Preferably, the weight ratio of the sludge and spent acid is 1:(2~8).
Preferably, the current density and voltage of the electrolysis are respectively 2000A/m2 and 0.6~1.6V.
The present invention general principle be：
1st, first by sludge and spent acid by a certain percentage hybrid reaction (because the composition of sludge and spent acid is relatively unstable, must
Need be per batch sampling and testing), by one-level separation of solid and liquid after reaction, gained solid is used as phosphoric acid iron material.
2nd, the liquid after separating, pH value mainly contains chlorination in 1.5~2 (retaining a small amount of acid number), this mixed solution
Salt (copper, lead, zinc, iron etc.).
3rd, by above-mentioned solution, in feeding electrolytic cell, Faradaic current is 2000A/m2, and voltage is 0.6~1.6V, passes through electricity
Relatively inactive metal ion in solution, solution, elemental metals (commercially available) are converted into negative electrode, and anode iron is in electricity
Solution, which is entered, under stream effect becomes frerrous chloride.
4th, also contain zinc chloride in solution of ferrous chloride, handled using vulcanized sodium and be changed into zinc sulphide, pH is below 2 for regulation,
By separation of solid and liquid after reaction, obtained frerrous chloride can be directly commercially available, and zinc sulphide can be commercially available by being further purified.
Compared with prior art, the present invention has following beneficial effect：
Handled by said process, sludge and the spent acid of wire rope factory are comprehensively utilized, both alleviated business processes and born
Load, and waste is become into the utilization of resources.
Embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that to the ordinary skill of this area
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection domain.
Embodiment 1
The present embodiment is related to the method that the recycling sludge in a kind of Wire Rope Production reclaims metal, and it includes following step
