Background technology
Arsenic (As) and compound thereof belong to extremely toxic substance.Arsenic in arsenic sulfide slag is with armorphous sulfide (As2S2Or As2S3Or As2S5Presented in), and easily dissolution under acidity or alkaline environment, water and soil are caused severe contamination.
Process currently for arsenic sulfide slag mainly carries out recycling and solidification and stabilization processes.Its resource is mainly and arsenic carries out leaching matter containing arsenics such as producing arsenic oxide arsenoxide.Due to arsenic and the strong toxicity of compound thereof, marketing management is difficult, usage amount is relatively fewer and purity requirement is high, so most arsenic sulfide slag is in the state of storing up, it would be highly desirable to process.
The advantages such as treatment agent is cheap to be easy to get owing to it has in stabilisation/solidification, and processing cost is relatively low, and disposal amount is big become the most common processing method of arsenic-containing waste residue.In terms of the solidification and stabilization of existing arsenic sulfide slag, have with heavy metal sewage sludge, calcium hydroxide as stabilization agent, with yellow sand and cement as firming agent, the treatment of wastes with processes of wastes against one another, it is achieved the stabilisation/solidification of arsenic sulfide slag, but, its increase-volume is big, indirectly adds the process cost of disposal of arsenic sulfide slag.Also have in arsenic sulfide slag, add the inorganic flocculating agent liquid such as polyaluminium sulfate, bodied ferric sulfate, polysilicon acid flocculant, add iron powder, magnesium oxide pressed powder adsorbent；It is eventually adding asbestos wool stirring.This technological process is simple, workable, but its mixing time is longer, and energy consumption is higher.
Summary of the invention
A kind of method that it is an object of the invention to provide arsenic sulfide slag harmless treatment, the method can effective stabilisation/solidification arsenic sulfide slag.
The technical scheme is that and be achieved in that: a kind of method of arsenic sulfide slag harmless treatment, comprise the following steps: at ambient temperature, in arsenic sulfide slag, add water, mixing, obtain mixture I, add sodium sulfide reaction, be 8～12 to pH value, obtain mixture II, it is subsequently adding oxidant and carries out oxidation reaction, obtain mixture III, add iron salt or aluminium salt reaction subsequently, obtain mixture IV, add cement.
In the present invention, the sodium sulfide etc. that addition water can make back add better contacts with arsenic sulfide slag, fully reacts；Add sodium sulfide reaction to be to generate new matter containing arsenic；Add iron salt or aluminium salt reaction is to make newly-generated matter containing arsenic react precipitations such as being converted into Fe/Al-As-S/O further；Adding cement is for solidifying, and conveniently carries out filling or stacking process.
As preferably, described arsenic sulfide slag is 10～100:10～50 with the mass ratio of water；The time of described mixing is 1～10 minute.
As preferably, the time of described sodium sulfide reaction is 30～60 minutes.
As preferably, described oxidant is selected from the one in hydrogen peroxide or sodium hypochlorite.
As preferably, the time of described oxidation reaction is 30～60 minutes.
As preferably, described mixture II is 1:1～30 with the mass ratio of oxidant.
As preferably, described iron salt is selected from the one in bodied ferric sulfate or ferrous sulfate, or their arbitrary proportion mixture；Described aluminium salt is selected from aluminium polychlorid.
As preferably, described mixture III is 1:0.1～5 with the mass ratio of iron salt or aluminium salt；The time of described addition iron salt or aluminium salt reaction is 10～45 minutes.
As preferably, described mixture IV is 1:1～20 with the mass ratio of cement.
As preferably, after the step of described addition cement, also include maintenance；The time of described maintenance is 3～15 days.
The beneficial effects of the present invention is:
Utilize arsenic sulfide and sodium sulfide, iron salt, the complex reaction that aluminium salt etc. is occurred, generate Fe/Al-As-S/O system arsenic firming body, it is achieved the harmless treatment of arsenic.Can effectively reduce the arsenic leaching concentration of arsenic sulfide slag, arsenic sulfide slag after treatment meets danger wastes landfill requirement, and technological process is simple, increase-volume is little, workable, mixing time is short, energy consumption is low.
