Problems solved by technology

This method has the advantage of faster processing speed than physical and microbial treatment methods, but the use of acid solution to treat organic waste, because the particles of organic waste materials are not uniform, so the treatment is not uniform, which affects product quality
It will also cause heavy metals and other substances in organic pollutants to dissolve into organic materials, which are not easy to separate, and will cause great corrosion of equipment

Abstract

The invention relates to a perishable organic matter oxidizing agent, a treatment system and a method for preparing humic acid-contained fertilizers, and belongs to the field of treating perishable organic wastes and agricultural fertilizers by chemical-biological methods; and perishable organic matters comprise dehydrated sludge in sewage plants, fermented mushroom residues and animal dung. The perishable organic matter oxidizing agent consists of H2O2 solution and an alkaline protective agent, wherein the alkaline protective agent is used for inhibiting H2O2 from forming a Fenton reagent. The treatment system comprises an H2O2 oxidation unit, a biological acidification unit connected with the H2O2 oxidation unit, and a solid-liquid separator connected with the biological acidification unit. A green chemical oxidation technology and a biological acidification leaching technology are combined to degrade heavy metals and residual antibiotics in the perishable organic wastes so as to realize the stabilization treatment of the perishable organic wastes; the produced humic acid-contained fertilizers change wastes into wealth; the content of the heavy metals is lower than the latest national standard limit requirement; and the whole improvement effect on the ecological environment is prominent.

Description

technical field [0001] The invention belongs to the field of treating perishable organic wastes and agricultural fertilizers by chemical-biological methods, and in particular relates to perishable organic oxidizers, a treatment system and a method for preparing humic acid-containing fertilizers. Background technique [0002] Humic acid from organic minerals is humic acid prepared from mineral raw materials including weathered coal, lignite, peat, etc., referred to as coal humic acid or peat humic acid [0003] Non-mineral biomass humic acid (humic acid from nom-mineral biomass) is a by-product of agricultural and forestry production, organic residues of industrial production, waste liquid, etc., as raw materials, humic acid prepared by biotechnology and physical and chemical technology. Referred to as biological humic acid or biochemical humic acid. [0004] The biological treatment method mainly adopted by my country's urban domestic sewage treatment plants is the activate...
