Embodiment 1

[0025] The slightly polluted source water simulated by phenol was prepared, and the initial content of phenol in the slightly polluted source water was 10mg / L. Pour the slightly polluted source water into the photochemical reaction pool with light source installed in parallel, and then put H into the photochemical reaction pool. 2 o 2 and activated carbon fiber ACF, then pass into ozone, and turn on the light source to carry out ultraviolet irradiation treatment while passing into ozone, and the treatment time is 30 minutes. The removal rate of phenol can reach about 85%.

[0026] like figure 1 As shown, when the two technologies are used together, the pollutant removal rate is significantly improved compared with the single use of the two technologies.

Embodiment 2

[0028] Formulated Fe 3+ The simulated slightly polluted source water, the Fe in the slightly polluted source water 3+ The initial content is 20mg / L. Pour the slightly polluted source water into a photochemical reaction tank with a light source installed in parallel, and then put H into the photochemical reaction tank. 2 o 2 and activated carbon fiber ACF, then pass into ozone, and turn on the light source to carry out ultraviolet irradiation treatment while passing into ozone, and the treatment time is 30 minutes. Depend on figure 2 It can be seen that after treatment, Fe 3+ The removal rate can reach about 90%. Among them, the H of this embodiment 2 o 2 The dosage of ACF is 20mg / L, the dosage of ozone is 5mg / L, and the dosage of ACF is 200mg / L. The light source is a 300W medium pressure mercury lamp.

[0029] According to the above experimental results, UV / (H 2 o 2 +O 3 ) and activated carbon fiber (ACF) have a good synergistic effect, which can effectively remove...

Abstract

The invention discloses a method for treating micro-polluted source water. By the method, organic pollutants and metal ions in the micro-polluted source water can be effectively removed; and the water treatment method can be used for treating the micro-polluted source water on a large scale and is high in treatment efficiency, low in treatment cost and high in application value. The technical key point is that: a UV/(H2O2+O3) advanced oxidation technology and an activated carbon fiber (ACF) are subjected to combined application, so that catalytic oxidation and adsorption are performed simultaneously; and the combined application is that the H2O2 and the ACF are added into the source water to be treated simultaneously, and ultraviolet (UV) degradation is performed while O3 is introduced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method for treating slightly polluted source water. Background technique [0002] Water is a precious natural resource and the material basis for the survival of human beings and all living things. Total global water storage is estimated at 13.9×10 17 m 3 , but the total amount of fresh water only accounts for 2.53%, which is 0.36×10 17 m 3 . 69% of fresh water resources are glaciers, mainly located in the poles and high mountain areas of the earth; the fresh water that can be directly used by people mainly exists in the form of surface water and shallow groundwater, and the reserves are less than 0.3% of the global fresh water. [0003] The per capita share of fresh water resources in my country is 2340m 3 , about 1 / 4 of the world's per capita water, is listed as one of the 13 most water-poor countries, and more than 400 of the country's 668 cities are short of w...
