Abstract

The invention discloses a novel adsorption column for removing heavy metals and a preparation method of the adsorption column. Recovered waste sodium alginate gel and environment-friendly resin are combined, artificial stones are formed, and the adsorption column is further prepared. The adsorption column has the effect of adsorbing heavy metal ions, the adsorption column which has certain space and is formed by a top cover, a strip-shaped cage body and a bottom plate can be filled with other adsorption gel capsule materials for removing the heavy metal ions, and the problem that the gel capsule materials cannot be recovered after heavy metal adsorption is solved. Tightening ring parts of the adsorption column are used for fixing the body of the adsorption column so as to prevent the adsorption column from falling apart. Recovery, regrinding and sample preparation can be performed after the adsorption column is damaged during adsorption, and recycling is realized. The novel adsorption column for removing the heavy metals has excellent performance such as high mechanical strength, good pollution resistance, acid and alkali corrosion resistance and the like and has very high commercial exploitation value, and secondary pollution can be avoided fundamentally.

Description

technical field [0001] The invention belongs to the technical field of sewage sludge treatment, and in particular relates to a novel adsorption column for removing heavy metals and a preparation method thereof. Background technique [0002] The rapid development of my country's industrial manufacturing industry, on the one hand, has promoted the growth of the national economy, on the other hand, it has also brought a large amount of industrial wastewater, which generally contains a large amount of chemical toxic elements, heavy metal ions, etc., causing environmental pollution and affecting human health. There are two main ways to capture heavy metals in sewage sludge. [0003] (1) Use heavy metal scavengers. [0004] The heavy metal scavenger is a reagent that strongly chelates heavy metal ions, reacts with various heavy metal ions in sewage sludge, and quickly generates flocculent precipitates that are easy to filter and remove, achieving the purpose of removing heavy met...
