Abstract

The invention discloses a soil heavy metal pollution treatment device with a circulation mechanism, which includes a chemical reaction device, a sedimentation separation tank, an aqueous solution regeneration and circulation device, and a soil structure restoration and granulation device; the aqueous solution regeneration and circulation device includes a regeneration tower, a regeneration tower An aqueous solution condensing device is arranged on the top, and the first input pump and the first output pump are connected on the regeneration tower, and the heavy metal recovery tank is connected to the outlet of the first output pump; several perforated trays are arranged in the regeneration tower, each One end of the tray with holes is provided with a downcomer and the downcomer is staggered; the present invention aims at the combination of heavy metals and solvents to form complexes. When heated, the complexes decompose, and the solvent and part of the water are evaporated for Recycling; heavy metal ions are concentrated at the bottom of the regeneration tower, collected and stored, which is used to solve the problem of secondary pollution caused by chemical treatment of pollutants.

Description

technical field [0001] The invention relates to the field of soil pollution control, in particular to a soil heavy metal pollution control device with a circulation mechanism. Background technique [0002] With the rapid development of my country's industry, agriculture and animal husbandry, on the one hand, it has driven the rapid growth of my country's GDP and entered the global economic power; on the other hand, the discharge of waste, waste residue and waste water in the industry is not up to standard, leading to air and soil pollution; The excessive use of chemical fertilizers for the rapid growth of crops leads to the pollution of soil and water bodies; the discharge of dung and waste water in animal husbandry leads to the pollution of groundwater and surrounding soil. [0003] Soil pollution is mainly the pollution of organic matter and heavy metal substances. These substances will accumulate with the increase of the food chain and eventually enter the human body, enda...
