Abstract

The invention discloses a method for mixing a heavy metal ion adsorbent and contaminated soil. The method comprises the following steps that the contaminated soil and the heavy metal ion adsorbent areput into a pulverizer for preliminary uniform mixing, then high-strength uniform mixing is carried out after the mixture enters a ball-milling stirrer through an opening, and the mixture enters a second material conveying pipe through a net-shaped opening. According to the method for mixing the heavy metal ion adsorbent and the contaminated soil, the ball-milling stirrer is adopted to realize high-uniformity mixing of the contaminated soil and the heavy metal ion adsorbent, the pulverizer is connected to the upper part of the ball-milling stirrer, so that the transfer time can be shortened, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the field of mixing methods, in particular to a mixing method of a heavy metal ion adsorbent and polluted soil. Background technique [0002] Soil is an important part of the earth's ecological environment, and it is also the natural basis for human survival and development for thousands of years. However, with the continuous development of human society, the area of ​​human activities continues to expand, and urban pollution, industry, mining and agriculture cause heavy metal pollution in the soil. The heavy metals that cause soil pollution are mainly toxic and biologically harmful elements, such as mercury (Hg), lead (Pb), cadmium (Cd), chromium (Cr) and metalloid arsenic (As); and some have certain toxicity elements, such as copper (Cu), zinc (Zn), nickel (Ni), etc. These heavy metal pollutants have poor mobility in the soil, long residence time and are difficult to be degraded by microorganisms. In addition to possibly de...
