Description
Technical field
The invention belongs to field of environment protection, and in particular to the modification biological charcoal based on reed straw and answering in lead contamination
With.
Background technology
Lead is that one of relatively broad heavy metal is distributed in nature, is mainly derived from metal smelt, plating, electric power storage
The industrial products such as pond, dyestuff, construction material, gasoline.Lead is organism non-essential element, is not involved in the metabolic activity of organism,
It is easily accumulated in organism, is a kind of heavy metal pernicious.
At present, the method that lead is removed from waste water mainly has chemical precipitation method, electrochemical reducing, absorption method and reverse osmosis
Method etc..In comparison, absorption method has the advantages such as raw material sources are extensive, removal effect is good, operating cost is low, is processing water body weight
The main method of metallic pollution.Charcoal is the black puffy solid-state rich in carbon of a kind of indissoluble, stabilization, height aromatization
Substance has fine and close microcellular structure and huge specific surface area, and adsorption capacity is strong, energy Adsorption of Lead, chromium, mercury, cadmium, copper, zinc etc.
Heavy metal.Heavy metal production cost is low using charcoal absorption, ecological safety, pollution-free, can promote on a large scale, be a kind of emerging
, have development prospect technology.The absorption behavior of charcoal can influence heavy metal ion Transport And Transformation in the environment, life
The processes such as the control and reparation of state effect and contaminated environment medium, therefore, absorption of the research charcoal to heavy metal ion
Effect is one of subject that environmental worker extremely pays close attention in recent years.Reed is widely distributed in China, resourceful, is to prepare life
The desirable feedstock of object charcoal.Some research shows that, reed charcoal has higher adsorption effect to cupric and nickelous.
Although reed charcoal also has certain adsorption effect to divalent lead, there is the space further improved.
