Organic polluted soil remediation fertilizer

Abstract

The invention discloses organic polluted soil remediation fertilizer which is prepared from, by weight, 10-12 parts of shell powder, 23-25 parts of bone meal, 5-6 parts of polyaspartic acid, 14-16 parts of powdered straw sugar, 1-3 parts of potassium chlorate, 2-3 parts of compound sodium nitrophenolate, 34-36 parts of eucalyptus saw powder, 13-14 parts of siderite slag, 13-14 parts of limonite slag, 55-60 parts of orange peel, 5-6 parts of EM compound microorganism bacterium agents, and an appropriate amount of water. The soil remediation fertilizer is applicable to deodorization and soil regeneration for soil polluted by waste in a brewery, a slaughter factory, a livestock farm and the like, water and oil in the pollutant are adsorbed and gathered through organic strong adsorption materials such as the shell powder and the bone meal, and microbial decomposition is carried out in an auxiliary mode, so that the ecological environment of the polluted soil is greatly improved, pathogenic bacteria breeding is prevented, the improved soil can be used as a seedling culture substrate, and the utilization value of the improved soil is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for repairing organic polluted soil. Background technique [0002] With the rapid development of the economy and the advancement of industrial technology, the adverse impacts of industrial and agricultural production on the environment have been increasing. Due to the continuous accumulation and dumping of solid waste on the soil surface, harmful waste water has continuously penetrated into the soil, harmful gases and dust in the atmosphere It also continues to fall into the soil with rainwater, causing soil pollution. It not only reduces the yield and quality of crops, but also indirectly endangers human health. [0003] The control of soil pollution is mainly through engineering restoration methods and phytoremediation methods, of which engineering restoration methods mainly include soil improvement methods, electric restoration, soil leaching and heat treatme...

Problems solved by technology

Not only reduces the yield and quality of crops, but also indirectly endangers human health

[0003] The control of soil pollution is mainly through engineering restoration methods and phytoremediation methods, of which engineering restoration methods mainly include soil improvement methods, electric restoration, soil leaching and heat treatment methods, etc. Engineering treatment measures are usually suitable for small polluted areas and serious pollutants. And the effect of the soil that is easy to spread is more obvious, which can fundamentally improve the soil, but the cost of treatment is high, and it is easy to form secondary pollution, and may damage the soil structure, which may easily lead to a decline in soil fertility

Phytoremediation technology is usually low-cost and can improve soil organic matter content and soil fertility, but plants have limited tolerance to heavy metal pollutants and are only suitable for moderately polluted soil remediation. At the same time, a plant can usually only remediate a certain heavy metal pollution Soil, and it is possible to activate other heavy metals in the soil. It is not effective for the compound pollution of various metals and organic substances. Hyperaccumulators grow slowly, and the restoration period is usually long, which is difficult to meet the requirements of rapid restoration of soil pollution.
