Abstract

The invention discloses soil remediation composition and an application thereof. The soil remediation composition is prepared from, in parts by weight, 15-22 parts of fermentation microorganism colonies, 5-13 parts of an ammonium sulfate solution with the concentration of 19-22 mol / L, 3-8 parts of a calcium phosphate solution with the concentration of 15-19 mol / L, 3-6 parts of potassium permanganate and 11-15 parts of a potassium nitrate solution with the concentration of 5-12 mol / L. According to the soil remediation composition and the application thereof, harmful substances in soil can be effectively decomposed through combined bacteria of soil bacteria, soil actinomycete and soil fungi, and the soil remediation effect is realized.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil restoration composition and its application. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. According to the "National Soil Pollution Survey Bulletin" released in 2014, the overall soil environment in China is not optimistic, and the national soil pollution rate has reached 16.1%. While the soil environment problems of industrial and min...
