4) after chelating trapping in 10 days, gather in the crops tapetum fibrosum, desurfacing pasture and water impurity, tapetum fibrosum is put into activating tank and lives
Change, recycled fiber blanket, tapetum fibrosum can activation utilization more than 5 times, after activating tank heavy metal concentration reaches to a certain degree, carry out weight
Metal recovery or disposal.
Mass can be applied above-mentioned tapetum fibrosum in current water (such as: river) by the present embodiment, neither affects water body flow,
River heavy metal pollution can be realized again and remove purpose.
Embodiment 2:
1) particulat cellulosic xanthates is loaded in strip water penetration cloth bag 5, cloth bag 5 is sutured on canvas,
I.e. make heavy metal chelating functional layer, thickness 20mm；
2) MR adhesive homalographic is used to glue polystyrene foam thick with 50mm for above-mentioned heavy metal chelating functional layer
Close, i.e. make heavy metal chelating trapping tapetum fibrosum, such as Fig. 2；
3) being placed in the electroplating wastewater pond of adjusted pH to more than 6 by above-mentioned tapetum fibrosum, period tapetum fibrosum will float on water
Pond both sides, agitation water body is beneficial to the chelating trapping of heavy metal；
4) after chelating traps 2 hours, take out tapetum fibrosum, pour particulat cellulosic xanthates into activation recovery pond, return
Receive particulat cellulosic xanthates, when recovery pond heavy metal concentration reaches to a certain degree can reclaim valuable metal unit further
Element.
The present embodiment can effectively remove heavy metal in electroplating wastewater concentration, and reclaims valuable metal element.
It is finally noted that, the purpose publicizing and implementing mode is that help is further appreciated by this utility model, but
It will be appreciated by those skilled in the art that: without departing from this utility model and appended spirit and scope by the claims, respectively
It is all possible for planting substitutions and modifications.Therefore, this utility model should not be limited to embodiment disclosure of that, this utility model
Claimed scope defines in the range of standard with claims.
