Abstract
The invention provides an organic sludge soil repairing agent, a preparing method and application of the organic sludge soil repairing agent to sludge adsorption. According to the adopted technical scheme, early treatment is conducted on urban sewage sludge, and harmless treatment is conducted through microorganism. Through the test, after the sludge repairing agent is used for 1-6 months, and the proportion effective removal rate of various pollutants in the soil reaches 95% or above and meets the national standard. Meanwhile, fermentation products can acidize hardened salt and alkali soil and are very good organic fertilizer, agricultural production is benefited, usage of chemical reagents and chemical fertilizer is reduced, and a pollution source and secondary pollution are eradicated from the source.
Description
technical field [0001] The invention relates to an organic sludge soil remediation agent, in particular to a method for preparing an organic soil remediation agent by treating sludge with microorganisms, the obtained organic sludge soil remediation agent, and its application in sludge digestion. Background technique [0002] Pollution caused by toxic organic substances has caused particularly serious harm in recent years, and many organic substances are carcinogenic, teratogenic, and mutagenic substances. According to relevant data from the United States, among the 2,211 organic compounds detected in various water bodies, 117 are considered or suspected to be carcinogens. Among the priority pollutants regulated by the U.S. Environmental Protection Agency (EPA), organic compounds account for 88% of the total, and these organic compounds are all toxic organic substances. Toxic organic substances mainly include various organic pesticides, organic pigments and dyes, aromatic am...
