Problems solved by technology

However, the composition of activated sludge is relatively complex, the water content is high, and the treatment is difficult, especially for heavy metals. If they are directly buried without treatment, they will pollute soil and groundwater resources, easily cause new secondary pollution, and cause serious damage to the environment. harm

Embodiment 1

[0064] Activated sludge is a secondary sewage treatment plant in cities and towns that uses biological methods to convert high-energy pollutants into low-energy substances, transforming high-energy organic matter into carbon dioxide and water, while the remaining organic matter and bacteria use carbon sources to carry out life activities and The reproduction of offspring will lead to the proliferation of microorganisms and the activated sludge generated during the treatment operation. It is mainly composed of aerobic microorganisms and does not contain large particles. A kind of high semi-solid waste, after mechanical dehydration until the water content is 45%, 48%, 50%, 53%, 55%; grasp the material into agglomerates without water droplets, loosen the material and the activated sludge will be dispersed use;

[0065] The construction waste is the waste slag discharged during the construction of urban municipal engineering and the waste slag generated in the construction of the...

Abstract

The invention relates to medium soil produced prepared from active sludge building waste residue and a production method of the medium soil. The production method of the medium soil is characterized by comprising the following steps of: uniformly mixing active sludge, quick lime, ferrous sulfate and magnesium sulfate, carrying out deodorization, sterilization and chelation, drying and crushing; then, carrying out dynamic type high-temperature aerobic fermentation on the crushed mixture, forestry three-residue waste residue, peanut shells and an organic material decomposition agent; drying, grinding and screening the fermented mixed clinker to prepare mixed powder; uniformly mixing the mixed powder with raw materials including building waste residue soil, calcium hydrophosphate, ammonium nitrate, potassium sulphate, amino acid, a root growth promoting agent, potassium polyacrylate and soil improvement agent by utilizing a stirrer and drying, then, packaging into an active sludge building waste residue medium soil product by adopting a full-automatic electronic metering machine. The product has the advantages and effects of containing nitrogen, phosphor, potassium and various trace elements as well as various nutrients of organic acid for meeting the growth needs of plants, having no pollution, low cost and good benefits, and protecting the environment, and saving the land.

Description

technical field [0001] The invention relates to a kind of medium soil produced by using activated sludge construction waste soil, specifically, it is the activated sewage produced in the process of converting high-energy pollutants into low-energy substances by biological methods in secondary sewage treatment plants in cities and towns. Mud, the medium soil produced from the powder after mechanical dehydration, drying, grinding and screening, construction waste, forestry three residues and peanut shells as the main raw materials, belongs to the field of waste treatment. [0002] The invention also relates to a method for making the medium soil. Background technique [0003] With the acceleration of my country's urbanization process and the improvement of environmental quality standards, the treatment rate and degree of urban sewage will increase year by year, and the construction and operation of a large number of sewage treatment plants will make my country's urban sludge p...
