Problems solved by technology

[0003] Nearly 1 / 5 of China's existing cultivated land is polluted to varying degrees. Polluted soil will lead to crop yield reduction, and may even cause excessive pollutants in agricultural products, which will endanger human health. In addition, with the acceleration of economic development and urbanization, industrial and mining The site pollution caused by enterprises is also very serious. Due to the changes and adjustments of industrial structure and urban layout, some polluting enterprises such as chemical industry and metallurgy have relocated one after another, and polluted sites continue to be produced. Soil is an important material basis for human social production activities and is indispensable. Natural resources that are difficult to regenerate, and untreated polluted sites are chemical time bombs. Once a large-scale outbreak occurs, it will have an incalculable impact on the sustainable development of the country. Therefore, we must attach great importance to the prevention of soil pollution and the restoration of polluted soil, because there are Necessary to be properly managed and restored so that it can be used rationally

Abstract

The invention discloses a soil remediation agent which comprises the following components in parts by mass: 10-15 parts of livestock and poultry manure, 20-30 parts of corn straw, 5-10 parts of riversand, 10-13 parts of calcium carbonate, 8-11 parts of ground phosphate rock, 5-8 parts of calcium silicate, 5-8 parts of starch, 3-5 parts of clay minerals, 30-38 parts of biomass, 10-13 parts of shell powder, 5-7 parts of a stabilizer, 0.4-0.8 parts of isatis root, 0.5-0.8 part of dandelion, and 0.2-0.4 part of traditional Chinese medicine cane. the remediation agent can effectively remediate soil and improve the soil environment and is good in treatment effect, low in treatment cost and environmentally friendly in raw materials.

Description

technical field [0001] The invention relates to a repairing agent, in particular to a soil repairing agent and a repairing method thereof. Background technique [0002] The soil is originally a natural shelter and purification treatment place for various wastes. The soil accepts pollutants, which does not mean that the soil is polluted. Only when the soil contains too many pollutants, it affects and exceeds the self-purification ability of the soil. , thus having a harmful effect on hygiene and epidemiology, the surface soil is polluted, and there are many reasons for soil pollution, such as industrial sludge, garbage for agriculture, sewage irrigation, and the deposition of pollutants in the atmosphere. Mineral fertilizers and pesticides containing heavy metals, etc. [0003] Nearly 1 / 5 of China's existing cultivated land is polluted to varying degrees. Polluted soil will lead to crop yield reduction, and may even cause excessive pollutants in agricultural products, which ...
