Abstract

The invention discloses a method for removing heavy metals in water by using an adsorption agent Orient Green, which comprises the following steps: (1) taking sewage polluted by heavy metals, puttingthe sewage into a white bottle, and diluting the sewage for later use; (2) adding an adsorption agent into the sewage treated in the step (1), and adjusting the pH value of the mixed solution; (3) putting the bottle filled with the sewage and the adsorption agent Orient Green in the step (2) into a shaking table, and shaking at room temperature; and (4) after the reaction is balanced, filtering the supernate, transferring the supernatant into a dry and clean glass tube, measuring the change of the concentration of heavy metals in the sewage, and directly discharging the sewage if the requirement is met; and if the discharge requirement is not met, continuing to add Orient Green into the sewage, and repeating the steps until the discharge requirement is met. The components of the adsorptionagent Orient Green are natural, secondary pollution cannot be caused, and the economy and high efficiency are realized; and pollutants in water are removed through an adsorption method, the method issimple, the remediation period is short, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for removing heavy metals in water by using an adsorbent Orient Green. Background technique [0002] With the acceleration of industrialization and modernization, Cr(VI) and Ni(II) in water gradually enter the environment through wastes discharged from industries such as metal processing, smelting, chemical industry, etc., resulting in increasingly serious water pollution. In remediation, reducing agents are usually used to reduce Cr(VI) to less toxic trivalent chromium, and to reduce toxic Ni(II) to low-toxic zero-valent nickel, thereby alleviating Cr(VI) and Ni( II) Pollution. Today, the remediation technologies for heavy metal pollution in water mainly include biological methods, ion exchange and membrane separation. [0003] In the past, a magnetic porous carbonaceous material using tea as raw material was synthesized by a combination of biosorption and py...
