Modular intelligent in-situ active purification system for underground water of uranium tailing pond

Abstract

The invention provides a modular intelligent in-situ active purification system for underground water of a uranium tailing pond. The purification system comprises an underground purification unit andan overground control unit, the underground purification unit comprises a plurality of modular purification columns which are perpendicular to the water flow direction and are arranged in the purification area; the overground control unit comprises a plurality of water suction pumps connected with the modular purification columns and an Internet of Things information console connected with the water suction pumps; and the Internet of Things information console regulates and controls the water pressure in the modular purification columns by controlling the operation of the water suction pumps.In this way, the service life of the purification system can be effectively prolonged, and meanwhile the operation cost is greatly reduced; and the operation state of the water suction pump is controlled through the Internet of Things console, intelligent regulation and control over the water pressure in the modular purification column are achieved, then active purification of underground water isachieved so as to adapt to complex underground water conditions, the utilization efficiency of filler is improved, and high practical application value is achieved.

Description

technical field [0001] The invention relates to the technical field of groundwater environment restoration, in particular to a modular intelligent in-situ active purification system for groundwater in uranium tailings storage. Background technique [0002] According to incomplete statistics, the total amount of uranium tailings in the world has reached 30 billion tons. The long-term accumulation in various types of land conditions has produced a large amount of low-concentration acidic underground wastewater containing uranium and other radionuclides, causing damage to the surrounding environment. Huge security risk. Unlike the high-concentration spent fuel circulating waste liquid treated by the high-cost ex-situ ion extraction technology, the uranium tailings pond has a large amount of groundwater, strong environmental mobility, diverse landforms and highly toxic radionuclides such as uranium The concentration is relatively low, and it is more economical and reasonable to...

Problems solved by technology

However, when the system adjusts the output of the repairing agent, it is difficult to make the agent fully react with the sewage, resulting in a large consumption of repairing agent, and the components of the water repairing agent are not easy to replace, resulting in a longer service life of the water purification system. Low, water purification efficiency is not high
