It is well known that sludge is a muddy substance left after urban sewage meets the discharge standards. Sludge contains not only a large amount of beneficial substances such as organic matter, nitrogen, phosphorus, potassium, but also toxic and harmful substances such as heavy metals. Traditional disposal methods such as landfill, incineration, and building materials utilization not only waste organic matter and resources such as nitrogen, phosphorus, and potassium in sludge, but also easily cause secondary pollution to the ecological environment. In recent years, with the continuous expansion of the urban framework and the continuous increase of urban population, the scale of sewage treatment is increasingly expanding, and the amount of sludge generated at the end of sewage treatment is becoming increasingly high. Therefore, it is urgent to conduct harmless localization and disposal of sludge. Adhering to the "green development concept"
Sludge treatment is a process of sludge reduction, stabilization, and harmless treatment. With the improvement of wastewater treatment rate, more sludge is generated, which requires sludge treatment. In addition to using land or sewage tanks to treat sewage, general sludge treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal has become a complex and expensive process in the operation of sewage treatment systems. Currently, sludge disposal technologies and processes are developing vigorously everywhere. Therefore, under the requirements of harmless treatment and resource utilization, it is particularly important to improve the treatment effect as much as possible. The application of sludge treatment technology in the renovation of sewage treatment plants has broadened the avenues for sludge incineration, cement kiln collaborative treatment, and participation in soil remediation.
Sludge fermentation for organic fertilizer treatment is a promising treatment method due to its low investment, low energy consumption, low operating costs, and the ability to convert some organic matter into soil conditioner components. The moisture content of sludge after dehydration is 78%, and it can reach 30% after drying. The organic matter in sludge is converted into humus rich in plant nutrients by using the sludge organic fertilizer fermentation tank, which produces metabolic products such as CO2, HO2, and heat, so that the sludge can maintain a high temperature of 60 degrees, reduce material accumulation, effectively remove pathogenic microorganisms, parasitic eggs, and weed seeds, and achieve the purpose of volume reduction, stability, harmless, and resource utilization.
The organic fertilizer fermentation tank has a high degree of mechanization, and can be operated by one button and one person for feeding, discharging, and temperature control, which can save a lot of labor and processing costs. Energy conservation and environmental protection of organic fermentation tanks mainly utilize microbial thermal power to assist in electric energy, atomization and deodorization, which can fully meet the emission standards, greatly reduce harmful gas emissions and environmental pollution, and fully meet the requirements of modern green ecological environmental protection. By adopting conventional fermentation processes, the organic fertilizer fermentation tank occupies a small area, saving investment for farms or organic fertilizer factories on site, expanding the space for material fermentation, and winning significant economic benefits for manufacturers, which is also conducive to large-scale production.
