B and treated waste water；
P6: sediment A and sediment B carry out plate compression, obtain high-content heavy metal sewage sludge, by high-content heavy metal sewage sludge into
Row heavy metal smelts recycling, that is, completes.
Further, flocculant is added in P3 step in level-one settling tank, and stirs flocculation treatment, settles.
Further, flocculant is added in P5 step in second level settling tank, and stirs flocculation treatment, settles.
Further, P6 step, heavy metal smelts recycling the following steps are included: smelting recycling heavy metal is adsorption recovery work
Skill, by heavy metal adsorption into adsorbent.
A small amount of water is added in the first step, the high concentration heavy metal sewage sludge that P6 step obtains, and adsorbent is added, stirs evenly, stirs
Mix process plantation concussion；Second step is centrifuged after the completion of absorption, and after centrifugation, stratification pours out supernatant, obtains absorption weight
The adsorbent of metal；Third step, the adsorbent acid adding elution after absorption, after elution, heavy metal is eluted in eluent；4th
Step, concentration, eluent is concentrated, heavy metal is obtained.
Further, the alkali of equivalent is added in the adsorbent after eluting in the third step, recycles adsorbent, adsorbent can be again
It puts into the first step and uses.
Further, the adsorbent is active carbon, sepiolite, polysaccharide resins, the one of which of diatomite.Adsorbent tool
There is adsorption capacity high, elution is easy, and quickly, is recycled often, adsorption efficiency is high, without secondary pollution.
The invention also discloses a kind of high-concentration industrial-water cleaning treatment systems, it is characterised in that: the system comprises
Level-one collecting-tank, level-one settling tank, second level collecting-tank, second level settling tank, the sheet frame device set gradually；The level-one collecting-tank connects
It meets PH and adjusts alkali tank, the second level collecting-tank connection PH adjusts sour tank.
Compared with prior art, the invention has the following advantages: high-concentration industrial-water purified treatment of the invention
Technique first carries out effective level-one to waste water and catchments, then adjusts PH, be modulated into alkalinity so that in waste water can be in intersexuality ring
The contamination precipitation of sediment is formed under border, then level-one settles, realize effective sedimentation, the effective impurity removed in waste water and
Then waste water is adjusted PH, is modulated into acidity by heavy metal, so that making that sediment can be formed under acidic environment in waste water
Contamination precipitation, then second level settles, and realizes effective sedimentation, and the effective impurity and heavy metal removed in waste water is adjusted respectively
The process then settled to PH realizes all kinds of impurity in effective removing waste water, realizes effective purification waste water, while to sedimentation
Heavy metal effectively recycles in object, realizes waste utilization.
