Embodiment 1
[0033] The pretreated water is natural river water, and 20 kg of the fiber material is put into a reactor made of a PVC pipe with a diameter of 160 mm and a length of 1000 mm. The reactor is upright, the treated water flows freely from top to bottom, and the flow rate is stable at 0.61m 3 / h, under the condition of continuous operation for 20 days, the device's removal rate of heavy metals in natural river water reached 97%, the removal rate of organic pollutants reached 98%, and the killing rate of microorganisms reached 99.9%.
Embodiment 2
[0035] The pretreated water is ground water, and 20 kg of the fibrous material is put into a reactor made of a PVC pipe with a diameter of 160 mm and a length of 1000 mm. The reactor is upright, the treated water flows freely from top to bottom, and the flow rate is stable at 0.61m under the condition of continuous operation for 20 days 3 / h, the removal rate of heavy metals in groundwater by the device reaches 98%, the removal rate of organic pollutants reaches 99%, and the microbial killing rate reaches 99.9%.
Embodiment 3
[0037] The pretreated water is the outlet water of the municipal sewage treatment plant, and 20 kg of the fiber material is put into a reactor made of a PVC pipe with a diameter of 160 mm and a length of 1000 mm. The reactor is upright, the treated water flows freely from top to bottom, and the flow rate is stable at 0.46m under the condition of continuous operation for 20 days 3 / h, the removal rate of heavy metals in the outlet water of the municipal sewage treatment plant reached 94%, the removal rate of organic pollutants reached 96%, and the killing rate of microorganisms reached 98%.
[0038] After testing, the effect of removing heavy metals from the above fiber materials is obtained, as shown in the following table:
