JINLING DRYING

Due to the limitations of site selection for existing water plants, transportation to long-distance landfills is generally far away, especially in mountainous areas where it is more troublesome. Due to the poor carrying capacity of sludge landfill and secondary pollution, many landfill sites are basically unwilling to recycle or increase disposal costs. Meanwhile, the indiscriminate burning or disposal of biomass straw and other materials seriously affects the environment and leads to resource waste. In response to this series of issues, combined with the urban-rural structure, our company has developed various sludge biomass collaborative treatment technologies and equipment, which comprehensively solve the problems of sludge harmless treatment and straw incineration in terms of practicality, stability, reliability, efficiency, and energy conservation and environmental protection. It is possible to design independent or stable collaborative treatment with household waste gasification cycle.

Small and medium-sized municipal water treatment plants produce less sludge. Taking a municipal water plant with a capacity of 20000 tons per day as an example, the daily production of dehydrated sludge is about 6-10 tons.

The company specializes in designing a variety of relatively new drying equipment for slag fiber materials, while providing guarantees for subsequent pyrolysis and gasification stabilization treatment.

Sludge is mainly composed of low-level organic compounds such as amino acids, humic acid, bacteria and their metabolites, polycyclic aromatic hydrocarbons, heterocyclic compounds, organic sulfides, volatile odors, organic fluorides, etc. In addition, it also contains inorganic substances and heavy metal substances such as mercury, cadmium, and lead. Sludge is a by-product with a large volume generated from sewage treatment, generally with a moisture content of 80-90%. For every 10000 cubic meters of sewage treatment capacity, more than 10 tons of sludge can be produced (calculated based on sludge with a moisture content of 80-90%).
