Packing material is activated carbon, and the packing material of the 3rd filtering adsorption column is to press 0.5-2 by graphene and nanometer iron powder：1 quality
Than the material being obtained by mixing；
Two outlets are at least offered on the discharge supervision pond, one of outlet connects with the first filtering adsorption column pipeline
It is logical.
In above-mentioned technical proposal, pretreatment pool is used to store waste water and carries out acidity adjustment to waste water, typically by waste water
PH value be adjusted between 3-5.
In above-mentioned technical proposal, in order to enable the waste water in pretreatment pool more to smoothly enter in the first filtering adsorption column
Filtering absorption is carried out, a power dress is preferably set gradually on the communication path of pretreatment pool and the first filtering adsorption column
Put, and a flowmeter.In this application, the power set are preferably peristaltic pump or jet stream jet pump.
In above-mentioned technical proposal, the packing material of the 3rd filtering adsorption column preferably presses 1 by graphene and nanometer iron powder：1
The material that is obtained by mixing of mass ratio.It so can preferably adsorb the heavy metal ion in waste water.
In above-mentioned technical proposal, each packing material filtered in adsorption column needs to carry out routine after a certain time of operation
Cleaning or regeneration treatment or more conversion materials, specifically, as quartz sand needs to refill use, absorbent charcoal material after being cleaned
Then need to be used again after carrying out existing conventional regeneration treatment, and graphene and nanometer iron powder then need replacing new material
Material.
Compared with prior art, it is the characteristics of the utility model：By being set between pretreatment pool and discharge supervision pond
Three-stage filtration adsorption column is put, wherein the first filtering adsorption column reaches the solid suspension effectively removed in waste water and carries out initial clear
The purpose of water purification body；Second filtering adsorption column persistently cleans, adsorb heavy metal ion and adsorbate in waste water, with mitigation to rear
The burden of continuous 3rd filtering adsorption column；And the 3rd filtering adsorption column to residual heavy metal ion further reduce and be co-precipitated
Absorption, is substantially improved removal efficiency, three-stage filtration adsorption column collective effect is effective by the heavy metal ion in waste water to realize
The purpose of removal.
