Abstract

The invention discloses a heavy metal soil remediation agent which comprises the following substances in parts by mass: 4-8 parts of a biological agent, 10-20 parts of turf powder, 15-25 parts of compost, 10-18 parts of hydroxyapatite powder, 3-6 parts of a surfactant and 5-10 parts of manganese dioxide. The remediation agent is sprayed after being mixed with water, and the mass ratio of the remediation agent to the water is 1: 6. The polypeptidase is thrombolytic fiber kinase. The remediation agent is matched with plants for repairing, and the plants comprise lalang grass, digitaria sanguinalis, horseweed herb, arbor, equisetum ramosissimum, ciliate desert-grass and miscanthus floridulus. The biological agent comprises at least one of a silicate microbial agent, a rhizobium microbial agent and pseudomonas fluorescens. The compost comprises crop straws, weeds, leaves, peat, organic household garbage, kitchen waste, sludge, human and animal manure and urine, vinasse and mushroom bran. The remediation agent can passivate heavy metals, reduce the activity of the heavy metals and improve the soil production capacity.

Description

technical field [0001] The invention belongs to the technical field of contaminated soil treatment, and in particular relates to a remediation agent for heavy metal polluted soil. Background technique [0002] With the acceleration of industrialization in our country and the continuous improvement of the level of economic development, it is also accompanied by the emergence of more serious soil pollution problems. Among them, heavy metal pollution is particularly serious, which poses a serious threat to people's health. The soil environment problems in our country are very serious, among which the environmental problems of industrial and mining abandoned land are particularly important. According to the published survey results, the national soil exceeding the standard rate reached 16.1%. According to the degree of pollution, the proportion of heavily polluted sites is 1.1%, the proportion of moderately polluted sites is 1.5%, the proportion of lightly polluted sites is 2....
