Process and device for movably adsorbing poisonous and harmful substances in natural water areas

Abstract

The invention provides a process and a device for movably adsorbing poisonous and harmful substances in natural water areas. The movable adsorption process comprises that: when a river is polluted by poisonous and harmful substances and needs to be treated, firstly, the polluted water area is isolated from the unpolluted water area; and secondly, the adsorbing materials capable of adsorbing poisonous and harmful substances are dragged to move in the water body of the polluted water area for movable adsorption, so that the aim of quickly purifying water is achieved. The movable adsorption device comprises a movable adsorption unit module consisting of a bracket, adsorbing materials and floaters, wherein the adsorbing materials are put in meshed bags which are staggered and hanged on the bracket, and the bracket is connected with the floaters. The process and the device have the advantages that the concentration diffusion adsorbing path is short; the movement of the movable adsorption device improves the convective diffusion efficiency and further enhances the adsorption mass transfer effect, so that the contents of the poisonous and harmful substances in the water body can be effectively reduced in a short period of time.

Description

technical field [0001] The invention relates to a technology for removing pollutants in natural waters, in particular to an emergency removal technology for toxic and harmful substances (such as heavy metals, "three-caused" substances, etc.) in natural waters under the background of sudden environmental accidents, belonging to water quality Purification technology field. Background technique [0002] Wastewater discharged from production accidents in chemical companies often contains heavy metals and other toxic and harmful substances (such as arsenic, mercury, lead, cadmium, etc.). It can be increased by more than a million times, and after being eaten by the human body, it often leads to human poisoning. There are two main technologies currently applied to the emergency treatment of sudden pollution in natural waters: one is to add chemicals in the water body, and transfer toxic and harmful substances such as heavy metals to the sediment through sedimentation; Build an a...
