Abstract

The invention discloses a microorganism passivator for repairing heavy metal pollution of soil and preparation and application thereof. A preparing method comprises the steps of fermentation and adsorption of strains. Specifically, bacteria solutions obtained after fermentation of bacillus megateriumvar.phosphaticum and bacillus subtilis LVLE-14 are mixed in proportion, then adsorption is conducted by means of a special adsorption carrier, and then mixing and smashing are conducted to obtain the microorganism passivator. The adsorption carrier comprises hydrolysis residues and biochar which are mixed and smashed according to a certain mass ratio. By the adoption of the microorganism passivator for repairing heavy metal pollution of soil, the content of available heavy metals in soil can be effectively reduced, and the number of microbial populations and plant yield are increased greatly. The method for repairing heavy metal pollution of soil by means of the microorganism passivator is in-situ repair, operation is easy, the cost is low, and industrialized implementation can be easily achieved; furthermore, the repairing effect is good, soil fertility can not be damaged, and the utilization rate of resources can be increased.

Description

technical field

[0001] The invention relates to the technical restoration field of soil microorganisms, in particular to a microbial passivator for repairing heavy metal pollution in soil and its preparation and application. Background technique

[0002] Due to the extensive use of industrial "three wastes", sewage irrigation, agricultural sludge and agricultural inputs containing heavy metals, soil heavy metal pollution has become increasingly serious and has become one of the major environmental problems in my country. Among the eight heavy metal elements such as cadmium (Cd), arsenic (As), lead (Pb), mercury (Hg), chromium (Cr), copper (Cu), zinc (Zn), nickel (Ni)), Cd, As It is highly toxic and has been classified as a Class I carcinogen by the International Agency for Research on Cancer (IARC). According to the "National Soil Pollution Survey Bulletin" jointly issued by the Ministry of Environmental Protection and the Ministry of Land and Resources in 2014, my country'...
