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.
