Loaded down with trivial details, operating difficulties, and traditional chemical precipitation method effluent quality is bad, it is difficult to stable operation.Sulphide precipitation is to make
Heavy metal ion generates the metal sulfide precipitation of indissoluble with sulphion reaction, is isolated removal, the method and hydroxide
The sedimentation method are compared, and sediment weight is few, are easily dehydrated, beneficially the recovery of metal, but sulfide precipitation is relatively fine, it is difficult to sedimentation.
Reduction precipitation method is, with reducing agent, the heavy metal ion in heavy metal waste liquid is reduced to metal simple-substance or the relatively low gold of valence state
Belong to ion, first metal filtration is collected, in treatment fluid, add lime cream the most again so that the heavy metal ion of reduction-state is with hydrogen
The form precipitation of oxide is collected.The flocfloatation sedimentation method make the little colloidal solid in heavy metal waste liquid by adding flocculant
Bad stability, assembles and forms bulky grain colloidal substance, precipitate eventually through action of gravity.But independent these sides of use
, all there is the problem that effluent quality is the most up to standard in method.If by above-mentioned multiple chemical method integrated application to heavy metal liquid waste processing
In system, it is possible to significantly improve heavy metal liquid waste processing efficiency, improve effluent quality.
Owing to existing heavy metal liquid waste treating apparatus is to implement based on traditional chemical hydroxide precipitation method principle, because of
And this system footprint area is big, technological process is long, operation complexity, controls loaded down with trivial details, the problem that effluent quality is the most up to standard.If it is useless
Multiple chemical precipitation method can be integrated process heavy metal waste liquid by liquid processing device, and passes through modularity stored program controlled certainly
Dynamic operation process, can not only be reduced significantly the floor space of liquid waste treatment system, easy flow process, and shortening processes the time
Short, and heavy metal liquid waste processing effect can be improved, it is simple to operation, it is achieved automatic integratedization.
