Problems solved by technology

[0005] At present, the most commonly used adsorbents are activated carbon and modified cellulose, etc., but most of the adsorbents are affected by the high cost, complicated production process or the degree of refinement of the adsorbent particles due to the high cost of the adsorbent. The key of the dynamic adsorption technology lies in the adsorbent selection and use of

Embodiment

[0023] (1) A device for purifying heavy metal ions in water is set, such as figure 1 As shown, it includes an automatic pH adjustment system 1 for the liquid to be treated, a quantitative and fixed-speed lifting system 2 for the liquid to be treated, a reaction temperature control system 3, a stationary phase dynamic adsorption reaction system 4, and a treated water collection system 5. The above systems are set up in sequence, and All are installed on the fixed support platform 6.

[0024] The pH value automatic adjustment system 1 of the liquid to be treated is composed of an acid liquid tank 7, an alkali liquid tank 8, a pH value adjustment controller 9 and a pH value probe 10; the required pH value is set, and the real-time measured value of the pH value probe 10 is compared with the pH value. In contrast, if the pH value measured by the pH probe 10 is lower than the set value, the peristaltic pump head of the acid liquid tank 7 is started, and weak acid is added to adjust...

Abstract

The invention discloses a method for dynamically adsorbing and purifying heavy metal ions in water. With the adoption of a water flowing control technology with an adsorbent as a stationary phase, by virtue of ingenious design of a stationary phase filtration column, an efficient dynamical adsorption condition is conveniently and effectively controlled, the technical method for dynamically adsorbing and purifying the heavy metal ions in the water is integrated, and a novel method and way is provided for effectively and efficiently controlling heavy metal pollution emergency disposal and micro-pollution of heavy metals in rivers and lakes. As micro-pollution treatment is carried out on the rivers and the lakes with the heavy metal ions as main pollutants, except efficient heavy metal ion removing effect, the method also has certain pollution accident emergency function. In addition, the method has the advantages of stable running process of device, low energy consumption, low running cost and the like.

Description

technical field [0001] The invention belongs to the technical field of waste resource utilization and water treatment, in particular to a method for dynamically absorbing and purifying heavy metal ions in water. Background technique [0002] Water is one of the resources that human beings rely on for survival, and it is closely related to the sustainable development of society. Today, the wanton destruction of the environment by humans has seriously affected the natural ecosystems of the earth, and the water pollution of heavy metals / heavy metals represented by arsenic, chromium and antimony is particularly prominent. At present, the removal methods of heavy metals in water mainly include chemical precipitation method, electric flotation method, ion exchange method, membrane separation method and adsorption method. Among them, the adsorption method has the advantages of quick effect, reproducible recovery, and low probability of secondary pollution. valued. [0003] The co...
