Heavy metal ion stabilizer for ecological environment and environment restoration method

Abstract

The invention relates to a heavy metal ion stabilizer for an ecological environment and an environment restoration method. Bentonite is modified in a conventional mode by taking water soluble aluminum salts as a bentonite modifier, thereby preparing aluminum salt modified bentonite taken as the low-concentration heavy metal ion stabilizer for the ecological environment, wherein the adding amount of the modifier accounts for 2% to 30% of the mass of the bentonite. The invention further provides the method for environment restoration by using the heavy metal ion stabilizer. The heavy metal ion stabilizer is wide in source and low in cost, and cannot generate biotoxicity, thereby preventing additional environmental burdens as well as soil solidification and ridging. In addition, the heavy metal ion stabilizer can be used for actively corroding and sucking metal ions while avoiding plant root systems.

Description

technical field [0001] The present invention relates to a heavy metal ion stabilizer used in the ecological environment and a restoration method for the ecological environment in polluted areas, in particular to a low-concentration heavy metal stabilizer in natural ecological areas and the environmental restoration of hidden dangerous ecological areas polluted by heavy metals technology. Background technique [0002] The development of human civilization, the development and deep processing of various resources, and the vicious pollution and accumulation of heavy metal elements in the ecological environment caused by human production and life are becoming more and more serious. It has already shown that it is harmful to the biological chain of the ecological environment. Human beings at the top have caused obvious harm, such as "Minamata disease" in Japan, high incidence of cancer in China, and lesions and even death to human liver, kidney, nervous system, and blood system,...
